[QE-users] Issue with MPIRUN when executing pw.x script

[Pietro Delugas]

Dear Aziz

is seems to be the typical  behavior  that usually occurs when part of 
the code was compiled as serial --without __MPI defined in make.inc, but 
finally linked with mpif90. Something could have gone wrong when you 
executed the configure script.

I would

1) run configure again

2) check inside make.inc that -D__MPI is included in the DFLAGS string

3) recompile again

I hope that it works

regards  -  Pietro
