    device : int
        The device against which the memory was allocated or registered. If

    CUDA function attributes

    Attributes
    ----------
    sharedSizeBytes : size_t
        The size in bytes of statically-allocated shared memory per block
        required by this function. This does not include dynamically-
        allocated shared memory requested by the user at runtime.
    constSizeBytes : size_t
        The size in bytes of user-allocated constant memory required by
        this function.
    localSizeBytes : size_t
        The size in bytes of local memory used by each thread of this
        function.
    maxThreadsPerBlock : int
        The maximum number of threads per block, beyond which a launch of
        the function would fail. This number depends on both the function
        and the device on which the function is currently loaded.
    numRegs : int
        The number of registers used by each thread of this function.
    ptxVersion : int
        The PTX virtual architecture version for which the function was
        compiled. This value is the major PTX version * 10 + the minor PTX
        version, so a PTX version 1.3 function would return the value 13.
    binaryVersion : int
        The binary architecture version for which the function was
        compiled. This value is the major binary version * 10 + the minor
        binary version, so a binary version 1.3 function would return the
        value 13.
    cacheModeCA : int
        The attribute to indicate whether the function has been compiled
        with user specified option "-Xptxas --dlcm=ca" set.
    maxDynamicSharedSizeBytes : int
        The maximum size in bytes of dynamic shared memory per block for
        this function. Any launch must have a dynamic shared memory size
        smaller than this value.
    preferredShmemCarveout : int
        On devices where the L1 cache and shared memory use the same
        hardware resources, this sets the shared memory carveout
        preference, in percent of the maximum shared memory. Refer to
        cudaDevAttrMaxSharedMemoryPerMultiprocessor. This is only a hint,
        and the driver can choose a different ratio if required to execute
        the function. See cudaFuncSetAttribute

def cudaDeviceSetLimit(limit not None : cudaLimit, size_t value):
    """ Set resource limits.

    Setting `limit` to `value` is a request by the application to update
    the current limit maintained by the device. The driver is free to
    modify the requested value to meet h/w requirements (this could be
    clamping to minimum or maximum values, rounding up to nearest element
    size, etc). The application can use :py:obj:`~.cudaDeviceGetLimit()` to
    find out exactly what the limit has been set to.

    Setting each :py:obj:`~.cudaLimit` has its own specific restrictions,
    so each is discussed here.

    - :py:obj:`~.cudaLimitStackSize` controls the stack size in bytes of
      each GPU thread.

    - :py:obj:`~.cudaLimitPrintfFifoSize` controls the size in bytes of the
      shared FIFO used by the :py:obj:`~.printf()` device system call.
      Setting :py:obj:`~.cudaLimitPrintfFifoSize` must not be performed
      after launching any kernel that uses the :py:obj:`~.printf()` device
      system call - in such case :py:obj:`~.cudaErrorInvalidValue` will be
      returned.

    - :py:obj:`~.cudaLimitMallocHeapSize` controls the size in bytes of the
      heap used by the :py:obj:`~.malloc()` and :py:obj:`~.free()` device
      system calls. Setting :py:obj:`~.cudaLimitMallocHeapSize` must not be
      performed after launching any kernel that uses the
      :py:obj:`~.malloc()` or :py:obj:`~.free()` device system calls - in
      such case :py:obj:`~.cudaErrorInvalidValue` will be returned.

    - :py:obj:`~.cudaLimitDevRuntimeSyncDepth` controls the maximum nesting
      depth of a grid at which a thread can safely call
      :py:obj:`~.cudaDeviceSynchronize()`. Setting this limit must be
      performed before any launch of a kernel that uses the device runtime
      and calls :py:obj:`~.cudaDeviceSynchronize()` above the default sync
      depth, two levels of grids. Calls to
      :py:obj:`~.cudaDeviceSynchronize()` will fail with error code
      :py:obj:`~.cudaErrorSyncDepthExceeded` if the limitation is violated.
      This limit can be set smaller than the default or up the maximum
      launch depth of 24. When setting this limit, keep in mind that
      additional levels of sync depth require the runtime to reserve large
      amounts of device memory which can no longer be used for user
      allocations. If these reservations of device memory fail,
      :py:obj:`~.cudaDeviceSetLimit` will return
      :py:obj:`~.cudaErrorMemoryAllocation`, and the limit can be reset to
      a lower value. This limit is only applicable to devices of compute
      capability 3.5 and higher. Attempting to set this limit on devices of
      compute capability less than 3.5 will result in the error
      :py:obj:`~.cudaErrorUnsupportedLimit` being returned.

    - :py:obj:`~.cudaLimitDevRuntimePendingLaunchCount` controls the
      maximum number of outstanding device runtime launches that can be
      made from the current device. A grid is outstanding from the point of
      launch up until the grid is known to have been completed. Device
      runtime launches which violate this limitation fail and return
      :py:obj:`~.cudaErrorLaunchPendingCountExceeded` when
      :py:obj:`~.cudaGetLastError()` is called after launch. If more
      pending launches than the default (2048 launches) are needed for a
      module using the device runtime, this limit can be increased. Keep in
      mind that being able to sustain additional pending launches will
      require the runtime to reserve larger amounts of device memory
      upfront which can no longer be used for allocations. If these
      reservations fail, :py:obj:`~.cudaDeviceSetLimit` will return
      :py:obj:`~.cudaErrorMemoryAllocation`, and the limit can be reset to
      a lower value. This limit is only applicable to devices of compute
      capability 3.5 and higher. Attempting to set this limit on devices of
      compute capability less than 3.5 will result in the error
      :py:obj:`~.cudaErrorUnsupportedLimit` being returned.

    - :py:obj:`~.cudaLimitMaxL2FetchGranularity` controls the L2 cache
      fetch granularity. Values can range from 0B to 128B. This is purely a
      performance hint and it can be ignored or clamped depending on the
      platform.

    - :py:obj:`~.cudaLimitPersistingL2CacheSize` controls size in bytes
      available for persisting L2 cache. This is purely a performance hint
      and it can be ignored or clamped depending on the platform.

    initialized, it is initialized with the provided flags. If no device

    selected and initialized with the provided flags.

    The two LSBs of the `flags` parameter can be used to control how the
    CPU thread interacts with the OS scheduler when waiting for results
    from the device.

    - :py:obj:`~.cudaDeviceScheduleAuto`: The default value if the `flags`
      parameter is zero, uses a heuristic based on the number of active
      CUDA contexts in the process `C` and the number of logical processors
      in the system `P`. If `C` > `P`, then CUDA will yield to other OS
      threads when waiting for the device, otherwise CUDA will not yield
      while waiting for results and actively spin on the processor.
      Additionally, on Tegra devices, :py:obj:`~.cudaDeviceScheduleAuto`
      uses a heuristic based on the power profile of the platform and may
      choose :py:obj:`~.cudaDeviceScheduleBlockingSync` for low-powered
      devices.

    - :py:obj:`~.cudaDeviceScheduleSpin`: Instruct CUDA to actively spin
      when waiting for results from the device. This can decrease latency
      when waiting for the device, but may lower the performance of CPU
      threads if they are performing work in parallel with the CUDA thread.

    - :py:obj:`~.cudaDeviceScheduleYield`: Instruct CUDA to yield its
      thread when waiting for results from the device. This can increase
      latency when waiting for the device, but can increase the performance
      of CPU threads performing work in parallel with the device.

    - :py:obj:`~.cudaDeviceScheduleBlockingSync`: Instruct CUDA to block
      the CPU thread on a synchronization primitive when waiting for the
      device to finish work.

