We developed a new special-purpose computer, GRAPE-8, designed to be used with Particle-Particle Particle Tree method, which is a method to handle both collisionless and collisional systems efficiently. The processor chip of GRAPE-8 achieved the performance per watt of 40 Gflops/W, which is more than 30 times better than those of the latest general-purpose microprocessors. The performance per watt of the total system is around 6Gflops/W, nearly an order of magnitude better than that of usual PC clusters. Thus, we succeeded to reduce the cost of electricity for large-scale astrophysical simulations.

我们开发了一台新的专用计算机GRAPE-8，它被设计用于粒子-粒子粒子树方法，这是一种有效地处理无碰撞和碰撞系统的方法。GRAPE-8处理器芯片达到了40Gflops/W的性能功耗比，比最新的通用微处理器高出30多倍。整个系统的性能功耗比约为6Gflops/W，比通常的PC集群高出近一个数量级。因此，我们成功地降低了大规模天体物理模拟的电力成本。
