I see that you didn't bother to check out the software proposed soon
after you asked your question. If you don't check out potential
answers because you doubt they will work, why should anyone bother to
reply to you?

The problem you have is a common issue in university environments, and
the common solution is a script that accurately figures out
long-running cpu-intensive programs and nices/kills them. I first ran
into such a thing in, oh, 1992? It's not rocket science.
