Hi, A previous thread suggests that R on Windows is multi-threaded
http://tolstoy.newcastle.edu.au/R/help/03b/6946.html When I'm running R 2.5.1 on a dual core pc I get Rgui.exe uses up to 50% of the available cpu and the rest is not used. i.e. it only uses one cpu. I'm soon going to get a nice shiny new 8 cpu machine which it would be very nice to fully utilize. Is there any way to get R to use all the cpus - should this happen automatically? Many thanks, Regards, David [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
