Dear Filippo,
Thanks. I have downloaded the AUSURF112 example and test run, but it waits for
input for very long time such as 12 hours,
zgdeng@NVGPU-P2807:~/QE520/espresso-5.2.0/bin> export I_MPI_PIN=on
zgdeng@NVGPU-P2807:~/QE520/espresso-5.2.0/bin> export
MPI_PIN_PROCESSOR_LIST=all:map=bunch
zgdeng@NVGPU-P2807:~/QE520/espresso-5.2.0/bin> mpirun -genvall -np 8 ./pw.x
~/QE520/AUSURF112/ausurf.in ~/QE520/AUSURF112/ausurf.out

Parallel version (MPI), running on 8 processors
R & G space division: proc/nbgrp/npool/nimage = 8
Waiting for input...
I run top on other terminal and found 8 instances of pw.x running, is this
normal ? My CPUs are two Xeon 6 cores at 2.6 GHz.
Thanks,

it will work out of the box if you run mpirun correctly. You need to play with
the scripts. Anyway, they are too small to show any sort of acceleration and
some exploit functionalities of the code that are not GPU accelerated.
If you have a real test case instead of an example I suggest to start directly
with it. If you have no experience with the code, use CPU only first.
