Hello,

This is my first posting, and I am new to Julia. I have to say I love Julia so far, once I got over my ‘scoping annoyances’. 😉  
So far I programmed a multithreaded prime-generating program on the CPU which was good fun (and superfast). Now I am trying to get into GPU programming (CUDA)

My question concerns the output of the “test CUDA” command.  
I am not sure how to format this nicely, but here is the output.  
The testingsuite is complaining about: testset core\initialization.

I run on a MSI laptop  
OS: win11 prof  
nvideacard: NVIDIA GeForce RTX 4080 Laptop GPU

Can anybody advise me on this topic?

PS: I tried to post the whole output, but it was too much for this forum. So I cut away most, end left only the summary.

These failures are not an issue. The `aqua` failures are only for developers, and the `initialization` tests should normally run first but that doesn’t happen here because a path separator issue (as evident by the KeyError preceding it). So everything seems to be working fine.

Also, please use triple backticks to denote output; your post is pretty hard to read.

Actually, I thought the path separator issue was fixed already. Which version of CUDA.jl were you testing?

This is an old version. You can see in the releases section that we’re at version 5.x already: [GitHub - JuliaGPU/CUDA.jl: CUDA programming in Julia.](https://github.com/JuliaGPU/CUDA.jl/)

If you’re not sure why an old version is being installed, try forcing installation of the latest version by doing `]add CUDA#5.2`. You can also always test the latest version in a clean environment by first doing `]activate --temp`.

So that is only that aqua left. No problem (since I am not a developer for CUDA)

Hey all, piggybacking on this thread.

I’m trying to test my installation of `CUDA.jl` but the process repeatedly get stuck. I get to this:

```

then whatever process is being tested takes hours and never completes. Any guess as to what might be causing that?

EDIT: I tried again and when the program is left hanging, I can’t even `ssh` to the computer where the test is taking place. In the end, I have to pull the plug on the machine.

Hi jrekier,

I googled and found this overview:

Look up your CPU ( NVIDIA GeForce GTX 960 ) and you’ll see that is it a bit old.  
You maximum CUDA seems to be until CUDA 10.

But you are using CUDA driver 12.5

Hey @ErwinMoller, thanks.

Hm, that might be why. Although I’ve been running some tests manually and it seems to be working okay, aside of the automated CUDA.jl test…
