1. outline.1 Grid Computing Fall 2008 Tuesday/Thursday 11:00 am - 12:15 pm Instructors Grid Computing, B. Wilkinson, 2008 Aug 205 2008 Dr. Clayton Ferner University of North Carolina Wilmington Dr. Barry Wilkinson University of North Carolina Charlotte

2. outline.2 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

3. outline.3 Virtual Organization Usually, 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.

4. outline.4 Interconnections Usually grid computing employs the Internet to interconnect the computers. Standard Internet protocols are used.

5. 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.5

6. outline.6 Course credit This 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.

7. outline.7 Course virtual organization Five sites scheduled to receive course:

8. outline.8 Course grid structure UNC-W UNC-A UNC-C coit-grid01.uncc.edu * coit-grid02.uncc.edu * coit-grid03.uncc.edu * coit-grid04.uncc.edu * coit-grid05.uncc.edu ** Course portal trc.cs.unca.edu torvalds.cis.uncw.edu * 3.4 Ghz dual Xeon processors ** 2.93 Ghz 4 quad-core Xeon processors

9. outline.9 Class schedule Each university has its own class schedule, see: http://www.cs.uncc.edu/~abw/ITCS4146F08/ academiccalender.html Classes will start on Tuesday Aug 26, 2008 and will end on Tuesday Dec. 2, 2008. to accommodate different schedules.

10. 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.

11. 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.

12. outline.12 Course Home Page http://www.cs.uncc.edu/~abw/ITCS4146F08 for announcements, slides, assignments, reading materials, tests dates, etc. Visit regularly. Password protected because some materials restricted to students in class. Password provided separately.

14. outline.14 Course Text Draft chapters of a course textbook found here: http://www.cs.uncc.edu/~abw/ ITCS4146F08/GridComputingBook/index.html (under Reading/on-line materials) This material is for the class participants only.

15. outline.15

16. outline.16 Outline of Topics Introduction to Grid computing Job management, schedulers Workflow Grid computing system infrastructure design Security Portal design Grid-enabling applications More details of course home page

17. outline.17 Assignments and Grading Several 1-2 week prewritten programming assignments (tasks)‏ –Job submission thro portal –Job submission on command line –Job scheduling –Workflow editor –Grid services –Portlet design Mini-project (grid application)‏ Class tests (2)‏ Final test Small print: Subject to change. The instructor reserves the right to change the assignments and the grading to make it easier or harder. 50% 10% 25% 15%

18. outline.18 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, asked to extend the work - e.g. add functionality to a service.

19. outline.19 Systems and Software Two types of systems used: Dept. 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

20. outline.20 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!

21. outline.21 Class tests and assignment submission Blackboard at UNC-C used for multiple-choice class tests and for submitting assignments. https://ncvista.blackboard.com/webct/ logon/645986001091 Everyone will be given an account on this system.

24. outline.24 Expectations Read all materials provided. Print out slides before class, read them, and annotate them during class. Ask questions during class and participate in class discussion.

25. outline.25 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.

26. outline.26 NCREN facility continued 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.
