Duy Le is write, you should take a look to the man of mpiexec.<br>
It is "mpiexec -n" !<br>
Have you tried to run small mpi program first in order to check
whether your machine is well configured?<br>

<pre wrap="">You can use:
mpiexec --help
or
man mpiexec
to see how to have correct command

Maybe this number of processor too small for parallel calculation to QE?

Dear Alexander,
How do you run a job? You should launch a command like (some parameters
are omitted)
mpirun -np 16 -maxtime 30 ./pw.x < scf.in >scf.out

Subject: [Pw_forum] problem in MPI running of QE (16 processors)
Hello,
I have some problem when I ran parallel version of QE (16 procs), I saw
next line in output file
Parallel version (MPI), running on 1 processors
And it works using only 1 processor, but there is MPI version.
Help me please in my problem
Thank you!
