Has anyone successfully requested multiple cpus for one multi-thread job?
I'm doing this:
priority = 20
requestcpus = 3
requirements = (memory>=3000)
The job still occupies one cpu, rather than two. resulting my condorpool
over-saturated 2X threads.
To fill in the context, I'm submitting jobs to condor through pegasus
RequestCPUs only works on partitionable slots. If you want to be sure
your job only runs on a machine with 3 CPUs to give your job you can add
CPUs >= 3 to your Requirements. Of course, that'll likely just cause
your job never to run without extra configuration on your execute nodes
to create slots with multiple CPUs, by default they all have 1.
