Hi, Our discussions about 64 bit R has led me to another thought. I have a nice dual core 3.0 chip inside my Linux Box (Running Fedora 11.) Is there a version of R that would take advantage of BOTH cores?? (Watching my system performance meter now is interesting, Running R will hold a single core at 100% perfectly, but the other core sites idle.) Thanks! -- Noah
Also have a look at the "foreach" package: http://finzi.psych.upenn.edu/R/library/foreach/html/foreach-package.html On Fri, Sep 11, 2009 at 11:05 PM, Noah Silverman <noah@smartmediacorp.com>wrote:> Hi, > > Our discussions about 64 bit R has led me to another thought. > > I have a nice dual core 3.0 chip inside my Linux Box (Running Fedora 11.) > > Is there a version of R that would take advantage of BOTH cores?? > (Watching my system performance meter now is interesting, Running R will > hold a single core at 100% perfectly, but the other core sites idle.) > > Thanks! > > -- > Noah > > ______________________________________________ > 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. >-- ---------------------------------------------- My contact information: Tal Galili Phone number: 972-50-3373767 FaceBook: Tal Galili My Blogs: http://www.r-statistics.com/ http://www.talgalili.com http://www.biostatistics.co.il [[alternative HTML version deleted]]

When I discovered the package 'foreach', I wrote the following piece completely overwhelmed by enthusiasm: http://lifeofknudsen.blogspot.com/2009/07/most-of-work-i-do-in-r-has-to-do-with.html It's very basic, but maybe you'll find it useful.
