摘要
提出一种虚拟计算系统体系结构的自适应重构框架,以解决任务特征与体系结构的动态匹配问题。实现面向动态需求变化和面向物理资源变化的重构算法,在任务特征模型或底层物理结构变化时,能自适应进行线程及虚拟机的聚集,以形成新的任务分配和调度结构,使虚拟计算系统具有较高的运行效率,并通过虚拟机迁移,确保系统负载均衡。
This paper presents a self-adaptive framework of Architecture of Virtual Computing System(AVCS) which provides an idea to solve the problem of applications not matching the architecture of AVCS.Two self-adaptive reconfiguration algorithms oriented the change of dynamic requirements from applications and physical resources are designed in this framework,which enable the threads gathering and virtual machines gathering automated and form a new task assignment and scheduling structure to improve the performance of virtual computing systems.Meanwhile,the virtual machines migration in the algorithms is implemented to keep the load balancing.
