2. Some Grid Activities Griphyn iVDGL PPDG VDT EDG EGEE LCG ATLAS CMS
ARDA
GT-3 and Gt-4
NMI
OMII
Semantic Grid

3. Topics Covered File Transport Datasets (linked files) Data Management
Running and monitoring jobs
Data Provenance and Curation
Caching
Batch Processing – Monte Carlo and Data transformations
Physics Analysis
Collaboration

4. Structure of Grids
Grids are today structured as “services” – packaged distributed programs
System Services: Security, File and database access, Collaboration, Service catalog, Metadata repository, Notification, Fault tolerance
Application Services: Run a job, Define a PWA model, do a maximum likelihood fit
Condor and Globus are critical job scheduling/running services in early HEP Grids
All future Services will be built as Web Services
Grid Portals with component interfaces

6. Some Grid Activities in Detail I
Griphyn iVDGL PPDG VDT
Package Globus 2 and Condor
Deliver US counterpart to LCG
EDG EGEE LCG
Starting with Globus/Condor, deliver as Web Services with various enhancemed services as in metadata, security and caching
ATLAS CMS
Experiment specific software linked to ARDA
ARDA
EGEE led project to produce physics analysis (as opposed to batch processing system) Grid

7. ARDA

8. ATLAS CMS ARDA Integration

9. Some Grid Activities in Detail II
Globus Toolkit GT-3 and GT-4
Produce enhanced Web Services as OGSI (GT-3) or WSRF (GT-4)
Produce Grid Service version of Globus (GT-2)
NMI NSF Middleware Initiative
Package Internet-2 Security, Globus, Condor and Portal technologies
OMII Open Middleware Infrastructure Institute
Funded by UK e-Science program to produce generally useable Grid software
Semantic Grid
Support metadata about services and data (provenance)
Data curation uses to look after data – digital libraries
