Subject: [OMPI users] Disabling irqbalance service for better performance of MPI jobs
From: Rahul Nabar (rpnabar_at_[hidden])

I have already been using the processor and memory affinity options to
bind the processes to specific cores. Does the presence of the
irqbalance daemon matter? I saw some recommendation to disable this
for a performance boost. Or is this irrelevant?

I am running HPC jobs with no over- nor under-subscription. These are
8 core Nehalem servers.
