14 July 2008 - Agenda, Minutes
Quiet week with
small number of alarms and no outstanding issues. Italian ROC produced a
detailed report, passed to WLCG management, concerning their recent
problems with power.
7 July 2008 - Agenda, Minutes
Semi-Transparent
Interventions - The Italian ROC questioned the correct procedure for
advertised transparent interventions that, because of unexpected issues,
change status during the execution and become not transparent. To be
considered and discussed with the GOCDB staff.
FTS Configuration
Completed - The last of the WLCG Tier-1 sites, BNL and Fermilab,
confirmed that their FTS servers had been reconfigured to zero retries for
the LHC VOs.
30 June 2008 - Agenda, Minutes
CREAM CE Testing
- Pre-production testing of the CREAM CE is now well under way.
Feedback on Proxy
Renewal Issues - Requests were made for comments on the proxy renewal
daemon crashing with the recently released VOMS servers.
Base Storage
Services Report - A report was given on the status of base storage
services needed at sites.
LFCs on GOCDB and
BDII - ATLAS requested gstat should highlight discrepancies between
LFCs in GOCDB, but not those in BDII.
23 June 2008 - Agenda, Minutes
TAU-LCG2 Closed-
TAU-LCG2 site in Israel was closed.

16 June 2008 - Agenda
9 June 2008 - Agenda, Minutes
CE Node Types -
It was reported that while the lcg-CE SAM tests can be used unmodified on
the CREAM CE. A new node type will be created so that the results and logs
can be distinguished.
ACBR FAQ Needed
- Again sites are asking how to publish ACBRs (Access Control Base Rule)
for read-only access to production queues. It seems there are no clear
concise instructions and should be provided urgently.
2 June 2008 - Agenda, Minutes
Temp Cleaning Script
Issues - LHCb reported that the scripts cleaning temporary areas
(“tmpwatch”) do not work well. Jobs unpacked in /tmp were deleted at the
very first run of tmpwatch.

LCG
Services Weekly Report -
J.Shiers presented a summary of status and progress of the LCG Services.
This report covered the last two weeks. Notes from each daily meeting can be found from these
pages: Link
Accounting
Installed Capacities - F.Donno presented a
proposal for obtaining, in an automatic manner, the installed CPU and SE
capacity at all sites. The goal is to provide the management with
information about installed capacity (per VO) with information about actual
resources usage (per VO), focusing on CPU and SE resources.
Proposal
for CPU Benchmarking - H.Meinhard summarized the work
of the HEPiX CPU Benchmarking working group and a proposal for a future CPU
unit to use in the WLCG accounting, pledges, etc.
MonALIsa
Accounting - H.Marten reported on the
comparison between accounting done by ALICE with MonALIsa and the one by
with the PBS batch system at GridKa.
User
Space Management - B.Panzer drafted a first
proposal on how to tackle the support end-user analysis.
24 June 2008 - Agenda, Minutes
LHCb
Request of Using Pilot Jobs - Ph.Charpentier distributed a note about allowing LHCb to use
multi-user pilot jobs at the Tier-1 sites.
LCG
Services Weekly Report - J.Shiers presented a summary of

High
Level Milestones Verification - I.Bird
asked for a final verification of some HL Milestones before the LHCC Review
of next week.
Status
of OSG RSV test and Equivalence to SAM - D.Collados proposed a set of critical tests for OSG
(RSV_Crit_Tests) and R.Pordes reported the status of the OSG RSV milestones present in
the HL Milestones dashboard.

CCRC’08 is now formally over
– leaving behind a good service base on which to steadily, but
non-disruptively build. We will have an extended post-mortem next week
(Link) – today we will (briefly) summarize the key events of the last week
of the May run together with some initial lessons
There were
several discussion and emails on the accounting reported by ALICE on the
week before.

Schema Evolution in ROOT- The ROOT
release scheduled for 26 June will not include the new extension of the
schema evolution. The introduction of the new schema evolution
functionality will be done by the end of August. The production release
with these features is expected in December 2008.
Configuration Changes - LCG_54g has
been released, LCG_55 can go immediately undoing the upgrade of the version
of Boost that did not work straight away. Boost 1.35 will be added in the
"dev" nightly slot to prepare for its inclusion in future configurations.
Geant4 Beta Release - There will
not be a new production version of Geant4 in June this year. There will be instead a beta release
(9.2-beta) which will be made available for testing to users at the
beginning of July.
29 May 2008 – Minutes
Changes to POOL - Report on
the ongoing effort for reducing the complexity of the POOL package; summary
of series of meetings with representatives from the experiments that has been
held to know about their use of POOL.

decided for the moment the usage of the gcc 4.1 compiler for the SLC5
platform. It is the default compiler version for SL5.
CernVM
Release0.5 - The new 0.5 release of CernVM is under preparation;
the release includes small fixes and extra packages on request from LHCb,
addressing SLC4/5 compatibility libraries.
