I remember you from the various SGE mailing lists. Welcome to the Slurm
club. You might want to join the Slurm mailing list, too, and post this
over there, too. I'm sure there are plenty of Slurm Admins who used to
be SGE admins. The Slurm documentation at slurm.schedmd.com is very
good. This link may help for submission options and basic user commands:
but I don't think you'll find a simple diff. explanation about
architecture and admin commands.
It's a shame the life sciences are so resistant to change. I know
exactly what you're talking about. When I first started supporting life
sciences, they were still insisting on SGI workstations when everyone
else in the Scientific Computing world had switched to Linux, and a
Linux workstation with a QuadroFX card could run circles around the SGI
workstations for only 1/4 of the cost. And don't get me started on the
cost/performance comparison between an 8-processor Origin server and a
1U Linux server!
And yeah, the last cluster I supported using SGE was doing Genomics work.
Good luck on your transition.
