Early Benchmark Efforts
Early 1970’s scientific Fortran codes that made heavy use of floating point codes.
Very long execution times.
Livermore Lops - Livermore Fortran Kernels
- http://www.netlib.org/benchmark/livermore
- 24 (14) DO loops
- Originated the use of Mflop/s for performance.
- Reported variety of statistics in an effort to boil down.
- Arithmetic, Harmonic, Geometric mean, . . .
- Exposed many issues in benchmarking
- Small changes in code making big differences in performance.
