Abstract:
In this paper we describe the current status of the GRAPE-6 project to
develop a special-purpose computer with a peak speed exceeding 100
Tflops for the simulation of astrophysical N-body problems. One of
the main targets of the GRAPE-6 project is the simulation of dense
stellar systems. In this paper, therefore, we overview the basic
algorithms we use for the simulation of dense stellar systems and
their characteristics. We then describe how we designed GRAPE hardwares to
meet the requirements of these algorithms. GRAPE-6 will be completed
by the year 2001. As an example of what science can be done on
GRAPE-6, we describe our work on the galactic center with massive
black holes performed on GRAPE-4, the predecessor of GRAPE-6.
