[Pw_forum] QE GPU acceleration pool performance

[子逸 張]

Hello,

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?

thanks
