Julian P Samaroo

I am an HPC software engineer working at the JuliaLab. I maintain Dagger.jl, AMDGPU.jl, and BPFnative.jl, and generally enjoy the challenge of hacking on compilers and HPC runtimes.

BPFnative.jl: eBPF programming in Julia
Julian P Samaroo

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.

GPU programming in Julia
Valentin Churavy, Tim Besard, Julian P Samaroo

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.

GPU programming in Julia BoF
Valentin Churavy, Tim Besard, Julian P Samaroo

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!

Easy, Featureful Parallelism with Dagger.jl
Julian P Samaroo

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!
