3. Grid Resource Management:
Challenging Issues
•Authentication (once)
•Specify simulation
(code, resources, etc.)
•Discover resources
•Negotiate authorization, Domain 1
acceptable use, Cost, etc.
Domain 2
•Acquire resources
•Schedule Jobs
•Initiate computation
•Steer computation
•Access remote data-sets
•Collaborate on results
