From Website: 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 […]

miniAero
From Github: MiniAero is a mini-application for the evaulation of programming models and hardware for next generation platforms. MiniAero is an explicit (using RK4) unstructured finite volume code that solves the compressible Navier-Stokes equations. Both inviscid and viscous terms are included. The viscous terms can be optionally included or excluded. The three problem types that […]
CoMD
From README.md CoMD is a reference implementation of typical classical molecular dynamics algorithms and workloads. It is created and maintained by ExMatEx: Exascale Co-Design Center for Materials in Extreme Environments (exmatex.org). The code is intended to serve as a vehicle for co-design by allowing others to extend and/or reimplement it as needed to test performance […]
CloverLeaf
From http://uk-mac.github.io/CloverLeaf/ CloverLeaf is a mini-app that solves the compressible Euler equations on a Cartesian grid, using an explicit, second-order accurate method. Each cell stores three values: energy, density, and pressure. A velocity vector is stored at each cell corner. This arrangement of data, with some quantities at cell centers, and others at cell corners […]
HPCCG
A simple conjugate gradient benchmark code for a 3D chimney domain on an arbitrary number of processors. Problem Size Discussion From the application README Suggested: Data size is over a range from 25% of total system memory up to 75%. With nx=ny=nz and n = nx * ny * nz Total memory per MPI rank: […]
