[Beowulf] disabling swap on cluster nodes?

[Prentice Bisbal]

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.
