CORSIKA is a long-established software for simulations of atmospheric showers induced by cosmic rays. It has been developed mainly in Fortran 77 continuously for the last thirty years. It is very difficult to add new physics functions to CORSIKA7. CORSIKA8 is a modern rewrite in C++17 with a modular structure that improves flexibility and extensibility. It uses modern concepts in object-oriented programming. The CORSIKA8 project aims to achieve high performance by using techniques such as vectorization, gpu/cpu parallelization, extended use of static polymorphism and to have the most accurate physical models available. We plan to compare the results, especially fluences, energy distributions and transport in media (water, air, rock, ...) between these software concepts and to compare them with data from the KM3NeT experiment in particular. The results can be used to calibrate detection systems and analyze experimental data from the KM3NeT experiment detectors, but in principle also from others.
