PANDA is one of the main experiments at the new FAIR facility and will investigate the properties of hadrons in the charm quark mass region produced in antiproton annihilation reactions. The PANDA experiment will produce a large amount of data (1 PB/year) and the analysis will require the continuous use of several hundred CPUs. To accomplish this Grid Computing (distributed analysis/storage of data) is needed.
AliEn based PandaGrid, though, provides the physicist not only with computing resources but with a complete suite of tools and services, freeing the user from the overhead of software installation, configuration, data storage, and job management.
The functionality has been tested in three large data challenges. Currently the most room for optimisation lies in improving distributed data storage and data access. Therefore various parameters for optimising xrootd based Storage Elements have been investigated and the effects on inter site transfer as well as local data access is being studied.
