When I was in graduate school, I was doing a lot of molecular dynamics simulations, but I did not have access to a lot of high-performance hardware. The math department had a 4-node Cray that was impossible to reserve time on, and the CS department had a 16-node Dell cluster that ran SGE and was decently reliable. When those resources ended up not being enough for my crazy array of tasks, I got resourceful and started gathering every single outdated CPU anyone anywhere on campus was getting rid of or had no use for, and built my own cluster in our lab. Before finishing my Ph.D. I had 12 SGI Indys, 8 PowerMac G3 6300s, 10 PowerMac G3 7600s, and 20+ Dell P3 towers in my "cluster". NetBSD is the only thing that made that possible.
