High Performance N-Body Computing

我们在日本方面，正在制造一台Tera触发器，用于解决引力多体问题。该项目的目的是与英国集团合作，为我们的专用Tera触发器机器制作软件。我们1993财政年度的项目摘要如下：1.太极和八洲已经完成了一个新的电路板的设计Hermite积分器，这是所谓的HARP-3。该板的副本将被转移到天文研究所，剑桥大学，直到1994年6月底。Aarseth将使用该板为我们的Tera flops机器开发他的Hermite代码。2. Aarseth从1994年3月5日到3月17日住在东京大学。他成功地将他的Hermite码实现到我们的测试机HARP-2中，并证明了Hermite码对于整合碰撞N体系统的演化是有用的。3.八须、船人和稻垣访问了剑桥大学天文研究所，并与英国小组进行了讨论。我们现在正在开发工具来处理二进制演化，星星捕获，以及我们的N体代码中的恒星-星星碰撞。

We, in Japan side, are making a Tera flops machine for gravitational many body problems. The purpose of this project is to make softwares for our special-purpose Tera flops machines under a cooperation with the UK group. The summary of our 1993 fiscal year project is as follows:1.Taiji and Hachisu have finished designing a new board for Hermite integrator, which is called HARP-3. A copy of the board will be transferred into Institute of Astronomy, Cambridge University until the end of June, 1994. Aarseth will use the board to develop his Hermite code for our Tera flops machine.2.Aarseth has stayed at the University of Tokyo from 5th of March to 17th of March, 1994. He succeeded in implementing his Hermite code into our test machine, HARP-2, and proved that the Hermite code is useful to integrate the evolution of collisional N-body systems.3.Hachisu, Funato, and Inagaki visited the Institute of Astronomy, Cambridge University and discussed with the UK group. We are now developing tools to treat binary evolutions, star captures, and star-star collisions in our N-body code.
