AMD ROCm

The Julia programming support for AMD GPUs based on the ROCm platform aims to provide similar capabilities as the NVIDIA CUDA stack, with support for both low-level kernel programming as well as an array-oriented interface.

Julia support exists in the form of a single package:

• AMDGPU.jl

This package contains everything needed to access the HSA runtime, program GPU kernels, and utilize a user-friendly array-based interface. The stack originally was divided into 3 separate packages, which still exist and may be of use for interested users and developers:

• HSARuntime.jl: interfacing with the HSA runtime

• AMDGPUnative.jl: GPU kernel programming support

• ROCArrays.jl: array programming interface

At this point, the toolchain is a work in progress, although it is quite functional for simple usecases. We only officially support Julia 1.4 and Julia 1.5.