    - :py:obj:`~.cudaDeviceBlockingSync`: Instruct CUDA to block the CPU
      thread on a synchronization primitive when waiting for the device to
      finish work.   :py:obj:`~.Deprecated:` This flag was deprecated as of
      CUDA 4.0 and replaced with
      :py:obj:`~.cudaDeviceScheduleBlockingSync`.

    - :py:obj:`~.cudaDeviceMapHost`: This flag enables allocating pinned
      host memory that is accessible to the device. It is implicit for the
      runtime but may be absent if a context is created using the driver
      API. If this flag is not set, :py:obj:`~.cudaHostGetDevicePointer()`
      will always return a failure code.

    - :py:obj:`~.cudaDeviceLmemResizeToMax`: Instruct CUDA to not reduce
      local memory after resizing local memory for a kernel. This can
      prevent thrashing by local memory allocations when launching many
      kernels with high local memory usage at the cost of potentially
      increased memory usage.   :py:obj:`~.Deprecated:` This flag is

    returned. If there is no current device, the flags for the first device
    are returned, which may be the default flags. Compare to the behavior
    of :py:obj:`~.cudaSetDeviceFlags`.

    Typically, the flags returned should match the behavior that will be
    seen if the calling thread uses a device after this call, without any
    change to the flags or current device inbetween by this or another
    thread. Note that if the device is not initialized, it is possible for
    another thread to change the flags for the current device before it is

    has not requested a specific device, it may use a device other than the
    first device, contrary to the assumption made by this function.

    If a context has been created via the driver API and is current to the

    Flags returned by this function may specifically include
    :py:obj:`~.cudaDeviceMapHost` even though it is not accepted by

def cudaStreamAddCallback(stream, callback, userData, unsigned int flags):
    """ Add a callback to a compute stream.

    Adds a callback to be called on the host after all currently enqueued
    items in the stream have completed. For each cudaStreamAddCallback
    call, a callback will be executed exactly once. The callback will block
    later work in the stream until it is finished.

    The callback may be passed :py:obj:`~.cudaSuccess` or an error code. In
    the event of a device error, all subsequently executed callbacks will
    receive an appropriate :py:obj:`~.cudaError_t`.

    Callbacks must not make any CUDA API calls. Attempting to use CUDA APIs
    may result in :py:obj:`~.cudaErrorNotPermitted`. Callbacks must not
    perform any synchronization that may depend on outstanding device work
    or other callbacks that are not mandated to run earlier. Callbacks
    without a mandated order (in independent streams) execute in undefined
    order and may be serialized.

    For the purposes of Unified Memory, callback execution makes a number
    of guarantees:

    - The callback stream is considered idle for the duration of the
      callback. Thus, for example, a callback may always use memory
      attached to the callback stream.

    - The start of execution of a callback has the same effect as
      synchronizing an event recorded in the same stream immediately prior
      to the callback. It thus synchronizes streams which have been
      "joined" prior to the callback.

    - Adding device work to any stream does not have the effect of making
      the stream active until all preceding callbacks have executed. Thus,
      for example, a callback might use global attached memory even if work
      has been added to another stream, if it has been properly ordered
      with an event.

    - Completion of a callback does not cause a stream to become active
      except as described above. The callback stream will remain idle if no
      device work follows the callback, and will remain idle across
      consecutive callbacks without device work in between. Thus, for
      example, stream synchronization can be done by signaling from a
      callback at the end of the stream.

    Parameters
    ----------
    stream : :py:obj:`~.CUstream` or :py:obj:`~.cudaStream_t`
        Stream to add callback to
    callback : :py:obj:`~.cudaStreamCallback_t`
        The function to call once preceding stream operations are complete
    userData : Any
        User specified data to be passed to the callback function
    flags : unsigned int
        Reserved for future use, must be 0

def cudaStreamAttachMemAsync(stream, devPtr, size_t length, unsigned int flags):
    """ Attach memory to a stream asynchronously.

    Enqueues an operation in `stream` to specify stream association of
    `length` bytes of memory starting from `devPtr`. This function is a
    stream-ordered operation, meaning that it is dependent on, and will
    only take effect when, previous work in stream has completed. Any
    previous association is automatically replaced.

    `devPtr` must point to an one of the following types of memories:

    - managed memory declared using the managed keyword or allocated with
      :py:obj:`~.cudaMallocManaged`.

    - a valid host-accessible region of system-allocated pageable memory.
      This type of memory may only be specified if the device associated
      with the stream reports a non-zero value for the device attribute
      :py:obj:`~.cudaDevAttrPageableMemoryAccess`.

    For managed allocations, `length` must be either zero or the entire
    allocation's size. Both indicate that the entire allocation's stream
    association is being changed. Currently, it is not possible to change
    stream association for a portion of a managed allocation.

    For pageable allocations, `length` must be non-zero.

    The stream association is specified using `flags` which must be one of
    :py:obj:`~.cudaMemAttachGlobal`, :py:obj:`~.cudaMemAttachHost` or
    :py:obj:`~.cudaMemAttachSingle`. The default value for `flags` is
    :py:obj:`~.cudaMemAttachSingle` If the :py:obj:`~.cudaMemAttachGlobal`
    flag is specified, the memory can be accessed by any stream on any
    device. If the :py:obj:`~.cudaMemAttachHost` flag is specified, the
    program makes a guarantee that it won't access the memory on the device
    from any stream on a device that has a zero value for the device
    attribute :py:obj:`~.cudaDevAttrConcurrentManagedAccess`. If the
    :py:obj:`~.cudaMemAttachSingle` flag is specified and `stream` is
    associated with a device that has a zero value for the device attribute
    :py:obj:`~.cudaDevAttrConcurrentManagedAccess`, the program makes a
    guarantee that it will only access the memory on the device from
    `stream`. It is illegal to attach singly to the NULL stream, because
    the NULL stream is a virtual global stream and not a specific stream.
    An error will be returned in this case.

    When memory is associated with a single stream, the Unified Memory
    system will allow CPU access to this memory region so long as all
    operations in `stream` have completed, regardless of whether other
    streams are active. In effect, this constrains exclusive ownership of
    the managed memory region by an active GPU to per-stream activity
    instead of whole-GPU activity.

    Accessing memory on the device from streams that are not associated
    with it will produce undefined results. No error checking is performed
    by the Unified Memory system to ensure that kernels launched into other
    streams do not access this region.

    It is a program's responsibility to order calls to
    :py:obj:`~.cudaStreamAttachMemAsync` via events, synchronization or
    other means to ensure legal access to memory at all times. Data
    visibility and coherency will be changed appropriately for all kernels
    which follow a stream-association change.

    If `stream` is destroyed while data is associated with it, the
    association is removed and the association reverts to the default
    visibility of the allocation as specified at
    :py:obj:`~.cudaMallocManaged`. For managed variables, the default
    association is always :py:obj:`~.cudaMemAttachGlobal`. Note that
    destroying a stream is an asynchronous operation, and as a result, the
    change to default association won't happen until all work in the stream
    has completed.

    stream : :py:obj:`~.CUstream` or :py:obj:`~.cudaStream_t`

    """ Swaps the stream capture interaction mode for a thread.

    Sets the calling thread's stream capture interaction mode to the value
    contained in `*mode`, and overwrites `*mode` with the previous mode for
    the thread. To facilitate deterministic behavior across function or
    module boundaries, callers are encouraged to use this API in a push-pop
    fashion:

    **View CUDA Toolkit Documentation for a C++ code example**

    During stream capture (see :py:obj:`~.cudaStreamBeginCapture`), some
    actions, such as a call to :py:obj:`~.cudaMalloc`, may be unsafe. In
    the case of :py:obj:`~.cudaMalloc`, the operation is not enqueued
    asynchronously to a stream, and is not observed by stream capture.
    Therefore, if the sequence of operations captured via
    :py:obj:`~.cudaStreamBeginCapture` depended on the allocation being
    replayed whenever the graph is launched, the captured graph would be
    invalid.

