The only parallelization approach used with this model is
The OpenMP computing approach will run the simulation in a number of threads. The user can specify this number of threads, which should not exceed the number of cores available on the machine.
PLEASE NOTE: Some computers have Hyper-Threading. The parallelized engines do not benefit from having this enabled. If a Hyper-Threaded computer has 4 cores and thus 8 threads, then the engines should be started with 4 threads.
