In my limited experience, you really don't want to split parallel jobs across queues (and you only add queues if there's something you have to hang off them). I don't really understand what the complaint is here otherwise. OMPI with h_vmem enforced works reasonably well for us (with a single queue). > This was a bug and is fixed in the meantime from Open MPI 1.5.5 on. > > https://svn.open-mpi.org/trac/ompi/changeset/26163 > > It will always add up all slots for a machine even if they come from > different queues now. You'll still get potential confusion from different TMPDIRs, though. I never established whether there was any problem replacing the queue name with the cell name in TMPDIR construction, but I have a patch lying around to do it. >> I'll think of this and add it as a comment to the ticket.

I'd be happy to have reports that might improve SGE (if I or someone else understands the issue), but I'm afraid I've been flamed for trying to help OGS users. -- Community Grid Engine: http://arc.liv.ac.uk/SGE/ _______________________________________________ users mailing list [email protected] https://gridengine.org/mailman/listinfo/users
