Dear Mohaddeseh et co,
Just a note: I used to have such problems when I had compiled with
MKL-ScaLAPACK of old version, indeed around 11.1, when I ran with more
than four cores. I think I managed to run when I disabled ScaLAPACK. Of
course this might be fully unrelated to your problem.
Greetings from Lappeenranta,

This is not a QE problem: the fortran code knows nothing about nodes and cores.
It's the software setup for parallel execution on your machine that has a
problem.

Dear all,
I have recently installed PWscf (version 5.1) on our cluster (4 nodes, 32
cores).
Ifort & mkl version 11.1 has been installed.
When I run pw.x command on every node individually, for both the following
command, it will work properly.
1- /opt/exp_soft/espresso-5.1/bin/pw.x -in scf.in
2- mpirun -n 4 /opt/exp_soft/espresso-5.1/bin/pw.x -in scf.in
However, when I use the following command (again for each of them, separately),
3- mpirun -n 8 /opt/exp_soft/espresso-5.1/bin/pw.x -in scf.in
it gives me such an error:
[cluster:14752] *** Process received signal ***
[cluster:14752] Signal: Segmentation fault (11)

--------------------------------------------------------------------------
mpirun noticed that process rank 4 with PID 14752 on node cluster.khayam.local
exited on signal 11 (Segmentation fault).
--------------------------------------------------------------------------
This error also exists when I use all the node with each other in parallel mode
(using the following command):
4- mpirun -n 32 -hostfile testhost /opt/exp_soft/espresso-5.1/bin/pw.x -in
scf.in
The error:
[cluster:14838] *** Process received signal ***

--------------------------------------------------------------------------
mpirun noticed that process rank 24 with PID 14838 on node cluster.khayam.local

Any help will be appreciated.
