Hello,  
I’m having some platform dependent problems getting CUDAnative working all the way. On my Ubuntu system I am having no problems, but on my windows machines the tests for the package are failing and I cannot make heads or tails out of it. I am seeing the same errors on 2 different systems with different GPUs, but both with Windows 10. I am including the mess that comes out of testing CUDAnative in the package manager.

Any ideas as to what the problem is and how I can fix it? I would really like to get this working on Windows.

Apologies for the newbie post.

Ah, I know what’s wrong. Another case of using the wrong formatting specifiers. Shouldn’t impact functionality though, so there’s nothing wrong with CUDAnative per se.

The ERROR\_NOT\_SUPPORTED is because apparently our tests try to use cooperative groups when they aren’t supported. Again, nothing wrong with CUDAnative, the tests should be fixed.

Thanks for clearing that up. I’m also having trouble with errors and CuArrays. When I test CuArrays, it returns numerous errors, but all tests pass. Then when I load the package I get a bunch of errors. Are these errors similar to the CUDAnative test erros, or do I have a build problem?

Again, sorry for the uninspiring questions, but I’d really like to know that the packages are all working properly before I start implementing things.

Those are Julia errors, and only occur on Julia 1.0. If you upgrade to, say, 1.1, those errors will be gone.

After upgrading to Julia 1.1, I am getting no errors. The reason I was using Julia 1.0.4 in the first place was that the readme on github for CuArrays says that it works out of the box with Julia 1.0 and I assumed that it might not be ready for Julia 1.1. It may be a good idea to clear that up in the readme so that other people like me don’t fall into the same confusion.

Thank you so much for your help!

Good suggestion, I’ve clarified the README.
