Reference Implementation

A detailed description of the reference MPI+OpenMP implementation is forthcoming.

• introduction to finite volume representations and geometric multigrid
• boxes
• levels
• blocks
• ghost zone (halo) exchanges
• stencils and intra-level operators
• restriction, prolongation (interpolation), and inter-level operators
• U-Cycles, V-Cycles, and F-Cycles (FMG)
• timers and understanding the output
• alternate smoothers
• alternate operators and discretizations
• alternate boundary conditions
• alternate coarse-grid solvers
