<p>Comment (by Roland Haas):</p>
<p>It seems like a broken package selection. The compile script picked mpic++ to find out the libraries (and mpic++ is from mpich see the output of <code>readlink $(readlink $(which mpic++))</code> which is <code>/usr/bin/mpicxx.mpich</code>) but for some reason (no real idea why, maybe just bad luck in the order in which packages were installed) the equivalent for <code>mpirun</code> gives (<code>readlink $(readlink $(which mpirun))</code>) <code>/usr/bin/mpiexec.openmpi</code>.</p>
<p>I have verified that this is indeed what is happening, though there were other things wrong as shown by the earlier comments by Bill and I. You can try this out yourself by opening up a notebook on the server and just playing around with a hello-world MPI code or the readlink commands shown above.</p>
<p>I still do not know what causes the (*) to freeze or why the original Hello World Cactus run failed to start.</p>
