Hi all, I’m running tests for CUDA.jl (`]test CUDA`) and I have one test failing. Should I be concerned, or can I safely ignore it?

```julia
Error in testset initialization:
Test Failed at /usr/local/pace-apps/manual/packages/julia/1.7.2/gcc-8.3.0/pace/packages/CUDA/Axzxe/test/initialization.jl:98
  Expression: CUDA.math_precision() != :Float16
   Evaluated: Float16 != Float16
ERROR: LoadError: Test run finished with errors
in expression starting at /usr/local/pace-apps/manual/packages/julia/1.7.2/gcc-8.3.0/pace/packages/CUDA/Axzxe/test/runtests.jl:550
ERROR: Package CUDA errored during testing

```

Here is the info about my system. Thanks!

Not a significant issue, but an issue nonetheless. Could you file it on the CUDA.jl repository?
