You haven't told us much about your script. If it is a web script, then multiple hits on the script will kick off multiple copies of the script which could run simultaneously on different processors. Under Apache 1.x, each hit would be handled by a different httpd process (and different processor - potentially). Even if your script runs under mod_perl, it will still not be multi-threaded, so two invocations will safely run in parallel and will not share variables.

If it's not a web script, then most likely, it will run single threaded on a single CPU. You can compile Perl to support threading but you'd also need to write your Perl script to take advantage of threads.
