Subj : Re: Running two pthreads with dual processors To : comp.programming.threads From : D'artagnan Date : Fri Feb 25 2005 06:41 am This is exactly how I did it: using top. I had both threads loop until I hit Ctrl-C. Then I used 'top' to see what's happening. Only one cpu is doing job (idle < 10%), the other was 99% idle. Then I realized that I was using gcc (an old version). I switched to icc and found that both cpu's are busy. I really don't know if this makes sense, but this is what I observed. Best .
