中文摘要:虚拟机调度算法对并行任务的执行效率考虑不够充分。现代处理器平台具备了多个可用的计算核心，使多个虚拟机并发执行成为了现实。针对多核平台下的并行虚拟机调度优化问题，提出一种基于任务特征虚拟机CON-Credit调度算法。该算法在调度并行任务时，使用动态方式对计算机核心进行分配，采用传统的虚拟机调度算法为执行普通任务的虚拟机进行分配；采用定制的同步算法给执行并行任务的虚拟机分进分配。相关实验显示,CON-Credit调度算法能显著提高并行任务的执行效率。

Dynamic Scheduling Model of XEN Virtual Machine in Multi-core System

Abstract:The virtual machine scheduling algorithm doesn’t fully consider the execution efficiency of parallel application. Modern processors have multiple available computing core, so that concurrent execution of multiple virtual machines become a reality. In this paper, a parallel multicore platform virtual machine scheduling problems, Presents a task-based Virtual Machine CON-Credit scheduling algorithm. The algorithm in the scheduling of parallel tasks, Dynamically allocated using a computer core, using the traditional virtual machine scheduling algorithm to perform common tasks allocated virtual machines; Using custom synchronization algorithm to perform parallel tasks assigned virtual machine. Related experiments show, CON-Credit scheduling algorithm can significantly improve the efficiency of the parallel task execution.
