Proceedings of the 4th international workshop on Middleware for grid computing

Abstract

The first MGC workshop held on June 2003, in conjunction with the Middleware Conference, in Rio de Janeiro, Brazil, MGC'2003, saw a variety of efforts in Middleware for Grid Computing. There were 16 technical presentations and discussions on several stimulating topics including, Classic Grids, Object Oriented technologies, Service-based Grids, Open grid Service Architecture, Agent Grid, Interactive Grid, Grid Economy / Scheduling, and Portlets. Following the workshop, extended and thoroughly revised versions of the papers were invited to a Special Issue of Concurrency and Computation: Practice and Experience Journal published in 2004.The 2nd workshop in the MGC series brought together researches in the field of middleware for grid computing, addressing topics that emerged from 2003, and some novel ones such as, Strategies and Protocols for obtaining Quality of Services, Virtualization, Wireless Grids, Data Grid Middleware, Semantic Grid Middleware, Dependability and Fault Tolerance in Grid Middleware and Managing Information. This workshop received an unprecedented number of high-quality submissions. Fifteen full papers and nine posters were chosen for the workshop proceedings out of the forty-eight papers originally submitted. The presenters highlighted issues and solutions in one or more of the themes identified for the workshop. Following the second workshop, thoroughly revised selected papers were invited to a Special Issue of Concurrency and Computation: Practice and Experience Journal to appear in 2005/2006.MGC'2003, MGC'2004 and MGC'2005, generated substantial interest in the community and it is expected that this interest will continue. Far from exhausting the topics of interest, they have paved the way for a third edition of the workshop in the series. For MGC 2006 workshop, researchers from the various GRID middleware communities were encouraged to submit and present original work to be considered for publication.The goal of the fourth edition of the MGC workshop is to bring together researches in the field of middleware, addressing largescale and real world problems in grid environments, including Grid and Web Services Architectures and Middleware, Object Metadata and Schemas in Grid Middleware, Programming Models and Tools in Grid Middleware, Resource Management and Scheduling, Strategies and Protocols for QoS in Grid Middleware, Information Services in Grid Middleware, Dependability and Fault Tolerance in Grid Middleware, Performance Evaluation and Modeling in Grid Middleware, Agent-based Approaches in Grid Middleware, Utility computing, Core Grid Infrastructure, Grid Security, Virtualization in Grid Middleware, Wireless Grids Middleware, Data Grid Middleware, Peer to Peer Protocols in Grid Computing, Network Support for Grid Computing, Grid Application Frameworks, Portals and Portlet Containers, Adaptive/Autonomic Middleware, and Messaging in Grid Middleware.The fourth workshop received a good number of high-quality submissions and fourteen papers were selected for these proceedings out of the forty-two originally submitted. Additionally 7 posters have been accepted. The presenters highlight issues and solutions in one or more of the themes identified for the workshop.
