Grid Computing, B. Wilkinson, 2004 outline.1

Grid Computing, B. Wilkinson, 2004
outline.2

• Using usually geographically distributed and interconnected computers together for high performance computing and/or for resource sharing.
Notice “usually”, “and/or” - many definitions of grid computing and applications.
Grid Computing, B. Wilkinson, 2004 outline.3

The interconnection now “usually” made through the Internet to multiple administrative domains.
Resource sharing - can involve a geographically distributed team ( virtual organization ) and resources in addition to computers (software, experimental equipment etc.)

This course can be taken by students at any university connected to the NCREN for credit at their institution.
Listed as an undergraduate course but could be taken for graduate credit with my approval (and your institution).
Graduate students can expect more demanding work.
Grid Computing, B. Wilkinson, 2004 outline.6

Each university has its own class schedule.
Classes will start on August 26th, 2004 (WCU's start date).
Last class presentation will be on Thursday December 2nd,
2004.
No class on Thursday October 14th, 2004 (WCU Fall break).
It will be necessary for students at sites with breaks that do not coincide with WCU's breaks to watch recordings of classes later.
Final exams will be scheduled according to the local schedule.

• Detailed instructions provided on achieving a task
(creating a web service, grid service, etc.,)
• Simply follow instructions.
• At end, asked to extend the work - e.g. add functionality to a service.
These assignments require specific distributed computing software available either locally, or through remote access to WCU.
