Introducing Constellation - Development of a flexible DAQ Infrastructure Framework — •Stephan Lachnit — DESY, Hamburg, Germany

Test beam qualifications of new detectors are very volatile environments which require stable operation and synchronization of multiple devices while allowing for fast integration of new prototypes. For this purpose, a centralized run control software is usually used to distribute commands and to manage data recording and logging.

Constellation is an upcoming open-source DAQ infrastructure framework with the goal to implement such a run control software. The main aspect is the orchestration of different data acquisition "satellites" with the run control and other satellites for data storage.

In this talk several design concepts of Constellation will be presented, including for the Final State Machine, Messaging via ZeroMQ, zero-configuration networking, dynamic loading of DAQ modules and support for EUDAQ2 modules.
