[Q-e-developers] Problem with trunk and intel-MPI

Hello,

I think any nscf calculation (after a scf to get density) should lead to
this. Any call to read_file() so also post processing etc.

We tested:
1) ifort (IFORT) 17.0.3 20170404 + Intel(R) MPI Library for Linux* OS,
Version 2017 Update 2 Build 20170125

2) ifort (IFORT) 16.0.0 20150815 + Intel(R) MPI Library for Linux* OS,
Version 5.1.1 Build 20150715 (build id: 12269)

3) ifort (IFORT) 16.0.0 20150815+  mvapich2 v 3.1.4

What work:

1) GCC 4.9.2 + openmpi 1.8.4

2) intel 2017 and 2016 + openmpi 2.0.2

Best,

Samuel
