[Wien] MPI error

[leila mollabashi]

Dear all

The admin told me that I can use this line in the script
“/opt/exp_soft/local/generic/openmpi/4.1.0_gcc620/bin/mpiexec
/home/users/SOME_USER/app/my_mpi_app -o option 1 -in
/home/users/SOME_USER/path/to/input1  -o ./output1”

Would you please guide me about this line? Should I use “run_lapw -p”
insead of my_mpi_app? I don’t know what should I do instead of input1
and output1

Sincerely yours,

Leila
