The growing size of data center and HPC networks pose unprecedented requirements on the scalability of simulation infrastructure. The ability to simulate such large-scale interconnects on a simple PC would facilitate research efforts. Unfortunately, as we first show in this work, existing shared-memory packet-level simulators do not scale to the sizes of the largest networks considered today. We then illustrate a feasibility analysis and a set of enhancements that enable a simple packet-level htsim simulator to scale to the unprecedented simulation sizes on a single PC. Our code is available online and can be used to design novel schemes in the coming era of omnipresent data centers and HPC clusters.

不断增长的数据中心和HPC网络规模对模拟基础架构的可扩展性提出了前所未有的要求。在简单的PC上模拟这种大规模互连的能力将有助于研究工作。不幸的是，正如我们在这项工作中首先展示的那样，现有的共享内存数据包级模拟器无法扩展到当今考虑的最大网络的规模。然后，我们说明了可行性分析和一组增强功能，这些功能和增强功能使一个简单的数据包级htsim仿真器能够在单个PC上扩展到前所未有的仿真尺寸。我们的代码可在线获得，并可用于在无所不在的数据中心和HPC集群的时代设计新颖的方案。