    Therefore, stream capture places restrictions on API calls that can be
    made within or concurrently to a
    :py:obj:`~.cudaStreamBeginCapture`-:py:obj:`~.cudaStreamEndCapture`
    sequence. This behavior can be controlled via this API and flags to
    :py:obj:`~.cudaStreamBeginCapture`.

    A thread's mode is one of the following:

    - `cudaStreamCaptureModeGlobal:` This is the default mode. If the local
      thread has an ongoing capture sequence that was not initiated with
      `cudaStreamCaptureModeRelaxed` at `cuStreamBeginCapture`, or if any
      other thread has a concurrent capture sequence initiated with
      `cudaStreamCaptureModeGlobal`, this thread is prohibited from
      potentially unsafe API calls.

    - `cudaStreamCaptureModeThreadLocal:` If the local thread has an
      ongoing capture sequence not initiated with
      `cudaStreamCaptureModeRelaxed`, it is prohibited from potentially
      unsafe API calls. Concurrent capture sequences in other threads are
      ignored.

    - `cudaStreamCaptureModeRelaxed:` The local thread is not prohibited
      from potentially unsafe API calls. Note that the thread is still
      prohibited from API calls which necessarily conflict with stream
      capture, for example, attempting :py:obj:`~.cudaEventQuery` on an
      event that was last recorded inside a capture sequence.

    Captures in `event` the contents of `stream` at the time of this call.
    `event` and `stream` must be on the same CUDA context. Calls such as
    :py:obj:`~.cudaEventQuery()` or :py:obj:`~.cudaStreamWaitEvent()` will
    then examine or wait for completion of the work that was captured. Uses
    of `stream` after this call do not modify `event`. See note on default
    stream behavior for what is captured in the default case.

    :py:obj:`~.cudaEventRecordWithFlags()` can be called multiple times on
    the same event and will overwrite the previously captured state. Other
    APIs such as :py:obj:`~.cudaStreamWaitEvent()` use the most recently
    captured state at the time of the API call, and are not affected by
    later calls to :py:obj:`~.cudaEventRecordWithFlags()`. Before the first
    call to :py:obj:`~.cudaEventRecordWithFlags()`, an event represents an
    empty set of work, so for example :py:obj:`~.cudaEventQuery()` would
    return :py:obj:`~.cudaSuccess`.

    flags include:

    - :py:obj:`~.cudaEventRecordDefault`: Default event creation flag.

    - :py:obj:`~.cudaEventRecordExternal`: Event is captured in the graph
      as an external event node when performing stream capture.

    The offset and size have to be suitably aligned to match the

    Otherwise writes made via one address are not guaranteed to be visible

    separate buffers and then apply the appropriate offsets to the returned

    Enqueues a signal operation on a set of externally allocated semaphore
    object in the specified stream. The operations will be executed when
    all prior operations in the stream complete.

    The exact semantics of signaling a semaphore depends on the type of the
    object.

    If the semaphore object is any one of the following types:
    :py:obj:`~.cudaExternalSemaphoreHandleTypeOpaqueFd`,
    :py:obj:`~.cudaExternalSemaphoreHandleTypeOpaqueWin32`,
    :py:obj:`~.cudaExternalSemaphoreHandleTypeOpaqueWin32Kmt` then

    :py:obj:`~.cudaExternalSemaphoreHandleTypeD3D11Fence`,
    :py:obj:`~.cudaExternalSemaphoreHandleTypeTimelineSemaphoreFd`,
    :py:obj:`~.cudaExternalSemaphoreHandleTypeTimelineSemaphoreWin32` then
    the semaphore will be set to the value specified in
    :py:obj:`~.cudaExternalSemaphoreSignalParams`::params::fence::value.

    If the semaphore object is of the type

    :py:obj:`~.cudaExternalSemaphoreSignalParams`::params::nvSciSync::fence
    to a value that can be used by subsequent waiters of the same NvSciSync
    object to order operations with those currently submitted in `stream`.
    Such an update will overwrite previous contents of
    :py:obj:`~.cudaExternalSemaphoreSignalParams`::params::nvSciSync::fence.
    By deefault, signaling such an external semaphore object causes
    appropriate memory synchronization operations to be performed over all
    the external memory objects that are imported as
    :py:obj:`~.cudaExternalMemoryHandleTypeNvSciBuf`. This ensures that any
    subsequent accesses made by other importers of the same set of NvSciBuf
    memory object(s) are coherent. These operations can be skipped by
    specifying the flag
    :py:obj:`~.cudaExternalSemaphoreSignalSkipNvSciBufMemSync`, which can
    be used as a performance optimization when data coherency is not
    required. But specifying this flag in scenarios where data coherency is

    the type :py:obj:`~.cudaExternalSemaphoreHandleTypeNvSciSync`, if the
    NvSciSyncAttrList used to create the NvSciSyncObj had not set the flags
    in :py:obj:`~.cudaDeviceGetNvSciSyncAttributes` to
    cudaNvSciSyncAttrSignal, this API will return cudaErrorNotSupported.

    If the semaphore object is any one of the following types:
    :py:obj:`~.cudaExternalSemaphoreHandleTypeKeyedMutex`,
    :py:obj:`~.cudaExternalSemaphoreHandleTypeKeyedMutexKmt`, then the
    keyed mutex will be released with the key specified in

    If the semaphore object is any one of the following types:
    :py:obj:`~.cudaExternalSemaphoreHandleTypeKeyedMutex`,

    """ Enqueues a host function call in a stream.

    Enqueues a host function to run in a stream. The function will be
    called after currently enqueued work and will block work added after
    it.

    The host function must not make any CUDA API calls. Attempting to use a
    CUDA API may result in :py:obj:`~.cudaErrorNotPermitted`, but this is
    not required. The host function must not perform any synchronization
    that may depend on outstanding CUDA work not mandated to run earlier.
    Host functions without a mandated order (such as in independent
    streams) execute in undefined order and may be serialized.

    For the purposes of Unified Memory, execution makes a number of
    guarantees:

    - The stream is considered idle for the duration of the function's
      execution. Thus, for example, the function may always use memory
      attached to the stream it was enqueued in.

    - The start of execution of the function has the same effect as
      synchronizing an event recorded in the same stream immediately prior
      to the function. It thus synchronizes streams which have been
      "joined" prior to the function.

    - Adding device work to any stream does not have the effect of making
      the stream active until all preceding host functions and stream
      callbacks have executed. Thus, for example, a function might use
      global attached memory even if work has been added to another stream,
      if the work has been ordered behind the function call with an event.

    - Completion of the function does not cause a stream to become active
      except as described above. The stream will remain idle if no device
      work follows the function, and will remain idle across consecutive
      host functions or stream callbacks without device work in between.
      Thus, for example, stream synchronization can be done by signaling
      from a host function at the end of the stream.

    Note that, in constrast to :py:obj:`~.cuStreamAddCallback`, the
    function will not be called in the event of an error in the CUDA
    context.

