[QE-users] A strange error when using GPU accelerated ph.x

[lq1998]

Dear developers and users,


I tried to run GPU version of QE for electron phonon coupling calculation on an a100 card. The structure relaxation and self-consistent calculation are successful. However, when I did phonon calculation, my job crashed with a strange error:

I am not an expert of coding, but it seems like the line 325 wasn't recognized, which is fairly strange. I don't know how to solve this problem, and I am glad if anyone can help me.


Yours,
