Hi all,
I can't get the functionality of the package parallel to work.
Specifically, makeCluster() hangs when I run it. I first noticed the
problem when trying to run Rstan with multiple cores and the traced it
back to the core package parallel. The following results in R hanging
after the call to makeCluster.
library(parallel)
# Calculate the number of cores
no_cores <- detectCores() - 1
# Initiate cluster
cl <- makeCluster(no_cores)
I'm running MacOS High Sierra 10.13.3 (17D47) on a MacbookPro 2017
laptop with 4 cores.
platform x86_64-apple-darwin15.6.0
arch x86_64
os darwin15.6.0
system x86_64, darwin15.6.0
status
major 3
minor 4.3
year 2017
month 11
day 30
svn rev 73796
language R
version.string R version 3.4.3 (2017-11-30)
nickname Kite-Eating Tree
The problem replicates in R --vanilla
I've spent hours googling for solutions but can't find any reports of
this problem. Any help would be appreciated.
Florian