    ----------
    hStream : :py:obj:`~.CUstream` or :py:obj:`~.cudaStream_t`

    `flags` specifies the default stream association for this allocation.
    `flags` must be one of :py:obj:`~.cudaMemAttachGlobal` or

    :py:obj:`~.cudaMemAttachGlobal`. If :py:obj:`~.cudaMemAttachGlobal` is

    :py:obj:`~.cudaDevAttrConcurrentManagedAccess`; an explicit call to
    :py:obj:`~.cudaStreamAttachMemAsync` will be required to enable access

    If the association is later changed via
    :py:obj:`~.cudaStreamAttachMemAsync` to a single stream, the default
    association, as specifed during :py:obj:`~.cudaMallocManaged`, is

    In a multi-GPU system where all GPUs have a non-zero value for the
    device attribute :py:obj:`~.cudaDevAttrConcurrentManagedAccess`,
    managed memory may not be populated when this API returns and instead
    may be populated on access. In such systems, managed memory can migrate
    to any processor's memory at any time. The Unified Memory driver will
    employ heuristics to maintain data locality and prevent excessive page
    faults to the extent possible. The application can also guide the
    driver about memory usage patterns via :py:obj:`~.cudaMemAdvise`. The
    application can also explicitly migrate memory to a desired processor's
    memory via :py:obj:`~.cudaMemPrefetchAsync`.

    In a multi-GPU system where all of the GPUs have a zero value for the
    device attribute :py:obj:`~.cudaDevAttrConcurrentManagedAccess` and all
    the GPUs have peer-to-peer support with each other, the physical
    storage for managed memory is created on the GPU which is active at the
    time :py:obj:`~.cudaMallocManaged` is called. All other GPUs will
    reference the data at reduced bandwidth via peer mappings over the PCIe
    bus. The Unified Memory driver does not migrate memory among such GPUs.

    In a multi-GPU system where not all GPUs have peer-to-peer support with
    each other and where the value of the device attribute
    :py:obj:`~.cudaDevAttrConcurrentManagedAccess` is zero for at least one
    of those GPUs, the location chosen for physical storage of managed
    memory is system-dependent.

    - On Linux, the location chosen will be device memory as long as the
      current set of active contexts are on devices that either have peer-
      to-peer support with each other or have a non-zero value for the
      device attribute :py:obj:`~.cudaDevAttrConcurrentManagedAccess`. If
      there is an active context on a GPU that does not have a non-zero
      value for that device attribute and it does not have peer-to-peer
      support with the other devices that have active contexts on them,
      then the location for physical storage will be 'zero-copy' or host
      memory. Note that this means that managed memory that is located in
      device memory is migrated to host memory if a new context is created
      on a GPU that doesn't have a non-zero value for the device attribute
      and does not support peer-to-peer with at least one of the other
      devices that has an active context. This in turn implies that context
      creation may fail if there is insufficient host memory to migrate all
      managed allocations.

    - On Windows, the physical storage is always created in 'zero-copy' or
      host memory. All GPUs will reference the data at reduced bandwidth
      over the PCIe bus. In these circumstances, use of the environment
      variable CUDA_VISIBLE_DEVICES is recommended to restrict CUDA to only
      use those GPUs that have peer-to-peer support. Alternatively, users
      can also set CUDA_MANAGED_FORCE_DEVICE_ALLOC to a non-zero value to
      force the driver to always use device memory for physical storage.
      When this environment variable is set to a non-zero value, all
      devices used in that process that support managed memory have to be
      peer-to-peer compatible with each other. The error
      :py:obj:`~.cudaErrorInvalidDevice` will be returned if a device that
      supports managed memory is used and it is not peer-to-peer compatible
      with any of the other managed memory supporting devices that were
      previously used in that process, even if :py:obj:`~.cudaDeviceReset`
      has been called on those devices. These environment variables are
      described in the CUDA programming guide under the "CUDA environment
      variables" section.

    allocate memory that is portable, mapped and/or write-combined with no

      coherent and contiguous.

    - :py:obj:`~.cudaHostRegisterReadOnly`: The passed memory pointer is
      treated as pointing to memory that is considered read-only by the
      device. On platforms without
      :py:obj:`~.cudaDevAttrPageableMemoryAccessUsesHostPageTables`, this
      flag is required in order to register memory mapped to the CPU as
      read-only. Support for the use of this flag can be queried from the
      device attribute cudaDeviceAttrReadOnlyHostRegisterSupported. Using
      this flag with a current context associated with a device that does
      not have this attribute set will cause :py:obj:`~.cudaHostRegister`
      to error with cudaErrorNotSupported.

    All of these flags are orthogonal to one another: a developer may page-
    lock memory that is portable or mapped with no restrictions.

    The CUDA context must have been created with the
    :py:obj:`~.cudaMapHost` flag in order for the
    :py:obj:`~.cudaHostRegisterMapped` flag to have any effect.

    The :py:obj:`~.cudaHostRegisterMapped` flag may be specified on CUDA
    contexts for devices that do not support mapped pinned memory. The
    failure is deferred to :py:obj:`~.cudaHostGetDevicePointer()` because
    the memory may be mapped into other CUDA contexts via the
    :py:obj:`~.cudaHostRegisterPortable` flag.

    For devices that have a non-zero value for the device attribute
    :py:obj:`~.cudaDevAttrCanUseHostPointerForRegisteredMem`, the memory
    can also be accessed from the device using the host pointer `ptr`. The
    device pointer returned by :py:obj:`~.cudaHostGetDevicePointer()` may
    or may not match the original host pointer `ptr` and depends on the
    devices visible to the application. If all devices visible to the
    application have a non-zero value for the device attribute, the device
    pointer returned by :py:obj:`~.cudaHostGetDevicePointer()` will match
    the original pointer `ptr`. If any device visible to the application
    has a zero value for the device attribute, the device pointer returned
    by :py:obj:`~.cudaHostGetDevicePointer()` will not match the original
    host pointer `ptr`, but it will be suitable for use on all devices
    provided Unified Virtual Addressing is enabled. In such systems, it is
    valid to access the memory using either pointer on devices that have a
    non-zero value for the device attribute. Note however that such devices
    should access the memory using only of the two pointers and not both.

    The memory page-locked by this function must be unregistered with
    :py:obj:`~.cudaHostUnregister()`.

    Parameters
    ----------
    ptr : Any

    be present on the host, :py:obj:`~.cudaMemcpy3D()` will disregard that
    implication and silently correct the kind based on the fact that
    cudaArray type can only be present on the device.

    If the source and destination are both arrays,
    :py:obj:`~.cudaMemcpy3D()` will return an error if they do not have the
    same element size.

    The source and destination object may not overlap. If overlapping
    source and destination objects are specified, undefined behavior will
    result.

    The source object must entirely contain the region defined by `srcPos`
    and `extent`. The destination object must entirely contain the region
    defined by `dstPos` and `extent`.

    :py:obj:`~.cudaMemcpy3D()` returns an error if the pitch of `srcPtr` or

    :py:obj:`~.cudaMemcpy3DAsync()` copies data betwen two 3D objects. The
    source and destination objects may be in either host memory, device
    memory, or a CUDA array. The source, destination, extent, and kind of
    copy performed is specified by the :py:obj:`~.cudaMemcpy3DParms` struct
    which should be initialized to zero before use:

    **View CUDA Toolkit Documentation for a C++ code example**

    The struct passed to :py:obj:`~.cudaMemcpy3DAsync()` must specify one

    more than one non-zero source or destination will cause
    :py:obj:`~.cudaMemcpy3DAsync()` to return an error.

    The `srcPos` and `dstPos` fields are optional offsets into the source
    and destination objects and are defined in units of each object's
    elements. The element for a host or device pointer is assumed to be
    unsigned char. For CUDA arrays, positions must be in the range [0,
    2048) for any dimension.

    The `extent` field defines the dimensions of the transferred area in
    elements. If a CUDA array is participating in the copy, the extent is
    defined in terms of that array's elements. If no CUDA array is
    participating in the copy then the extents are defined in elements of
    unsigned char.

    The `kind` field defines the direction of the copy. It must be one of

    :py:obj:`~.cudaMemcpy3DAsync()` is asynchronous with respect to the

    optionally be associated to a stream by passing a non-zero `stream`
    argument. If `kind` is :py:obj:`~.cudaMemcpyHostToDevice` or
    :py:obj:`~.cudaMemcpyDeviceToHost` and `stream` is non-zero, the copy

    """ Prefetches memory to the specified destination device.

