Minutes of previous meeting(s) (September 16) and matters arising

The minutes of the last meeting were approved.

Fabric management progress & plans (Tim Smith)

Tim gave an overview of the current work in the area of fabrics automation. The tools used have been developed in the framework of the EDG workpackage 4.

His slides are available at:

A summary of the architecture is given in a CHEP03 paper:  http://arxiv.org/ftp/cs/papers/0305/0305050.pdf

 

The basic principle is that all nodes are autonomous where the complete process of software installation is automatized. A recent example for the benefit of the system for software maintenance was the upgrade from LSF version 4 to 5 which was done in 10 minutes compared to 3 weeks by 3 people for the previous upgrade.

LEMON – Monitoring the CERN computer centre (Helge Meinhard)

Helge summarized the status of the LEMON (Lhc Era MONitoring) project. The components MSA (Monitoring Sensor Agent), OraMon (Oracle based repository) and LEAF (LHC Era Advanced Fabrics) have been developed in the framework of the EDG/WP4 and are already in production at CERN.

The slides Helge presented are at:

Report from SC2, miniPOB, interactions with LHCC referees (Les Robertson)

Les forwarded to the PEB the SC2 report to the mPOB by Matthias. Les mentioned that the agreement with EGEE requires changing the operational management of LCG and presented a draft structure discussed in the SC2. It was felt that the computing coordinators of the experiments should be more involved in the day-to-day management of the project.

In the meeting with the LHCC referees Ian has presented the status of LCG-1. It is necessary to have the US and European versions of RLS communicate. The move to gcc 3.2 was completed.

 

Status of verification milestones (Jürgen Knobloch)

By the time Jürgen came to his presentation, only two experiment representatives were left. Jürgen briefly presented the verification milestones proposed by the experiments. It was agreed to try to come to a conclusion on verification milestones to be entered in the baseline at the next meeting.
