摘要
尽管多核处理器现在随处可见，但很少有应用程序能够真正利用它们的多处理能力。数据流编程试图通过在应用程序中表达显式的并行性来解决这个问题。在本文中，我们描述了在单核处理器上执行数据流程序的两种调度策略。我们还描述了使用分布式调度器和无锁通信在多核架构上对这些策略的扩展。我们在MPEG-4 Simple Profile和MPEG-4 Advanced Video Coding解码器上展示了这些调度策略的有效性。
Efficient multicore scheduling of dataflow process networks
Although multi-core processors are now available everywhere, few applications are able to truly exploit their multiprocessing capabilities. Dataflow programming attempts to solve this problem by expressing explicit parallelism within an application. In this paper, we describe two scheduling strategies for executing a dataflow program on a single-core processor. We also describe an extension of these strategies on multi-core architectures using distributed schedulers and lock-free communications. We show the efficiency of these scheduling strategies on MPEG-4 Simple Profile and MPEG-4 Advanced Video Coding decoders.
