Abstract
To allow non-LHC communities access to the primarily LHC dominated resources of the grid, the GridPP consortium in the UK maintains a multi-VO DIRAC service for this user-base.After an extensive testing phase, this service has been in production for the last two years and has been fully integrated into the user communities’ workflows. We report on the approaches taken by the VOs and the insights gained from these.
Highlights
GridPP [1] is a collaboration of physicists and computer scientists from leading UK universities, Rutherford Appleton Laboratory (RAL) and CERN
Observations and Conclusions DIRAC was conceived as a single VO framework and not all features are truly multi-VO, such as the listing of available sites and enabling sites on a VO-by-VO basis
Users have remarked on the particular unhelpfulness of error messages, this is not necessarily due to the DIRAC middleware but rather the error support in the underlying tools and is probably beyond the scope of this project to fix
