The work to be carried out under this award will develop the needed infrastructure and apply it to study realistic compact binary systems that can give rise to gamma ray burst phenomena. To this end the required physics modules will be incorporated in a new infrastructure framework able to exploit the new generation of high performance computers. The implementations of this infrastructure will allow study of the system in depth, with the goal of predicting and interpreting aspects of observations of electromagnetic and gravitational waves. This work serves to advance computational and numerical techniques for an exciting scientific problem, as well as the creation and dissemination of advanced tools for distributed computing. The research to be carried out has as its goal to give an unprecedented description of possible (short) gamma ray burst systems and to develop a new computational model to efficiently utilize petascale computing. Finally, this study involves the training of postdoctoral researchers, graduate students, and undergraduates.

在该奖项下开展的工作将开发所需的基础设施，并将其应用于研究可能引起伽马射线爆发现象的实际紧凑双星系统。为此，所需的物理模块将被纳入一个新的基础设施框架，能够利用新一代的高性能计算机。该基础设施的实施将允许深入研究该系统，目标是预测和解释电磁波和引力波观测的各个方面。这项工作有助于推进一个令人兴奋的科学问题的计算和数值技术，以及分布式计算的先进工具的创建和传播。将要进行的研究的目标是对可能的（短）伽马射线爆发系统进行前所未有的描述，并开发一种新的计算模型，以有效地利用千万亿次计算。最后，本研究涉及博士后研究人员，研究生和本科生的培训。
