I have some questions about the GPU version of QE.
In my testcases, GPU version of QE didn't have good performance in acceleration.
One of the testcases even run over 4 hours without finishing.
However in CPU version, it just took 33 minutes. (under 16 processes)
I want to know that is this a standard situation?
or it is related to input file?
