<div class="moz-signature">Dear QE developers, <br>
I have downloaded via git the version 6.2 of Quantum Espresso to
run GW-approximation calculations with a test case for silicon. My
version is compiled with intel suite and mpi compilers as shown in
the file qe_parallel_cx1.pbs compressed in the attached file.<br>
<br>
Unfortunately, I am getting the following MPI-related error at the
end of the execution of the pw4gww.x command as you might see in
the file ./pw4gww/log.out:<br>
<br>
<i>rank 19 in job 1 cx1-132-1-7_41723 caused collective abort
of all ranks</i><i><br>
</i><i> exit status of rank 19: return code 0</i><i><br>
</i><i>rank 16 in job 1 cx1-132-1-7_41723 caused collective
abort of all ranks</i><i><br>
</i><i> exit status of rank 16: return code 0</i><i><br>
</i><i>rank 10 in job 1 cx1-132-1-7_41723 caused collective
abort of all ranks</i><i><br>
</i><i> exit status of rank 10: return code 0</i><br>
<br>
As the serial version runs fine and I find with the same error in
a different unix machine, I wonder if this problem has to do with
a possible bug in the code or a I should recompile the code with
different options or compilers. A quick test on your side could
shed some light on this problem.<br>
<br>
In addition, the execution of the serial version of the command
gww.x is taking a long time, looking to me that is hanging. Is
this normal? Or should I recompile the code with different
compilers?<br>
<br>
Best regards,<br>
