The JuliaCon is an annual conference dedicated to everything on Julia, including high performance computing.  This year it was conveniently located in Mainz. Vivienne Ehlert and Simon Candelaresi participated and presented their work using Julia. Vivienne gave a talk on "Reproducible Parallel Adaptive Multisolver Coupling of Trixi.jl and deal.II", while Simon presented a poster on "Massively parallel numerical simulations with Julia".
