Function to check whether parallel computing should be used and how

Description

dCheckParallel is used to check whether parallel computing should be used and how

Usage

dCheckParallel(multicores = NULL, verbose = T)

Arguments

multicores
an integer to specify how many cores will be registered as the multicore parallel backend to the 'foreach' package. If NULL, it will use a half of cores available in a user's computer
verbose
logical to indicate whether the messages will be displayed in the screen. By default, it sets to true for display

Value

TRUE for using parallel computing; FALSE otherwise

Note

Whether parallel computation with multicores is used is system-specific. Also, it will depend on whether these two packages "foreach" and "doParallel" have been installed. It can be installed via: source("http://bioconductor.org/biocLite.R"); biocLite(c("foreach","doParallel")).

Examples

#dCheckParallel(multicores=2)
