I notice that R basic installation does not take advantage of multi-thread or multi-core processors. Is there an option for multi-threaded processors? I currently run all of my analysis on thinkpad laptop and most processing is very quick, however, when I run stepAIC with interaction terms it can take a couple of hours to complete. I have tried running the same process and a quad core machine 64 bit machine and process finishes about 10 mins.
Is the improved speed purely a result being able to take advantage of the extra memory or does the version that installs on a 64 bit machine automatically uses the multi-core processor?
