Many tools and libraries employ Hardware Performance Monitoring (HPM) on modern processors, and using this data for performance assessment and as a starting point for code optimizations is very popular. However, such data is only useful if it is interpreted with care, and if the right metrics are chosen for the right purpose. The authors demonstrate the sensible use of hardware performance counters in the context of a structured performance engineering approach for applications in computational science.
