deep learning is another interest of mine too. hardware support is a big deal for that... some kind of support for GPUs would be nice. people have discussed that for years... hardware drivers are difficult and important to do correctly! I always really liked the "XCPU" and drawterm type ideas of using other OSes for their existing strengths along with Plan 9. maybe drawterm could have a GPU device driver or something... that being said I have sometimes found it ends up surprisingly easier doing it all on Plan 9...
That's also something I thought about a few times already: drawterm with GPU support. The only issue I see is, for realtime applications like games the draw times would be network bound and thus pretty slow. It would work for heavy GPU applications where almost no draw calls will exist (no textures, very low poly meshes, ...), but for heavier stuff we'd need to address that.
That's the benefit of a native driver: you could calculate the server side (heavy CPU calculations) on a cpu server, the client/frontend side (including draw calls) on a terminal and the pure graphics on the GPU.
I'd still give the drawterm GPU a shot. Maybe I can set drawterm up for compilation on my work PC (two GTX 1080Ti) and try figuring out how to do all that stuff. However, I've never done graphics applications on windows or somewhere else that uses OpenGL or DirectX (I'd try OpenGL because portability), only written shaders so far. I'll surely need some time (which is always rare as a game developer).
Btw I don't know the exact specifications for GPU usage for neural networks. I assume it's all compute shaders? Maybe it's even a kinda blackbox, put stuff in (draw call), read things out. I assume this can work perfectly fine for draw times, depending on the data.
