Feature request: Parallelisation for Windows #1

Closed KathaSchmack closed 1 month ago

KathaSchmack commented 1 month ago

It seems that "fui" cannot be run with parallel = TRUE on Windows. It produces the following error: Error in mclapply(argvals, unimm, mc.cores = num_cores) : 'mc.cores' > 1 is not supported on Windows

Did you first install the new fastFMM version? That error makes sense for the old fui() version but on the new one, Windows should use a different parallelization function.

Thank you! This happens with the fastFMM version 0.2.0 which got installed when I ran install.packages("fastFMM", dependencies = TRUE).

That makes sense: I don't think the new fastFMM version (with PC parallelization capability) has been added to CRAN yet (hopefully it will be in 1-2 weeks). But you can still download the new fastFMM version (with PC parallelization capability) with the following code:

install.packages('devtools') # not necessary if you already have devtools installed devtools::install_github('gloewing/fastFMM')

Let me know if parallelization works after you install the new version.
