The document discusses grid computing and the development of computational grids. Key points: - Grids allow for sharing of computing power and resources across geographic locations through networked supercomputers, databases, and instruments. - Major organizations like NASA, DOE, and NSF are working to build computational grids for applications like scientific simulations and instrument control. - Indiana University is involved in grid research through various departments and projects focused on resource sharing, portals, middleware, and more.

1. Grid Computing UITS IT Seminar Series June 2001

2. Beyond the Net, lies the Grid. The Net allows users everywhere to share information. The Grid will allow users to share raw computing power. It’s under construction.

3. What is a Grid? persistent networked environments integrating geographically distributed supercomputers , large databases , and high end instruments coordinated resource sharing and problem solving in dynamic virtual organizations

4. Grid computing is related to but not identical with Parallel computing Distributed computing Pervasive computing

5. Who is building them? Demonstration – SC98 TransPac link from Internet2 to APAN NASA, DOE, DOD, NSF

6. It’s for real. Used to construct: collaborative engineering systems real-time instrument control systems problem solving environments to perform record-setting scientific simulations.

7. You don’t have to be a computer scientist…

8. The bandwagon

9. Student Technology Centers Nearly 1000 new computers Fast ethernet connections SETI@Home screensaver accumulated CPU-hours at the rate of 552 processors on a 24x7 basis Challenges: resource management, security, migration Testbed project – Condor

10. The goal is to create … A scalable, seamless extension of your access point through pervasive networks to a set of resources tied together by a set of ubiquitous common distributed services .

11. A scalable, seamless extension of your access point through pervasive networks ...

12. A scalable, seamless extension of your access point through pervasive networks to a set of resources … Parallel computing is harder There’s more to think about. The technology is less mature. It need not even help Moving bits is slower than crunching them. Formula for success: communication/computation << 1

13. A scalable, seamless extension of your access point through pervasive networks to a set of resources tied together by common services.

14. To Do: Building the middleware, protocols, interoperable communications libraries Building resource management Building social infrastructure Economic exchange mechanisms

15. Building on the Internet, the WWW Uniform naming A seamless, scalable information service A powerful new meta-data language: XML SOAP - simple object access protocol - Uses XML for message encoding, HTTP for protocol. XML-RPC may become standard mechanism for Grid Services.

16. Why bother? Because you have to. Big calculations – more processors, more memory

17. Other reasons: Share resources Share ideas
