Grid ComputingUsing 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
outline.3
Virtual OrganizationUsually, grid computing involves teams working together on a common goal, sharing computing resources and possibly experimental equipment.
The geographically distributed grid computing team and their resources is called a virtual organization.
The resources shared include software and experimental data.
outline.4
Interconnections
Usually grid computing employs the Internet to interconnect the computers.
Standard Internet protocols are used.
Grid Course
• Rather unique - combine distance learning techniques with distributed computer systems creating both a virtual organization of students and a distributed Grid computing platform.
• Provides hands-on experiences of Grid computing software and the underlying techniques

outline.6
Course creditThis course can be taken by students at any university connected to the NCREN, for credit at their institution.
Course number assigned by the institution.
Listed as an undergraduate course but can be taken for graduate credit with approval of your institution.
More expected from graduate students.

Class scheduleEach university has its own class schedule, see:
http://www.cs.uncc.edu/~abw/ITCS4146S10/academiccalender.html
Classes will start on Tuesday Jan 12, 2010 and will end on Thursday April 22, 2010.
to accommodate different schedules.
outline.10
It may be necessary for students at sites with breaks that do not coincide with UNC-C's breaks to watch recordings of classes later.
outline.11
Prerequisites• Programming skills as acquired by typical junior/ senior undergraduate Computer Science student.
• Programs either (simple) C programs or (simple) Java programs depending upon context.
It is expected that you have a computer (PC or mac)!
Some work best done on your own computer.
Grid computing platform is a Linux system.
You will need to be able to perform (simple) Linux system commands. We provide documentation.

Assignments and Grading• Seven assignments covering:
– Job submission thro portal– Job submission on command line– Job scheduling– Workflow editor– Grid services– Portlet design
Detailed assignment write-ups in each case, see course home page.
• Class tests/on-line quizzes (2)• Final test/on-line quiz• Small print: Subject to change. The instructor reserves the right to change the assignments and the grading to make it easier or harder.

Prewritten Programming Assignments
• Detailed instructions provided on achieving a task (creating a grid service, running a GT 4 job, etc.)
• Simply follow instructions.
• At end, typically asked to extend the work – e.g. add functionality to a service.
• Write a report of what you did and submit through Moodle, see later for details.
outline.18
Systems and SoftwareTwo types of systems used:
• Grid computing servers
- Will be used for some assignments, most notably to schedule and run jobs.
- Access:• Through a web-based portal, or • Though an ssh connection.
depending upon assignment
outline.19
• Lab or personal PCs
• Will be used for some assignments. • Require specific open-source software packages
installed. • Packages can easily be downloaded and
installed on your own PC, so that you can do the work at home.
• Ideally students should install these software packages on their own system as directed in assignments to do assignments. You will learn so much!

Expectations
• Read all materials provided.
• Read slides before class. Take additional notes during class
• Ask questions during class and participate in class discussion.
outline.23
NCREN facility(North Carolina Research and
Education Network)
Site interaction
Each site will be using their NCREN facility, which provides microphones for individuals to speak.
Please feel fee to speak at suitable times but remember that NCREN needs to be able to recognize the site and speaker, so first announce your institution and name.
outline.24
NCREN facilitycontinued
• Since most microphones are turned on all the time, any sound will be heard across all sites unless a site turns their microphones off, so try to avoid unnecessary sounds.
• Fans from a laptop can be especially disturbing, so move laptop away from a microphone.
• Turn cell phones off.
