Hello! Having a quick look in your email I found a simple mistake:
The CPUs should the total number of Virtual Cores per node and not the number of Sockets. So set: "CPUs=32" and maybe your problems will be solved ;) Best Regards, Chrysovalantis Paschoulas On 11/27/2014 12:41 PM, Michael Lush wrote: Were using SLURM 2.3.2 on Ubuntu 12.04 to manage large numbers of independent single threaded jobs via sbatch --wrap="impute file1.txt" the nodes are defined as NodeName=gen[02-13] CPUs=2 RealMemory=192000 Sockets=2 CoresPerSocket=8 ThreadsPerCore=2 State=UNKNOWN Which allows 16 jobs to run on a node. For certain applications we'd like to run 32 jobs on a node, I've set MaxTasksPerNode=32. I've toyed with --ntasks with little success.
