AMDGPU.jlProgramming AMD GPUs with Julia

Install ​

Simply add the AMDGPU.jl package to your Julia environment:

using Pkg
Pkg.add("AMDGPU")

Requirements ​

• Julia 1.10+:

• MI300X requires Julia 1.12+.

• 64-bit Linux or Windows.

• ROCm 6.0+.

Required software ​

Test ​

To ensure that everything works, you can run the test suite:

using AMDGPU
using Pkg
Pkg.test("AMDGPU")

Example ​

Element-wise addition via high-level interface & low-level kernel:

using AMDGPU

function vadd!(c, a, b)
   i = workitemIdx().x + (workgroupIdx().x - 1) * workgroupDim().x
   if i ≤ length(a)
       c[i] = a[i] + b[i]
   end
   return
end

a = AMDGPU.ones(Int, 1024)
b = AMDGPU.ones(Int, 1024)
c = AMDGPU.zeros(Int, 1024)

groupsize = 256
gridsize = cld(length(c), groupsize)
@roc groupsize=groupsize gridsize=gridsize vadd!(c, a, b)

@assert (a .+ b) ≈ c

Questions and Contributions ​

Usage questions can be posted on the Julia Discourse forum under the GPU domain and/or in the #gpu channel of the Julia Slack.

Contributions are very welcome, as are feature requests and suggestions. Please open an issue if you encounter any problems.
