A P2P-based virtual cluster computing using PIAX

Providing large scale, stable and robust computing environments is indispensable to various fields including scientific researches as well as business. Grid computing has gathered considerable attention as a means to efficiently and effectively utilize computational resources among multiple organizations. However, the current Grid technologies do not always provide the computational environment enough to satisfy users´ requirements because of the heterogeneity and disconnect among computational resources on the Grid. For the reason, we have been attempting to develop a new middleware that leverages newly emerging Cloud technologies and allows for a virtual cluster composed of 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 system that allows Xen-based virtual computational resources composing a virtual cluster to communicate with each other toward the future development of Grid and Cloud middleware technology. The evaluation shown in the paper indicates that such a virtual cluster is feasible and could work effectively for computationally intensive applications.
