If you are looking for _free_ batch systems, you should choose SGE.

I believe you can setup multiple "SGE_CELL"s to partition your cluster
(I've never played with that before)

Or you can use Globus, or other 3rd party scheduler on top of SGE.

You talking about SGE 5.2.x?

Chris Black must be talking about SGE 5.3, which has several advanced
nice scheduler features:

Ron Chen has been talking about the new shadow master on the SGE
mailing list. which he said will improve fault tolerance, but I've
never heard anything yet...

correct.

Also, you may want to look at job arrays, which is not available in
PBS. (the other batch system which has job arrays is LSF)

You can download the SGE source from:
