Caching for Analysis Workloads of the ATLAS LHC experiment: Size-Aware Caching Policies

My 2022 CERN Summer Student project has been based on the study of cache management in large, geographically distributed systems used for scientific computation. In
particular, we considered as a use-case the Large Hadron Collider (LHC) located at CERN (the European Center of Nuclear Research), which is the world’s largest particle accelerator. This unique and complex facility allows scientists to study elementary particles and fundamental laws of physics while posing specific storage and computing challenges. To solve them, scientists and engineers have developed the Worldwide LHC Computing Grid (WLCG), which is a federation of large and small computing centers distributed around the globe (in total, around 170 sites located on 5 different continents).
