Hi Haider,
<div class=""><br class="">
</div>
<div class="">I would suggest, if you are not already doing that, to build and install mpich yourself in your home (which hopefully resides on a network file system mounted on all the machines of the cluster). Please use the latest stable tarball distribution
(you can find it at: <a href="https://www.mpich.org/downloads/" class="">https://www.mpich.org/downloads/</a>). In the README you can find instructions on how to configure and build the library. Don’t forget to add your installation path to the PATH environment
or else you will still be running with the system installation instead of your local one.</div>
<div class=""><br class="">
</div>
<div class="">Best,</div>
<div class="">Giuseppe</div>

<div class=""><br class="">
</div>
<div class="">Are you compiling mpich and installing it in a global path accessible to all machines or you are using local installations? The missing symbol is a fortran symbol. The fact it is not there can mean mpich was not compiled with fortran support while
your application is a fortran code. The fact that it works for a certain number of processes might mean some machine do have fortran support while other machines don’t.</div>
<div class=""><br class="">
</div>
<div class="">Can you provide some additional information about your cluster configuration? The MPICH version you are running and how you are configuring it?</div>
