Description
Dyablo is a new high-performance hydrodynamical code designed for large-scale astrophysical simulations, from solar system dynamics to galaxy formation and cosmic reionization. Unlike many existing codes, Dyablo has been designed from scratch to run entirely on the available hardware, whether NVIDIA and AMD GPUs or CPUs accelerated with OpenMP. This architecture enables significant potential speedups compared to traditional CPU-based approaches and even hybrid codes that offload heavy computations to GPUs. Early benchmarking on idealized test cases demonstrates superior performance over RAMSES and strong scaling up to thousands of GPUs or tens of thousands of CPUs, highlighting Dyablo’s potential for next-generation astrophysical modeling. At the conference, we will present the first scientific applications of Dyablo, showcasing its capabilities and future prospects.
