Thanks for the reply Reuit. Yes OGS seems very stagnant - the current
version is from july 2012.
In terms of a newer version, I figure you mean using Son of GE? I probably
chose OGS when I setup this cluster a couple years ago because it came with
an OGS roll. I imagine my setup should migrate easily to Son of GE?
Univa GE Core looks old too, the master on github is 3 years old.
I imagine other forks will work with Rocks but I've never tried and don't
know about installation complications. I'll have to ask on the Rocks list.
Does anyone here have experience using Son of GE on Rocks?

Yes I saw too that load_sge_config may need to be run twice. I'm less
optimistic about this working if I switch to Son of GE - but if it fails I
can recreate by hand if I have to.
