What is it called when i want to simulate a system and want to run it many times?

Question

So i have this project where i have to simulate a gaming situation. My ideas for how to do this are to do it in Unity, XNA or just textbased in VS without any extra tools. One thing i need is the possibility that it can run the test really fast and i thereby want to find some information about how good the different environments would be at solving this. For that i either need some help finding this information or at the very least a name for what its called when you want to simulate a situation really fast.

Answer 1

Based on your description, you want to Stress test the system.

Checkout this article that lists various tools and describes the principles behind stress-testing a PC by simulating a gaming workload (which is exactly what you are looking for).
