If you are using Open-MPI 1.6.x you will get poor scaling if you use srun, so you have to use mpirun in that situation. I believe this is fixed in Open-MPI 1.8.x as that can use PMI2 with Slurm and fixes this scaling issue. -- Christopher Samuel Senior Systems Administrator VLSCI - Victorian Life Sciences Computation Initiative Email: sam...@unimelb.edu.au Phone: +61 (0)3 903 55545 http://www.vlsci.org.au/ http://twitter.com/vlsci
