Funded through a grant from the National Science Foundation, LeMieux is a 3,000 processor system installed in the Pittsburg Supercomputing Center. It is capable of six teraflops (six trillion calculations per second), comparable to every person on Earth doing 1,000 calculations per second with a hand-held calculator. It is the most powerful system in the United States committed solely to public research and open to all science and engineering disciplines. It is used in diverse areas of research, including earthquake modeling, storm-scale weather forecasting, global climate change, and protein genomics.
