Support for Parallel Computation

Description

Support for parallel computation, including random-number generation.

Details

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 multicore (with some low-level functions renamed and not exported) and snow (for socket clusters only, but MPI, NWS and PVM clusters generated by snow 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.
