# This script takes its parameters from the same .ini file as io500 binary.

# The only parts of the script that may need to be modified are:
#  - setup_paths() to configure the binary locations and MPI parameters
#  - setup_directories() to create/tune the IOR/mdtest output directories

# Please visit https://vi4io.org/io500-info-creator/ to help generate the
