The Platform-Aware Compilation Environment (PACE)

Abstract : The PACE Project investigated the feasibility of using a combination of characterization-driven optimization, feedback-directed optimization, and automatic selection of transformations to retarget an optimizing compiler to new computer systems. This report provides an overview of the design, the implementation, and the ways in which the PACE components advanced the state of the art in compilation, in performance measurement and attribution, in portable measurement of system characteristics, and in machine learning.
