Description
Computer clusters at universities are usually shared among many groups. As an
example, the Linux cluster at the "Institut fuer Experimentelle Kernphysik" (IEKP),
University of Karlsruhe, is shared between working groups of the high energy physics
experiments AMS, CDF and CMS, and has successfully been integrated into the SAM grid
of CDF and the LHC computing grid LCG for CMS while it still supports local users.
This shared usage of the cluster effects heterogeneous software environments, grid
middleware and access policies. Within the LCG, the IEKP site realises the concept of
a Tier-2/3 prototype center. The installation procedure and setup of the LCG
middleware has been modified according to the local conditions. With this dedicated
configuration, the IEKP site offers the full grid functionality such as data
transfers, CMS software installation and grid based physics analyses. The need for
prioritisation of certain user groups has been satisfied by supporting different
virtual organisations. The virtualisation of the LCG components, which can improve
the utilisation of resources and security aspects, will be implemented in the near
future.
