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

parallelMap 1.0-83

• First submit to CRAN.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
