g. Lite users Enabling Grids for E-scienc. E • Through the g. Lite middleware a user can : – Register to a Virtual Organization § be authenticated, be authorized, get credentials for jobs and data transfers – Submit and Manage GRID jobs § Use JDL files via CLI or portals/GUIs, submit jobs or job collections, submit DAGs, submit parametric jobs, get job related information, cancel single jobs or sets/collections, retrieve the output § Require specific resources or input files for the jobs he/she’s sending § Automatically renew his/her proxy if required for long lasting jobs – Transfer files from different locations § from a WN to a Storage Element § From different Storage Elements based on different architectures – Register the produced or replicated files in a Catalog for his/her VO § Directly or indirectly query this file catalog – Query the GRID information system and get a snapshot of the available resources EGEE-II INFSO-RI-031688 EGEE SA 2/EUChina.

g. Lite middleware status Enabling Grids for E-scienc. E • Operating System – User Interface and Worker Nodes ported to Scientific Linux CERN 4 – All other modules/services still running under SLC 3 • g. Lite Version – The current (Feb 5 , 2007) version is 3. 0. 2 Update 13 § moved away from a “Big Bang” release • updates for each component released individually http: //glite. web. cern. ch/glite/packages/R 3. 0/updates. asp – Outstanding bugs & issues § Currently 23 outstanding bugs and issues monitored https: //savannah. cern. ch/bugs/index. php? go_report=Apply&group=jra 1 mdw&func=browse&se t=custom&msort=0&report_id=144&advsrch=0&summary=&assigned_to=0&priority=6&seve rity=0&submitted_by=0&resolution_id=0&category_id=0&status_id=1&bug_id=&history_sear ch=0&history_field=0&history_event=modified&history_date_dayfd=19&history_date_monthf d=6&history_date_yearfd=2006&chunksz=50#options EGEE-II INFSO-RI-031688 EGEE SA 2/EUChina.

LCG Pre Production Service Enabling Grids for E-scienc. E – Latest g. Lite is deployed one the LCG Pre-Production Service § 22 active sites § monitored trough SAM https: //lcg-sam. cern. ch: 8443/sam-pps/sam. py? sensors=CE § Ci. C (Communication Interfaces for Central operations) –on-Duty send reports on PPS status to the ROC § Global User Support through the GGUS portal www. ggus. org EGEE-II INFSO-RI-031688 EGEE SA 2/EUChina.

g. Lite developments Enabling Grids for E-scienc. E • Porting to Scientific Linux CERN 4. 0 in progress – WNs already moved to SLC 4. 0 – All other g. Lite services still built for SLC 3 § SLC 4 release will be called g. Lite 3. 1 • Porting the g. Lite middleware (JRA 1) to IPv 6: – Developers aware of this need – Formal commitment to the issue § No concrete timescale defined § Other matters ( porting to ia 64 and SLC 4) came first EGEE-II INFSO-RI-031688 EGEE SA 2/EUChina. GRID WP 2/ETICS Ft. F Meeting – Feb 19 -20, 2007 , Roma 9
further g. Lite developments Enabling Grids for E-scienc. E • Complete the migration to VDT 1. 3. x • Complete the migration to fully supported 64 -bit architecture • Improve manageability (start/stop/. . . and standard log files) – Reduce dependencies on external components to make g. Lite more “Lite” • Hooks for local/global monitoring (new Monitoring working group) • Continue work on making all services VOMS-aware – Including activities in the Job Priorities WG • Decouple bulk submission from DAGMan • Support the deployment of Job Provenance to optimize the use of L&B • Support for all LRMSs present on PS in BLAH/g. Lite. CE • Complete support to SRM v 2. 2 • Complete the new Encrypted Data Storage based on GFAL/LFC • Complete and test glexec on WNs • Increase the use of Service Discovery in all services • Collaboration with EUChina. Grid on IPv 6 compliance EGEE-II INFSO-RI-031688 EGEE SA 2/EUChina. GRID WP 2/ETICS Ft. F Meeting – Feb 19 -20, 2007 , Roma 10
glexec Enabling Grids for E-scienc. E • glexec is a thin layer to change unix credentials – – much simpler than the gatekeeper doesn’t require to run as root all the time based on GRID identity and attribute information takes in input § a certificate chain with VOMS extensions § user program name and arguments to run – checks authorization – aquires local credentials – enforces the local credentials on the process • glexec deployment on WNs is related to the VO handling of pilot jobs § pilot jobs are small scripts downloading real jobs EGEE-II INFSO-RI-031688 EGEE SA 2/EUChina. GRID WP 2/ETICS Ft. F Meeting – Feb 19 -20, 2007 , Roma 11
Summary Enabling Grids for E-scienc. E • g. Lite is about to be ported to SLC 4 and 64 -bit • will continue to be deployed on the LCG PPS for the experiments and applications to experience its latest version – useful to keep an eye to understand immediatley latest g. Lite issues • There’s no well defined timeline for the porting to IPv 6 – just a formal declaration of interest from JRA-1 still • interesting developments are coming in all its components – g. Lite is still a moving target EGEE-II INFSO-RI-031688 EGEE SA 2/EUChina. GRID WP 2/ETICS Ft. F Meeting – Feb 19 -20, 2007 , Roma 12
