[R] option for multi thread or multi core machines

[Uwe Ligges]

Standard answer:

It is possible to make use of more than 1 CPU cores by linking against 
some optimized BLAS (for matrix computations) or by parallelizing your 
code. Some packages might be of help, they are listed in the "high 
performance computing" task view on CRAN:

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.
