Description
The Future Circular Collider (FCC) aims to push the energy and intensity frontiers of particle colliders and plans to be the future of particle physics after CERN’s High Luminosity Large Hadron Collider (HL-LHC) reaches its conclusion in around 2040. To reach its full physics potential it will take multiple decades of operation and having a strong software and computing program. Supporting such an ambitious endeavor needs overcoming unique challenges and FCC-ee should take the opportunity to learn from previous experiments, such as the ATLAS experiment at the LHC. The ATLAS experiment has a complex Input/Output (I/O) software that allows efficient handling of the experiment’s most important asset, its data. Since the beginning of the LHC data-taking, ATLAS successfully analyzed hundreds of petabytes of data, a figure that is expected to reach multiple exabytes through the HL-LHC.
In this presentation, we will discuss ATLAS’ I/O and data storage software, focusing on experiment agnostic concepts such as:
- Handling of complex Event Data Model (EDM), including EDM evolutions,
- Supporting backward, and forward, compatibility,
- Supporting different storage technologies,
- Optimizing various performance aspects.
Most importantly, we will discuss how these can be helpful in designing and implementing I/O software for the FCC-ee experiments.
