Grid Computing Activities within the Department of Computer Science at UNC-Charlotte
ITSC 8110 Introduction to Information Technology Research 7:30 pm, Wednesday, Nov 1, 2006
Barry WilkinsonDepartment of Computer ScienceUNC-Charlotte
Outline
• Brief description of grid computing
• Activities:
• Supercomputing 2003 conference demonstration• Grid Computing Course (2004- )• VisualGrid Project (2005- )• SURAGrid
“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
Usually, involves teams working together on a common goal, sharing computing resources and possibly experimental equipment.
Crosses multiple administrative domains.
Geographically distributed grid computing team called a virtual organization.
Applications
Originally e-Science applications– Computational intensive
• Not necessarily one big problem but a problem that has to be solved repeatedly with different parameters.
– Data intensive.– Experimental collaborative projects
Now also e-Business applications to improve business models and practices.
Supercomputing 2003 Demonstration
First personal contact with grid computing (November 2003).
Participant in Supercomputing 2003 demo organized by the University of Melbourne (Raj Buyya).
21 countries, numerous sites.
Grid Computing Course Taught on North Carolina
Research and Education televideo network that connects all 16 state campuses and also private institutions
Fall 2004: 8 sites Fall 2005: 12 sites Undergraduate/graduate

VisualGrid ConfigurationVisualGrid portal
National AttentionListed as one of the portals to use OGCE2
X509 certificates used to provide security in a grid system.
Each user needs a certificate issued by a “certificate authority” (CA).
Grid systems use a so-called user proxy certificates to allow resources to control resources on the user’s behalf.

Multiple Grid Nodes
With multiple grid nodes, users need:
Account on each system, and access control set accordingly.
A certificate acceptable by the local certificate authority (i.e. signed by a CA it trusts)
Getting an accountGo to portal and select “register”
