TELEMAC-MASCARET Forum: run and configure MPI (1/1)

run and configure MPI 9 years 1 month ago #18559

Hello,

I'm build my own cluster for few projects (for now only with 2 computers for test). I use gfortran and MPICH2.

I have compiled the systel.cfg and run the test case “digue” for telemac2d. I have used the command :

$ sudo mpiexec -f /home/promethee/machinefile -n 2 python /home/promethee/telemac/scripts/python27/telemac2d.py /home/promethee/test/digue/t2d_digue.cas

I have this error message with I suppose a problem with PARTEL
or my configuration(see the attachment). I put also the config file.

hoping have some help from the community

Best regards

yugi OFFLINE openTELEMAC Guru Posts: 851 Thank you received: 244	Hi, In your temporary folder there should be a file named partel_T2DGEO.log. Could you post it here it should contain the answer. Hope it helps.

Hi

I comeback to you again. I have reinstalled the cluster and did some tests.
The configs file is in attachment. I have tried to start a run in parrallel using the processeurs from my master and my node (two processors for each machine).
For start a job i use the command:
mpiexec -n<number of processor> -f <host_file> telemac2d.py <cas_file>

The job starts correctly but the processors don't work together but separately. Concretely when i start a job with 3 processors for example, I have the same job running on two processors so two result files (the third one being the HYD_Proxy).

I have the same problem when i start the job on one machine as well.

I suppose a mistake on my configs file but i don't know where. If the community can enlighten me …

Julien
