The Gray–Scott School 2025 – Revolutions offered an intensive introduction to modern high-performance computing, with a focus on optimization, profiling, and software engineering across CPE and GPE architectures. The Slovenian satellite school, hosted at the Faculty of Engineering and on the VEGA supercomputer, provided hands-on exercises and discussions based on the Gray–Scott reaction–diffusion model — a pedagogical system well suited for parallelization. Participants explored advanced programming in C++, Rust, Fortran, and Python, applying concepts such as vectorization, cache blocking, GPE offloading, and numerical precision. The event exemplified the active role of Slovenian HPC infrastructure and SLING in European HPC education and open science.