    Prefetches memory to the specified destination device. `devPtr` is the
    base device pointer of the memory to be prefetched and `dstDevice` is
    the destination device. `count` specifies the number of bytes to copy.
    `stream` is the stream in which the operation is enqueued. The memory
    range must refer to managed memory allocated via
    :py:obj:`~.cudaMallocManaged` or declared via managed variables.

    Passing in cudaCpuDeviceId for `dstDevice` will prefetch the data to
    host memory. If `dstDevice` is a GPU, then the device attribute
    :py:obj:`~.cudaDevAttrConcurrentManagedAccess` must be non-zero.
    Additionally, `stream` must be associated with a device that has a non-
    zero value for the device attribute
    :py:obj:`~.cudaDevAttrConcurrentManagedAccess`.

    The start address and end address of the memory range will be rounded
    down and rounded up respectively to be aligned to CPU page size before
    the prefetch operation is enqueued in the stream.

    If no physical memory has been allocated for this region, then this
    memory region will be populated and mapped on the destination device.
    If there's insufficient memory to prefetch the desired region, the
    Unified Memory driver may evict pages from other
    :py:obj:`~.cudaMallocManaged` allocations to host memory in order to
    make room. Device memory allocated using :py:obj:`~.cudaMalloc` or
    :py:obj:`~.cudaMallocArray` will not be evicted.

    By default, any mappings to the previous location of the migrated pages
    are removed and mappings for the new location are only setup on
    `dstDevice`. The exact behavior however also depends on the settings
    applied to this memory range via :py:obj:`~.cudaMemAdvise` as described
    below:

    If :py:obj:`~.cudaMemAdviseSetReadMostly` was set on any subset of this
    memory range, then that subset will create a read-only copy of the
    pages on `dstDevice`.

    If :py:obj:`~.cudaMemAdviseSetPreferredLocation` was called on any
    subset of this memory range, then the pages will be migrated to
    `dstDevice` even if `dstDevice` is not the preferred location of any
    pages in the memory range.

    If :py:obj:`~.cudaMemAdviseSetAccessedBy` was called on any subset of
    this memory range, then mappings to those pages from all the
    appropriate processors are updated to refer to the new location if
    establishing such a mapping is possible. Otherwise, those mappings are
    cleared.

    Note that this API is not required for functionality and only serves to
    improve performance by allowing the application to migrate data to a
    suitable location before it is accessed. Memory accesses to this range
    are always coherent and are allowed even when the data is actively
    being migrated.

    Note that this function is asynchronous with respect to the host and
    all work on other devices.

def cudaMemAdvise(devPtr, size_t count, advice not None : cudaMemoryAdvise, int device):
    """ Advise about the usage of a given memory range.

    Advise the Unified Memory subsystem about the usage pattern for the
    memory range starting at `devPtr` with a size of `count` bytes. The
    start address and end address of the memory range will be rounded down
    and rounded up respectively to be aligned to CPU page size before the
    advice is applied. The memory range must refer to managed memory
    allocated via :py:obj:`~.cudaMallocManaged` or declared via managed
    variables. The memory range could also refer to system-allocated
    pageable memory provided it represents a valid, host-accessible region
    of memory and all additional constraints imposed by `advice` as
    outlined below are also satisfied. Specifying an invalid system-
    allocated pageable memory range results in an error being returned.

    The `advice` parameter can take the following values:

    - :py:obj:`~.cudaMemAdviseSetReadMostly`: This implies that the data is
      mostly going to be read from and only occasionally written to. Any
      read accesses from any processor to this region will create a read-
      only copy of at least the accessed pages in that processor's memory.
      Additionally, if :py:obj:`~.cudaMemPrefetchAsync` is called on this
      region, it will create a read-only copy of the data on the
      destination processor. If any processor writes to this region, all
      copies of the corresponding page will be invalidated except for the
      one where the write occurred. The `device` argument is ignored for
      this advice. Note that for a page to be read-duplicated, the
      accessing processor must either be the CPU or a GPU that has a non-
      zero value for the device attribute
      :py:obj:`~.cudaDevAttrConcurrentManagedAccess`. Also, if a context is
      created on a device that does not have the device attribute
      :py:obj:`~.cudaDevAttrConcurrentManagedAccess` set, then read-
      duplication will not occur until all such contexts are destroyed. If
      the memory region refers to valid system-allocated pageable memory,
      then the accessing device must have a non-zero value for the device
      attribute :py:obj:`~.cudaDevAttrPageableMemoryAccess` for a read-only
      copy to be created on that device. Note however that if the accessing
      device also has a non-zero value for the device attribute
      :py:obj:`~.cudaDevAttrPageableMemoryAccessUsesHostPageTables`, then
      setting this advice will not create a read-only copy when that device
      accesses this memory region.

    - :py:obj:`~.cudaMemAdviceUnsetReadMostly`: Undoes the effect of
      :py:obj:`~.cudaMemAdviceReadMostly` and also prevents the Unified
      Memory driver from attempting heuristic read-duplication on the
      memory range. Any read-duplicated copies of the data will be
      collapsed into a single copy. The location for the collapsed copy
      will be the preferred location if the page has a preferred location
      and one of the read-duplicated copies was resident at that location.
      Otherwise, the location chosen is arbitrary.

    - :py:obj:`~.cudaMemAdviseSetPreferredLocation`: This advice sets the
      preferred location for the data to be the memory belonging to
      `device`. Passing in cudaCpuDeviceId for `device` sets the preferred
      location as host memory. If `device` is a GPU, then it must have a
      non-zero value for the device attribute
      :py:obj:`~.cudaDevAttrConcurrentManagedAccess`. Setting the preferred
      location does not cause data to migrate to that location immediately.
      Instead, it guides the migration policy when a fault occurs on that
      memory region. If the data is already in its preferred location and
      the faulting processor can establish a mapping without requiring the
      data to be migrated, then data migration will be avoided. On the
      other hand, if the data is not in its preferred location or if a
      direct mapping cannot be established, then it will be migrated to the
      processor accessing it. It is important to note that setting the
      preferred location does not prevent data prefetching done using
      :py:obj:`~.cudaMemPrefetchAsync`. Having a preferred location can
      override the page thrash detection and resolution logic in the
      Unified Memory driver. Normally, if a page is detected to be
      constantly thrashing between for example host and device memory, the
      page may eventually be pinned to host memory by the Unified Memory
      driver. But if the preferred location is set as device memory, then
      the page will continue to thrash indefinitely. If
      :py:obj:`~.cudaMemAdviseSetReadMostly` is also set on this memory
      region or any subset of it, then the policies associated with that
      advice will override the policies of this advice, unless read
      accesses from `device` will not result in a read-only copy being
      created on that device as outlined in description for the advice
      :py:obj:`~.cudaMemAdviseSetReadMostly`. If the memory region refers
      to valid system-allocated pageable memory, then `device` must have a
      non-zero value for the device attribute
      :py:obj:`~.cudaDevAttrPageableMemoryAccess`. Additionally, if
      `device` has a non-zero value for the device attribute
      :py:obj:`~.cudaDevAttrPageableMemoryAccessUsesHostPageTables`, then
      this call has no effect. Note however that this behavior may change
      in the future.

    - :py:obj:`~.cudaMemAdviseUnsetPreferredLocation`: Undoes the effect of
      :py:obj:`~.cudaMemAdviseSetPreferredLocation` and changes the
      preferred location to none.

