Hi all,

First of all I appreciate all of the work that has been and is being put into making GPU programming possible in Julia. 🙂

I am new to GPU programming, and I basically just installed CUDA.jl and tried running ‘]test CUDA’ and I get the error below. Am I doing something wrong? The reason I write is that I got this same error on two machines, but I thought the first machine was broken. But now I got the same error on my brand new desktop computer, so I think this might be an error within the package?

I am on Windows 11. My previous machine which I thought was broken was running the Pop!\_OS Linux distro, but gave the same error. My system setup:

```julia
     Testing Running tests...

```

The error message:

```julia
Error in testset base/aqua:
Test Failed at C:\Users\...\.julia\packages\CUDA\htRwP\test\base\aqua.jl:12
  Expression: length(ambs) ≤ 15

ERROR: LoadError: Test run finished with errors
in expression starting at C:\Users\...\.julia\packages\CUDA\htRwP\test\runtests.jl:465
ERROR: Package CUDA errored during testing

```

Apart from the error I also see this warning:

```julia
gpuarrays/reductions/== isequal (5) | 24.84 | 0.01 | 0.0 | 1.07 | N/A | 0.69 | 2.8 | 3932.04 | 2085.66 |

      From worker 5: └ @ Main C:\Users\...\.julia\packages\CUDA\htRwP\test\base\aqua.jl:11

```

And this:

```julia

```

Aqua tests can be ignored and have been removed on CUDA.jl#master

Thank you for the clarification!
