Hello Haider,
<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>
<div class=""><br class="">
