Hiroshi Ono contributed significant effort to the necessary benchmark candidate performance evaluation and scaling experiments for the SPEChpc 2021 Benchmark Suites. When further investigation was needed, he deepened his analysis and produced and interpreted hardware performance counter measurements to improve characterization of the benchmark candidates. The result of Hiroshi's investigation were very important for the selection of the benchmarks candidates. His analysis not only guided how much time the committee decided to allocate to certain candidates, but also identified unknown problems to be solved before launch. Hiroshi consistently performed these tasks for each kit over a two-year period.
