The ATLAS project also had such and interface, and I believe still does.
I want to say that it was a part of that set of grid tools whose name I
can never remember -- Globus?

It may be just what you are looking for if your cluster is very
grid-like in that it primarily runs lots of independent EP tasks.

Look at www.globus.org.  In fact, look at:

http://www.globus.org/grid_software/computation/gram.php

which may be if not exactly what you want, at least a framework you can
work with.
