You can estimate a needed performance capacity by analyzing your computer efficiency for a single simulation run without any experimenter use. Each additional simulation run needs roughly the same resources as a single model run. You will notice that your system has much more available CPU cores than needed Memory. You can restrict in Experimenter setup, how many cores you allow to use simultaneously. Typically you start with a small number of cores like one or two. If there are still resources available beside CPU cores you can increase the number of CPU cores by one in each new test. If your system runs by high performance with a power of 80 percent for a longer time, you will notice that you hear your cooling system components are getting louder. This will tell you that your system is going to reduce its efficiency. You have to find a balance of low thermal exhaust and high performance power, because your system can switch the core cycle frequency automatically to reduce the efficiency to be near 30% of maximum power. If you can keep the core frequency high before it shuts lower automatically you win. It depends much on the current actual room temperature which will rise by long simulation runs. Your system will heat up your environment.
