Hi, Could you please describe the current status of SLURM integration? I had a feeling srun supports direct launch of OpenMpi applications (without mpirun) compiled with the 1.5 branch. At least one of my colleagu succeeded on that.
But when I installed SLURM and the head revision of OpenMPI 1.5 branch I did not manage to run it without settings the SLURM_STEP_RESV_PORTS environment variable. I receive the following: orte_grpcomm_modex failed --> Returned "A message is attempting to be sent to a process whose contact information is unknown" (-117) instead of "Success" (0) -------------------------------------------------------------------------- [mir9:25477] *** An error occurred in MPI_Init [mir9:25477] *** on a NULL communicator [mir9:25477] *** Unknown error [mir9:25477] *** MPI_ERRORS_ARE_FATAL: your MPI job will now abort So I have 2 questions: 1. Is support of SLURM in the head revision of 1.5 branch stable enough to use it in the lab? 2. Does direct launch of mpi applications require setting the SLURM_STEP_RESV_PORTS environment variable? Thanks, Andrew Senin.
