STATE-WIDE UNDERGRADUATE GRID COMPUTING COURSE
2“The grid virtualizes heterogeneous geographically disperse resources” from "Introduction
to Grid Computing with Globus," IBM Redbooks
Using geographically distributed and interconnected computers together for computing and for resource sharing.
Grid Computing
3
Virtual Organization
Usually, grid computing involves teams working together on a common goal, sharing computing resources and possibly experimental equipment.
Geographically distributed grid computing team called a virtual organization.The resources shared include software and experimental data.Crosses multiple administrative domains.
4
Applications
Originally e-Science applications– Computational intensive– Data intensive.– Experimental collaborative projects
Now also e-Business applications to improve business models and practices.
5
Grid Computing Course
Taught on North Carolina Research and Education televideo network that connects all 16 state campuses and also private institutions

Challenges - Technical Issues(Grid computing)
Providing students with a stable distributed grid computing platform
Moving students quickly through detailed programming assignments in the face of system and student problems.
Relies heavily on faculty contacts at each site.

Successes
This course was first offered in Fall 2004 and is probably the first such course in the country, and possibly in the world, to involve undergraduate students and so many distributed sites using a televideo system such as NCREN and a truly distributed grid infrastructure.
