Do any of you disable swap on your compute nodes?
I brought this up in a presentation I gave last night on HPC system
administration, but realized I never actually did this, or know of
anyone who has. I would tweak the vm.overcommit_memory setting, but
that's not the same as disabling swap altogether. I'd like to try doing
this in the future, but I prefer to learn from someone else's mistakes
first.
