GDB Meeting Agenda
New
CPU Benchmarking G. Merino presented the
proposal for the transition to a new CPU Benchmarking unit. The old
benchmark (SPECint2K) is not used by hardware vendor, therefore all CPU
resources of WLCG should be expressed in the new CPU unit (e.g. for
Experiments requirements, Sites pledges, accounting, etc).
Grid Configuration Data J. Casey presented the current status of the information stored in
the GOCDB and BDII databases. He also proposed how to improve the current
situation avoiding duplication of information and how to better handle
static and dynamic grid information.
Update
on gLite Middleware N.Thackray presented the
status and progress of testing and deployment of the CREAM CE, of the SL5
certification of gLite and of the development of SCAS. A. Unterkircher presented how to better
manage changes in order to allow faster deployment of new releases and
rollback in case of problems.
GLUE
2.0 L. Field explained the
basic ideas behind the GLUE schema descriptions, the experience gained in
the first 4 years of using GLUE and the improvements in GLUE version 2.0.
Other presentations covered
reports of the activities of the LHC Experiments during the Christmas shutdown, the progress
of the Worker Node and VOM(R)S WGs and the Ticketing
Routing between OSG and GGUS..
10 December 2008
GDB Meeting Agenda
GGUS
Tickets to OSG Sites M. Dimou reported on the
strategy for directly routing to OSG the GGUS tickets that concern issues
with OSG hardware and software resources.
Installed Resource Collection F. Donno presented her proposal
about reporting installed capacity through the Information System for
Computing and Storage.
Policies Updates and Operational Security D. Kelsey presented
the main updates to the security and policies documents. R. Wartel
presented the operational aspects of monitoring, logging and preventing
security incidents.
Job Efficiency U. Schwickerath
presented the status of job efficiency at CERN; and the strategies that
will be implemented in order to improve the way jobs are monitored.
Other presentations covered
reports of the ALICE
Experiences with CREAM CE, the Middleware Updates and the OSG
Campus Grid.
26 January 2009 Minutes
New
Version of CREAM CE - A new version of CREAM CE
was included in the gLite 3.1 update 39 and released last week.
Installed CA
Verification - JSPG recommends that SAM tests should only check that
the CAs installed are up-to-date.
19 January 2009 Minutes
LHCb
Problems at CNAF - For LHCb CNAF is currently
unusable and will be dropped from their FEST09 exercise.
BDII
Certification The new
release of BDII is in certification (to be installed at your own risk).
CNAF, GRIF & AEGIS will keep testing it until the official release is
scheduled.
12 January 2009 Minutes
SL5 WN Testing The pilot service of the SL5 WN: is
in progress. LHCbs tests on the pilot installation pointed out some issues
with the gssklog mechanism when submitting from DIRAC3. The issue
apparently appeared with the newer version of VDT distributed in the WN and
is under investigation.
8 December 2008 Minutes
New version of CREAM - New version
of CREAM available for pilot testing in Padua and Karlsruhe.
SL5 WN at CERN A pilot installation
was prepared. Some Information System conflicts with differing
interpretations of pre-production or production status.
WMS Configuration - WMS has bugs
preventing jobs being steered purely by JDL. The system configuration file overwrites
local configuration, thus compromising the DIRACs use of the feature.
1 December 2008 Minutes
VOMS Pilot -
Requested from LHCb, sites should deploy the VOMS role pilot.
GLite 3.1-37 to
Production - gLite 3.1 Update 37 was released to Production today. The
fix to avoid recursive publishing had to be re-instated.
24 November 2008 Minutes
BioMed VO Issues
- A number of regions reported high load and apparently non optimal usage
of resource by the biomed VO which is currently running some challenges.
E.g. High load LFCs in France. Multiple Worker
Nodes in the UK accessing identical files at remote SEs.
Hydra testing -
ROCs are asked if they wish to help with certifying, testing or using
HYDRA.
17 November 2008 Minutes
CREAM CE Pilot
The pilot testing of the CREAM CE was extended to 16th December.
GOCDB Cleanup -
GOCDB service name cleanup will take place on Wednesday.
SRMV2 SAM Tests
- LHCb and ATLAS stated that they are looking forward to have SRMv2 tests
accounted in the availability reports.

27 January 2009 Agenda, Minutes
WLCG
Operations Weekly Report H.
Renshall presented the summary of status and progress of the LCG Operations
since last MB meeting. The problems remain heterogeneous and without a
predictable pattern; however, the resulting service failures are usually of
short time duration. Link
New
CPU Unit - G. Merino presented the
document explaining how to organize the transition from the old (SPECint2K)
to the new unit for CPU benchmarking (called HEP-SPEC06).
Comments
on VO SAM tests The 4 LHC Experiments
commented the availability and reliability results of their tests on the
Tier-1 Sites.
CMS
Quarterly Report M. Kasemann distributed
the CMS quarterly report for 2008Q4.
20 January 2009 Agenda, Minutes
WLCG
OPS Weekly Report J. Shiers presented the
summary of status and progress of the LCG Operations since last MB meeting.
The daily meetings summaries are always available: Link
ALICE
Quarterly Report L. Betev presented the ALICE
quarterly report for 2008Q4.
LHCb
Quarterly Report P. Charpentier presented the LHCb quarterly report for 2008Q4.

Resources
Procurement in 2009 The MB discussed the
changes in planning of procurements in 2009. Based on the information at
the time it seemed unreasonable to keep to the agreed resource deployment
schedule. The workshop in Chamonix (Feb 2-6) will define the LHC schedules
for 2009 and 2010 in detail.
ATLAS

SLC5 on LXPLUS -
Concerning the deployment of SLC5, CMS has a problem with changing the
lxplus alias as it had been initially announced.
LCG_56 Configuration
The AF discussed the remaining issues needed to be solved before the
release. Release is still expected by the beginning of February.

reported about the recent review of Castor and its plans for the future.
Detailed information and pointers to presentations are in the minutes.
SLC5 migration
The AF supported the proposal to not include CERNLIB as part of the SLC5
standard installation. A number of issues need to be understood about the
differences between gcc compilers by Red Hat and the ones currently in use.
Clarifications will be asked from IT/FIO in order to
understand the deployment plan for SLC5.
CLHEP 2.X Support
It was agreed that all the LCG Applications Area software should be
supporting the 2.X version of CLHEP and not only the version 1.X.
11 December 2008 - Minutes

S. Roiser reported on the status of the Grid client libraries for SLC5,
gcc-4.3 and Python 2.5 and the tests from the experiments.
Decided to include new version of CLHEP (1.9.4.2) in
LCG_56.

HyperNews to SharePoint S. Roiser reported that the migration of the
ATLAS HyperNews items to SharePoint is completed.
27 November 2008 Minutes
