[QE-users] Bad scaling on GPU version QE

[JING YANG]

Hi,
    I am trying to test the scaling of GPU version of QE recently. I found
out the computational time scaling of the GPU version is very bad. Is there
any unique flags or keywords I don't know about the GPU version? I am using
gcc-6.2.0, openmpi-1/8/4, craype-accel-nvidia35. I know it is not the
recommended set up, but I guess if I can compile it successfully, then it
should work normally.

Thanks,
Jing
