CROWN - A Software framework for fast analysis ntuple production — •Sebastian Brommer¹, Markus Klute¹, Nikita Shadskiy¹, Guenter Quast¹, Roger Wolf¹, and Sebastian Wozniewski² — ¹Karlsruhe Institute of Technology — ²Universität Göttingen

With the ever-increasing data recorded by the LHC experiments, new software solutions are required to handle the rising demand in computational power and to ensure fast and efficient processing of the data. The CROWN framework is designed to provide such a fast and robust solution for the conversion of stuctured event data into flat ntuples for histogramming and further analysis. Within the framework, code generation is used to create compiled C++ executables based on ROOT data frames, ensuring fast data processing with minimal dependencies.

In this talk, the core concepts of the framework as well as performance comparisons to existing solutions are presented.
