Switch to the Julia Buildkite queue.

Maybe it's as simple as that.

Test failures are probably because we're now being given more than 1 thread? I think it would be best to limit to 1 thread for right now, until Distributed is more thread-safe.

[maleadt]

The tests still specify JULIA_NUM_THREADS: 1...

[maleadt]

Oh, maybe Sandbox.jl doesn't forward the JULIA_NUM_THREADS variable; with manual usage of the package you needed to set the env var. @staticfloat can you confirm?

Let's try setting the thread limit differently.

[jpsamaroo]

Looks like that's working!

[maleadt]

Are those failures expected? I'll let you merge if they are.

[jpsamaroo]

Yeah, they're probably fine. The BK script runs two separate test invocations (idk why), and often the latter run fails. I'll look into disabling the second run.

[jpsamaroo]

Thanks!

Hmmm. All environment variables should, by default, transfer in. There's really nothing special happening with regards to environment variables.

I ran a quick test here: https://github.com/JuliaComputing/BuildkiteTesting/pull/12 and you can see how the environment variable shows up in the build logs.

Strage; thanks for having a look though.
