The parallel computation failed

System Modules TELEMAC-2D

I installed Telemac v8p5 in a Linux environment, and then I ran the command python -m telemac2d xqh.cas --ncsize=4 to perform parallel computing. I encountered the following error:

At line 136 of file /home/slf/TELEMAC/telemac-mascaret-v8p5r0/sources/utils/bief/read_partel_info.f (unit = 17, file = ‘T2DPAR00003-00003’)

Fortran runtime error: Bad integer for item 4 in list input

I am not sure where the problem lies. My MPI version is mpirun (Open MPI) 4.1.6.

I would greatly appreciate it if anyone could help me.

Hi

it’s look like the partitioning step doesn’t work correctly.

Look the partel log file

Hi,

I have exactly the same problem (and no error message in the partel log file).

Did you mange to fix this issue (and how) ?

Could you share your files in order to let us try on our side and check?

As Telemac validation ensure sequential and parallel test on different architectures, what you observe is not normal but could be related to your model.

Hi [name removed],

Thank you for your help.

The IT staff just solved the issue by switching the GNU compilateur de Gnu from 13 to 12.

Everything works well now.
