8 June 2009 Minutes

RAL Power Outage - A main outage of the RAL Tier1 (RAL-LCG2) will take place over a period of a couple of weeks at the end of June and early July. A detailed blog of the scheduled outages for component services is available. Link 

18 May 2009 Minutes

GLite 3.1 Update 46 Release – Update 46 includes DPM and LFC 1.7. DPM 1.7 includes changes needed for correct publishing of installed storage capacity at sites using this SE. Therefore all WLCG sites are strongly encouraged to upgrade as soon as possible. This update also included updates to the VOMS client. This was not originally intended, but RPM dependencies made it necessary.

GLite 3.2 Moving to Pre-Production - The gLite 3.2 UI (on 64 bit SL5) will be moving to the PPS this week.

11 May 2009 Minutes

Sites Should Test SCAS/glExec - Tier1s and bigger Tier2s are encouraged by the WLCG management board to deploy SCAS/glExec for testing in a production environment, to be done through the pilot installation the SCAS team. There is an interesting post on the GridPP blog concerning High Availability LFC. Link

4 May 2009 Minutes

CREAM CE for CMS - Request to sites supporting CMS to deploy CREAM CEs in production, or to enable CMS in the existing ones if this is not the case, to support the CMS CREAM pilot which has decided to focus activity in a new instance of WMS-ice deployed at CNAF pointing to production cream CEs.

CE Information - VO related info published by YAIM for CEs maybe incorrect, only for new installations (new CEs), read release notes for update 45 to gLite 3.1 sites without 64 bits capability have to stay with gLite 3.1 for now; no plans at the moment to deprecate gLite 3.1, depends on how long need to be supported before all hw at the sites moves to 64 bits.

27 April 2009 Minutes

Issues with 64 Bits WNs - Sites in the UK and in South East Europe highlighted the fact that they will rely on strictly 32 bit hardware for some time. As such the final demise of gLite 3.1 as being the last 32 bit release is very significant to them.

20 April 2009 Minutes

GLite Update 44 Released - gLite 3.1 update 44 with CREAM-CE released to Production and is especially useful for CMS and ALICE.

6 April 2009 Minutes

RSS Feed for Downtime Modifications - ATLAS requested for the RSS feed to be updated if a downtime is modified, and the modification itself logged. GLite releases are on schedule. There are now reference cards for gLite services.

Build Servers for Experiments – Discussion and clarification on how to improve the communication channels with IT Department for issues related to the IT build servers (lxbuild). 

Update on SL5 - Reviewed all additional pending issues for the SLC5 migration of the Applications Area software.

Workshop on Multi-core and Virtualization - Preparation of the Workshop on adapting applications and computing services to multi-core and virtualization.

16 April 2009 - Minutes

ATLAS Migration to SVN - Update of the ATLAS status and plans for the migration from the CVS code repository to the SVN one.

Agreed on LCGCMT_56a Contents - Discussed and agreed the contents for the proposed new configuration (LCGCMT_56a).

Issues with SLC5 Migration - Reviewed additional pending issues for the SLC5 migration and how to improve communication. Missing recent update on the concrete plans of deployment of it at CERN.

ATLAS 64 bits Apps Footprint - ATLAS reported a significant reduction of the virtual memory needs for 64 bit binaries such that they can run 64 bit applications on the Grid.

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.
