Does charliecloud support the Intel GPU? If not，do you have plan to support the Intel GPU?
we want to use charliecloud running AI code on Intel GPU.
Thank you very much!

I'm not familiar with what specifically the Intel GPUs need, but if it's injecting stuff from the host like nVidia, ch-fromhost would be able to do that.

We would welcome a PR to add an e.g. --intel-gpu switch to ch-fromhost to package up the knowledge about what to do for Intel.
