Hi, I'm setting up a new cluster. I'd like to limit jobs to a set number of cores on each host. Jobs default to 1 slot currently, and I'm using pe_serial to keep parallel jobs restricted to single hosts because we use shared-memory parallel apps here.
But on an older cluster here, jobs will spill out onto more cores when the app's number of threads isn't limited by the user. I found a post that mentions the '-binding' option for qsub: "Here, we are also binding each job to a single core. -binding linear:1" Does this really do that? I can't quite tell from the qsub documentation. If someone uses -pe my_pe 4 -binding linear:4 to request for cores, will their job placement be limited if no host as 4 consecutive cores to allocate? Thanks -M
