You can not run them at the same time because it is exactly the influence of parallel load that you are trying to examine. So running the "serial" case of one core in parallel with other simulations...

The theoretical linear speedup can never be reached due to communication losses and parts in the code that can not be executed in parallel. So it is fastest to run as many cases at the same time as...
