Next Generation Parallel Computing Infrastructure for Numerical Relativity

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。该奖项支持在下一代超级计算机上开发有效求解爱因斯坦广义相对论方程所需的软件基础设施的研究。这种能力将被用于演化包含两个质量不等的黑洞的系统，这是一个重要的潜在引力波来源，可以被地面和太空探测器探测到，比如LIGO和LISA。双黑洞的计算机模拟提供了引力波形，可以用来搜索较弱的信号，而不是没有这些信息。新的超级计算机通过将每个CPU的核心数量增加到数十甚至数百个来实现速度突破。为今天的计算机设计的计算机代码必须重新设计，以最大限度地利用新的体系结构。这个项目是RIT为广义相对论开发新的、高效的、高精度的数值算法的持续努力的一部分。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). This award supports research to develop software infrastructure required to efficiently solve the Einstein Equations of General Relativity on the next generation of supercomputers. This capability will then be exploited to evolve systems containing two black holes of unequal mass, an important potential source of gravitational waves detectable by ground-based and space-based detectors such as LIGO and LISA. Computer simulations of binary black holes provide gravitational waveforms that can be used to search for weaker signals than could be found without this information. The new supercomputers achieve speed breakthroughs by increasing the number of cores per CPU to tens or even hundreds. Computer codes designed for today's computers must be redesigned to take maximum advantage of the new architechture. This project is part of an ongoing effort at RIT to develop new, highly efficient, high-accuracy numerical algorithms for General Relativity.
