Grid Computing Activities within the Department of Computer Science at UNC-Charlotte
Outline
• Brief description of grid computing
• Activities:
• Supercomputing 2003 conference demonstration• Grid Computing Course (2004- )• Bioinfomatics algorithm hardware accelerator
(participant)• VisualGrid Project (2005- )
“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
Need to harness computers
Original driving force behind grid computing the same as behind the early development of networks that became the Internet:
– Connecting computers at distributed sites for high performance computing.
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.
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.
Subsequent activities
• Projects:
• Grid Computing Course (2004- )• VisualGrid Project (2005- )• Bioinfomatics hardware accelerator
(participant)• SURAGrid participant
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 Principally an
undergraduate course, (some graduate students)

Challenges - Technical Issues(grid computing)
Setting up the grid infrastructure – very “challenging”
Providing students with a stable distributed grid computing platform
Moving the students through a set of detailed programming assignments in the face of system and student problems.
Relied heavily on faculty contacts at each site.

Achievements
• Created a secure multi-institutional research grid between UNC-Charlotte and UNC-Asheville with distributed compute and data storage resources.
• Developed VisualGrid portal, a customized web-based interface to access combined VisualGrid resources and execute applications. Single sign-on to all resources. HTTPS server.
• Provided simplified one-step on-line registration for new users.
• Provided a Certificate Authority for authenticating users.
• Developed “portlets” within portal including for the CMAQ application to greatly simplify its use.

National AttentionListed as one of the portals to use OGCE2
X509 certificates are 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)
