We have "microbenchmarks" and "paper and pencil" benchmarks and "pseudo-application" benchmarks and "application benchmarks" and "workload" benchmarks, and it is possible to think of other categories. This presentation will review some of the basic philosophical differences across benchmarking communities, and will attempt to categorize benchmarking efforts in terms of their underlying philosophy of performance modelling, their intended customers, their intended goals, and their unintended side effects. The talk will conclude with a proposal for a minimalist constitutive framework for characterizing HPC systems, as a possible adjunct to, or replacement for, the current LINPACK-based TOP500 list.
