Stencil computations are a class of algorithms which perform nearest-neighbor
computation, often on a multi-dimensional grid. This type of calculation forms the
basis for computer simulations across almost every field of science, including numerical
relativity and astrophysics. The increasing computational speed of graphics processing
units (GPUs) make their use for stencil computations an interesting goal.
However, achieving highly efficient implementations is often nontrivial, as numerous
publications attest. In this talk, I present our proposal of an analytic performance
model for stencil codes on GPUs, which both delivers close-to optimal performance,
but at the same time does not require extensive tuning at compile or run time.
