Update 42 (scheduled for 23-MAR-2009) will include VDT 1.6.1 Release 9
which fixes a Globus bug that affects most m/w services.
GLite 3.2. Release - gLite 3.2
Update 01 (scheduled for 30-MAR-2009) will include new SL5 WNs
WMS Problems Reported by LHCb - LHCb
reported being affected by WMS problems
9 March 2009 – Minutes
Signed RPMs for gLite - gLite3.2 is
announced as the first version of gLite supporting signed RPMs.
Tests of LHCb Tier-1 Sites - LHCb is
doing extensive testing of GGUS alarm tickets against T1 sites.
2 March 2009 – Minutes
EGEE User Forum – The EGEE User Forum took place this
week in Geneva. Link
23 February 2009 – Minutes
SL5 64 Bits Worker Node - SL5 64 bit
worker node has been running at CERN for some time without problems. This
will be packaged and released as soon as possible.
32 bit versions of SL5 services will only be worked on
upon request and if there is sufficient effort. The preference is for the
SL5 version of the middleware to be 64 bit only.
BNL and FNAL Move to OSG - With BNL and
FNAL completing their move out of the EGEE infrastructure and into the OSG
infrastructure, a meeting has been set up to finalize the details of how
trouble tickets will be dealt with.

of status and progress of the LCG Operations. The daily meetings summaries
are available :Link
ATLAS 2009Q1 QR
Report – D.Barberis presented the 2009Q1 quarterly report for the ATLAS
software and services. And their planes for 2009.

2 April 2009 - Minutes
Migration from CVS
to SVN - Discussion on the CVS to SVN migration of experiments code
repositories. Changes in the priorities and plans from the experiments due
to the new LHC schedule.
SLC5 Migration
Issues - CERNLIB libraries has been re-compiled and tested by ATLAS.
New failures of the FIO provided SLC55 lxbuild nodes for the nightly build
service(s). Slow responsiveness. Released new version of gLite for SLC5 (64
bit)
Virtualization
Workshop - A lot of interest and nice feedback for both multi-core and
virtualization R&D activities at CHEP. Starting to prepare the workshop
on adapting applications and computing services to multi-core and
virtualization.
19 March 2009 - Minutes
Geant4 Patch
Released - A new Geant4 patch for 9.2 was released last Monday. CMS was
waiting for it. Both ATLAS and CMS are now aligned to the same version of
Geant4.
SLC5 Migration
Issues - One of the biggest problems for the SLC5 migration is being
the slow acquisition and correct configuration of the lxbuild nodes. The
CERNLIB libraries need to be re-compiled with -fPIC to avoid the problem
with SELinux detected by ATLAS.
Experiment SLC5
Migration Status - CMS is prioritizing on the 64 bit version first.
LHCb is running SLC5 native code on the nightly builds. ATLAS is also
currently integrating on the nightly builds. ALICE already migrated.
5 March 2009 - Minutes
ROOT 5.23/002
Released - The ROOT development release 5.23/02 was announced. ALICE is
already running on it in production. LHCb and ATLAS are currently testing
directly the head revision. A new ROOT web page based on the Drupal content
management system is in place.
Move to SL5 -
Additional SLC5 issues such as the cron/cvs patch, the Oracle client fix,
CERNLIB problem were discussed.
ATLAS Move to Geant4
9.2 - ATLAS decided to upgrade the simulation to Geant4 9.2. The
production releases for ATLAS and CMS have been delayed for 2 and 4 weeks
respectively.
19 February 2009 - Minutes
Migration to SL5
- Reviewed the list of pending issues related to the migration to SLC5.
The migration of the majority of the CERN resources to SLC5 at the
time scale of April is probably fine. The lxplus alias could be changed
sometime between April and September (before the experiments startup).
Every experiment is interested on a transition to SLC5/64bit of the Grid
resources as soon and as short as possible.
LCG_56 Released -
LCG_56 configuration was released last Friday. ATLAS has already taken it
and there are no problems so far.
