processes in R instead of allowing a single process to use all cores.
Apologies if this is utterly irrelevant.
Thank you,

Dear Arun,
thank you for the report. I agree with the analysis, detectCores() will
only report logical processors in the NUMA group in which R is running.
I don't have a system to test on, could you please check these
workarounds for me on your systems?
# number of logical processors - what
Dear R-devel list,
R's detectCores() function internally calls "ncpus" function to get the total
number of logical processors. However, this doesnot seem to take NUMA into
account on Windows machines.
On a machine having 48 processors (24 cores) in total and windows server 2012
installed, if
