Description
The Cherenkov Telescope Array Observatory (CTAO) is the next generation ground-based observatory for gamma-ray astronomy at very high energies. It will consist of tens of Cherenkov telescopes, spread between two array sites: one in the Northern hemisphere in La Palma (Spain), and one in the Southern hemisphere in Paranal (Chile). Currently under construction, CTAO will start scientific operations in the next years for about 30 years. CTAO is expected to produce 2PB of raw data each year and to manage a global data volume which will grow through the years to reach around 100 PB. In addition, CTAO will require a high computing capacity for data processing and Monte Carlo simulations, of the order of hundreds of millions of CPU HS06 hours per year. To meet these requirements, CTAO will have a distributed computing model using 4 academic data centers, and use the DIRAC framework as its workload management system. In the past ten years, to optimize the instrument design and study its performances, CTAO has used the EGI grid infrastructure to run massive Monte Carlo campaigns. For these campaigns, CTAO has developed a production system prototype, based on DIRAC, to automatize the simulation and data processing workflows. This production system uses meta-data to link the different steps of a workflow. Recently, we have developed an interface to this system allowing for the configuration and submission of complex workflows.
In this contribution we present the CTAO production system and its use during the latest Monte Carlo campaigns as well as its recent interface development.
