Seminar Grid Computing ‘05 Hui Li Sep 19, 2005

Overview Brief Introduction Presentations Projects Remarks

Grid Definition a Grid is "a set of information resources (computers, databases, networks, instruments, etc.) that are integrated to provide users with tools and applications that treat those resources as components within a 'virtual' system". Grid software solutions provide the underlying mechanisms necessary to create such systems, including authentication and authorization, resource discovery, resource management, communications, and information services, etc. Keywords: Virtualization, Middleware

Historically Speaking … Networking ARPANET Communications and Data Sharing: , ftp, telnet, TCP/IP Information Sharing: WWW, HTTP, HTML Resource Sharing: P2P, Web Services, Grids

Why *? Why Grids? –Think beyond only information –Next step in networked computing Why now? –CPU, storage, networking –Academic, Commercial, Governmental, Personal –$funding$

Futuristically Speaking Post Internet Grid Computing, Ubiquitous Computing, Personal Computing $10 bn (IDG)?

Grid Checklist Coordinates resources that are not subject to centralized control Using standard, open, general-purpose protocols and interfaces To deliver nontrivial qualities of service (Performance) Security is a *serious* concern

The Evolution of the Grid Seminar first seminar, p&p structure, parallel applications continuation p&p structure, system centric - LUCGrid p&p structure, development & research Goal: Group learning, interaction & discussion, R & D

Presentations 3 or 4 presentations each class ~30 minutes per presentation minutes talk, 5-10 minutes discussion Participation and discussion are highly promoted, and they will be counted in grading (15%) “Non-trivial” questions
