Hello Leo, 

if your model consists of only 5000 cells, then increasing the number of cores might not help since you will effectively be spending most of your computation time communicating the solution between cores/partitions.

Each GB of RAM should be able to handle in the order of 10^5 cells. So it is likely that you would not see much improvement by parallelizing this simulation.
