Description
The ATLAS production system provides access to resources across several grid flavors.
Based on the experiences from the last data challenge the system has evolved. While
key aspect of the old system are kept (Supervisor and executors), new implementations
of the components aim for a more stable and scalable operation. An important aspect
is also the integration with the new data management system, Don Quijote 2. A
graphical user interface supports the interaction of users with the system. The
system provides direct support for user analysis jobs, including user job definitions
and authenticated access based on globus proxy certificates. An initial version of
this system is currently under test on the LCG infrastructure and first user
experiences have been collected. Currently the turnaround time for user jobs is under
study. Special considerations are given to the operation of the system in parallel to
standard ATLAS production. An issue of concern is also the overall scalability of the
system. It is planned to provide it as service to all ATLAS user on a short time
schedule.
