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.

这个项目是为了获得一对先进的专用计算机，用于模拟银河系中心的动力学和演化。这些被称为GRAPE-6Pros的计算机包含大量并行管道，可以以每秒大约1万亿次浮点运算的速度计算多达100万个粒子之间的引力的平方反比。结合RIT最近开发的复杂的n体代码，它有效地集成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团进行迄今为止最复杂的模拟。
