Centralized PanDA Blacklisting System — •Arwa Bannoura — Bergische Universität Wuppertal

PanDA is the distributed production and distributed analysis system for ATLAS. A concurrent update on the status of PanDA queues causes inconsistencies. This information can be updated by shifters and different agents like Hammercloud (a distributed analysis testing system). A centralized PanDA blacklisting system was implemented within AGIS (ATLAS GRID Information System) to manage the information about the status and update PanDA with the final status. The decision of the final status is based on the priority of the agent/shifter and how restricted is the proposed status. The system includes a RESTful API as well as a WebUI to manage and view the blacklisting status information of queues and clouds.
