Stellar Dynamics on 200 Tflops Special-Purpose Computers
"... . We overview the GRAPE-6 project, a follow-up of the teraflops GRAPE-4 project. GRAPE-6 will be completed by 1999-2000 and its planned peak speed is 200 Tflops. Its architecture will be largely similar to that of GRAPE-4, which is a specialized hardware to calculate the gravitational interaction be ..."

between particles. The improvement in the speed will come mainly from the advance in the silicon semiconductor technology. GRAPE-6 will enable us to directly simulate the evolution of star clusters with up to 1 million stars. 1. Introduction In 1988, we started the development of special-purpose
High-Performance Special-Purpose Computers in Science
"... The next decade will be an exciting time for computational physicists. After 50 years of being forced to use standardized commercial equipment, it will finally become relatively straightforward to adapt one's computing tools to one's own needs. The breakthrough that opens this new era is t ..."

Acceleration of fast multipole method using special-purpose computer GRAPE
- International Journal of High Performance Computing Applications
, 2008
"... We have implemented the fast multipole method (FMM) on a special-purpose computer GRAPE (GRAvity piPE). The FMM is one of the fastest approximate algorithms to calculate forces among particles. Its calculation cost scales as O(N), while the naive algorithm scales as O(N2). Here, N is the number of p ..."
