Setup parallel processing

Sets up parallel processing using the snowfall package

Usage

setup(cpus = NULL, logical = FALSE, ...)

Arguments

cpus

the number of CPUs to use for parallel processing. If left empty all physical cores will be used, unless logical=TRUE, in which case both physical and logical (virtual) cores will be used.

logical

Use the logical cores as well? Using the virtual cores may not lead to any significant decrease in run time. You can test the optimal number of cores using optCPU()

Examples

if (FALSE) { # \dontrun{
setup() # set-up the physical processors
setup(6) # set-up 6 processors
setup(logical=TRUE) # set-up physical and logical cores
} # }
