[Pw_forum] Issue while executing QE-5.0 GPU

[Filippo Spiga]

Dear Nisha,

the error as it is reported in your email does not give much details honestly. Make sure --with-gpu-arch=sm_20 for your GPU.

If it runs properly for small system on your machine but it dies for big systems then check the normal not-accelerated version of QE can run. If it runs and the problem appears only when GPU is turned on then we can try to investigate further.
