These resource managment systems usually only support sequential processes.
For parallel (PVM) applications, the following environments may be used
to provide dynamic load balancing:
* MPVM (http://www.cse.ogi.edu/DISC/projects/mist/)
* DynamicPVM (http://www.fwi.uva.nl/research/pwrs/papers/group.html)
* CoCheck (http://wwwbode.informatik.tu-muenchen.de/~stellner/CoCheck.html)
The later will in the future be used by Condor to support resource
management for PVM applications. Currently, it uses the resource manager
interface of PVM and provides a simle resource manager that selects the
hosts based on the load on the machines. As the RAM size doesn't change
very much, this parameter would be easy to add and is up for negotiation
with me :-).

Cheers, Georg
