Abstract

Abstract SIMD computer systems offer tremendous potential speed‐ups but aggressive compilation strategies are required to realize this potential. The paper presents the Compass SIMD compiler technology developed while working on a number of SIMD compilers. Although the various targets have much in common, our increased understanding of the SIMD compilation process on each successive project and the differences in the targets themselves has affected the shape of each compiler.
