Stencil computation is an important class of algorithms used in a large variety of scientific-simulation applications, especially those arising from finite-difference solutions of differential equations representing the behavior of physical phenomenon such as heat dispersion or seismic activity.This talk provides a brief review of stencil computation and Intel® Xeon® and Xeon Phi™ processors, and it describes the YASK (Yet Another Stencil Kernel) framework that simplifies the tasks of defining stencil functions, generating high-performance code targeted for various Intel platforms, and running tuning experiments.A couple of example YASK features are explained, performance results are given, and future work is described.
