Dear Tomas, thank you for looking into this. Here's the output: # number of logical processors - what detectCores() should return out <- system("wmic cpu get numberoflogicalprocessors", intern=TRUE) [1] "NumberOfLogicalProcessors \r" "22 \r" "22 \r" [4] "20 \r" "22 \r" "\r" sum(as.numeric(gsu...

...t any possible problem. As I mentioned earlier, in older versions of R one can as a workaround use "wmic" to detect the number of processors on systems with >64 logical processors (with appropriate error handling added as needed): # detectCores() out <- system("wmic cpu get numberoflogicalprocessors", intern=TRUE) sum(as.numeric(gsub("([0-9]+).*", "\\1", grep("[0-9]+[ \t]*", out, value=TRUE)))) #detectCores(logical=FALSE) out <- system("wmic cpu get numberofcores", intern=TRUE) sum(as.numeric(gsub("([0-9]+).*", "\\1", grep(&...

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 NUMA is enabled and has 2 nodes (node 0 and node 1 each having 24 CPUs), then R's

...etectCores() 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 detectCores() should return out <- system("wmic cpu get numberoflogicalprocessors", intern=TRUE) sum(as.numeric(gsub("([0-9]+).*", "\\1", grep("[0-9]+[ \t]*", out, value=TRUE)))) # number of cores - what detectCores(FALSE) should return out <- system("wmic cpu get numberofcores", intern=TRUE) sum(as.numeric(gsub("([0-9]+).*...
