"""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. """
