Abstract

私たちは、高並列TflpsマシンGRAPB-4を開発している。これは銀河や球状星団のようなたくきんの星でできている重力多体系のシミュレーション用の専用計算機である。世界に先駆けてTflopsの実効性能を達成することを目指している。GRAPE-4のために二つのカスタムLSI、粒子の加速度とその時間微分を計算するHARPチップと粒子の位置と速度を予測するPROMETHEUSチップ開発した。GRAPE-4ではPROMETHEUSチップを約40個、HARPチップを約2000個使用する。本稿ではGRAPE-4プロジェクトの概要を説明する。We are developing GRAPE-4, the teraflops machine for gravitational many-body simulations. Gravitational many-body systems, such as galaxies and globular clusters, consists of a lot of stars, which interact each other trough gravitational force. We developed two custom LSIs, HARP chip and PROMETHEUS chip. HARP chip calculates force and time derivative of force, while PROMETHUS chip performs predictor calculations of positions and velocities of particles. We use about 2000 HARP chips and about 40 PROMETHEUS chips. In the present paper, we briefly describe the GRAPE-4 project.
