Boards
The governance and coordination of the Worldwide LHC Computing Grid is supported by a number of boards and committees responsible for strategy, operations, technical coordination, and resource planning.
This page provides an overview of the principal WLCG boards, their responsibilities, membership, and meeting information.
See the WLCG Memorandum of Understanding Annex 5 “WLCG Collaboration” for further details on the Terms of Reference for each body.
The Collaboration Board (CB) provides the main technical direction for LCG.
The CB is composed of a representative of each Institution or federation of Institutions that is a member of the Collaboration, the LCG Project Leader and the Spokespersons of each LHC Experiment, with voting rights; and the CERN Chief Scientific Officer (CSO), and CERN/IT and CERN/PH Department Heads, as ex-officio members without voting rights, as well as a Scientific Secretary. The CB elects the Chairperson of the CB from among its Members.
The CB meets annually and at other times as required.

The MB supervises the work of the Project as a set of formal activities. It maintains the overall programme of work and all other planning data necessary to ensure the smooth execution of the work of the Project. It provides quarterly progress and status reports to the OB.
The MB endeavours to work by consensus but, if this is not achieved, the LCG Project Leader shall make decisions taking into account of the advice of the Board.
The MB membership includes the WLCG Leader and deputies, representatives of the Tier-0 and Tier-1 Centres, the Computing Coordinator of each Experiment, the Chair(s) of the Technical Coordination Board, the WLCG service and operation coordination manager(s), and a Scientific Secretary and other members as decided from time to time by the Board.

A standing committee of the Collaboration Board, the Overview Board (OB), has the role of overseeing the functioning of the WLCG Collaboration and of the WLCG MoU in particular.
The WLCG Overview Board also includes Tier-2 representatives to deal specifically with Tier-2 issues.
It also acts as a clearing-house for conflicts that may arise within the WLCG Collaboration. (WLCG MoU, 19 October 2005).

The WLCG Technical Coordination Board (TCB) is responsible for the technical evolution of WLCG services in line with the needs of the experiments and the capabilities of the infrastructure providers. The TCB defines a multi-year roadmap for such evolution and is responsible for its implementation. The TCB achieves these goals with a bottom up approach through an Open Technical Forum (OTF) which welcomes the participation of all contributors to the technical evolution in the WLCG community. The TCB may establish ad hoc technical working groups and projects as deemed necessary to accomplish its responsibilities.

The Resources Review Board (RRB) comprises the representatives of each Experiment’s Funding Agencies and the managements of CERN and of each Experiment’s Collaboration. It is chaired by the CERN Director for Research and Computing.

The purpose of the C-RSG is to inform the decisions of the Computing Resources Review Board (C-RRB) for the LHC experiments.
According to the WLCG, MoU the starting point of the scrutiny is the request information presented at the spring C-RRB meeting and any guidance that the C-RRB cares to give. From that moment the CRSG enters into a sustained dialogue with each experiment seeking to understand to what extent the computing resource requests are well motivated. The recommendations are presented in the RRB autumn meeting.
Every year the CRSG should scrutinize
- The resource accounting figures for the preceding year
- The use the experiments made of these resources
- The overall request for resources for every experiment for the following year and forecasts for the subsequent two years
- The CRSG shall also examine the match between the refereed requests and the pledges from the Institutions.
- The CRSG shall make recommendations concerning apparent under-funding This is the first time that such an independent and detailed scrutiny of the computing yearly request is carried out.

The LHCC was set up after the March 1992 meeting in Evian-les-Bains, where Expressions of Interest were presented. Intensive interaction between the Committee and the Collaborations is required in order to converge on the detector designs, and to review the construction, installation and commissioning of the experiments. Like other experiment committees, the LHCC makes recommendations to the CERN Research Board.
The LHCC also reviews the World LHC Computing Grid (WLCG) Project. The latter makes available to the LHCC for review documents and reports from the project, including its Technical Design Report.
