Distributed analysis system

The ATLAS strategy follows a service oriented approach to provide Distributed Analysis capabilities to its users. Based on initial experiences with an Analysis service, the ATLAS production system has evolved to support analysis jobs. As the ATLAS production system is based on several Grid flavours (LCG, OSG and Nordugrid), analysis jobs will be supported by specific executors on the different infrastructures (Lexor, CondorG, Panda and Dulcinea).

While submitting jobs to the overall system will provide seamless access to all ATLAS resources, we also support user analysis by submitting directly to the separate Grid infrastructures (Panda at OSG, direct submission to LCG and Nordugrid.)

A common job definition system is currently under development, which will be supported by all systems.

Finally a common user interface project, GANGA, will provide support for the various submission options and will provide a consistent user experience.
