Distributed Parallelization of xPU Stencil Computations in Julia | S. Omlin, L. Räss | JuliaCon 2022

We present a straightforward approach for distributed parallelization of stencil-based Julia applications on a regular staggered grid using GPUs and CPUs. The approach allows to leverage remote direct memory access and was shown to enable close to ideal weak scaling of real-world applications on thousands of GPUs. The communication performed can be easily hidden behind computation.
