2 CPUS, Plots not fast enough! August 2, 2006Posted by gordonwatts in computers.
I recently got a Dell dual-core system for home. With two processors I figured I could both run jobs that took 100% of one core and still look at email on the other core.
That didn’t last long. First thing I noticed was when I built the code I was running my build environment (MSVC) automatically took advantage of both cores. Wow, that was the fastest build I’d ever seen! But, I found myself annoyed that ROOT, my plotting package, was using only a single core instead of making the plot x2 faster by using both cores (yes, I did some tests, I was CPU bound, not I/O bound)!
