OpenMPI. The current versions of Slurm and Open MPI support task launch using the srun command. It relies upon Slurm managing reservations of communication ports for use by the Open MPI version 1.5. If OpenMPI is configured with --with-pmi either pmi or pmi2, the OMPI jobs can be launched directly using the srun command. This is the preferred mode of operation.

Slurm (> 2.6, > 14.03) installs PMI-2 support by default. Older versions of Slurm install PMI-1 by default. If you desire PMI-2, Slurm requires that you manually install that support. When the --with-pmi option is given, OMPI will automatically determine if PMI-2 support was built and use it in place of PMI-1.

If Slurm and OpenMPI are recent versions, make sure that OpenMPI is compiled with Slurm support (run ompi_info grep slurm to find out) and just run srun bin/ua.B.x inputua.data in your submission script.. Alternatively, mpirun bin/ua.B.x inputua.data should work too. If OpenMPI is compiled without Slurm support the following should work:
