N-Body Simulations: Computing
Scientific paper
In theoretical astrophysics, computer simulations have been extensively used to perform experiments on astronomical objects such as stars, galaxies, and even the whole universe. Such numerical experiments have been performed on general-purpose computers. However, advances in silicon VLSI technology make it practical for astrophysicists to build customised computing devices to solve their own problems. As an example, the authors give a brief overview of their own project, known as "GRAPE". The aim of the GRAPE project is to develop hardware that can run astrophysical N-body simulations much faster than high-performance general-purpose computers. GRAPE is an acronym for gravity pipe. GRAPE-4 is the world's fastest computer for scientific calculation. The authors describe the results of simulations on GRAPE-4 and discuss the future of the GRAPE project.
