autoParApply: *apply with auto-parallelization if available

In xrobin/xavamess: Useful Miscellaneous Functions

Description

autoPar*apply functions guess the number of cores to use and run in parallel if possible. “L”, “S” and “” (nothing) are available. This function will make all objects in the global environment, and all currently loaded packages available to the parallel cluster nodes. This may fail in unexpected ways if other environments are attached to the search path.

Usage

autoParLapply(X, FUN, .maxCores = NULL, ...)

autoParSapply(X, FUN, .maxCores = NULL, ...)

autoParApply(X, MARGIN, FUN, .maxCores = NULL, ...)

Arguments

X, MARGIN, FUN, ...	arguments to lapply, sapply and apply or their parallel equivalents
.maxCores	limit the number of cores.

Examples

## Not run: autoParLapply(1:10, function(x) x^2)
## Not run: autoParSapply(1:10, function(x) x^2)
## Not run: 
x <- array(1:30, dim=c(2, 5, 3))
autoParApply(x, 1, sum)
autoParApply(x, c(1, 3), sum)

## End(Not run)
