Dear Debian People: When I run R on a grid machine, I have a "Machinefile" with the names to run with mpirun and all is well. I'd like to run mpirun on a multicore laptop, but I'm not sure how to make the "Machinefile" I tried: localhost cpu=4 but it doesn't seem to be working. This is using a quad core laptop with Karmic Koala. Thank you for any help. Sincerely, Erin Erin M.