    - :py:obj:`~.cudaMemAdviseSetAccessedBy`: This advice implies that the
      data will be accessed by `device`. Passing in
      :py:obj:`~.cudaCpuDeviceId` for `device` will set the advice for the
      CPU. If `device` is a GPU, then the device attribute
      :py:obj:`~.cudaDevAttrConcurrentManagedAccess` must be non-zero. This
      advice does not cause data migration and has no impact on the
      location of the data per se. Instead, it causes the data to always be
      mapped in the specified processor's page tables, as long as the
      location of the data permits a mapping to be established. If the data
      gets migrated for any reason, the mappings are updated accordingly.
      This advice is recommended in scenarios where data locality is not
      important, but avoiding faults is. Consider for example a system
      containing multiple GPUs with peer-to-peer access enabled, where the
      data located on one GPU is occasionally accessed by peer GPUs. In
      such scenarios, migrating data over to the other GPUs is not as
      important because the accesses are infrequent and the overhead of
      migration may be too high. But preventing faults can still help
      improve performance, and so having a mapping set up in advance is
      useful. Note that on CPU access of this data, the data may be
      migrated to host memory because the CPU typically cannot access
      device memory directly. Any GPU that had the
      :py:obj:`~.cudaMemAdviceSetAccessedBy` flag set for this data will
      now have its mapping updated to point to the page in host memory. If
      :py:obj:`~.cudaMemAdviseSetReadMostly` is also set on this memory
      region or any subset of it, then the policies associated with that
      advice will override the policies of this advice. Additionally, if
      the preferred location of this memory region or any subset of it is
      also `device`, then the policies associated with
      :py:obj:`~.cudaMemAdviseSetPreferredLocation` will override the
      policies of this advice. If the memory region refers to valid system-
      allocated pageable memory, then `device` must have a non-zero value
      for the device attribute :py:obj:`~.cudaDevAttrPageableMemoryAccess`.
      Additionally, if `device` has a non-zero value for the device
      attribute
      :py:obj:`~.cudaDevAttrPageableMemoryAccessUsesHostPageTables`, then
      this call has no effect.

    - :py:obj:`~.cudaMemAdviseUnsetAccessedBy`: Undoes the effect of
      :py:obj:`~.cudaMemAdviseSetAccessedBy`. Any mappings to the data from
      `device` may be removed at any time causing accesses to result in
      non-fatal page faults. If the memory region refers to valid system-
      allocated pageable memory, then `device` must have a non-zero value
      for the device attribute :py:obj:`~.cudaDevAttrPageableMemoryAccess`.
      Additionally, if `device` has a non-zero value for the device
      attribute
      :py:obj:`~.cudaDevAttrPageableMemoryAccessUsesHostPageTables`, then
      this call has no effect.

    The `attribute` parameter can take the following values:

    - :py:obj:`~.cudaMemRangeAttributeReadMostly`: If this attribute is

      `dataSize` must be 4. The result returned will be 1 if all pages in

    - :py:obj:`~.cudaMemRangeAttributePreferredLocation`: If this attribute
      is specified, `data` will be interpreted as a 32-bit integer, and
      `dataSize` must be 4. The result returned will be a GPU device id if
      all pages in the memory range have that GPU as their preferred
      location, or it will be cudaCpuDeviceId if all pages in the memory

      location at all. Note that the actual location of the pages in the
      memory range at the time of the query may be different from the
      preferred location.

    - :py:obj:`~.cudaMemRangeAttributeAccessedBy`: If this attribute is
      specified, `data` will be interpreted as an array of 32-bit integers,
      and `dataSize` must be a non-zero multiple of 4. The result returned
      will be a list of device ids that had
      :py:obj:`~.cudaMemAdviceSetAccessedBy` set for that entire memory

      than the number of devices that have that advice set for that memory
      range, cudaInvalidDeviceId will be returned in all the extra space
      provided. For ex., if `dataSize` is 12 (i.e. `data` has 3 elements)
      and only device 0 has the advice set, then the result returned will
      be { 0, cudaInvalidDeviceId, cudaInvalidDeviceId }. If `data` is
      smaller than the number of devices that have that advice set, then
      only as many devices will be returned as can fit in the array. There
      is no guarantee on which specific devices will be returned, however.

    - :py:obj:`~.cudaMemRangeAttributeLastPrefetchLocation`: If this
      attribute is specified, `data` will be interpreted as a 32-bit
      integer, and `dataSize` must be 4. The result returned will be the
      last location to which all pages in the memory range were prefetched
      explicitly via :py:obj:`~.cudaMemPrefetchAsync`. This will either be
      a GPU id or cudaCpuDeviceId depending on whether the last location
      for prefetch was a GPU or the CPU respectively. If any page in the

      prefetched to the same location, cudaInvalidDeviceId will be
      returned. Note that this simply returns the last location that the

    Notes
    -----
    The default memory pool of a device contains device memory from that device.

    Basic stream ordering allows future work submitted into the same stream to use the allocation. Stream query, stream synchronize, and CUDA events can be used to guarantee that the allocation operation completes before work submitted in a separate stream runs.

    During stream capture, this function results in the creation of an allocation node. In this case, the allocation is owned by the graph instead of the memory pool. The memory pool's properties are used to set the node's creation parameters.

    The :py:obj:`~.cudaPointerAttributes` structure is defined as:

    In this structure, the individual fields mean

    - :py:obj:`~.cudaPointerAttributes.type` identifies type of memory. It
      can be :py:obj:`~.cudaMemoryTypeUnregistered` for unregistered host
      memory, :py:obj:`~.cudaMemoryTypeHost` for registered host memory,
      :py:obj:`~.cudaMemoryTypeDevice` for device memory or
      :py:obj:`~.cudaMemoryTypeManaged` for managed memory.

    - :py:obj:`~.device` is the device against which `ptr` was allocated.
      If `ptr` has memory type :py:obj:`~.cudaMemoryTypeDevice` then this
      identifies the device on which the memory referred to by `ptr`
      physically resides. If `ptr` has memory type
      :py:obj:`~.cudaMemoryTypeHost` then this identifies the device which
      was current when the allocation was made (and if that device is
      deinitialized then this allocation will vanish with that device's
      state).

    - :py:obj:`~.devicePointer` is the device pointer alias through which
      the memory referred to by `ptr` may be accessed on the current
      device. If the memory referred to by `ptr` cannot be accessed
      directly by the current device then this is NULL.

    - :py:obj:`~.hostPointer` is the host pointer alias through which the
      memory referred to by `ptr` may be accessed on the host. If the

      whether the trilinear filtering optimizations will be disabled.

    - :py:obj:`~.cudaTextureDesc_v2.seamlessCubemap` specifies whether
      seamless cube map filtering is enabled. This flag can only be
      specified if the underlying resource is a CUDA array or a CUDA
      mipmapped array that was created with the flag
      :py:obj:`~.cudaArrayCubemap`. When seamless cube map filtering is
      enabled, texture address modes specified by
      :py:obj:`~.cudaTextureDesc_v2.addressMode` are ignored. Instead, if
      the :py:obj:`~.cudaTextureDesc_v2.filterMode` is set to
      :py:obj:`~.cudaFilterModePoint` the address mode
      :py:obj:`~.cudaAddressModeClamp` will be applied for all dimensions.
      If the :py:obj:`~.cudaTextureDesc_v2.filterMode` is set to
      :py:obj:`~.cudaFilterModeLinear` seamless cube map filtering will be
      performed when sampling along the cube face borders.

