Hello, I am trying to do BSE calculation, on preceding step of the calculation, I faced a bug when I perform a low scaling, single shot GW calculation: G0W0R with ALGO=G0W0R ‘internal error in: GG_base.F at line: 204
internal error in GDES_SET: NRPLWV not dividable by cores 6032 52 313651

Hi dinesh_acharya1,

thanks a lot for reporting a bug. With your input, I can also reproduce it in the current 6.4.3 version.

The actual problem is that you have set NCORE > 1, which is not supported for GW calculations. If you comment out that line in your INCAR, the BUG message will disappear.

Of course, the code should warn you about the issue and exit gracefully instead of producing this bug. It does print a warning if GW is started with NCORE > 1 if more than one k points are used. But it should do so even if you use the gamma-only version. We will fix this in the next release and I thank you again for bringing it to our attention.

As a side note, I noticed that your ENCUT is set to a value lower than the highest EMIN value in your POTCAR. This is probably not a good idea.

Cheers, Michael
