1. Seminar Grid Computing ‘05 Hui Li Sep 19, 2005

2. Overview Brief Introduction Presentations Projects Remarks

3. 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

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

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

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

7. 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
