JuliaGPU CI moving to Buildkite

Hi all,

Because of GitLab limitations (no CI for external PRs, needs a repository mirror that can lose its sync, no real Julia support, only reuse of code through include, etc), Julia’s community GPU CI is moving to Buildkite. Instructions on how to set-up your repository are available at JuliaGPU/buildkite. For an example of a full-featured pipeline, have a look at the CUDA.jl pipeline.yml and its execution; very similar to the old GitLab pipeline, so migration shouldn’t be hard.

For now, I’ll be keeping a GitLab runner active, but with a very limited pool of runners. It’s thus recommended to switch your CI if you want fast jobs :slight_smile:
