Grid Deployment Board

The Grid Deployment Board GDB is part of the LHC Computing Grid Project (LCG) and represents in particular the resource centres.

The GDB has several roles, including:

• to make agreements between the resource centres and the experiments (VOs) - in practice this will require background agreements with other organisations that run various parts of the infrastructure - such as grid operations, certificate authorities, organisations providing VO management, network providers, etc.;

• to make agreements between resource centres;

• to make agreements between resource centres and CERN;

• to review schedules, service performance, resource utilisation, etc.;

• to exchange information.

Members of the GDB  <GDB membership list>  are representatives from each country that participates in LHC computing, representatives of the experiments and CERN and officers of the LCG project.

As for voting, each country has one vote. For a vote during a meeting only people present may vote. Votes may be delegated from the official country delegate to other people if announced to the GDB chairperson prior to the meeting.

The GDB chairman is elected for a two-year period (election rules). Re-election is possible but only with a 2/3 majority. Candidates, who do not have to be members of the GDB, are proposed by members at least one month in advance of the meeting at which the election is to be held.

The GDB reports to the LCG project leader. The chair of the GDB is an ex officio member of the Project Execution Board, in which he represents the interests of the resource centres.

The GDB meets every month. Normally those meetings are held at CERN and exceptionally in other places. Meetings are now held during two consecutive days, the first day for more technical issues, the second day more managerial.

The GDB may start and stop working groups when needed. Currently three working groups are operational on:

• security policies. <JSPG web site>  The Joint Security Policy Group JSPG is a joint group with the EGEE project and the Open Science Grid collaboration. The chair person is Dave Kelsey from RAL.

• networking. <OPN web site> The Optical Private Network OPN group is concerned with all networking for the LHC data distribution and analysis but currently concentrates on the Tier-0 to Tier-1 network. The chairperson of this group is David Foster from CERN.

• software installation tools. <Quattor web site> This group works on tools for the automatic installation and configuration of the LCG software. The mandate of this group <mandate of the Quattor group> has carefully been described when it started. The chairperson in Charles Loomis from LAL in Orsay.

 A fourth activity, coordinating and monitoring the Service Challenges <Service Challenges wiki> , has been started by the GDB. This is organised as a separate activity with meetings open to all those involved in the Service Challenges, overseen directly by the GDB.
