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. Am I barking up the wrong tree? -- Michael Lush Computer Officer CR-UK Genetic Epidemiology Unit University of Cambridge Strangeways Research Laboratory Worts Causeway, Cambridge CB1 8RN Tel.: +44 (0)1223 748643 Web: http://ccge.medschl.cam.ac.uk/
