Many thanks,

I use exactly the same versions of the all packages with all julia versions (via the package manager and instantiate). The machine is the same. The only difference is if I use julia 1.7.1 or julia 1.6.5 (both downloaded from the julialang webpage). This should also guarantee that the same artifacts versions are used, right?

I am stuck in CUDA v3.3 because of a breaking change in later versions (see [Problem with CUDAv3 - #9 by shiroghost](https://discourse.julialang.org/t/problem-with-cudav3/71118/9)). In any case, it is worrying that exactly the same packages give different results in different julia versions (without random numbers involved).

I would probably have to chase this down the rabbit hole…
