Dear Freesurfers,
I am currently running 4 subjects, each on a separate x11 window. With 19 subjects at hand and subsequent manual editing, I can't resist the temptation to open more x11 terminals and to submit more jobs. However, how do I know that I max out the machine's computing power?
Hard drive info Processor Name: Intel Core i5 Processor Speed: 2.7GHz Number of Processors: 1 Total number of cores: 4 Memory: 16GB
Thank you very much!
Sincerely, Ye
Hi Ye, if you have 4 cores, then it will not speed anything up to run more than 4 at one time (it will actually slow things down to run more at once). doug

Hi Ye
you have 4 cores, so running more than that won't help (the others will just slow down). You might start running out of ram with more than 4 in any case, but I think 4 should fit (Nick can correct me if I'm wrong)
cheers Bruce
