I am running the latest ubuntu with a Q6600 quad core cpu and the mpich2 that came with ubuntu<br>I can run my parallelized code over the four cores (i see it in 'top')<br>however, the speed increase over a single process is hardly improved for 2,3, or even 4 processes.<br>
<br>i was able to run the same code on a linux cluster through my school with speed increases as expected.<br>am i doing something wrong? <br><br>zach<br>
