Re: [OMPI users] Oversubscription of nodes with Torque and OpenMPI

Really shouldn't matter - this is clearly a bug in OMPI if it is doing mapping as you describe. Out of curiosity, have you tried the 1.7 series? Does it behave the same? I can take a look at the code later today and try to figure out what happened. On Nov 22, 2013, at 9:56 AM, Jason Gans wrote

[OMPI users] Oversubscription of nodes with Torque and OpenMPI

Hello, I would like to run an instance of my application on every *core* of a small cluster. I am using Torque 2.5.12 to run jobs on the cluster. The cluster in question is a heterogeneous collection of machines that are all past their prime. Specifically, the number of cores ranges from 2-8. H
