The goal of the Latin America Grid (LAGrid) workshop is to act as a forum for technical presentations of ongoing research, development and relevant activities in the area of Grid Infrastructures, Services and Applications, in the context of and/or in partnership with Latin America. The event focuses on bringing together researchers and professionals actively working in this field, promoting multi-institutional collaborations between groups of diverse competences.

The LAGrid workshop gives particular attention to the Grid deployment initiatives in Latin America and the challenges they face as regards the distribution of and efficient access to scarce compute, storage and communication resources in this continent. Discussions and studies about new application areas and the potential impact of Grid technology in Latin America are also of main interest. Authors are therefore particularly encouraged to submit reports about their experiences in deploying Grid Infrastructures, Services and Applications.

The areas of interest in LAGrid 2007 include, but are not limited to:

• Cyberinfrastructures in Latin America;
• Impact of Grid technology in Latin America;
• Applications for Latin America;
• Middleware solutions for Latin America;
• Promoting e-Science collaborations in Latin America;
• Funding models supporting Latin America cyberinfrastructures;
• Cost-effective solutions for Latin America;
• Grid economy models for Latin America;
• Role of Grids in broadening participation in science and education in Latin America.

16:30h - Keynote: Towards Truly Ubiquitous Cyberinfrastructure 

James D. Myers

Associate Director, Cyberenvironments and Technologies
National Center for Supercomputing Applications (NCSA) – US

Abstract: As Cyberinfrastructure (CI) continues to advance in terms of capability and aggregate capacity, new scientific use patterns are emerging within and across disciplines, and community scientific plans are being made that assume the availability of ubiquitous CI. NCSA has coined the term cyberenvironments to recognize that addressing the needs of next-generation science, adapting to the changing use patterns for CI, and supporting a broader range of users will require a rethinking of both middleware and user interfaces. This talk will provide an analysis of how scientific use of CI is changing and outline the types of responses in terms of software capabilities and middleware design patterns that will be needed for CI to truly become ubiquitous.
