Structural performance analysis of the NAS parallel benchmarks is usedto time code sections and specific classes of activity, such ascommunication or data movements. This technique is called {\emwhite-box benchmarking} because, similarly to white-boxmethodologies used in program testing, the programs are not treated asblack boxes. The timing methodology is portable, which isindispensable to make comparative benchmarking across differentcomputer systems. A combination of conditional compilation and codeinstrumentation is used to measure execution time related to differentaspects of application performance. This benchmarking methodology isproposed to help understand parallel application behaviour ondistributed-memory parallel platforms. |
