Stampede2 Knights Landing (KNL) systems are available for global distribution through the Texas Advanced Computing Center’s Legacy Computing Program, and to HPC Ecosystems Project partners. To ensure the novel KNL architecture is fit for purpose for sites contemplating adopting the legacy systems, this publication provides a brief performance reference guide for prospective adopters. Benchmark tests were conducted to evaluate Stampede2’s KNL processors on modern workloads to help inform prospective adoption decisions. It was concluded that the Stampede2 KNL processors remain particularly suitable for applications that benefit from good memory bandwidth, but that multi-node use is only feasible if high-performance networking is also available.FulltextenHPC Ecosystems ProjectLegacy ComputingResource-Constrained EnvironmentsXeon Phi Knights LandingBenchmarksKnights Landing systemsConference PresentationN/A
