NAREGI Interoperability/Interoperation, Short Term Policy (for EGEE, GIN, and BES/ESI) May 2006 NAREGI-WP1 National Institute of Informatics

2 Interoperability: NAREGI Short Term Policy NAREGI has three interoperability/interoperation plans. Interoperation with EGEE (gLite) Discussed in CERN (March) and Condor Week (April) SC06 –Simple/Single Job (up to SPMD) –Bi-Directional Submission NAREGI  gLite:GT2-GRAM gLite  NAREGI:Condor-G –Exchange Resource Information GIN Interoperability (WS-GRAM) SC06 –Simple/Single Job (up to SPMD) –One way Submission (NAREGI  GIN) GIN  NAREGI is difficult to support in the current NAREGI implementation –WS-GRAM –Exchange Resource Information (depends on activity of Information Service Area) GIN Interoperability (BES/ESI) –Under study –Schedule is TBD

3 Interoperation with EGEE (gLite) gLite to NAREGI bridge NAREGI client lib ClassAd  JSDL NAREGI-WF generation Job Submission/Control Status propagation Certification ? NAREGI-IS [CIM] IS bridge gLite-IS [GLUE] GLUE  CIM Bridge-CE [JDL] Condor-G NAREGI-SS [JSDL] NAREGI-SC Interop-SC gLite-CE NAREGI GridVM JSDL  RSL Job Submission/Control Status propagation GT2 GRAM NAREGI Portal [JSDL] EGEE user NAREGI user gLite-WMS [JDL] Condor-G Adapter

4 GIN Interoperability (WS-GRAM) NAREGI-IS [CIM] IS bridge anotherGrid-IS [CIM or GLUE] GLUE  CIM anotherGrid [JSDL] GT4 NAREGI-SS [JSDL] NAREGI-SC Interop-SC anotherGrid-CE NAREGI GridVM JSDL  RSL Job Submission/Control Status propagation WS-GRAM NAREGI Portal another grid’s user NAREGI user WS-GRAM Sorry, One way now !! (Short Term )

5 Study: BES/ESI Interoperability ESIBESNAREGI SSSC Use JSDL ✔ *1 ✔ WSRF OGSA Base Profile 1.0 Platform ✔✔✔✔ Job Management Service ✔✔✔✔ Extensible Support for Resource Models ✔✔ Reliability ✔✔✔✔ Use WS-RF modeling conventions ✔✔✔✔ Use WS-Agreement Advance reservation ✔✔ Bulk operations ✔ Generic management frameworks (WSDM) Define alternative renderings Server-side workflow ✔ *1: Extended Comparison: Goals

State Model NAREGI state model is similar with BES state model

7 Interoperability: NAREGI Long Term Policy Support standard I/Fs for interoperability (BES/ESI etc.) Improve independency of Super Scheduler (SS) and Job Execution Service (SC) –SS Support job submission to other grids –Support execution services which have no advanced reservation capability Simplify input workflow –Separate user process workflow and service workflow Study: BES/ESI as SS I/F –Problem: No workflow I/F –SC Support job submission from other grids –Support non advanced reserved job submission –Improve job submission and advanced reservation I/Fs for upper layer »Reservation table synchronization etc. Study: BES/ESI as SC I/F –Problem: No advanced reservation I/F
