You should elaborate on your requirements. Is this intended to be portable? Windows/linux? Do you need it as perl code? There are utilities that can help in running parallel tasks (e.g. xargs). Do you need those jobs as separate processes; perhaps a threaded version might suit you as well?

Have you searched for modules (e.g. Parallel::ForkManager)? Do you actually need a robust, efficient solution or is this homework?
