Exploring Job Migration Technique for P2P Grid Systems

P2P Grids can potentially solve large-scale scientific problems by using geographically distributed heterogeneous resources. However, a number of major technical obstacles must be overcome before this potential can be realized. One problem critical to the effective utilization of P2P Grids is the efficient scheduling of jobs. This study addresses the above-mentioned problem by describing and evaluating a P2P communication model, a P2P resource monitoring system and a job migration mechanism. In this study, the authors propose a P2P communication mechanism, which is built to deliver various information across heterogeneous Grid systems. Based on this P2P communication mechanism, they can develop job migration technology and then improve the usage of distributed computing resources.

(Amoretti et al., 2005; Shan et al., 2002; Shudo et al., 2005) In this study, we propose a P2P-based mechanism to form a P2P Grid platform and harness the main functionalities of P2P and Grid systems. In general, the job submission in grid systems is carried out by a global resource broker to distribute load. In this article, we propose a campus-to-campus Uni-P2P communication model to integrate the Taiwan Unigrid project (http://www.unigrid.org.tw/) and the Taiwan TIGER project (Yang et al., 2005) by a P2P communication mechanism which builds the communication pipes among sites in different grid systems. This campus-tocampus Uni-P2P communication model also provides a P2P resource monitoring system that captures the dynamic resource usage and a job migration mechanism that improves the idle resource utilization. The concept of super peers, which exhibit more powerful computing ability, bandwidth and hardware capacity, is also considered in this Uni-P2P communication model to improve the efficiency of searching distributed resources. The Uni-P2P communication model is currently under development and a prototype implementing the main components is in the initial testing phase. In this article, we limit our description to the system architectural features and to the preliminary experimental results in the job migration across different sites and different VOs. The rest of the article is structured as follows: Related work is discussed in Section 2 followed by P2P concepts and architectural overview in Section 3. Experimental results are explained in Section 4. Section 5 describes future directions of the project.
