Re: Interesting
SGE seems to have come from the world of server farms than HPC clusters.
However, SGE does have the concept of parallel environments, which allows
the running of mpi or pvm type applications.
I am testing SGE out as a possible replacement to OpenPBS. It seems to
be working pretty well. Very fast, no stability problems yet. However,
I only have it running on 37 nodes. My goal short term is to test
it on about 400 nodes, and about 800 nodes in early fall.
So far it does everything I would need it to do if I move away from
OpenPBS. My real concern is scalability and stability at large node counts
for large numbers of jobs which I already know doesn't work very will
with OpenPBS.
