The Ramses community and the astro community at large are facing new challenges concerning large scale simulations and new computer architectures emerging in HPC clusers such as GPUs. Dyablo is a new Adaptive Mesh Refinement simulation code aimed at the Ramses community to perform hydro simulations with particles and self-gravity on multiple hardware achitectures. The code takes a more modern approach by using C++ and the Kokkos library to allow support for various current and future hardware architectures, such as GPUs, ARM processors or more conventionnal CPUs. In this talk i will present the current state of developpement of Dyablo and will explain the challenges that have already been overcome for AMR on GPU. Dyablo is still in a prototye phase, but promising performance benchmarks demonstrate that efficent AMR on GPU is possible.
