[Pw_forum] problem in MPI running of QE (16 processors)

[Eyvaz Isaev]

Well, again, we will appreciate, if you sign your e-mail providing your 
affiliation.

I do not think it is related to CPU numbers. 

Is a job you launched finished properly? 
 
Bests,
Eyvaz.

I create PBS task on supercomputer MIPT-60 where I write 


mpiexec ../../espresso-4.2.1/bin/pw.x -in graph.inp > output.opt

all other types of this line such as 

mpiexec -np 16 ../../espresso-4.2.1/bin/pw.x -in graph.inp > output.opt


doesn't work.
Maybe this number of processor too small for parallel calculation to QE?
