The Perfect Benchmarking effort. An acronym for PERFormance Evaluation by Cost-effective Transformations, Perfect was created at UIUC's Center for Supercomputing Research and Development (CSRD) in an effort to focus supercomputer performance evaluation at the applications level. Thirteen Perfect Benchmarks are Fortran programs drawn from a number of scientific and engineering research areas, including air pollution, fluid dynamics, seismic migration, quantum chromodynamics, and signal processing.
