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

[Alexander G. Kvashnin]

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?
