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.

This is a BoF to talk about the various GPU programming packages in Julia:

• CUDA.jl
• AMDGPU.jl
• oneAPI.jl
• KernelAbstractions.jl
• GPUArrays.jl
• GPUCompiler.jl
• ...

If you have any thoughts or questions about these packages, or other approaches to GPU programming in Julia, please join this BoF to chat about it!

Parallelizing codes with Distributed.jl is simple and can provide an appreciable speed-up; but for complicated problems or when scaling to large problem sizes, the APIs are somewhat lacking. Dagger.jl takes parallelism to the next level, with support for GPU execution, fault tolerance, and more. Dagger's scheduler exploits every bit of parallelism it can find, and uses all the resources you can give it. In this talk, I'll build an application with Dagger to highlight what Dagger can do for you!

eBPF is a virtual machine that can run user-defined code in the Linux kernel. The ability to generate eBPF bytecode from Julia would allow our Linux users to introspect, manipulate, and explore the core of their operating system from the comfort of a high-level language. In this talk, I will explain the basics of eBPF, how it's integrated and used in the Linux kernel, and how we can use "eBPF superpowers" from Julia.
