Hi! I’m coming from this issue [**here**](https://github.com/JuliaGPU/CUDA.jl/issues/2522), which seems to not relate to CUDA.jl specifically.

Do you think it comes from my `openmpi`, `cuda` drivers installations ? Otherwise, could it come from MPI.jl ?

Well, seems it was a module issue from the cluster I work on and the test passes now. I’m closing the issue then.
