Detailed description
miniGMG is a compact benchmark for understanding the performance challenges associated with geometric multigrid solvers found in applications built from AMR MG frameworks like CHOMBO or BoxLib when running on modern multi- and manycore-based supercomputers. It includes both productive reference examples as well as highly-optimized implementations for CPUs and GPUs. It is sufficiently general that it has been used to evaluate a broad range of research topics including PGAS programming models and algorithmic tradeoffs inherit in multigrid. miniGMG was developed under the CACHE Joint Math-CS Institute. Note, miniGMG code has been supersceded by HPGMG.
