Is it possible to choose how much cores to use for N-Body Simulations? I didn't find anything on the forum

You will get that message until you download the nbody version. Apparently you have been running the GPU version thus far, and that is the only one it knows about.

By the way, BOINC makes it tricky to run both GPU and CPU apps from the same project. It may run into scheduling difficulties and not download one or the other. It is explained a bit on Einstein for a couple of cases, but there might be other conditions that cause it. I just use separate machines for the CPU and GPU apps in that case.
