I guess you just have to make sure the machine file you're trying to use is there. What "ls -l $TMPDIR/machines" is showing ?

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
