非真空合并中的保真度和可扩展性
Towards fidelity and scalability in non-vacuum mergers
摘要：
本文利用两种不同的广义相对论流体力学（GRHD）分布式自适应网格程序，研究了两种双星中子星基准组态的演化。一个代码，HAD，多年来一直被用来研究合并紧凑的对象二进制文件，而一个新的代码，MHDuet，最近开发的经验与旧的一个以及一些新的功能，可扩展性的改进。因此，我们检查每个的性能，特别关注未来的要求，提取非真空双星的引力波签名。
英文摘要：
We study the evolution of two fiducial configurations for binary neutron stars using two different general relativistic hydrodynamics(GRHD), distributed adaptive mesh codes. One code, HAD, has for many years been used to study mergers of compact object binaries, while a new code, MHDuet, has been recently developed with the experience gained with the older one as well as several novel features for scalability improvements. As such, we examine the performance of each, placing particular focus on future requirements for the extraction of gravitational wave signatures of non-vacuum binaries.
