## Detailed Description

This activity record represents execution for a graph without giving visibility about the execution of its nodes. This is intended to reduce overheads in tracing each node. The activity kind is CUPTI_ACTIVITY_KIND_GRAPH_TRACE

## Field Documentation

uint32_t CUpti_ActivityGraphTrace::contextId

The ID of the context where the graph is being launched.

uint32_t CUpti_ActivityGraphTrace::correlationId

The correlation ID of the graph launch. Each graph launch is assigned a unique correlation ID that is identical to the correlation ID in the driver API activity record that launched the graph.

uint32_t CUpti_ActivityGraphTrace::deviceId

The ID of the device where the graph execution is occurring.

uint64_t CUpti_ActivityGraphTrace::end

The end timestamp for the graph execution, in ns. A value of 0 for both the start and end timestamps indicates that timestamp information could not be collected for the graph.

uint32_t CUpti_ActivityGraphTrace::graphId

The unique ID of the graph that is launched.

CUpti_ActivityKind CUpti_ActivityGraphTrace::kind

The activity record kind, must be CUPTI_ACTIVITY_KIND_GRAPH_TRACE

void* CUpti_ActivityGraphTrace::reserved

This field is reserved for internal use

uint64_t CUpti_ActivityGraphTrace::start

The start timestamp for the graph execution, in ns. A value of 0 for both the start and end timestamps indicates that timestamp information could not be collected for the graph.

uint32_t CUpti_ActivityGraphTrace::streamId

The ID of the stream where the graph is being launched.
