We installed Code_Saturne 7.0.0 on CENTOS 7 and everything is working just fine when running in serial mode.
The problem happens when the case is launched on multiple cores :
1 - On the GUI terminal, I had the following error (cf code_saturne_error). 2 - I tried changing the mpi module that is loaded by adding
- setenv OMPI_MCA_pml "ucx"
- setenv OMPI_MCA_btl "^vader,tcp,openib"
I changed back the way it was on the openmpi module but still no error.
I also tried running the case on our cluster : it worked on 1 proc, but the same thing happens with more than one :
- No error in the files generated by SLURM
- No listing
- The slum log on the master node shows that the run was succesful
Thank you,
