auto parallelization

[chljl]

We got a 4-processor xeon workstation running xp. How can I take the advantage of multi-processor system without manually writing the code in parallel form? I tried the auto parallelization option -Qparalell. But it doesn't work. It makes two cpu running without any time reduction.

Thanks a lot.

It could be that your application does not take well to running in parallel. Auto-parallelization can't always tell what is safe to run in parallel. You're better off to use OpenMP directives to let the compiler what can be run in parallel.
