Clarens - Narada Integration in GAE

Abstract

Grid technology and peer-to-peer (P2P) computing share the common focus on binding the heterogeneous resources across the multiple administrative domains. There exists synergy between P2P and Grid in terms of interaction of nodes. Grid focuses on scaling the resources on the edges of the network and P2P systems provide protocols for sharing and exchanging data among the end nodes. Moreover Grid technology tends to saturate the resources as grid is scaling from hundred to thousands of nodes. Grid brings an enormous amount of nodes which are connected to each other without any network management and generates large amount of network traffic and thus results in the wastage of network resources. P2P style decentralized architecture is needed to avoid the potential bottlenecks. P2P paradigm with lot of benefits over client/server architecture, especially for grid computing, provides high speeds, high independence, low cost and most importantly, decentralized architecture. This project intends to provide a P2P based infrastructure for Grid frameworks in order to provide decentralized and network efficient communication between the nodes with low network costs. Grid-Enabled Analysis Environment (GAE) is used as a Grid framework and NaradaBrokering is used a P2P framework to serve the purpose. GAE is such a Grid based system build around Services Oriented Architecture (SOA) and JClarens is a Java based Clarens web services framework on which GAE services are hosted. NaradaBrokering is an open source, distributed and asynchronous publish/subscribe messaging framework that provides messaging services between the end peers in a highly resource effective manner.
