Grid Computing Using geographically distributed and interconnected computers together for computing and for resource sharing.

“The grid virtualizes heterogeneous geographically disperse resources” from "Introduction to Grid Computing with Globus," IBM Redbooks

4

Introduction to Grid computing and the Grid computing course

Same as behind early development of networks that became the Internet -- Connecting computers at distributed sites for high performance computing.

However, Grid computing is about collaborating and resource sharing as much as it is about high performance computing.

Original driving force behind Grid computing

5

Virtual Organizations

Grid computing offerspotential of virtual organization

-- groups of people, both geographically and organizationally distributed, working together on a problem, sharing computers AND other resources such as databases and experimental equipment.

6

Crosses multiple administrative domains

Another hallmark of larger Grid computing projects.Resources being shared owned either by members of virtual organization or donated by others.

Introduces challenging technical and social-political challenges.

Requires true collaboration.

7

Interconnections

Usually grid computing employs the Internet to interconnect the computers.

Standard Internet protocols are used.

Focus now on using standard Internet protocols and technology, i.e. HTTP, SOAP, web services, etc.,

Our Grid Computing Course

Taught on North Carolina Research and Education Network (NCREN) that connects all 16 state campuses and also private institutions

Fall 2004: 8 sites Fall 2005: 12 sites Spring 2007: 3 sites Fall 2008: 5 sites Spring 2010: 8 sites

Spring 2010 has 70+ students

Grid Computing Course

Undergraduate/first yr graduate (prereqs C/Java) Hands-on with distributed grid infrastructure Teleconferencing facilities - students and faculty at

many institutions participating Expert guest speakers near end of course Probably first such course for undergraduate students

using large-scale teleconferencing facilities and a truly distributed grid infrastructure.

Approach

Very hands-on (7 programming assignments) A top-down perspective (from 2007) Although best described as alternating between high-

level and low-level view of Grid Computing Start course with using tools (i.e. a portal) that a typical

Grid User would use. To avoid issues with many students using centralized

servers, several activities done of student’s own computer
