Hello,

While I’ve been using Julia for a number of years now, this is my first attempt to use CUDA with Julia. I’ve encountered some errors while running the tests.

As in the Julia CUDA manual, " On Windows, also make sure you have the Visual C++ redistributable installed." I downloaded the Visual C++ redistributable [2015 - 2019] and tried to install it.

It turns out that there is a more recent version [2015 - 2022] already installed on my system

MS VS C++ redistributable

which prevents the linked redistributable from being installed.
Is having the more recent redistributable installed okay?

Advice on how to address these errors would be appreciated.

Yes, that should be fine. If you don’t have it installed, you’ll run into The specified module could not be found errors during testing.

The base/examples test failures are probably unrelated. Try running each example in isolation (from the examples/ folder in the repository) to see which one fails.

Thanks for your reply and advice.

In the directory
C:\Users\. . .\.julia\packages\CUDA\oymHm\examples

I found the following

julia> include("pairwise.jl")

As all the tests worked, is this the correct examples/ directory to run the tests?
