Your Perl script needs to be able to poll for completion of the tasks that have been spawned. If you can detect results being generated you could perhaps wait on that. If you have control over the code running on the cluster you could have the spawning process wait for completion of the cluster processes without needing to change your Perl.

Perl is the programming world's equivalent of English
