摘要

多轨InfiniBand网络为多核节点提供了改善带宽、提高可靠性和降低延迟的选项。SDSC的戈登超级计算机具有双轨InfiniBand 3d环面网络，用于评估使用多轨对性能的影响。该研究使用OSU微基准测试、P3FFT应用程序内核以及科学应用程序LAMMPS和AMBER进行。微基准测试证实了带宽和延迟性能方面的优势。在应用程序级别，性能改进取决于通信级别和配置文件。

Performance of Applications using Dual-Rail InfiniBand 3D Torus network on the Gordon Supercomputer

Multi-rail InfiniBand networks provide options to improve bandwidth, increase reliability, and lower latency for multi-core nodes. The Gordon supercomputer at SDSC, with its dual-rail InfiniBand 3-D torus network, is used to evaluate the performance impact of using multiple rails. The study was performed using the OSU micro-benchmarks, the P3FFT application kernel, and scientific applications LAMMPS and AMBER. The micro-benchmarks confirmed the bandwidth and latency performance benefits. At the application level, performance improvements depended on the communication level and profile.
