<p>Comment (by Roland Haas):</p>
<p>This seems to be an OpenMPI issue, in that it checks for <code>rsh</code> or <code>ssh</code> in its <code>$PATH</code> pretty much before it does anything else even when no remote execution is needed.</p>
<p>For example these:</p>
<div class="codehilite"><pre><span></span>OMPI_MCA_plm_rsh_agent=sh mpirun -n 2 whoami
mpirun -mca plm_rsh_agent sh -n 2 whoami
</pre></div>


<p>both work.</p>
<p>A fix may be to set the <code>plm_rsh_agent</code> option in <code>/etc/openmpi-mca-params.conf</code>or in <code>$HOME/.openmpi/mca-params.conf</code> after which the simple</p>
<div class="codehilite"><pre><span></span>mpirun -n 2 whoami
</pre></div>


<p>works.</p>
