2. Grid Laboratory Uniform Environment (GLUE)
collaboration effort focusing on interoperability between the US Physics Grid Projects and the European ones
Targeted for core grid services
Preserving coexistence for collective services

5th EU-DataGRID Conference

3. 5th EU-DataGRID Conference
Summary
Service/Resource Discovery
Authorization services (from VO LDAP to VOMS)
Common software deployment procedures
IST2002 and SC2002 joint EU-US demos
5 September 2002
5th EU-DataGRID Conference

4. Service/Resource Discovery
CE, SE and NE published in Globus MDS
Same technology, different schemas
Integrating schemas?
Not really! More data modeling and a new schema
Modeling guidelines:
Both detailed and aggregate hosts info
service-oriented view
CIM model
Transition: Element -> Service (CS, SS and NS)

7. 5th EU-DataGRID Conference
Network Service
Work will start as soon as GLUE group approves SS Schema (hopefully by the next week)

5th EU-DataGRID Conference

8. GLUE schema – CS implementation status
Conceptual model: stable
Schema implementation:
Ready (missing transition to service)
Recently added file system info and schema vers.
Information providers:
from EDG ready by 15th Sept
CS+Cluster+Subcluster info (no detailed host info)
Simpler case: CS on top of 1 cluster, 1 subcluster
We can use the monitoring framework (Netsaint&Nagios) to inject host info in the MDS
From Globus ready by 20th Sept
CS+Cluster+Subcluster+Host info
Simpler case: CS on top of 1 cluster, 1subcluster, 1 host
They are working on Ganglia info providers to manage multi-host case
Release: GLUE schema 1.0
only CS schema will be delivered with GT2.2 (20th Sept)

5th EU-DataGRID Conference

9. GLUE schema – SS implementation status
Conceptual model: the presented one has been discussed yesterday, seems to meet all the requirements
Schema implementation:
Raw one at work, as soon as we agree on the conceptual model, just a couple of days to issue the new one
Information providers (EDG):
To be done
Release: in GLUE schema 1.1
Will be delivered in GLUE

10. 5th EU-DataGRID Conference
GLUE Testbed

5th EU-DataGRID Conference

11. GLUE Schema – EU deployment
@CNAF-BOLOGNA
Static CS example working at grid006f.cnaf.infn.it
Moving to EDG 1.2 release
Adding final CS schema and info providers
Configuring RB for testing
Configuring GIIS
@PADOVA
Already moved to EDG1.2
Last CS schema and static example configured

5th EU-DataGRID Conference

12. GLUE Schema – US deployment
Top level GIIS to be updated with Glue Schema 1.0
GRIS with the current Glue Schema on MDS 2.1 and static data to be upgraded to MDS 2.2 and Globus Info Provider
5 September 2002
5th EU-DataGRID Conference

13. R-GMA implementation and interoperability with MDS
Service/Resource Discovery and GLUE schema
R-GMA implementation and interoperability with MDS
The UML description of the schema is implementation-independent
Will be used for schema implementation in R-GMA by WP3
Info providers can be easily adapted

14. Authorization services from VO LDAP to VOMS
EDG Tools proposed for use to iVDGL collaborators
VO LDAP server
VO GroupMAN
edg-mkgridmap
Work in progress…
VOMS under study by iVDGL collaborators
EDG WP2 security working on integration with OGSA architecture
iVDGL collaborators becoming aware of LCAS/LCMAPS
FNAL – Working on KCA/X509

15. Common software deployment procedures
Goals:
Contribute to a distribution that:
Is EDG and VDT compliant (can be included in VDT/EDG)
Includes main EDG and VDT components
Enforces common flexible configuration rules
Allows for interoperation of testbeds
Plan:
Distribute EDG CA (End of September, edg-release new schema)
Distribute EDG Replica Catalogue with GSI
Distribute UI, RB, JSS, L&B as “standalone” components Distribute information providers if requested
Propose a configuration strategy to both VDT and EDG
Work on a common EDG-VDT versioning strategy
Helping experiments with software distribution
(CMS/ATLAS PACMAN distribution)

16. Data Movement and Management
It is part of GLUE phase II.
Setting up of working groups in progress with involvement with EDG/WP2.
The existing collaboration between the Globus Team and EDG/WP2 is a good starting point.
Experiment requirements drive the effort.

5th EU-DataGRID Conference

17. 5th EU-DataGRID Conference
Joint EU-US grid demos
IST November, Copenaghen
SC November, Baltimore
Goals:
Basic collaboration between European and US grid projects
Interoperability between grid domains for applications submitted by users from different virtual organizations
Controlled use of shared resources subject to agreed policy
Integrated use of heterogeneous resources from iVDGL and EDG testbed domains

18. 5th EU-DataGRID Conference
Joint EU-US grid demos
Hardware definition in progress.
First simple sumission tests in progress.
Work on infrastructure and application demos as much as
possible before the middle of September.
Joint Task force in Chicago September, 2002
