Hello, I use R on a Microsoft Windows machine. Is it possible for me to open multiple windows of R, have them run the same program but for different data sets, and get accurate results? It takes 8+ hours to run the program so I want to multitask as much as possible. Thanks in advance, George Chen

Dear George, I think it will depends on the amount of memory that each your session will need. Case each session use a big amount of memory, may be your some of your sessions will get error. I also think that you will not save time if you start several dataset at same time, because windows is windows.
Errrr, you obviously never tried. Please don't speculate. For CRAN, we are installing and checking all > 1600 CRAN packages on a Windows machine in less than 5 hours, because it runs in parallel on 8 CPU cores. In scaling is almost linear up to the number of actual CPU cores in your system - as long as a sufficient amount of memory is available. Uwe Ligges
By other side, I think that on linux you can get better results. Good luck. miltinho brazil On Wed, Feb 4, 2009 at 10:22 PM, George Chen <glchen at stanford.edu> wrote:
