palply {CHNOSZ}

Conditional Parallel Processing

Description

Use multiple processors for large calculations.

Usage

  palply(varlist, X, FUN, ...)

Arguments

...

equivalent to the same argument in parallel::parLapply

varlist

character, names of variables to export using parallel::clusterExport

X

vector, argument for lapply or parLapply

FUN

function, argument for lapply or parLapply

Details

palply is a wrapper function to run parallel::parLapply if length of X > thermo()$opt$paramin and multiple cores are available, otherwise it runs lapply. Note that parLapply is called with methods set to FALSE. If lots of package startup messages are created when running parallel::makeCluster (which is called by palply), it can probably be stopped by adding a test for interactive sessions around any library commands in the Rprofile.
