GDB Meeting Agenda
SL5
Deployment at Sites J.Gordon summarized the
situation of the SL5 deployment at several WLCG Sites.
Middleware
Updates - A.Unterkircher presented
the status of the migration of the Worker Node to SL5. He also summarized the upcoming released
of several gLite and storageware packages.
CREAM
Deployment at Sites A.Retico presented the
status of the deployment of the CREAM CE.
Experiments. In particular ALICE has asked that CREAM is deployed at
all their Tier-1 and Tier-2 Sites.
LHC-OPN
Update W.Salter presented the
status and progress of the LCG Optical Private Network which is connecting
the Tier-0 and Tier-1 Sites of the WLCG.
He also presented the recent modifications that were agreed and
executed on the OPN.
Experiments
Tests in SAM J.Shade presented the
strategy for moving SAM from a centralised infrastructure at CERN to a distributed framework based on Nagios.
He also described how Experiments tests and results will be integrated in
this new scenario.
ALICE
Operations P.Mendez-Lorenzo presented
the priorities of the ALICE requirements. In particular ALICE needs SL5 and
CREAM installed at all ALICE Sites.
Virtualization
for WLCG T.Cass proposed a strategy
for introducing virtualization in the WLCG infrastructure in order to
enable experiments/users to choose the environment for their jobs execution
and ensure sites have control and traceability over resource usage.
WLCG
Technical Forum M.Litmaath presented the
newly launched working group in charge of clarifying the areas for
improvement among the WLCG stakeholders (Sites, Experiments, Software providers)
in order to form a common WLCG position w.r.t. EGEE, EGI, OSG and other
software and hardware providers. In the longer term will represent also the
WLCG needs w.r.t. services and middleware, in term of sustainability and
evolution of the existing middleware in the light of changing technologies
and the experience gained.
8 July 2009 GDB
Meeting Agenda
Security
Policies D.Kelsey presented the
status and progress of the Joint Security Policy Group and of four document
under final approval call regarding: VO Registration, VO Management,
User-level accounting, VO Portals and Security Incident Response.
SCAS/glExec
and Pilots Jobs M.Litmaath presented the
open issues with SCAS, glExec on the Worker Nodes and the Pilot Jobs
frameworks from the Experiments.
Discussion
on Chimera Migration M.Jouvin presented the
reaction of the Sites to the advice to upgrade dCache from PNFS to Chimera.
The Tier-1 Sites running dCache replied that they cannot migrate to Chimera
before data-taking in 2009, and maybe 2010.
SL5
Migration and Middleware Updates A.Unterkircher presented the status of the migration of the Worker
Node to SL5. He also summarized the
upcoming released of several gLite and storageware packages.

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

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 Storage Support The meeting focused on storage at the
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.
16 September 2009 Minutes
Move to WMS.3.1.21-0 - Call to encourage sites to move to the most recent version of WMS
available in gLite 3.1, which corresponds to gLite-WMS 3.1.21-0 in the
gLite repository.
Security Patches - Last month several alerts were sent to all Sites about critical
security vulnerabilities in the Linux kernel. It is essential to actively
and urgently ensure all the Sites have applied these security patches.
7 September 2009 Minutes
DPM Move to SL4 - Last reminder that the default DPM used for SAM tests were be
upgraded to SL4 on the 7th of September and that sites with obsolete client
software will start failing tests.
31 August 2009 Minutes
SAM
MPI Tests - Despite the fact that
there are MPI deployment problems with the gLite SL5 Worker Nodes, the SAM
MPI tests can be enabled because the sites published information system is
interrogated first to check for MPI support at each given site.
24 August 2009 Minutes
Default
DPM on SL4 - Last reminder that the
default DPM used for SAM tests will be upgraded to SL4 and that sites with
obsolete client S/W will start failing tests. There are still 11 CEs
failing.
SAM
MPI Tests Validation - At the TMB on 05/08/2009
it was agreed that SAM MPI tests should be re-instated and results followed
up. They will go through validation, for a shorter period, as they had gone
through validation before. All Sites are requested to check the validation
results and follow up.
Tier-2
Sites Asked to Move to SL5 - WLCG
MB agreed on 4th of August to ask for the SL5 migration at all Sites, including
the Tier-2 Sites. A web page is available to provide pointers to the
relevant information to support the migration, including links to the
necessary packages. (Link). It is understood that
the Experiments are all ready and able to use SL5 resources.
3 August 2009 Minutes
DPM
on SL3 Tests Will Fail -
Because of the imminent upgrade to SL4 of one of the services (DPM) used to
submit SAM tests sites still running on SL3 (no longer supported) would
start failing the tests. This effect can already be seen from the SAM
validation instance. All sites filing the tests in the validation instance
should upgrade their WNs to the last version ASAP and ROCs are invited to
monitor this process. The switch of the SAM DPM production is scheduled for
the 10th of August, less than 2 weeks from now.
27 July 2009 Minutes
BDII Patch Needed
for SL5 Sites - Sites running top-level BDIIs on SL5 are required to
install the latest patch included in gLite 3.2 update 0.4.
20 July 2009 Minutes
Incompatibility
between VOMS and mod_gridsite - The UK/Ireland region highlighted an
incompatibility between VOMS when configured in a particular style and with
mod_gridsite as part of the WMS. This is being investigated now by the EGEE
EMT.

SL5
Deployment - Some Sites have asked for
clarification about the SL5 deployment. J.Gordon asked that the MB approve
and requests the move to SL5 to the Sites. Experiments want to have
initially a separate CE in order to test SL5 nodes at a given Site. The
Experiments will then ask for the change in proportion of SL4/SL5 nodes at
each Site.
