<div>Hello Roland and Ian,</div>

</div>
<div>I did check for OpenMPI and MPICH package, it seems there is only one installed I am attaching the result so you can see.</div>
<div>I also checked the other two command to know the compatibility but they seem to have different path. </div>

<div>"dpkg -S $(readlink -f $(ldd exe/cactus_sim | gawk '/<a href="http://libmpi.so/%7Bprint$3%7D'" target="_blank">libmpi.so/{print$3}'</a>)) " gives "libopenmpi2:amd64: /usr/lib/x86_64-linux-gnu/openmpi/lib/libmpi.so.20.10.1" as output.</div>

<div>They are both openmpi, so that doesn't immediately throw up any red flags.</div>

<div>I have tried "simfactory/bin/sim run static_tov --parfile=par/static_tov.par --procs=2" and "./simfactory/bin/sim create-run helloworld --parfile arrangements/CactusExamples/HelloWorld" and "exe/cactus_sim" in all the above cases I got the same

<div><br>
</div>
<div>From the dpkg output, you have both mpich and openmpi installed. </div>
<div><br>
</div>
<div>
<div>ii mpich 3.3~a2-4 amd64 Implementation of the MPI Message Passing Interface standard</div>
<div><br>
</div>
<div>
<div>ii openmpi-bin 2.1.1-8 amd64 high performance message passing library -- binaries</div>
<div>ii openmpi-common 2.1.1-8 all high performance message passing library -- common files</div>
</div>
<div><br>
</div>
</div>
<div>Can you tell us the output of </div>
<div><br>
</div>
<div>which mpicc</div>
<div><br>
</div>
<div>It should be /usr/bin/mpicc</div>
<div><br>
</div>
<div>Then type</div>
<div><br>
</div>
<div>mpicc -show</div>
<div><br>
</div>
<div>to see which MPI package it is using. It should be something like</div>
<div><br>
</div>
<div>gcc -I/usr/lib/x86_64-linux-gnu/openmpi/include/openmpi -I/usr/lib/x86_64-linux-gnu/openmpi/include/openmpi/opal/mca/event/libevent2022/libevent -I/usr/lib/x86_64-linux-gnu/openmpi/include/openmpi/opal/mca/event/libevent2022/libevent/include -I/usr/lib/x86_64-linux-gnu/openmpi/include
-pthread -L/usr//lib -L/usr/lib/x86_64-linux-gnu/openmpi/lib -lmpi<br>
<br>
</div>
<div>so we can see which one is the default? When you build the ET, the MPI thorn build script runs mpicc to find out which MPI to use.</div>
<div><br>
</div>
<div>It's possible that you might have to uninstall mpich, but I'm not sure. There *shouldn't* be a fundamental reason why you can't have both installed and just use one of them, but there might be technical reasons why it doesn't work.</div>