    The :py:obj:`~.cudaResourceViewDesc` struct is defined as

    **View CUDA Toolkit Documentation for a C++ code example**

    where:

    - :py:obj:`~.cudaResourceViewDesc.format` specifies how the data
      contained in the CUDA array or CUDA mipmapped array should be
      interpreted. Note that this can incur a change in size of the texture
      data. If the resource view format is a block compressed format, then
      the underlying CUDA array or CUDA mipmapped array has to have a
      32-bit unsigned integer format with 2 or 4 channels, depending on the
      block compressed format. For ex., BC1 and BC4 require the underlying
      CUDA array to have a 32-bit unsigned int with 2 channels. The other
      BC formats require the underlying resource to have the same 32-bit
      unsigned int format but with 4 channels.

    - :py:obj:`~.cudaResourceViewDesc.width` specifies the new width of the
      texture data. If the resource view format is a block compressed
      format, this value has to be 4 times the original width of the
      resource. For non block compressed formats, this value has to be
      equal to that of the original resource.

    - :py:obj:`~.cudaResourceViewDesc.height` specifies the new height of
      the texture data. If the resource view format is a block compressed
      format, this value has to be 4 times the original height of the
      resource. For non block compressed formats, this value has to be
      equal to that of the original resource.

    - :py:obj:`~.cudaResourceViewDesc.depth` specifies the new depth of the
      texture data. This value has to be equal to that of the original
      resource.

    - :py:obj:`~.cudaResourceViewDesc.firstMipmapLevel` specifies the most
      detailed mipmap level. This will be the new mipmap level zero. For
      non-mipmapped resources, this value has to be
      zero.:py:obj:`~.cudaTextureDesc_v2.minMipmapLevelClamp` and
      :py:obj:`~.cudaTextureDesc_v2.maxMipmapLevelClamp` will be relative
      to this value. For ex., if the firstMipmapLevel is set to 2, and a
      minMipmapLevelClamp of 1.2 is specified, then the actual minimum
      mipmap level clamp will be 3.2.

    - :py:obj:`~.cudaResourceViewDesc.lastMipmapLevel` specifies the least
      detailed mipmap level. For non-mipmapped resources, this value has to
      be zero.

    - :py:obj:`~.cudaResourceViewDesc.firstLayer` specifies the first layer
      index for layered textures. This will be the new layer zero. For non-
      layered resources, this value has to be zero.

    - :py:obj:`~.cudaResourceViewDesc.lastLayer` specifies the last layer
      index for layered textures. For non-layered resources, this value has
      to be zero.

    Creates a new kernel execution node and adds it to `graph` with
    `numDependencies` dependencies specified via `pDependencies` and
    arguments specified in `pNodeParams`. It is possible for
    `numDependencies` to be 0, in which case the node will be placed at the
    root of the graph. `pDependencies` may not have any duplicate entries.
    A handle to the new node will be returned in `pGraphNode`.

    The :py:obj:`~.cudaKernelNodeParams` structure is defined as:

    **View CUDA Toolkit Documentation for a C++ code example**

    When the graph is launched, the node will invoke kernel `func` on a
    (`gridDim.x` x `gridDim.y` x `gridDim.z`) grid of blocks. Each block
    contains (`blockDim.x` x `blockDim.y` x `blockDim.z`) threads.

    `sharedMem` sets the amount of dynamic shared memory that will be
    available to each thread block.

    Kernel parameters to `func` can be specified in one of two ways:

    1) Kernel parameters can be specified via `kernelParams`. If the kernel
    has N parameters, then `kernelParams` needs to be an array of N
    pointers. Each pointer, from `kernelParams`[0] to `kernelParams`[N-1],
    points to the region of memory from which the actual parameter will be
    copied. The number of kernel parameters and their offsets and sizes do
    not need to be specified as that information is retrieved directly from
    the kernel's image.

    2) Kernel parameters can also be packaged by the application into a
    single buffer that is passed in via `extra`. This places the burden on
    the application of knowing each kernel parameter's size and
    alignment/padding within the buffer. The `extra` parameter exists to
    allow this function to take additional less commonly used arguments.
    `extra` specifies a list of names of extra settings and their
    corresponding values. Each extra setting name is immediately followed
    by the corresponding value. The list must be terminated with either
    NULL or CU_LAUNCH_PARAM_END.

    - :py:obj:`~.CU_LAUNCH_PARAM_END`, which indicates the end of the
      `extra` array;

    - :py:obj:`~.CU_LAUNCH_PARAM_BUFFER_POINTER`, which specifies that the
      next value in `extra` will be a pointer to a buffer containing all
      the kernel parameters for launching kernel `func`;

    - :py:obj:`~.CU_LAUNCH_PARAM_BUFFER_SIZE`, which specifies that the
      next value in `extra` will be a pointer to a size_t containing the
      size of the buffer specified with
      :py:obj:`~.CU_LAUNCH_PARAM_BUFFER_POINTER`;

    The error :py:obj:`~.cudaErrorInvalidValue` will be returned if kernel
    parameters are specified with both `kernelParams` and `extra` (i.e.
    both `kernelParams` and `extra` are non-NULL).

    The `kernelParams` or `extra` array, as well as the argument values it
    points to, are copied during this call.

    Parameters
    ----------
    graph : :py:obj:`~.CUgraph` or :py:obj:`~.cudaGraph_t`
        Graph to which to add the node
    pDependencies : List[:py:obj:`~.cudaGraphNode_t`]

    Creates a new allocation node and adds it to `graph` with

    `numDependencies` to be 0, in which case the node will be placed at the
    root of the graph. `pDependencies` may not have any duplicate entries.
    A handle to the new node will be returned in `pGraphNode`.

    When :py:obj:`~.cudaGraphAddMemAllocNode` creates an allocation node,
    it returns the address of the allocation in `nodeParams.dptr`. The
    allocation's address remains fixed across instantiations and launches.

    If the allocation is freed in the same graph, by creating a free node
    using :py:obj:`~.cudaGraphAddMemFreeNode`, the allocation can be
    accessed by nodes ordered after the allocation node but before the free
    node. These allocations cannot be freed outside the owning graph, and
    they can only be freed once in the owning graph.

    If the allocation is not freed in the same graph, then it can be
    accessed not only by nodes in the graph which are ordered after the
    allocation node, but also by stream operations ordered after the
    graph's execution but before the allocation is freed.

    Allocations which are not freed in the same graph can be freed by:

    - passing the allocation to :py:obj:`~.cudaMemFreeAsync` or
      :py:obj:`~.cudaMemFree`;

    - launching a graph with a free node for that allocation; or

    - specifying :py:obj:`~.cudaGraphInstantiateFlagAutoFreeOnLaunch`
      during instantiation, which makes each launch behave as though it
      called :py:obj:`~.cudaMemFreeAsync` for every unfreed allocation.

    It is not possible to free an allocation in both the owning graph and
    another graph. If the allocation is freed in the same graph, a free
    node cannot be added to another graph. If the allocation is freed in
    another graph, a free node can no longer be added to the owning graph.

    The following restrictions apply to graphs which contain allocation
    and/or memory free nodes:

    - Nodes and edges of the graph cannot be deleted.

    - The graph cannot be used in a child node.

    - Only one instantiation of the graph may exist at any point in time.

    - The graph cannot be cloned.

    Parameters
    ----------
    graph : :py:obj:`~.CUgraph` or :py:obj:`~.cudaGraph_t`
        Graph to which to add the node
    pDependencies : List[:py:obj:`~.cudaGraphNode_t`]

    The `flags` parameter controls the behavior of instantiation and

    - :py:obj:`~.cudaGraphInstantiateFlagUseNodePriority`, which causes the
      graph to use the priorities from the per-node attributes rather than
      the priority of the launch stream during execution. Note that
      priorities are only available on kernel nodes, and are copied from
      stream priority during stream capture.

    If `graph` contains any allocation or free nodes, there can be at most
    one executable graph in existence for that graph at a time.

