It does seem like a good idea on the face of it. I would have to check if we do that, but I know that the jobs we tend to run don't happen to come close to using all of the physical memory on the machines anyway, so there ought not really be an impact, I'd think.

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. -- Prentice _______________________________________________ Beowulf mailing list, [email protected]<mailto:[email protected]> sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
