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.
