9. Welcome to Geekland!

10. Large Linux clusters

11. PVM (parallel virtual machine) MPI (message passing interface)

12. 20%

13. 2000

15. What is grid computing?

16. Developing middleware which schedule computational intensive tasks on heterogeneous resources

17. grid middleware Resource Resource Resource

19. No modification required

20. No central component

21. Globus (the Windows ™ of grid computing) Globus Globus

22. Problems

23. user authentication missing libraries not running scripts resource discovery hard to deploy and maintain obscure protocols description of job/resource scheduling

24. Me vs Globus

25. 2002

26. “Everybody have own grid”
