WebIntroduction. This article describes a GPU OpenCL implementation of single-precision matrix-multiplication (SGEMM) in a step-by-step approach. We'll start with the most basic version, but we'll quickly move on towards more advanced code. Each step introduces a new optimisation - and best of all - working OpenCL code.
