The doParallel Package
Description
The doParallel package provides a parallel backend for the foreach/%dopar%
function using the parallel package of R 2.14.0 and later.
Details
Further information is available in the following help topics:
registerDoParallel | register doParallel to be used by foreach/%dopar% |
To see a tutorial introduction to the doParallel package,
use vignette("gettingstartedParallel"). To see a tutorial
introduction to the foreach package, use vignette("foreach").
To see a demo of doParallel computing the sinc function,
use demo(sincParallel).
Some examples (in addition to those in the help pages) are included in
the “examples” directory of the doParallel package. To list the files in
the examples directory,
use list.files(system.file("examples", package="doParallel")).
To run the bootstrap example, use
source(system.file("examples", "bootParallel.R", package="doParallel")).
This is a simple benchmark, executing both sequentally and in parallel.
There are many more examples that come with the foreach package,
which will work with the doParallel package if it is registered as the
parallel backend.
For a complete list of functions with individual help pages,
use library(help="doParallel").
