Stencil computation is a classic computational kernel present in many high-performance scientific applications, like image processing and partial differential equation solvers (PDE). A stencil computation sweeps over a multi-dimensional grid and repeatedly updates values associated with points using the values from neighboring points. Stencil computations often employ large datasets that exceed cache capacity, leading to excessive accesses to the memory subsystem. As such, 3D stencil computations on large grid sizes are memory-bound.
