Hardware acceleration of n-body simulations for galactic dynamics
(Affiliation: Rutgers Univ., Piscataway, NJ, USA, United StatesCorrespondence Address: Cook, Todd A.Rutgers Univ., Piscataway, NJ, USAUnited States, 1995)N-body methods are used to simulate the evolution and interaction of galaxies. These simulations are usually run on large-scale supercomputers or on very expensive full-custom hardare. This paper presents an alternative ...
