I’m trying to run a Palabos application on baobab, wich have been built using foss and CMake modules.
I’m getting weird warning message, but the program seems to work fine.
Does this message indicate I’m doing something wrong ?
[burdetj@login2 build]$ srun --ntasks 2 ./micrometer_stent_sfdm $HOME/patient2
srun: job 39418151 queued and waiting for resources

it seems it’s related to the fact that openib BTL is deprecated. We should recompile OpenMPI with --without-verbs option. I did some tests, it seems it’s a warning only, the performances aren’t impacted.
