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 It can come from an outdated driver, or not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 that case, it might be that
the 2 GPUs have a different architecture (then use something like
“-gpu=cc70,cc80” to specify multiple archs).
Best,
Louis

Subject: [QE-users] QE Multi-GPU mpirun run command
External email: Use caution opening links or attachments
Dear QE researchers,
I am running QE-GPU with the following command for 2 GPU (1 process each GPU):
mpirun -np 2 pw.x -inp data.in
But it is giving error of
*** error in Message Passing (mp) module ***
*** error code: 9422
*** error in Message Passing (mp) module ***
*** error code: 9422
Can anyone provide me the correct mpirun command to run QE on multi-GPU ?
