<br>
I am trying to run QE 5.4.0 with MPI parallelization on a mid-size<br>
cluster. I successfully tested the installation using 8 processes<br>
distributed on 2 nodes, so communication across nodes is not a problem.<br>
When I, however, run the same calculation on 64 cores, I am getting the<br>
following error messages in the stdout:<br>
<br>
<br>
iteration # 1 ecut= 30.00 Ry beta=0.70<br>

The cluster queues stderr shows that some MPI processes exited:<br>

The cluster is running some sort of Sun Grid Engine and I used intel<br>
MPI. I see no other error messages. Could you give me a hint how to<br>
debug this further? Verbosity is already 'high'.<br>
<br>
Thank you very much and best regards,<br>
