Short post on one of the Intel blogs about benchmarking in HPC, and the need to focus (or refocus, as the author frames it) on total application performance
Want to improve application performance by 10x or 100x? Few HPC customers would say no. Yet in some cases, the promises of tremendous performance improvements from accelerators, attached processors, field-programmable gate arrays, and the like evaporate when total application performance is evaluated. Benchmarks that focus on kernel or even partial application performance provide incomplete picture with respect to the impact on total application benchmarking. While difficult, HPC customers should look to test total application performance.
