In this video from ISC 2018, John Bent and Jay Lofstead describe how the IO500 benchmark measures storage performance in HPC environments. The second IO500 list was revealed at ISC 2018 in Frankfurt, Germany.
Following the success of the Top500 in collecting and analyzing historical trends in supercomputer technology and evolution, the IO500 was created in 2017 and published its first list at SC17. The need for such an initiative has long been known within High Performance Computing; however, defining appropriate benchmarks had long been challenging. Despite this challenge, the community, after long and spirited discussion, finally reached consensus on a suite of benchmarks and a metric for resolving the scores into a single ranking.
The multi-fold goals of the benchmark suite are as follows:
Maximizing simplicity in running the benchmark suite
Encouraging complexity in tuning for performance
Allowing submitters to highlight their “hero run” performance numbers
Forcing submitters to simultaneously report performance for challenging IO patterns.
