Can anyone help me with the error above?

Sounds like the hardware isn't supported yet?

Thanks in advance

@VarLad Didn't you get rusticl successfully working at some point?

@maleadt Hey! I tested with llvmpipe (CPU backend of Rusticl).
For it to work on Rusticl drivers on AMD, we need either https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/35175 or #311 to be merged. I'm working on the latter.

@rrevi for your information, simply using latest git commit of mesa will now work with OpenCL.jl. Its not in a released version of Mesa yet though, but there are many ways to get mesa-git depending on your distro. :)

Working through this https://cuda.juliagpu.org/stable/tutorials/introduction/

Here is running (basic) computations on the CPU:

...and here is running the same computations on the GPU (instead):
