Support for Parallel Computation


Support for parallel computation, including random-number generation.


This package is under development: a first version was released with R 2.14.0.

There is support for multiple RNG streams with the "L'Ecuyer-CMRG" RNG: see nextRNGStream.

It contains functionality derived from and pretty much equivalent to that contained in packages \CRANpkgmulticore (with some low-level functions renamed and not exported) and \CRANpkgsnow (for socket clusters only, but MPI and NWS clusters generated by \CRANpkgsnow are also supported). This package also provides makeForkCluster.

For a complete list of exported functions, use library(help = "parallel").

Parallel computation involves launching worker processes: functions psnice and pskill in package tools provide means to manage such processes.
