Dashboard Task Monitor for Managing ATLAS User Analysis on the Grid
This provides a practical solution for ATLAS analysis users to manage their Grid-based tasks more efficiently, though it appears incremental as it builds on existing dashboard infrastructure.
The paper tackles the challenge of managing distributed user analysis tasks on the Worldwide LHC Computing Grid for ATLAS at the Large Hadron Collider by introducing the ATLAS Dashboard Task Monitor, a web-based tool that enables monitoring and management (e.g., kill, resubmit) of tasks and jobs independently of the operating system and Grid environment.
The organization of the distributed user analysis on the Worldwide LHC Computing Grid (WLCG) infrastructure is one of the most challenging tasks among the computing activities at the Large Hadron Collider. The Experiment Dashboard offers a solution that not only monitors but also manages (kill, resubmit) user tasks and jobs via a web interface. The ATLAS Dashboard Task Monitor provides analysis users with a tool that is independent of the operating system and Grid environment. This contribution describes the functionality of the application and its implementation details, in particular authentication, authorization and audit of the management operations.
