I am having an issue that I do not know how to solve. Say I have 2 nodes (node1 and node2) each with 24 cores, I have software where I have a license for 32 cores. I want to be able to configure node1 to ONLY accept jobs for that software, and I want node2 to reserve 8 cores out of its'24 to be exclusively for that software, but the remaining 16 be free for any other program to use. Is there a nice way to do this in Torque? I think I can find a way to deal with node1 by defining node properties, but I can't figure out a way to allocate node2 as needed. Is there a simple way to do this? Thanks

  • As Danila points out below, you can use cpuset to set the task scheduler affinity for one particular core. HOWEVER, why do you think you're better at managing a processor's time than the kernel scheduler? – Tom O'Connor May 08 '13 at 08:23

I am not sure about Torque, but I had similar task which I resolved with tweaking "cpuset" for Condor. You might look into that and find something helpful for your task (user space shielding e.t.c.)
