    Scaling WaterLily.jl with MPI and an improved geometric multigrid solver

    Bernat Font, Marin Lauber, Tzu-Yao Huang, Gabriel D. Weymouth

    We present recent performance-oriented developments in WaterLily.jl, a scale-resolving incompressible flow solver written in pure Julia that runs seamlessly on CPUs and GPUs of any vendor. Supported by the newly added MPI-based parallelism, strong-scalability tests display a near-ideal linear trend, and weak-scaling efficiency is kept above 85\% before node memory-concurrency contention dominates parallel performance. Inter-node weak...
