parallelMap 1.5.1

• Removed “LazyDate” field from DESCRIPTION.
• Fixed broken URLs.

parallelMap 1.5.0

• parallelLapply() does not drop list element names anymore (#58)

• parallelStart() gains argument reproducible. This argument ensures reproducibility across parallel workers and is set to TRUE by default. Internally, we take care to use the "L'Ecuyer-CMRG" RNG kind or clusterSetRNGStream() (depending on the parallel mode) to ensure this. This argument works similar to the future.seed argument for future-based parallelization which also ensures reproducibility across parallel processes with the standard RNG kind.

• parallelLibrary(): Respect custom levels when exporting packages (#67)

• parallelLibrary(): Allow to add packages to a batchtools library (@dagola, #70)

• Bugfix: Printing the state of an object holding the current parallelMap options (queried via parallelGetOptions()) did not return the object state but instead the global state of the options (#41, @mb706).

parallelMap 1.4

• Load balancing for multicore, socket and mpi can now be controlled via the flag “load.balancing” passed to parallelStart(). Note that the default for multicore now defaults to disabled load balancing.
• BatchTools mode

parallelMap 1.3

• parallelGetRegisteredLevels has new argument “flatten”
• parallelShowOptions was converted to parallelGetOptions (with a printer)

parallelMap 1.2

• Arguments of mcmapply (mc.preschedule, …) can now be specified via parallelStart
• We import package “parallel” now
• parallelShowRegisteredLevels was changed to parallelGetRegisteredLevels. The latter returns a structured object, with a printer method.

parallelMap 1.1

• Package in general much more stable now
• parallelLibrary was improved a lot
• better / more configurable info messages on console
• BatchJobs mode: working directory for slave jobs is the current working dir on the master, not the storage.dir
• BatchJobs mode: errors are thrown, if jobs expire
• parallelMap/Lapply/Sapply: impute.error option
• removed autostart option for stability

new functions

• parallelSource
• parallelExport
