[QE-users] MPI error in pw.x

The problem seems to crop up when a minimum of 8 processors are used. As a quick and easily accessible test, I tried it on example08 of the Wannier90 examples with the following command;
mpirun -np 8 pw.x -i iron.scf > scf.out
and the same problem occurred. I am using PWSCF v.6.3 using the Intel parallel studio 2016 suite. PW was built using all intel compilers, intel MPI and mkl.
Many thanks,
Alex

If it is not a problem of your compiler or mpi libraries, it can only be
the usual problem of irreproducibility of results on different processors.
In order to figure out this, one needs as a strict minimum some information
on which exact version exhibits the problem, under which exact
circumstances (e.g. mpirun -np ... ) and an input that can be run in a
reasonable amount of time on a reasonably small machine.
