Subject: [OMPI users] Maui + Slurm + OpenMPI
From: Romaric David (david_at_[hidden])

I am trying to make use of Maui 1.3.6p19 + Slurm 1.2.29 + OpenMPI 1.2.6 together.

I am currently trying to have slurm procs --ntasks-per-node specification work
with openmpi.

I submit a simple mpirun job with :
sbatch -N 2 --ntasks-per-node=1 myscript where myscript only contains an mpirun command.

When submitting this script using slurm's builtin scheduler, all runs perfectly and processes
get dispatched, one per node, allright.

When using maui scheduler, the mpi program does not start : the mpi executable
does not get read.

Would mpirun be confused by the environment transmitted by slurm/maui ?

Do you have a clue on this ?
