I run gcc on a linux pentium II and I am trying to
compile a C code so that it uses the two processors
I have on this machine. Is that possible and what are the compilation
instructions ?
Regards,
Valerie Cayol

Compile your kernel with multiprocessor support.
The OS scheduler will determine which process runs on which processor.

Unless you find a compiler which supports auto-parallelization,
you must write in p-threads or openmp directives, or use MPI or
one of the older schemes along that line. If you're looking for
performance, a hardware upgrade will be simpler.
