Split Compilation: an Application to Just-in-Time Vectorization Abstract

In a world of ubiquitous, heterogeneous parallelism, achieving portable performance is a challenge. It requires finely tuned coordination, from the programming language to the hardware, through the compiler and multiple layers of the run-time system. This document presents our work in split compilation and parallelization. Split compilation relies on automatically generated semantical annotations to enrich the intermediate format, decoupling costly offline analyses from lighter, online or just-in-time program transformations. Our work focuses on automatic vectorization, a key optimization playing an increasing role in modern, power-efficient architectures. Our research platform uses GCC’s support for the Common Language Infrastructure (CLI ECMA-335); this choice is motivated by the unique combination of optimizations and portability of GCC, through a semantically rich and performance-friendly intermediate format. Implementation is still in progress
