Overview

The stencil domain specific language (SDSL) is a domain-specific language for expressing stencil computations. SDSL is loosely based on the RNPL and SNPL languages used for rapid prototyping of partial differential equation solvers, although the resemblance is mostly cosmetic and no code is shared between the projects. The purpose of SDSL is to provide a programming language that allows for the specification of non-trivial stencil computations in a form that enables the generation of high-performance implementations that can be obtained in a performance-portable manner on multiple platforms.

SDSL can be embedded in C, C++, and MATLAB code. Currently, backends exist for generating (1) affine C99 code intended for further optimization by polyhedral compiler tools including PolyOpt/C and PoCC, (2) CUDA code with overlapped tiling optimizations as described by Holewinski, Pouchet, and Sadayappan, and (3) short-vector SIMD code for SSE2, SSE4, AVX, Xeon Phi (experimental), and ARM NEON (experimental) vector ISA with split tiling and DLT optimizations.
