1. 1 Barry Wilkinson University of North Carolina, Charlotte Clayton Ferner University of North Carolina, Wilmington NSF CCLI Showcase SIGCSE 2007 Friday, March 9, 2007 STATE-WIDE UNDERGRADUATE GRID COMPUTING COURSE

2. 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. 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. 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. 5 Grid Computing Course  Taught on North Carolina Research and Education televideo network that connects all 16 state campuses and also private institutions

6. 6 Grid Computing Course Participants 14 North Carolina institutions (Total 2004 - 2007):  Appalachian State University  Elon University  North Carolina Central University  North Carolina State University  University of North Carolina at Asheville  University of North Carolina Chapel Hill  University of North Carolina at Charlotte  University of North Carolina at Greensboro  University of North Carolina at Pembroke  University of North Carolina at Wilmington  Western Carolina University  Winston-Salem State University  Lenoir Rhyne College,  Wake Technical Community College.

18. 18 Guest Speakers (2004)  Professor Daniel A. Reed, Chancellor's Eminent Professor, Vice Chancellor for IT and CIO, UNC-Chapel Hill, Director of Institute for Renaissance Computing, UNC Chapel Hill, Duke University, and NC State University: – “Grid computing: 21st Century Challenges.”  Dr. Wolfgang Gentzsch, Managing Director, MCNC Grid Computing and Networking Services: – “Grid Computing in the Industry”  Chuck Kesler, Director, Grid Deployment and Data Center Services, MCNC: – “Security Policy, Legal, and Regulatory Challenges in Grid Computing Environments”  Professor Ian Foster, Argonne National Laboratory and University of Chicago: – “The Grid: Beyond the Hype.” Taped presentation (originally given at Duke University, Sept. 14th, 2004).

19. 19 Guest Speakers (2005)  Jeff Schmitt, genesismolecular.com  Jim Jokl, University of Virginia, Art Vandenberg, Georgia State University, Mary Fran Yafchak, SURA: – "Development and Implementation of an Inter-Institutional Multi- purpose Grid”  Lavanya Ramakrishnan, The Renaissance Computing Institute (RENCI), UNC Chapel Hill, NC State University, and Duke University: – "Leveraging the Grid: Application Perspective”

20. 20 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.

21. 21 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.
