Dear Vijeta,
Based on QE error convention codes in mp_world.f90, I think this error is
CUDA_ERROR_UNSUPPORTED_PTX_VERSION. It can come from an outdated driver, or not
passing the right flags to NVCC ("-arch sm_70") or PGI (“-gpu=cc70”). Are you
sure that your build really runs with 1 GPU ? In
Hi Robert,
I think it's an issue with PGI in NVHPC 22.3. Please use NVHPC 21.9 instead
(PGI compiler).
Normally the configure script should catch it and prevent using NVHPC 22.3,
unfortunately the check has been introduced only after QE 7.0.
Best,
Louis

Hi Jonathan,
Thanks for your message and apologies for the late reply, as Paolo mentioned,
the GPU version should never be slower than the CPU one except if it calls
routines which are not implemented (fortunately the one you talked about has
been implemented recently).
