1 Grid Computing Activities within the Department of Computer Science at UNC-Charlotte ITSC 8110 Introduction to Information Technology Research 7:30 pm, Thursday, August 30, 2007 Barry Wilkinson Department of Computer Science UNC-Charlotte

2 Outline Brief description of Grid computing Some Activities: Supercomputing 2003 conference demonstration Original Grid Computing Course ( ) New Grid Computing Course (2007-) VisualGrid Project ( ) SURAGrid PhD project (2007-)

3 “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

4 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.

5 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.

6 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.



9 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  Spring 2007: 3 sites (experimental)  Undergraduate/graduate  ITCS 4146/5146

15 Assignment 1Using Grid computing portal Assignment 2Using the Grid through a command line. Assignment 3Using a scheduler (Condor-G) Assignment 4Installing GT4 core. Creating, deploying, and testing a GT4 Grid service. Assignment 5Installing and using GridNexus workflow editor to create and execute workflows. Assignment 6Implementing a portlet with OGCSE2/Gridsphere portal. Assignment 7MPI assignment on Grid Mini-projectDeveloping grid computing assignment Programming Assignments (Spring 2007) Assignments 4, 5, and 6 require students to install significant software packages on their own computer.

21 National Publicity Science Grid This Week Feature story

22 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.

23 VisualGrid Project (Completed)  Goal: Collaborative environmental visualization research using a grid computing infrastructure  Jan 2006 – Dec 2006  Involves two sites: – UNC-Charlotte – UNC-Asheville  plus Environment Protection Agency, Raleigh, NC (funding agency) EPA
