Principally our reading algorithm works with any number of processes, including one.</div><div><br></div><div>At the moment, we always have to start a pvserver instance with MPI (i.e. mpiexec -n NN pvserver), start a normal client, and connect to the pvserver instance if we want to use the plugin - this also works for NN=1. However, when I start the ParaView client, the plugin crashes because MPI was not loaded/started. Thus we always have to go through the extra steps of starting a pvserver if we want to use the plugin.</div><div><br></div><div>Thus my question is whether there is a way to either start/load MPI manually from the plugin, or if it is possible to configure the client to automatically load and start the MPI library? Just enabling the Multi-Core option in the ParaView settings does not seem to do the trick.</div><div><br></div><div>Regards,</div><div><br></div><div>Michael</div><br><br><div apple-content-edited="true">
