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.

根据该奖项进行的工作将开发所需的基础设施，并将其应用于研究现实的紧凑型二元系统，这些系统可以引起伽马射线爆发现象。为此，所需的物理模块将纳入一个可以探索新一代高性能计算机的新基础架构框架中。该基础设施的实现将允许深入研究系统，目的是预测和解释电磁和引力波观察的方面。这项工作用于推进令人兴奋的科学问题的计算和数值技术，以及用于分布式计算的高级工具的创建和传播。进行的研究的目的是对可能的（短）伽马射线爆发系统进行前所未有的描述，并开发出一种新的计算模型来有效利用Petascale计算。最后，这项研究涉及对博士后研究人员，研究生和本科生的培训。
