Hi, Using openmpi-1.2.6 with SGE 6.1u3 when I submit a job script containing: mpirun -n $NSLOTS -machinefile $TMPDIR/machines ~/openmpi_test
it produces following error in the output file: cat: /tmp/174.1.all.q/machines: No such file or directory -------------------------------------------------------------------------- Open RTE was unable to open the hostfile: /tmp/174.1.all.q/machines Check to make sure the path and filename are correct. -------------------------------------------------------------------------- [comp5...] [0,0,0] ORTE_ERROR_LOG: Not found in file rmgr_urm.c at line 358 [comp5....] mpirun: spawn failed with errno=-13 Earlier I had been running jobs with MPICH2 without any problem. Any ideas on how to get arround it please? thanks Azhar
