International Journal of Information Technology Vol. 11 No. 3 2005 (Special Issue) Guest Editorial Introduction The Second Workshop on Grid Computing & Applications (GCA 2005) was held on 05 May 2005 under the auspices of GridAsia 2005 at Biopolis in Singapore. This workshop series seeks to meet the needs of a large and diverse audience, including researchers, practitioners, educators, and users. The objective of this workshop is to promote research and development of Grid Computing & Applications by: * Providing a forum to introduce and discuss new research results, concepts, and technologies; * Providing practitioners an exposure to and an evaluation of evolving research, tools, and practices; * Providing researchers an exposure to issues and challenges of Grid Computing adoption and applications; and * Encouraging the exchange of Grid Computing technologies and experience. The technical program of the workshop features invited speakers and paper presentations by authors from Singapore as well as overseas delegates from Australia, China, India, Japan, Malaysia, Puerto Rico, Thailand, and UK. This workshop serves as an important forum for researchers to interact and learn from each other. It creates the opportunities for the like-minded to share knowledge and results, as well as establish contacts for collaboration. With the National Grid in Singapore entering its second phase with an emphasis on promoting Grid Computing adoption by industry users, this workshop allows interested parties to benefit from the experience of practitioners who have undertaken grid-enabling of applications and grid implementation. Overview of Special Issue The 17 papers in this special issue are drawn from the GCA 2005. They are divided into three parts. Part 1 provides the larger context of GCA 2005. The two papers document some of the lessons learnt and experience gleaned from the initial phase of the National Grid Pilot Project in Singapore. The second part of this special issue group together the domain-specific and applications related papers. These six papers focus on how Grid Computing has been applied in bioinformatics, manufacturing, education and others. The nine papers in Part 3, which will appear in a separate volume of the journal, evolve around core Grid technologies, including security, middleware, Grid services, problem solving environments, resource management & allocation, workflow and tools. We thank the Program Co-chairs, Program Committee members and reviewers for refereeing the great number of papers that we received in response to the GCA 2005 call. Their generous contributions are gratefully acknowledged. Finally, we would like to thank the author for their excellent contributions.
