CERN Accelerating science

New MoU Preparation

If you wish to register a new Federation, then your institute/national funding agency will be required to sign a Memorandum of Understanding with WLCG, to set up the framework of agreements regarding resources and services you will provide.

Here is an example of a full MoU, which gives you the basic legal framework.

Please also look at Annex 3 (Minimal Computing Resource and Service levels to qualify for WLCG membership)  which explains the services you would be expected to provide.

If you have not already done so, you should contact whichever LHC experiment(s) you wish to support to discuss their resource requirements and your contribution. if you need contact names to do this please contact

As soon as the MoU is signed by both yourselves and CERN/WLCG, your site(s) will be added to the WLCG monitoring tools, accounting and reliability/availability reports.

Preparation of the MoU

For us to prepare the draft for you to review, we require the following information. Examples of information contained in the Annexes can be found in the Memorandum of Understanding overview.

  • information for the signature page – the name(s), and title of the signatory or signatories
