The international research communities of Astroparticle and Particle Physics have a long history of tackling data-driven scientific questions using High Throughput Computing (HTC). Large scale usage of dedicated High Performance Computing (HPC) centers by these communities is a challenge for both scientists and computing centers. As such, the Simulation and Data Lifecycle Lab (SDL) Astroparticle and Particle Physics operates at the meeting point between HTC and HPC in order to enable and promote the technology and knowledge transfer between all involved communities.
