2. EU project: RIO31844-OMII-EUROPE Normal gLite Job Submission Path UI WMProxy WMS CE Use r CREAM CE CE Condor CE Job entry points

3. EU project: RIO31844-OMII-EUROPE Observation Two different job entry points. Why? – CREAM can be used also outside the gLite infrastructure: it is a stand-alone service – WMS, on the other hand, offers additional functionalities (e.g., matchmaking, resubmission of jobs...) – Users not interested in using the WMS functionalities can submit directly to CREAM

4. EU project: RIO31844-OMII-EUROPE Same situation, with BES UI WMProxy WMS CE Use r CREAM CE CE Condor CE BES

5. EU project: RIO31844-OMII-EUROPE The actual situation is slightly different UI WMProxy WMS CE Use r Condor CE CE CREAM CE ICEJC+LM

6. EU project: RIO31844-OMII-EUROPE Speculation UI WMS Use r BES Connector CE CREAM CE BES CE Condor CE BES CE UNICORE CE BES WMProxy

7. EU project: RIO31844-OMII-EUROPE Issues That would need non negligible modifications to the gLite infrastructure – Discussion just started, outcome not obvious BES offers less features than the standard interface of CREAM and the Condor CE BES requires JSDL job descriptions; gLite uses classad-based JDL – Switching all gLite to JSDL not feasible – JSDL -> JDL translator already build – (subset of) JDL -> JSDL translator could be considered – JSDL submission from UI not trivial

8. EU project: RIO31844-OMII-EUROPE Proposed Activity Planning / 1 Short term goal: Get BES and JSDL working inside CREAM, UNICORE and GLOBUS CEs – Can this be done in a reasonable (<6 months) timescale? – A single BES-enabled client could then submit the same job to multiple BES-enabled CEs—exactly what the SC06 demo is about – Appears very useful to demonstrate the usefulness of BES and JSDL – Authentication/Authorization issues will be addressed by JRA3, and implemented when ready

9. EU project: RIO31844-OMII-EUROPE Proposed Activity Planning / 2 Long term goal: complete interoperability of different GRID systems? – “Plugging” whichever BES CE in existing gLite/Globus/UNICORE-based GRIDs – Should that be done in strict cooperation with JRA3/Infrastructure Integration? – Authentication/authorization issues will be addressed by JRA3/Security

10. EU project: RIO31844-OMII-EUROPE Planning M6M12M18 MJRA1.7 Definition of the required extensions needed to JSDL to satisfy OMII-Europe requirements MJRA1.17 BES will be evaluated with respect to its adoption in the middleware of the OMII-Europe partners 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 M2 0 M9M2 3 DJRA1.9 DJRA1.10 We are here
