摘要

并行已经成为最大化处理器性能和功率效率的主要方式。但是,由于手工创建并行程序困难且容易出错,因此迫切需要将传统程序转换为利用现代多核系统的自动方法。HELIX编译器转换就是这样一种技术,它已被证明可以有效地为真正的六核处理器自动并行化单个顺序程序。我们在更广泛的HELIX研究项目的背景下描述了这种转变,该项目旨在通过对其架构、编译器和操作系统进行协调更改来优化多核处理器的吞吐量。目标是通过自适应算法提取和调优线程级并行性,使自动并行化在多道编程设置中成为主流。

The HELIX project: Overview and directions
Parallelism has become the primary way to maximize processor performance and power efficiency. But because creating parallel programs by hand is difficult and prone to error, there is an urgent need for automatic ways of transforming conventional programs to exploit modern multicore systems. The HELIX compiler transformation is one such technique that has proven effective at parallelizing individual sequential programs automatically for a real six-core processor. We describe that transformation in the context of the broader HELIX research project, which aims to optimize the throughput of a multicore processor by coordinated changes in its architecture, its compiler, and its operating system. The goal is to make automatic parallelization mainstream in multiprogramming settings through adaptive algorithms for extracting and tuning thread-level parallelism.
