MRI: Acquisition of two special-purpose computers for simulation of the galactic center environment

该项目是为了获得一对先进的专用计算机，用于银河系中心动力学和演化的N体模拟。这些计算机被称为GRAPE-6Pros，包含大规模并行管道，可以以每秒约1万亿次浮点运算的速度计算多达100万个粒子之间的平方反比引力。结合RIT最近开发的复杂的N体代码，该代码有效地整合了超大质量黑洞附近的恒星轨道，GRAPE计算机将使RIT的研究人员和学生能够对银河系中心的核星星集群进行迄今为止最复杂的模拟。

This project is for the acquisition of a pair of advanced, special-purpose computers to be used in N-body simulations of the dynamics and evolution of the center of the Milky Way galaxy. The computers, called GRAPE-6Pros, contain massively parallel pipelines that can compute inverse-square gravitational forces between as many as one million particles at a speed of approximately 1 trillion floating point operations per second. Combined with sophisticated N-body code that was recently developed at RIT, which efficiently integrates stellar orbits near the supermassive black hole, the GRAPE computers will enable researchers and students at RIT to carry out the most sophisticated simulations to date of the nuclear star cluster at the center of the Milky Way galaxy.
