GRAPE project for a dedicated tera-flops computer

We are constructing a one tera-flops machine dedicated to astronomical many-body problems. It consists of parallelized GRAPE machines connected to a host workstation. The GRAPE machines only calculate forces between particles in the system by pipeline architecture. We designed and fabricated LSI chips for it, and about 2000 chips are being connected in parallel. The machine will be in operation by summer of 1995. General concept and features of the machine, mode of parallelization, and their merits are discussed in addition to scientific objectives of the project.<
