SPH Simulations with Reconfigurable Hardware Accelerator

Autor: Nakasato, N., Hamada, T., Fukushige, T.

We present a novel approach to accelerate astrophysical hydrodynamical simulations. In astrophysical many-body simulations, GRAPE (GRAvity piPE) system has been widely used by many researchers. However, in the GRAPE systems, its function is completel

Collisional Stellar Dynamics, Gas Dynamics and Special Purpose Computing

Autor: Spurzem, R., Makino, J., Fukushige, T., Lienhart, G., Kugel, A., Maenner, R., Wetzstein, M., Burkert, A., Naab, T.

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 purpose computers. It is discussed, that present day tasks such as the f

The Time Scale of Escape from Star Clusters

Autor: Fukushige, T., Heggie, D. C.

Publikováno v: Mon.Not.Roy.Astron.Soc. 318 (2000) 753

In this paper a cluster is modelled as a smooth potential (due to the cluster stars) plus the steady tidal field of the Galaxy. In this model there is a minimum energy below which stars cannot escape. Above this energy, however, the time scale on whi

The PCI Interface for GRAPE Systems: PCI-HIB

Autor: Kawai, A., Fukushige, T., Taiji, M., Makino, J., Sugimoto, D.

We developed a PCI interface for GRAPE systems. GRAPE(GRAvity piPE) is a special-purpose computer for gravitational N-body simulations. A GRAPE system consists of GRAPE processor boards and a host computer. GRAPE processors perform the calculation of
