Dear Yugi,

I allow myself to continue this post as the same problem occurred when running examples in parallel on Cluster:

MASTER PROCESSOR NUMBER 0 OF THE GROUP OF 1
P_INIT: FILE PARAL IS INCONSISTENT WITH MPI PARAMETERS
MPI NCSIZE = 1
PARAL NCSIZE = 16

After the warning message the example kept running and could be completed, but the time costed was close to that of serial mode, so I suppose the pb comes from my mpi settings. Could you please help me check the config file enclosed?

Besides, is there a simple case to check the mpi on Cluster? Just like you posted at #27502.

Thank you very much!
Yunhao

yugi OFFLINE openTELEMAC Guru Posts: 851 Thank you received: 244	This message means that the number of cores detected by MPI was 1. So i guess the error comes from your mpi_cmdexec. Maybe use mpirun instead of srun.

Yunhao Song OFFLINE Senior Boarder Posts: 118 Thank you received: 9	Do you mean changing the mpi_cmdexec into mpirun -wdir <wdir> -n <ncsize> <exename>? Just FYI, slurm was used to submit the job and before launching the example some modules were loaded as below. module load anaconda/2.7.13 module load openmpi/2.1.5gcc5.3.1

yugi OFFLINE openTELEMAC Guru Posts: 851 Thank you received: 244	Yes something like that is there any info on your cluster on how mpi applications should be launch ? I am afraid that what srun -n <ncsize> <exe> is doing is launching ncsize time one <exename>

Yes here is a mpi test case:

[simon@n0255 ~]$ which mpicc
/home/software/mpich_3.2/bin/mpicc
[simon@n0255 ~]$ mpicc -o mpitest mpitest.c
[simon@n0255 ~]$ srun --mpi=pmi2 -p hpib -n 4 mpitest
Hello world: rank 0 of 4 running on n0317
Hello world: rank 1 of 4 running on n0317
Hello world: rank 2 of 4 running on n0317
Hello world: rank 3 of 4 running on n0317

Yunhao Song OFFLINE Senior Boarder Posts: 118 Thank you received: 9	Dear Yugi, Thanks for your help, the mpi_cmdexec: mpiexec -wdir <wdir> -n <ncsize> <exename> worked. Best regards,
