Someone else suggested the snow package, but I don't think it is available for windows. I have been able to get the nws package to work on a duel core machine using windows and it did speed up my tests (and was fairly straight forward to use).

Subject: [R] Is R on Windows multi-threaded

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
