10 June 2009 GDB Meeting Agenda
Middleware and CREAM Update A.Unterkircher presented the
status and progress of the updated expected for end of June and N.Thackray
presented the update of the CREAM CE testing and deployment.
STEP09 Progress J.Shiers presented a summary of the Scale
Test for the Experiment Program (STEP09). The goal was to test the readiness
of the WLCG Sites under realistic use conditions from the LHC
Experiments. The presentation shows
the main achievements reached and the issues still to address. A Post Mortem Workshop, to discuss the
lessons learned, took place on the 9-10 July 2009 at CERN. Link
HEPiX Summary M.Jouvin provided a summary of the HEPiX
meeting in Umea focusing on virtualization, benchmarking, file system and
data centers in High Energy Physics.
SL5 for the Experiments and the LCG Meta-package P.Mato
summarized the requirements of the Experiments in order to migrate their
Physics Applications to SL5. O.Keeble presented the idea of a deployment
meta-package that would groups all needed packages under a set of package
dependencies for the WLCG software stack.
User Analysis Support M.Lamanna chaired a discussion on
support for user analysis and presented the tools currently used in the
Experiments for Sites availability, robots for regular job submission on
selected datasets and load generators.
9 June 2009 Pre-GDB Meeting Agenda

Tier-2 Sites. The roadmap and support models of dCache, DPM and StoRM were
presented and discussed. The Experiments and the US Tier-2 Sites also
provided their input.
13 May 2009 GDB Meeting Agenda
GGUS Structure and Workflow Changes M.Dimou presented the
latest improvement in the GGUS user support system and the changes in the
EGEE support procedures.
Updates on Storage - R.Graciani Diaz presented the LHCb tests and
G.Lo Presti the SRM Usage Statistics.
SL5 Requirements P.Mato presented the Experiment requirements
for SL5 deployment and A.Graeme his experience in memory usage in SL5 64
bits mode.
Experiments Data Flows and Use Cases ATLAS, CMS and LHCb
presented the data flows and requirements coming from the use cases
described in their Computing Models and that they expect to be supported by
the WLCG Sites. .
In addition there were updates on
the Pilot Jobs and CREAM CE status and progress.
12 May 2009 Pre-GDB Meeting Agenda
Support for WLCG after EGEE - Each Tier-1 Site presented their
plans for supporting the WLCG Operations after the end of the EGEE project.
