vulkan suites and multiples maintainers

[Yuri Victorovich]

Olivier,


* Correction (use_vulkan should be ON of course):
# ollama
ollama_enable="YES"
ollama_user={your-user}
ollama_use_vulkan=1



I believe that Vulkan support is somewhat broken in ollama so that it 
sometimes acts up if models do not fit but smaller model like qwen2:1.5b 
only needs <2 GB and should fit into any device.
It should work meaning you should be able to chat with it, and the log 
at /var/ollama-{user}.log should show that most or all layers were 
offloaded to the GPU (grep for the work "offload").


Thanks,
Yuri
