摘　　要：传统的多GPU处理器集群任务调度分配方法采用时间间隙分配的方法,不考虑各个任务的执行要求和每个计算机节点的实际运算能力,整体的执行效率低。提出一种基于嵌入式Quartz混合调度的多GPU处理器平台任务分配设计方法,采用多处理器模拟计算机系统中的多个运算节点,对不同的任务,根据任务的运算量需求和分配到计算机的实际运算能力,实现动态的任务分配,采用混合任务调度,系统具有很好的鲁棒性,采用一组实际任务进行测试实验,结果显示,采用基于嵌入式Quartz混合调度的方法,任务的执行时间大大减少,具有很好的效率改善结果。Traditional multiprocessor task scheduling cluster distribution method the time interval method, without consider-ing each task execution requirements of each computer nodes and actual operation ability, the overall execution efficiency is low. Put forward a kind of multiprocessor platform based on embedded Quartz hybrid task scheduling task assignment de-sign method of the multiprocessor simulation to multiple computing nodes in a computer system, for different tasks, accord-ing to the computation of the task requirements and assigned to the computer practical operation ability, realizes the dynam-ic task allocation, the hybrid task scheduling, the system has good robustness, using a set of practical tasks to test experi-ment, the results show that the method based on embedded Quartz hybrid task scheduling and task execution time is greatly reduced, has the very good efficiency to improve results.
