Just also want to mention that Moab is not open-source, and I don't think we

Hi list again,
something seems not be working as I *expect* it to be.
Several jobs are waiting and are asking for a reservation, waiting for
12 slots to become free and are at the top of the priority list.
Several other jobs with less priority and asking only for 4 slots get
backfilled, but

BTW, we dual-boot the RHEL kernel the UEK (haven't tried UEK2 yet).
The advantage of this setup is that we could always go back to the
RHEL kernel with just a reboot. Also, we just need to setup OGS/GE (or
any other software packages) once and can test it with both kernels.
