[QE-users] QE Multi-GPU mpirun run command

[Vijeta Sharma]

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 ?
