A Network Substrate for Peer-to-Peer Grid Computing beyond Embarrassingly Parallel Applications

Embarrassingly parallel grid applications require no inter-worker interaction. Thus, the underlying communication infrastructure is based on the simple but well understood client/server execution model. This is no longer sufficient if more demanding parallel applications that require true peer-to-peer interaction are to be deployed on grids. In this paper, we propose the industrial-strength eXtensible Messaging and Presence Protocol (XMPP) as a network substrate for these non-trivial peer-to-peer grid computing applications.
