Hi Reuti, I do no reset any environment variable during job submission or job handling. Is there a simple way to check that openmpi is working as expected with SGE tight integration (as displaying environment variables, setting options on the command line, etc. ) ? Regards, Eloi On Friday 21

Hi there, I'm observing something strange on our cluster managed by SGE6.2u4 when launching a parallel computation on several nodes, using OpenMPI/SGE tight- integration mode (OpenMPI-1.3.3). It seems that the SGE allocated slots are not used by OpenMPI, as if OpenMPI was doing is own round-robi
