[Pw_forum] QE-GPU 14.10.0 with intel compilers

[Dr. NG Siu Pang]

Dear Filippo,

Apologies for my mistake, my input command was incorrect, now it runs with
mpirun -genvall -np 8 ./pw.x -inp ~/QE520/AUSURF112/ausurf.in |tee ~/QE520/AUSURF112/ausurf.out

I see it takes about 26G of RAM and 8 instants of pw.x is running with 'top'.

However, I check with 'nvidia-smi',
