2. Enabling Grids for E-sciencE EGEE-II INFSO-RI-031688 Motivation and Overview Motivation –UNICORE offers access to supercomputers, e.g. DEISA infrastructure –Several applications demand access to the EGEE infrastructure as well as supercomputers Overview –Introduction to UNICORE –Overview of interoperability environment –Example: job submission –Outlook 2

7. Enabling Grids for E-sciencE EGEE-II INFSO-RI-031688 Example: job submission gLite User Interface (UI) –standard job submission –JDL contains Requirements = other.GlueCEInfoLRMSType == "UNICORE“ gLite Resource Broker (WMS) –chooses the appropriate CE based on information from the BDII gLite CE –uses BLAHP (Basic Local ASCII Helper Protocol) scripts for submission to UNICORE –builds an xml file in UNICORE CLI (Command line interface) syntax –calls UNICORE CLI to build and submit the job (proprietary UNICORE5 Abstract Job Object) 7

8. Enabling Grids for E-sciencE EGEE-II INFSO-RI-031688 Example: job submission UNICORE Gateway –authenticates user based on VOMS proxy certificate UNICORE NJS –authorizes user based on VOMS proxy certificate and maps to the login name UNICORE TSI –executes UNICORE job, i.e. wrapper around gLite job gLite WorkerNode (on Target system) –executes gLite job 8

9. Enabling Grids for E-sciencE EGEE-II INFSO-RI-031688 Outlook Switching to gLite CREAM CE –BLAH scripts need to be adapted (minor changes) Switching to UNICORE 6 –UNICORE 6 command line client  input: JSON (JavaScript Object Notation) syntax  output JSDL (Job Submission Description Language) –BLAH scripts need to be adapted –UNICORE 6 Gateway user authentication based on proxy certificates (already implemented) –UNICORE 6 XNJS user authorisation based on proxy certificates (implementation ongoing) 9

10. Enabling Grids for E-sciencE EGEE-II INFSO-RI-031688 Outlook Switching to IBM systems –Porting of gLite WorkerNode ongoing Users –Wide In Silico Docking On Malaria (WISDOM) initiative –EU Fusion for ITER Applications (EUFORIA) project 10
