Description
DIRAC is a framework for building general purpose distributed computing systems. It was developed originally for the LHCb HEP experiment at CERN and now it is used in several other HEP and astrophysics experiments as well as for user communities in other scientific domains.
There is a large interest from smaller user communities to have a simple to use tool for accessing grid and other types of distributed computing resources like DIRAC. However, small experiments can not afford to install and maintain dedicated community services.
Therefore, several grid infrastructure projects are providing DIRAC services for their respective user communities. The DIRAC services are used for the user tutorials as well as to help porting the applications to the grid for a practical day-to-day work. The services are giving access typically to several grid infrastructures as well as to standalone computing clusters accessible by the target user communities.
In the paper we will present the experience of running DIRAC services provided by the France-Grilles NGI and other national grid infrastructure projects. Specific features needed to support multiple user communities by a single instance of the DIRAC service will be discussed. The outlook for provisioning of the new types of computing resources, like clouds or desktop grids, will be given.
