The HPCG Benchmark project is an effort to create a more relevant metric for ranking HPC systems than the High Performance LINPACK (HPL) benchmark, that is currently used by the TOP500 benchmark. The computational and data access patterns of HPL are no longer driving computer system designs in directions that are beneficial to many important scalable applications. HPCG is designed to exercise computational and data access patterns that more closely match a broad set of important applications, and to give incentive to computer system designers to invest in capabilities that will have impact on the collective performance of these applications.

The web page offers in-browser estimation of HPL perfomance on your system. Using a simple on-line form for system parameters and little bit of JavaScript the project offers a quick look at the potential configurations and corresponding performance numbers.

The TOP500 project was started in 1993 to provide a reliable basis for tracking and detecting trends in high-performance computing. Twice a year, a list of the sites operating the 500 most powerful computer systems is assembled and released.
