Chris Hill is a principal researcher at MIT. He is a lead architect of the widely used MIT General Circulation Model (MITgcm). He has been working with the Julia community for almost a decade.
This talk will present scaling and performance of the Oceananigans.jl ocean model on CPU and GPU systems. Oceananigans.jl is an all Julia code that is designed to study geophysical fluids problems ranging from idealized turbulence to planetary scale circulation. It uses the KernelAbstractions.jl package to support CPU and GPU single address space parallelism. It uses MPI.jl, to support multi-node and multi-GPU parallelism. MPI.jl is used both directly and through PencilArrays.jl.
