Description

@colleeneb

We are seeing a sefgault with some code on Aurora. Credit to @j-hayes . Let us know if more info is needed! It should be reproducible on Aurora.

Reproducer

Code

using oneAPI
using Base.Threads

function main()
    num_devices = 1
    p = 2
    W_matricies = Array{oneAPI.oneArray{Float64}}(undef, num_devices)
    println("starting"); flush(stdout)
    Threads.@threads for device_id in 1:num_devices
        oneAPI.device!(device_id)
        println("Current iteration: ", device_id)
        W_matricies[device_id] = oneAPI.zeros(Float64, p)
        println("done $device_id"); flush(stdout)
    end
    println("done"); flush(stdout)
end
main()

Run
