iLCDirac and CI: Automated testing for distributed computing

Detector optimization studies for future high-energy physics experiments require the simulation and reconstruction of many physics processes and detector geometries. As an efficient way of accessing the necessary computational and storage resources, DIRAC has been developed and extended by iLCDirac, which is specialized for the applications used in the context of linear collider detector studies. We give a short introduction of grid computing and the concept of “High-throughput computing” behind DIRAC before explaining the unique features of DIRAC and iLCDirac. With this preparation we explain how we leveraged continuous integration to ensure smooth day-to-day operations, and that changes to the underlying code base do not cause an interruption of the service.
