嵌入式多处理器系统混合调度机制的研究

摘要

Generic multi-processor systems in high performance computing applications such as Intel, NVIDIA Tesla systems have been developing rapidly, but their cost and power consumption were soaring;low-end hardware, especially in embedded systems that make up the cluster as an alternative to traditional platforms got attention and rapid development.We discuss a low cost infrastructure and implementation of embedded multiprocessor systems, take advantage of platform features to implement a special MIMD structure,which is capable of supporting a hybrid scheduling system adaptable to different working environments, tasks, and conditions.Test results and their analysis show preliminarily that the system can support a variety of hybrid scheduling policy for scheduling and can signifi-cantly improve the processing power of the system.%通用高性能计算机需求不断增加，传统多处理系统得到了快速发展，但其成本和功耗也大幅攀升，以嵌入式系统构成群集替代传统平台成为未来焦点。讨论了一种成本低廉的嵌入式多处理器系统的基本结构与实现，利用平台特性实现了一种特殊MIMD结构，在集中式工作池的基础上能够支持混合调度机制以适应不同工作环境、任务条件需要。试验结果分析表明，该系统能够支持多种调度机制的混合调度策略，更能够较大幅度提升系统的运算能力。
