Thanks a lot. I certainly don't mind if the program is actually using 8
processors and just showing one process. I was worried that probably its running
8 processes on a single processor and that's why its showing one process with
800% usage, because generally when I run a parallel program I see 8 processes
with 100% usage. Thanks for the explanation.
