4. gLite users Through the gLite 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

5. gLite middleware status
Operating System
User Interface and Worker Nodes ported to Scientific Linux CERN 4
All other modules/services still running under SLC 3
gLite Version
The current (Feb 5 , 2007) version is Update 13
moved away from a “Big Bang” release
updates for each component released individually
Outstanding bugs & issues
Currently 23 outstanding bugs and issues monitored

6. EGEE SA2/EUChinaGRID WP2/ETICS FtF Meeting – Feb 19-20, 2007 , Roma

7. LCG Pre Production Service
Latest gLite is deployed one the LCG Pre-Production Service
22 active sites
monitored trough SAM
CiC (Communication Interfaces for Central operations) –on-Duty send reports on PPS status to the ROC
Global User Support through the GGUS portal

8. LCG Pre-Production
Service

9. gLite developments Porting to Scientific Linux CERN 4.0 in progress
WNs already moved to SLC 4.0
All other gLite services still built for SLC 3
SLC 4 release will be called gLite 3.1
Porting the gLite middleware (JRA1) to IPv6:
Developers aware of this need
Formal commitment to the issue
No concrete timescale defined
Other matters ( porting to ia64 and SLC4) came first
EGEE SA2/EUChinaGRID WP2/ETICS FtF Meeting – Feb 19-20, 2007 , Roma

10. further gLite developments
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 gLite 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/gLiteCE
Complete support to SRM v2.2
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 EUChinaGrid on IPv6 compliance
EGEE SA2/EUChinaGRID WP2/ETICS FtF Meeting – Feb 19-20, 2007 , Roma

11. glexec 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 SA2/EUChinaGRID WP2/ETICS FtF Meeting – Feb 19-20, 2007 , Roma

12. Summary gLite 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 gLite issues
There’s no well defined timeline for the porting to IPv6
just a formal declaration of interest from JRA-1 still 
interesting developments are coming in all its components
gLite is still a moving target
