Description
In Germany, several university institutes and research centres take
part in the CMS experiment. Concerning the data analysis, a couple of
computing centres at different Tier levels, ranging from Tier 1 to
Tier 3, exists at these places. The German Tier 1 centre GridKa at the
research centre at Karlsruhe serves all four LHC experiments as
well as for four non-LHC experiments. With respect to the CMS
experiment, GridKa is mainly involved in central tasks.
The Tier 2 centre in Germany consists of two sites, one at the
research centre DESY at Hamburg and one at RWTH Aachen University,
forming a federated Tier 2 centre. Both parts cover different
aspects of a Tier 2 centre. The German Tier 3 centres are
located at the research centre DESY at Hamburg, at RWTH Aachen
University, and at the University of Karlsruhe. Furthermore a German
user analysis facility is planned to be built.
Since the CMS community in German is rather small, a good cooperation
between the different sites is essential. This cooperation includes
physical topics as well as technical and operational issues. All
available communication channels such as email, phone, monthly video
conferences, and regular personal meetings are used. For example, the
distribution of data sets is coordinated globally within Germany. Also
the CMS-specific services such as the data transfer tool PhEDEx or the
Monte Carlo production are operated by people from different sites in
order to spread the knowledge widely and increase the redundancy in
terms of operators.
