【摘要】：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。
[Abstract]:With the increasing demand for general-purpose high performance computers, traditional multiprocessing systems have developed rapidly, but their costs and power consumption have also increased dramatically. This paper discusses the basic structure and implementation of a low-cost embedded multi-processor system, and implements a special MIMD structure by using the characteristics of the platform. On the basis of centralized work pool, the hybrid scheduling mechanism can be supported to meet the needs of different working environments and task conditions. The experimental results show that the system can support mixed scheduling policies with multiple scheduling mechanisms. Moreover, it can greatly improve the computing ability of the system.
