[QE-users] Problems to run QE in parallel

[Anibal Bezerra]

Dear Paulo,

Thanks a lot for the quick response!! Even using the command "mpirun" when
I complied QE using Intel's MPI, I got the same output.

I've started the compiling and making process from the beginning, after
uninstalled Intel's MPI, Mpich, installed Mpich's MPI again re-configured
QE. When I tried to run the silicon test, using both "mpiexec" and "mpirun"
I got replicated

Parallel version(MPI), running on    1 processors
MPI processes distributed on     1 nodes.

Is there anything else I could check for?

Thanks again!!

Anibal

If you link intel mpi, you should use the version of "mpirun" provided by
intel to run the parallel code
