RDCSim: a GPU-Accelerated, Interactive Simulator for Reaction--Diffusion Chemistry

This paper presents RDCSim, an interactive simulator for reaction--diffusion chemistry (RDC) research, being developed as part of an ongoing project studying how humans interact with unconventional computing systems. While much research into the computational properties of RDC makes use of simulations, the development of multiple RDC simulations across different research groups can lead to results that are harder to reproduce. By automating the storage of parameter values alongside simulation results, RDCSim aims to make reproducing RDC results painless. This paper presents the functionality of RDCSim, and verifies the behaviour of the underlying chemical simulation using two seminal examples from the RDC literature: logical AND gates and chemical diodes.
