<p class="MsoNormal">The MPICH docs say <b><span style="color:red">the following</span></b><span style="color:red">
</span>about running under Slurm. Is “sbatch” one of the launchers for which special configuration is necessary?<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">A: MPICH's default process manager, Hydra, internally detects and functions correctly with SLURM. No special configuration is needed.

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><b><span style="color:red">However, if you want to use SLURM's launchers (such as srun), you will need to configure MPICH with:

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">In addition, if your slurm installation is not in the default location, you will need to pass the actual installation location using:

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">./configure --with-pmi=slurm --with-pm=no --with-slurm=[path_to_slurm_install]<o:p></o:p></span></p>
