<div dir="ltr"><div><div><div>Hello all.<br><br></div>I installed MPICH-3.0.4 today and I think I went through without any bugging issues. (Last time it was horrible...)<br><br></div>Problem is that when I run "cpi" to check if mpiexec is running correctly, the following message appears on the screen.<br>

1. no mpd is running on this host<br> 2. an mpd is running but was started without a "console" (-n option)<br>simba@asterix:/opt/mpich/mpich-3.0.4-build/examples$<br>===================================================================<br>
<br></div>So I did what the error message said and it looks like working fine.<br><br><div>===================================================================<br>simba@asterix:/opt/mpich/mpich-3.0.4-build/examples$ mpd &<br>
