%global desc \
High Performance Geometric Multigrid (HPGMG-FV) is a benchmark\
designed to proxy the finite volume based geometric multigrid linear\
solvers found in adaptive mesh refinement (AMR) based applications\
like the Low Mach Combustion Code (LMC).  HPGMG-FV is being used to\
conduct computer science (e.g. Top500 benchmarking, programming\
models, compilers, performance optimization, and auto-tuners),\
computer architecture, and applied math research.
