This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The Community Infrastructure for General Relativistic Magnetohydrodynamics (CIGR) collaboration will create a modern, scalable, and open, community toolkit and cyberinfrastructure for general relativistic magnetohydrodynamics (GRMHD). These tools will advance computational capabilities across the fields of numerical relativity and computational astrophysics and provide the collaborative infrastructure needed to accelerate the development of simulation codes able to accurately model grand challenge problems such as the coalescence of binary neutron stars, core-collapse supernovae, and gamma-ray bursts.CIGR includes four core thrusts that capitalize on accumulated experience with the Cactus framework, the scalable Carpet adaptive mesh refinement driver and the Whisky code for general relativistic hydrodynamics developed by the European Union Astrophysics Network: (i) providing a featureful toolkit for GRMHD that research groups can use and extend to build their own cutting edge production codes; (ii) providing an open code for GRMHD that integrates together components for general relativistic hydrodynamics, microphysical equations of state, magnetohydrodynamics, and radiation transport; (iii) developing new enabling cyberinfrastructure for numerical relativity, including highly reliable and optimized input/output, distributed storage and archives, data and simulation classification and provenance; and (iv) supporting these toolkits and tools on increasing large and complex computing environments such as the NSF's TeraGrid, DOE's LCF, and prepare for soon to arrive petascale and data-intensive environments such as NSF XD, Blue Waters and DataNet programs.

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。广义相对论磁流体动力学（CIGR）社区基础设施合作将为广义相对论磁流体动力学（GRMHD）创建一个现代的，可扩展的，开放的社区工具包和网络基础设施。这些工具将推进数值相对论和计算天体物理学领域的计算能力，并提供加速模拟代码开发所需的协作基础设施，这些代码能够准确地模拟重大挑战问题，如双中子星合并，核心坍缩超新星和伽马射线爆发。CIGR包括四个核心推力，利用Cactus框架积累的经验，由欧盟天体物理学网络开发的可扩展地毯自适应网格细化驱动程序和广义相对论流体动力学的威士忌代码：（i）为GRMHD提供一个功能齐全的工具包，研究小组可以使用和扩展该工具包，以构建自己的尖端生产代码;（ii）提供GRMHD的开放代码，其将广义相对论流体动力学、微观物理状态方程、（iii）为数值相对论开发新的使能网络基础设施，包括高度可靠和优化的输入/输出、分布式存储和档案、数据和模拟分类和出处;以及（iv）支持这些工具包和工具在日益增加的大型和复杂的计算环境中使用，例如NSF的TeraGrid，DOE的LCF，并为即将到来的千万亿次和数据密集型环境（如NSF XD、Blue沃茨和DataNet程序）做好准备。
