How to set io500_find_mpi to True for io500 C app version ?

[pvaldria]

I had to set io500_find_mpi to True in the io500.sh script to avoid getting this error: “io500_find_mpi: unbound variable” , but I don’t know if there is a different way to set the value for the C-version using config.ini file, can someone share how to pass that value for the C-app version?

function setup_find {
io500_find_mpi="True"

Revised answer: you need to set: external-mpi-args to e.g., "mpiexec -np 4" Note that nproc cannot be inferred to be on the correct position.
