Collisional Stellar Dynamics, Gas Dynamics and Special Purpose Computing
R. Spurzem, J. Makino, T. Fukushige +6
Challenging stellar dynamical problems, such as the study of gravothermal oscillations in star clusters, have in the past initiated the very successful building of GRAPE special pu…
Structure of Dark Matter Halos From Hierarchical Clustering: II. Universality and Self-Similarity in Cluster-Sized Halos
Toshiyuki Fukushige, Junichiro Makino
We investigate the structure of the dark matter halo formed in three different cold dark matter scenarios. We performed N-body simulations of formation of 13 cluster-sized halos. I…
7.0/Mflops Astrophysical N-Body Simulation with Treecode on GRAPE-5
Atsushi Kawai, Toshiyuki Fukushige, Junichiro Makino
As an entry for the 1999 Gordon Bell price/performance prize, we report an astrophysical N-body simulation performed with a treecode on GRAPE-5 (Gravity Pipe 5) system, a special-p…
High-Performance Special-Purpose Computers in Science
Toshiyuki Fukushige, Piet Hut, Jun Makino
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 st…
