</div>Your laptop probably doesn't have enough memory for that.<br></blockquote><div><br></div><div>Yes, I tried it just a while ago and this is happened I think. (Just to confirm, I have put the error message for this case at the very end of this reply.*)<br>

Can you try running on the cluster with one MPI rank per node? We<br>
should rule out simple out-of-memory problems, confirm that the code<br>
executes correctly with MPICH, and finally figure out why it fails with<br>
Open MPI (assuming that the previous hunch was correct).<br>
<br>
</blockquote></div><br></div><div class="gmail_extra">I'm sorry but I'm a complete beginner with MPI and clusters; so what does one MPI rank per node means and what should I do to do that ? My guess is that I set one core per node and use multiple nodes in my job script file ? Or do I need to do something in the petsc code ? <br>
