SUMMARY:Latency and Bandwidth Microbenchmarks of US Department of Energy S
 ystems in the June 2023 Top 500 List
DESCRIPTION:Christopher M. Siefert, Carl Pearson, and Stephen L. Olivier (
 Sandia National Laboratories); Andrey Prokopenko (Oak Ridge National Labor
 atory (ORNL)); and Jonathan Hu and Timothy J. Fuller (Sandia National Labo
 ratories)\n\nAs a rule, Top 500 class supercomputers are extensively bench
 marked as part of their acceptance testing process. However, barring publi
 cly posted LINPACK / HPCG results, most benchmark results are often inacce
 ssible outside the hosting institution. Moreover, these higher level bench
 marks do not provide easy answers to common questions such as “What is the
  realizable memory bandwidth?” or “What is the launch latency on the accel
 erator?” To partially address these issues, we executed selected single-no
 de micro-benchmarks — focused on latencies and memory bandwidth — on every
  US Department of Energy system above rank 150 of the June 2023 Top 500 li
 st, excepting NERSC’s Cori and ORNL’s Frontier TDS (now decommissioned or 
 repurposed). We hope to provide an easy “first stop” reference for users o
 f current Top 500 systems and inspire users and administrators of other To
 p 500 systems to similarly compile and make available benchmark results fo
 r their systems.\n\nTag: Modeling and Simulation, Performance Measurement,