    An attempt to instantiate a second executable graph before destroying

    Updates the node parameters in the instantiated graph specified by
    `hGraphExec` with the node parameters in a topologically identical
    graph specified by `hGraph`.

    Limitations:

    - Kernel nodes:

      - The owning context of the function cannot change.

      - A node whose function originally did not use CUDA dynamic
        parallelism cannot be updated to a function which uses CDP.

      - A cooperative node cannot be updated to a non-cooperative node, and
        vice-versa.

      - If the graph was instantiated with
        cudaGraphInstantiateFlagUseNodePriority, the priority attribute
        cannot change. Equality is checked on the originally requested
        priority values, before they are clamped to the device's supported
        range.

    - Memset and memcpy nodes:

      - The CUDA device(s) to which the operand(s) was allocated/mapped
        cannot change.

      - The source/destination memory must be allocated from the same
        contexts as the original source/destination memory.

      - Only 1D memsets can be changed.

    - Additional memcpy node restrictions:

      - Changing either the source or destination memory type(i.e.
        CU_MEMORYTYPE_DEVICE, CU_MEMORYTYPE_ARRAY, etc.) is not supported.

    Note: The API may add further restrictions in future releases. The
    return code should always be checked.

    cudaGraphExecUpdate sets `updateResult_out` to
    cudaGraphExecUpdateErrorTopologyChanged under the following conditions:

    - The count of nodes directly in `hGraphExec` and `hGraph` differ, in
      which case `hErrorNode_out` is NULL.

    - A node is deleted in `hGraph` but not not its pair from `hGraphExec`,
      in which case `hErrorNode_out` is NULL.

    - A node is deleted in `hGraphExec` but not its pair from `hGraph`, in
      which case `hErrorNode_out` is the pairless node from `hGraph`.

    - The dependent nodes of a pair differ, in which case `hErrorNode_out`
      is the node from `hGraph`.

    cudaGraphExecUpdate sets `updateResult_out` to:

    - cudaGraphExecUpdateError if passed an invalid value.

    - cudaGraphExecUpdateErrorTopologyChanged if the graph topology changed

    - cudaGraphExecUpdateErrorNodeTypeChanged if the type of a node
      changed, in which case `hErrorNode_out` is set to the node from
      `hGraph`.

    - cudaGraphExecUpdateErrorFunctionChanged if the function of a kernel
      node changed (CUDA driver < 11.2)

    - cudaGraphExecUpdateErrorUnsupportedFunctionChange if the func field
      of a kernel changed in an unsupported way(see note above), in which
      case `hErrorNode_out` is set to the node from `hGraph`

    - cudaGraphExecUpdateErrorParametersChanged if any parameters to a node
      changed in a way that is not supported, in which case
      `hErrorNode_out` is set to the node from `hGraph`

    - cudaGraphExecUpdateErrorAttributesChanged if any attributes of a node
      changed in a way that is not supported, in which case
      `hErrorNode_out` is set to the node from `hGraph`

    - cudaGraphExecUpdateErrorNotSupported if something about a node is
      unsupported, like the node's type or configuration, in which case
      `hErrorNode_out` is set to the node from `hGraph`

    If `updateResult_out` isn't set in one of the situations described
    above, the update check passes and cudaGraphExecUpdate updates
    `hGraphExec` to match the contents of `hGraph`. If an error happens
    during the update, `updateResult_out` will be set to
    cudaGraphExecUpdateError; otherwise, `updateResult_out` is set to
    cudaGraphExecUpdateSuccess.

    cudaGraphExecUpdate returns cudaSuccess when the updated was performed
    successfully. It returns cudaErrorGraphExecUpdateFailure if the graph
    update was not performed because it included changes which violated
    constraints specific to instantiated graph update.

    Parameters
    ----------
    hGraphExec : :py:obj:`~.CUgraphExec` or :py:obj:`~.cudaGraphExec_t`
        The instantiated graph to be updated
    hGraph : :py:obj:`~.CUgraph` or :py:obj:`~.cudaGraph_t`

def cudaGetDriverEntryPoint(char* symbol, unsigned long long flags):
    """ Returns the requested driver API function pointer.

    Returns in `**funcPtr` the address of the CUDA driver function for the
    requested flags.

    For a requested driver symbol, if the CUDA version in which the driver
    symbol was introduced is less than or equal to the CUDA runtime
    version, the API will return the function pointer to the corresponding
    versioned driver function.

    The pointer returned by the API should be cast to a function pointer
    matching the requested driver function's definition in the API header
    file. The function pointer typedef can be picked up from the
    corresponding typedefs header file. For example, cudaTypedefs.h
    consists of function pointer typedefs for driver APIs defined in
    cuda.h.

    The API will return :py:obj:`~.cudaErrorSymbolNotFound` if the
    requested driver function is not supported on the platform, no ABI
    compatible driver function exists for the CUDA runtime version or if
    the driver symbol is invalid.

    The requested flags can be:

    - :py:obj:`~.cudaEnableDefault`: This is the default mode. This is
      equivalent to :py:obj:`~.cudaEnablePerThreadDefaultStream` if the
      code is compiled with --default-stream per-thread compilation flag or
      the macro CUDA_API_PER_THREAD_DEFAULT_STREAM is defined;
      :py:obj:`~.cudaEnableLegacyStream` otherwise.

    - :py:obj:`~.cudaEnableLegacyStream`: This will enable the search for
      all driver symbols that match the requested driver symbol name except
      the corresponding per-thread versions.

    - :py:obj:`~.cudaEnablePerThreadDefaultStream`: This will enable the
      search for all driver symbols that match the requested driver symbol
      name including the per-thread versions. If a per-thread version is
      not found, the API will return the legacy version of the driver
      function.

    Parameters
    ----------
    symbol : bytes
        The base name of the driver API function to look for. As an
        example, for the driver API :py:obj:`~.cuMemAlloc_v2`, `symbol`
        would be cuMemAlloc. Note that the API will use the CUDA runtime
        version to return the address to the most recent ABI compatible
        driver symbol, :py:obj:`~.cuMemAlloc` or :py:obj:`~.cuMemAlloc_v2`.
    flags : unsigned long long

    Using this API user can initialize the CUDA profiler by specifying the

    counters.

    Limitation: The CUDA profiler cannot be initialized with this API if
    another profiling tool is already active, as indicated by the
    :py:obj:`~.cudaErrorProfilerDisabled` return code.

    Typical usage of the profiling APIs is as follows:

    for each set of counters/options {

    counters/options in the config file   ...

    // code to be profiled   :py:obj:`~.cudaProfilerStop()`;  ... }

    Parameters
    ----------
    configFile : bytes
        Name of the config file that lists the counters/options for

    Additional Mapping/Unmapping is not required for the registered
    resource and :py:obj:`~.cudaGraphicsResourceGetMappedEglFrame` can be

    The application will be responsible for synchronizing access to shared

    may be accomplished by issuing and waiting for glFinish command on all

    registered CUDA resource has completed prior to executing subsequent
    commands in other APIs accesing the same memory objects. This can be
    accomplished by calling cuCtxSynchronize or cuEventSynchronize
    (preferably).

    The surface's intended usage is specified using `flags`, as follows:

    - :py:obj:`~.cudaGraphicsRegisterFlagsNone`: Specifies no hints about
      how this resource will be used. It is therefore assumed that this
      resource will be read from and written to by CUDA. This is the
      default value.

    - :py:obj:`~.cudaGraphicsRegisterFlagsReadOnly`: Specifies that CUDA
      will not write to this resource.

    - :py:obj:`~.cudaGraphicsRegisterFlagsWriteDiscard`: Specifies that
      CUDA will not read from this resource and will write over the entire
      contents of the resource, so none of the data previously stored in
      the resource will be preserved.
