Grid Computing at DESY DESY

[Home] [Mon/Admin] [Grid@DESY] [Certs & VOs] [VOMS] [CVMFS] [User Guide] [Install Guide] [Notes] [Talks & Posters] [Glossary] [Documentation] [Links]

In order to ensure response in case of problems, use the Global Grid User Support (GGUS) and/or your VO support rather than private e-mail contacts or internal mailing lists.


For the usage of the AFS UI, the production version, more recent version for testing, and the retirement of glite-3.1 please refer to Grid User Guides at DESY.


Since August 2004 DESY operates a Grid Centre in the context of the National Grid Initiative NGI-DE of EGI and the project Physics at the Terascale.

Within the Worldwide LHC Computing Grid (WLCG) DESY is a Tier-2 centre for ATLAS, CMS, and LHCb.

DESY supports the photon science community on the Grid.

DESY supports the EGI VOs 'biomed' and 'enmr.eu'.

The International Linear Collider Community (ILC) and the CALICE collaboration use the DESY Grid infrastructure for Monte Carlo production in cooperation with other Grid sites world-wide. ILC/CALICE users please also refer to Grid for ILC.

DESY joined the BELLE and BELLE II collaboration and supports the VO 'belle'. Please refer to Grid for BELLE and BELLE II.

Information about VOs can be found on the EGI Operation portal.

In Germany, user certificates are issued by GridKa of FZ Karlsruhe (FZK). DESY acts as a Registration Authority (RA) for GridKa and provides a registration service. In order to request a Grid certificate go to this web page, read the documentation thoroughly, and follow the steps as explained.

For the HERA experiments H1, HERMES, and ZEUS, and for the ILC Community, VOs 'calice', 'hermes', 'hone', 'ilc', and 'zeus' are officially supported by WLCG. In addition, more VOs are hosted by DESY, among them are 'ildg' for the Lattice QCD community LatFor, 'icecube' for the astro-particle physics community, 'olympus' for the OLYMPUS collaboration, 'xfel.eu' for XFEL.

The global entry point for User support in the Grid is the Global Grid User Support (GGUS).

New DESY users who need a Grid User Certificate may want to refer to Grid Certificates and VO Membership at DESY. Please also check the page on Frequently Asked Questions FAQ.

Sites which want to support the DESY VOs find the necessary configurations in VOMS at DESY and Installing DESY VOs on GLITE. See also the EGI's Operations Portal CIC for infos on the VOs.

An incomplete sample of examples and hints can be found in the Grid User Guides at DESY. There are also mailing list available.

DESY inFORM - Tiny Particles Demanding a Great Deal (Dec 2006)

The Grid in a flash

The Grid - explain it in 60 seconds

by Ian Foster, Argonne National Laboratory and the University of Chicago, published in the joint Fermilab/SLAC's magazine symmetry.

Having bought a new toaster, we simply plug it in: the electric power grid removes the need to also buy and install a new generator. By analogy, information technologists refer to the Grid when talking about on-demand computing.
Like its electrical namesake, a computing grid is a mix of technology, infrastructure, and standards. The technology is software that allows resource providers (whether individuals or institutions) to contribute computers, storage, data, networks, and other resources; it allows consumers to use them when needed. The infrastructure comprises the physical hardware and services that must be maintained and operated for the resource-sharing to occur. Finally, standards codify the messages that must be exchanged, and the policies that must be followed, to allow a grid to function.
The Internet, Web, and Grid are related but distinct technologies. The Internet is the worldwide system of networks that connects many computers and smaller networks, allowing them all to communicate. The Web is a way of accessing information over the Internet. The Grid is a way of using the Internet to share and manage computing resources that are distributed around the globe.
