Description
The LHC's Computing Grid (LCG) middleware interfaces at each site with local
computing resources provided by a batch system. However, currently only the
PBS/Torque, LSF and Condor resource management systems are supported out of the box
in the middleware distribution. Therefore many computing centers serving scientific
needs other than HEP, which in many cases use other batch systems like Sun's Grid
Engine (SGE), are not integrated into the Grid. Binding a site running on the SGE
batch system is possible thanks to The London e-Science Centre's Globus JobManager
and Information Reporter components. However when using AFS instead of plain NFS as
shared filesystem some other issues arise. In collaboration with the Max Planck
Institute for Physics (Munich), and as part of Forschungszentrum Karlsruhe's
involvement in the MAGIC Grid project, we set up an LCG interface to Munich's Sun
Grid Engine batch system. This SGE-based cluster is currently at a remote location
(Garching's Computing Center) and a secure jobsubmission is achieved relying upon the
usage of the AFS filesystem. This allows an established "non-grid" computing center
to offer its resources via the Grid without any changes in the running infrastructure.
