apollon is a small rust utility to perform GPU-accelerated discrete event simulations
given an initial state, state change functions, and some definition of a time domain over which to iterate.

From theoi.com/Olympios -
APOLLON (Apollo) was the Olympian god of prophecy and oracles, music, song and poetry, archery, healing, plague and disease, and the protection of the young.
...[He slew] the serpent Python which guarded the oracular shrine of Delphoi (Delphi).
Discrete event simulators are often used as a type of prophecy or oracle allowing us to peer into the future given some initial state. I also find the myth about slaying the serpent Python a great prophecy in itself as Python is typically used for ad-hoc event simulators which this tool aims to replace with high-performance OpenCL primitives and connecting simulaton config files.
