DescriptionHPL has been and still is the single most widely used benchmark for the HPC systems, even though there have been many criticisms. The most important criticism is that HPL measures only the peak floating point performance and its result has little correlation with real application performance. HPCG (and also HPGMG) have been proposed as either alternative or complimentary benchmarks. HPCG measures mainly the main memory bandwidth. In this BoF, we want to exchange opinions on what aspects of machines should be measured and how by these benchmarks, in particular, when used as the requirement for new machines.
