GPU programming in Julia

07/20/2021, 2:00 PM โ€” 5:00 PM UTC

In this workshop, we will demonstrate three major packages for programming GPUs in Julia (CUDA.jl, AMDGPU.jl, oneAPI.jl), and the different programming models, tools and APIs that these packages support.

Enzyme.jl -- Reverse mode differentiation on LLVM IR for Julia

07/28/2021, 5:00 PM โ€” 5:30 PM UTC

Enzyme ( is a reverse mode auto-differentiation tool that performs automatic differentiation over LLVM intermediate representation and synthesis high-performance reverse-mode functions. We will discuss how Enzyme.jl integrates with the Julia compiler and special considerations required for differentiating a dynamic programming language such as Julia.

Scaling of Oceananigans.jl on multi GPU and CPU systems

07/29/2021, 1:00 PM โ€” 1:10 PM UTC

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.

Julia in High-Performance Computing

07/29/2021, 4:30 PM โ€” 5:15 PM UTC
BoF/Mini Track

The JuliaHPC community as a group maintains the infrastructure for using Julia in high-performance computing. In this BoF we invite newcomers, application developers, and maintainers to join us for an informal discussion around the state of Julia in HPC.
