[This post was co-written by Everett Phillips and Massimiliano Fatica.] The High Performance Conjugate Gradient Benchmark (HPCG) is a new benchmark intended to complement the High-Performance Linpack (HPL) benchmark currently used to rank supercomputers in the TOP500 list. This new benchmark solves a large sparse linear system using a multigrid preconditioned conjugate gradient (PCG) algorithm.
