i would have thought the answer is in 'man g77' - look for OpenMP or
threads. You may also wish to look up 'mpich' in an Internet search
engine. 

so, "yes" you can get your programs to use both CPUs - how well they do
so is yet another issue.

if you're asking about op sys tasks on >1 CPUs pls start a  new thread
