2. Summary Activity Goals Planning and Resources Results achieved so far
Issues
Conclusions and Future Directions

3. Activity Goals / 1
The first goal is to analyze the emerging Grid standards related to Job submission and monitoring
JSDL (Job Submission Description Language), an XML notation for describing jobs
BES (Basic Execution Service), a WebService- based interface to Computing Elements
Extensions to the official specifications should be developed whenever necessary, in order to accommodate OMII-EU needs
JSDL provides built-in extension mechanisms

4. JSDL and BES Client Job 1 JSDL Job 2 JSDL BES interface BES interface
CREAM CE
UNICORE CE
GLOBUS CE

5. Activity Goals / 2
The second goal is to implement these technologies (plus identified extensions) within OMII-EU partner's infrastructures
GLOBUS
gLite/EGEE
UNICORE

6. MJRA1.10 OMII-Europe supports BES plus required extensions
Planning
We are
here
DJRA1.9
DJRA1.10 M6 M9
M12
M18
M20
M23
MJRA1.7 Definition of the required extensions needed to JSDL to satisfy OMII-Europe requirements
MJRA1.8 GridSAM integration into UNICORE: architecture and implementation available
MJRA1.9 Implementation of JSDL into OMII-Europe middleware together with the extensions identified
MJRA1.10 OMII-Europe supports BES plus required extensions
MJRA1.17 BES will be evaluated with respect to its adoption in the middleware of the OMII-Europe partners

7. Resources Funded Effort INFN 0.9 FLE 0.15 FZJ 0.05 Unfunded Effort
UEDIN 1.0
SOTON 0.5
UCHIC 0.5
UWM 0.25

8. Activity Status Held (mostly) regular monthly phone meetings
Interaction by phone, mailing list and wiki
First results: MJRA1.7 draft document available
Analysis of JSDL, and definition of extensions for GLOBUS, UNICORE and gLite
First prototype of JSDL/BES support in the CREAM CE available
Hopefully will be demonstrated at SC'06 interop demo session
The wiki proved to be a very good collaboration tool.

9. Issues
The manpower is OK for now, but is likely to be insufficient for MJRA1.8, MJRA1.9 and MJRA1.10
Implementation of JSDL and BES appears challenging
Specifications contain errors/typos (esp. BES, which has not been finalized yet)
Tools support for Web standards (WSDL/XSD/...) is far from complete
Interoperability issues for code produced by different tools (e.g., AXIS vs gSoap vs .NET vs...)
First problems arose while trying to implement JSDL/BES in the CREAM CE for the SC'06 interop demo

10. Conclusions The JRA1/Job Submission activity is going on regularly
Interaction using phone meetings, mailing list and wiki
Implementations of JSDL and BES will probably be less easy than foreseen
