  1. Grid ComputingFall 2004Tuesday/Thursday 2:00 pm - 3:15 pmInstructorsDr. Barry WilkinsonWestern Carolina UniversityandDr. Clayton FernerUniversity of North Carolina at Wilmington Grid Computing, B. Wilkinson, 2004

  2. Outline Grid Computing, B. Wilkinson, 2004

  3. Grid Computing • Using usually geographically distributed and interconnected computers together for high performance computing and/or for resource sharing. Notice “usually”, “and/or” - many definitions of grid computing and applications. Grid Computing, B. Wilkinson, 2004

  4. The interconnection - now “usually” made through the Internet to multiple administrative domains. Resource sharing - can involve a geographically distributed team (virtual organization) and resources in addition to computers (software, experimental equipment etc.) Grid Computing, B. Wilkinson, 2004

  5. “The grid virtualizes heterogeneous geographically disperse resources” From "Introduction to Grid Computing with Globus," IBM Redbooks Grid Computing, B. Wilkinson, 2004

  6. Course credit This course can be taken by students at any university connected to the NCREN for credit at their institution. Listed as an undergraduate course but could be taken for graduate credit with my approval (and your institution). Graduate students can expect more demanding work. Grid Computing, B. Wilkinson, 2004

  7. Class schedule Each university has its own class schedule. Classes will start on August 26th, 2004 (WCU's start date). Last class presentation will be on Thursday December 2nd, 2004. No class on Thursday October 14th, 2004 (WCU Fall break). It will be necessary for students at sites with breaks that do not coincide with WCU's breaks to watch recordings of classes later. Final exams will be scheduled according to the local schedule. Grid Computing, B. Wilkinson, 2004

  8. Prerequisites • Preferably programming skills in Java on a Linux system. • Some later work may also involve C/C++ programming. Grid Computing, B. Wilkinson, 2004

  9. Topics • Introduction to grid computing • Web services • Grid services • Security, Public Key Infrastructure • Open Grid Services Architecture (OGSA) • Globus 3.2 • Condor-G • MPI and grid enabled MPI • UNC-W GUI and grid computing applications Grid Computing, B. Wilkinson, 2004

  10. Assignments and Grading 45% 15% 25% 15% • 6 “simple” pre-written programming assignments (tasks) • web services • grid services • Globus job • Condor job • MPI-G2 job • Using UNC-W GUI • Additional programming assignment/project • 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. Grid Computing, B. Wilkinson, 2004

  11. “Simple” Prewritten Programming Assignments • Detailed instructions provided on achieving a task (creating a web service, grid service, etc.,) • Simply follow instructions. • At end, asked to extend the work - e.g. add functionality to a service. These assignments require specific distributed computing software available either locally, or through remote access to WCU. Grid Computing, B. Wilkinson, 2004

  12.
