Sure. Here's the stderr of a job submitted to my cluster with 'qsub -pe mpi 8 -binding linear:2 myScript.com' where myScript.com runs 'mpirun -mca ras_gridengine_verbose 100 --report-bindings ./unterm': [exec4:17384] System has detected external process binding to cores 0022 [exec4:17384] ras:gridengine: JOB_ID: 59352 [exec4:17384] ras:gridengine: PE_HOSTFILE: /usr/sge/default/spool/exec4/active_jobs/59352.1/pe_hostfile [exec4:17384] ras:gridengine: exec4.cluster.stats.local: PE_HOSTFILE shows slots=2 [exec4:17384] ras:gridengine: exec2.cluster.stats.local: PE_HOSTFILE shows slots=1 [exec4:17384] ras:gridengine: exec7.cluster.stats.local: PE_HOSTFILE shows slots=1 [exec4:17384] ras:gridengine: exec3.cluster.stats.local: PE_HOSTFILE shows slots=1 [exec4:17384] ras:gridengine: exec6.cluster.stats.local: PE_HOSTFILE shows slots=1 [exec4:17384] ras:gridengine: exec1.cluster.stats.local: PE_HOSTFILE shows slots=1 [exec4:17384] ras:gridengine: exec5.cluster.stats.local: PE_HOSTFILE shows slots=1 Chris -- Dr Chris Jewell Department of Statistics University of Warwick Coventry CV4 7AL UK Tel: +44 (0)24 7615 0778
