QMUL 28th June 2006

OverviewOverview

• All projects moving towards Service Phases– LHC experiments engaged in Service and commissioning

challenges– BaBar has grid simulation service– D-Zero delivering simulation, reconstruction and analysis– QCDGrid devloping and serving a community

• Headline issues– Tier 1 resources were insufficient in 05Q4 and 06Q1

• Some improvements now• How do we handle an experiment requesting an incompatible

system?– Data movement and managementis the current hot topic

for the LHC experiments• FTS response• LFC performance

ATLASATLAS

• Focussed on the ATLAS Distributed Analysis and the GANGA front end.

• Critical path• Significant feedback from early adopters rapid feature

enhancements in 06Q2. • The major sticking point is the deployment of the ATLAS Distributed

Data Management. – This is well integrated into the OSG sites (reflecting the origin of the

developer effort), but has proven more problematic in the LCG. • The DA effort has inevitably reduced the ATLAS input into the

Production tools– GANGA is now being taken-up by the production team as their front-

end. – ATLAS-wide deficiency in production tools; other FAs have been asked

to address this as well.• On hardware, the shortage of Tier 1 capacity, and especially the

reduction of disk capacity, caused significant problems. Tier 1 activity at RAL effectively stopped for 10 days because of shortage of disk space. Lancaster has been an effective temporary relief site. .

GANGAGANGA

• Tensions from serving two masters reduced• Release with job-building delivered in March

2006; this is later than planned• Release to support a range of application) is

changed to be due in October 2006, keeping in step with the Data Challenge release cycle. – Delayed deliverable will take on-board some

metadata access secondary deliverables. • End-user feedback from LHCb is good. • The ATLAS situation is not so good, as the

DDM delays (see above) have restricted the usability. This is a matter of urgency for 06Q2.

LHCbLHCb

• Excellent reporting• The ARDA metadata interface • Significant testing and feedback, and is fully

deployed and reported. (3.2.2 complete). • AMGA based version under development,

along with a GANGA plug-in to use it. • Other metadata interfaces, including AMI

from ATLAS have been • A new DIRAC release streamlines both

production and analysis jobs, and security has been enhanced; the release completes 3.3.11.

CMSCMS

• Some changes in deliverables because LCG will now handle low-level data transfers & architectural changes in BOSS that no longer split job preparation from monitoring and tracking.

• Big activity in SC exercises. Tim Barass has been very active, but he has left for a job outside of HEP.

• IC have been working on an XML-based architecture prototype for BOSS. However, the project leader has suspended the line of development, and IC is mow working on the CLI and API.

• There have been problems with the PhEDEx deployment at IC, now fixed; other important services have been deployed.

• Would still wish to see if there are common tools/projects possible

BaBarBaBar

• Uneven reporting here• The simulation reporting is skeletal! to say

the least. The simulation production seems on track however.

• A new temporary hire at SLAC will add to the analysis effort. Analysis commentary is long but ‘undigested’

• More on technologies used would help

SAMGrid/D0SAMGrid/D0

• RunJob deliverables 4.2.310-13 have been completed but not yet demonstrated.

• The full chain tests were expected in April.• The UK RAC has been working well, although

manual submission has been required as the automated interface, which was just being rolled-out at IC at the end of the quarter.

• The associated monitoring deliverable 4.2.9 is completed.

QCDGridQCDGrid

• QCDGrid releases in October 05 and May 06– October release includes significant QCDML

enhancements• Lots of work on implementing local

instances of ILDG Metadata catalogue interface as a web service– Some local difficulties bring in UK resources

• Major review of support systems • Still question of whether we can share

common technologies here

PhenoGridPhenoGrid

• No deliverables were due this quarter.

• There was a release of GENSER containing Herwig++

• Substantial progress on Herwig++ / FORM job submission

• Progress now being made, after a difficult 05Q4

Portal/MonitorPortal/Monitor

• Monitor – Displayed at Supercomputing 05, CHEP06– New monitor version– 3-D graphics, Google-map functionality

• Portal– Portal toolkit released in January – Lots of work on VOMS proxies– Support for CALICE and T2K

• Already good synergies with projects like ESLEA
