Dear all, I recently installed QE on a virtual cluster configured with StarCluster. QE configures and compiles without errors. However, when I submit a parallel calculation on 16 processors, the following is written near the start of the output file:
Parallel version (MPI), running on 1 processors The line is repeated 16 times in the output. To me it seems like I am actually running 16 single processor calculations that all write to the same output file (stdout in this case). The way I submit this calculation, is the following: I write the following submit script (submit.sh): cp /path/to/executable/pw.x mpirun -np 16 pw.x -in input.inp Then I submit the job with the following command: qsub -cwd -pe orte 16 ./submit.sh The queuing system of StarCluster is Open Grid Scheduler. For the line in the submit script, I have also tried several alternatives such as: mpirun pw.x -in input.inp mpirun pw.x -inp input.inp mpirun -np 16 pw.x -inp input.inp mpirun -np 16 pw.x < input.inp In the archives of this mailing list I have seen some similar problems, but in spite of this I was still not able to solve my problem. I would appreciate very much if someone could give me suggestions on how to solve the problem. Thanks in advance. Yours sincerely, Torstein Fjermestad University of Turin, Italy
