Advances in parallelization of cosmic rays simulations in CORSIKA 8 — •Antonio Augusto Alves Junior, Pranav Sampathkumar, and Ralf Ulrich for the CORSIKA 8 collaboration — Institute for Astroparticle Physics (IAP) - KIT

Advances in the parallelization of CORSIKA 8, which is being developed in modern C++17 and is designed to run on multi-thread modern processors and accelerators, are discussed.

Aspects such as out-of-the-order calculations, generation of high quality random numbers and fast task scheduling and submission on massively parallel platforms are highlighted, followed by presentation of preliminary performance measurements.

Finally, the design choices and integration into CORSIKA 8 are presented, together with some basic examples.
