setupParallel {multiridge}

Setting up parallel computing

Description

This function sets up parallel computing by the package snowfall.

Usage

setupParallel(ncpus = 2, sourcefile = NULL, sourcelibraries =
c("multiridge","survival","pROC","risksetROC"))

Arguments

ncpus

Integer. Number of cpus to use. Should be >= 2.

sourcefile

Character. Additional source files to be loaded in parallel. Only required when parallel computing is also desired for functions not available in multiridge.

sourcelibraries

Character vector. Libraries to be loaded in parallel. Defaults to the libraries multiridge depends on.

Details

Parallel computing is available for several functions that rely on cross-validation. If double CV is used, parallel computing is applied to the outer loop, to optimize efficiency.

Value

No return value, called for side effects
