VISITORS' PORTABLES: NETWORK ACCESS

Registration of Computers is mandatory at CERN: register your portable computer.

  1. Visitors WITHOUT a CERN Computing Account:
  2. Visitors or CERN users WITH a CERN NICE/mail account:
    • Register here (Attention: CERN Intranet page - register when at CERN)

Workshop Overview

This workshop will cover:

For each LHC experiment, detailed plans / requirements / timescales for 2007 activities.

Exactly what (technical detail) is required where (sites by name), by which date, coordination & follow-up, responsibles, contacts, etc etc

There will also be an initial session covering the status of the various software / middleware and outlook.

Most sessions will take place in the CERN main auditorium.

160 1-009 has been reserved from 16:00 - 18:00 on Monday, Tuesday, Thursday and Friday for potential BOFs, with the IT amphitheatre also available in this time slot, Wednesday included.

Please note that the experiment visit on Thursday afternoon is for a maximum of 50 people. Register early!
Please note that, due to the limited number of places, priority will be given to people from outside CERN.

A WLCG Collaboration Board (closed) meeting is foreseen for the afternoon of Thursday January 25 2007

A VOM(R)S workshop runs in parallel the full week

A dCache workshop will be held at DESY in the week prior to the WLCG Collaboration workshop.

Possible BOFs (see wikipedia entry under "Birds of a Feather")

  • Sharing tips & tricks between sites
  • h/w choices (farm nodes, storage - disk, tape & media etc.)
  • Monitoring in its various guises: service monitoring, site monitoring, Grid monitoring, experiment dashboards...
  • Remote management of Tier 2s
  • Site management tools (best practices, security, ...)
  • WAN routing problems and how to debug them
  • GGUS feedback and issues
  • ...
(Not an exhaustive list...)

      Discussion on vomrs/voms-admin development requirements and
      their impact on voms core and other voms-aware applications.
      VO managers, EGEE TCG, LCG and OSG management are invited to
      this BOF.

      To join the call, do one of the following:

      • Dial +41227676000 (Main) and enter access code 0164056, or
      • To have the system call you, click here: https://audioconf.cern.ch/call/0164056

      (Leader code is 0154083)

      Having all vom(r)s customers present will be the condition to better understand, agree and coordinate the requirements' implementation, release and deployment.

      BOF Outcome Summary as presented at the February 2007 by J.Shiers:

      A success in terms of:
 - Participation:
Several VOs: LHC Experiments,AUGER,VOCE and other
authorites: TCG,JSPG,NDGF
 - Communication between voms/vomrs developers in view of
any new feature proposals or changes in api.
 - Outcome:
Generic Attributes (GAs) are needed for ATLAS and LHCb.
VO managers must provide written requirements in
http://littleblue.cnaf.infn.it/twiki/bin/view/VOMS/VomsVomrsRequirements
Deadline for submitting requirements is MID FEBRUARY 2007.
GAs should be handled at the level of VO-specific software
and     will NOT be interpreted by the grid middleware.
