A GRAPE-6a supercomputer board, running at 120 Gflops peak, powers this site's N-body simulations. It was provided by astrophysicist Prof. Jun Makino of Tokyo University, lead designer of the GRAPE hardware and six-time winner of the annual international Gordon Bell Prize competition for fastest supercomputer performance.
For over 40 years Dr. Sverre Aarseth of Cambridge University has pioneered the field of direct N-body simulations. His 2003 book, the work of a craftsman, describes a lifetime of research, his codes series NBODY1 through NBODY6, and a history of N-body simulation techniques and scientific applications. His software with source code is freely available. NBODY4 has been tested and refined for over 10 years with GRAPE-family hardware.
