This award supports the acquisition of a 600-core, high-speed, large-memory computer cluster, "BlueSky", dedicated to supporting interdisciplinary research at the frontiers of gravitational physics, relativistic astrophysics, advanced high-performance computation, and scientific visualization in the Center for Computational Relativity and Gravitation at the Rochester Institute of Technology. Research will focus on some of the most extreme phenomena in the universe, where the strongest gravitational and magnetic fields interact with ultra-relativistic matter and high-energy radiation, that can only be studied through advanced, large-scale computation and visualization. These includes: (1) calculation of accurate gravitational wave signals from intermediate-mass ratio, highly-spinning black-hole binary inspirals and mergers, (2) the development of a highly accurate General Relativistic Magnetohydrodynamics code (which will be made publicly available through the Einstein Toolkit Consortium) for the modeling of neutron star mergers, accretion disks, and core-collapse supernovae, (3) calculation of electromagnetic signals from merging supermassive black holes at the centers of galaxies. Our research will use the enhanced speed of GPUs to generate fast and accurate hybrid gravitational signatures for LIGO data analysis.Research training will involve students across several programs and colleges at RIT. Visualizations will be used for enhancing the classroom experience of deaf and hard-of-hearing students in RIT's National Technical Institute for the Deaf and out-of-class educational activities. The cluster will be housed in the CCRG "Black-Hole" Lab. The laboratory is cooled using a state-of-the-art, in-rack, green-cooling solution provided by OptiCool Technologies. The laboratory has large glass walls along a high-traffic corridor, making the cluster and its operation highly visible to the public. Seeing "BlueSky" will stimulate interest in the instrument itself, gravitational physics, astrophysics in general, and green technologies.

该奖项支持采购600核高速大内存计算机集群“BlueSky”，致力于支持引力物理、相对论天体物理、先进高性能计算、科学可视化等前沿领域的跨学科研究。罗彻斯特理工学院计算相对论和引力中心。研究将集中在宇宙中一些最极端的现象，其中最强的引力场和磁场与超相对论物质和高能辐射相互作用，这些现象只能通过先进的大规模计算和可视化来研究。其中包括：（1）根据中间质量比、高旋转黑洞双星螺旋和合并计算精确的引力波信号，（2）开发高精度广义相对论磁流体动力学代码（将通过爱因斯坦工具包联盟）用于中子星合并、吸积盘和核心塌陷超新星的建模，（3）计算来自合并超大质量的电磁信号星系中心的黑洞。 我们的研究将利用 GPU 的增强速度来生成快速、准确的混合引力特征，用于 LIGO 数据分析。研究培训将涉及 RIT 多个项目和学院的学生。可视化将用于增强 RIT 国家聋人技术学院聋哑和听力障碍学生的课堂体验以及课外教育活动。该集群将安置在 CCRG“黑洞”实验室内。该实验室使用 OptiCool Technologies 提供的最先进的机架内绿色冷却解决方案进行冷却。该实验室沿着交通繁忙的走廊设有大型玻璃墙，使公众可以清楚地看到该集群及其运作。看到“BlueSky”将会激发人们对仪器本身、引力物理学、一般天体物理学和绿色技术的兴趣。
