PAMM:一种面向基于内存共享的域间通信的优化模型

云计算平台和虚拟化技术的结合为虚拟机域间通信带来了新的需求,基于内存共享的域间通信可以提高运行在同一物理机上的虚拟机间的通信效率。但是,基于内存共享的域间过程中产生的上下文状态切换限制了其优化能力。引入一种新的内存共享模型PAMM,即通过添加一个管理模块对内存共享过程中所传递的内存页进行聚合管理,减少申请超级调用的次数,以达到减少状态切换的目的。实验表明,PAMM能够提升基于内存共享的域间通信的通信效率。

PAMM:An Optimized Module for Inter-domain Communication Based on Shared Memory

The combination of cloud computing platform and virtualization technologies has brought new communication requirements to us.The inter-domain communication based on shared memory can improve the efficiency of the communication between the virtual machines running on the same physical machine.But the status-sitching in the process of memory sharing limits the optimization ability of the proposed method.New memory sharing model PAMM,by adding a management model which can aggregate memory pages in the process of memory sharing and reduce the number of super calling application,achieves the purpose of reducing the number of status-switching.The experiment shows that PAMM can enhance the efficiency of inter-domain communication based on shared memory domains.
