SimParEx executes a program (worker) on many computers (farm) in parallel and collects the results. It needs minimal requirements (TCP, SSH, Perl) and is designed platform independent. On the slaves nothing in particular needs to be installed. The worker should be a commandline program. The task definition is flexible and supports commandline construction and input file generation. It can not compete with the large Distributed Resource Management System (DRM) tools like Sun's Grid Engine or Condor, but it does a similar job with little efforts.
