Multi site virtual cluster computing
In this paper, we propose a sophisticated cluster virtualization mechanism consisting of 2 key systems. An L2 network extension of virtual machine networks permits clear deployment over networks for distributed virtual cluster nodes, and a clear package caching mechanism significantly optimizes info transfers in virtual cluster deployment over network latencies. Experimental results show multisite virtual clusters have enough feasibility in Dismal environments and guarantee great scalability for a sizeable number of virtual nodes.
Lately , Grid computing has gathered the notice as a method to efficiently and effectively exploit computational resources among multiple organisations. the prevailing Grid technologies don't always supply the computational environment enough to satisfy users' needs due to the heterogeneity and disconnect among computational resources on the Grid.
For the reason, we've been making an attempt to develop a new Grid middleware technology that allows for a virtual cluster composed from virtual computational resources by Xen as a virtualization technology on top of an overlay network realized by PIAX as an overlay networking technology. In this paper, we propose a communication relay mechanism that permits Xen-based virtual computational resources composing a virtual cluster to speak with one another toward the future development of such a Grid middleware technology. The analysis shown in the paper signals that such a virtual cluster is possible and could work effectively for computationally-intensive applications.
