stackr_parallel: hack to switch function for parallel computation based on OS

In thierrygosselin/stackr: Run stacks software pipeline for RADseq analysis inside R

Description

parallel::mclapply doesn't work on Windows, because forking is not supported. This function defines a socket version of mclapply for windows computer An implementation that switch automatically the parallel process when detecting the os. The code below was inspired from parallel mclapply, Nathan VanHoudnos, Kevin Kuang, Peter Solymos and Eric Archer.

Usage

mclapply_win(
  X,
  FUN,
  ...,
  mc.preschedule = TRUE,
  mc.set.seed = TRUE,
  mc.silent = FALSE,
  mc.cores = NULL,
  mc.cleanup = TRUE,
  mc.allow.recursive = TRUE
)

.stackr_parallel_mc(
  X,
  FUN,
  ...,
  mc.preschedule = TRUE,
  mc.set.seed = TRUE,
  mc.silent = FALSE,
  mc.cores = getOption("mc.cores", 2L),
  mc.cleanup = TRUE,
  mc.allow.recursive = TRUE,
  affinity.list = NULL
)

.stackr_parallel(
  X,
  FUN,
  ...,
  mc.style = "ETA",
  mc.substyle = NA,
  mc.cores = getOption("mc.cores", 2L),
  ignore.interactive = getOption("ignore.interactive", F),
  mc.preschedule = TRUE,
  mc.set.seed = TRUE,
  mc.cleanup = TRUE,
  mc.allow.recursive = TRUE
)
