 When used, `--omni` will output profiling information for all subroutines, including rooflines, cache usage, register usage, and more, after the simulation is run.
 Adding this argument will moderately slow down the simulation and run the MFC executable several times.
 For this reason, it should only be used with case files with few timesteps.
