That's also something I thought about a few times already: drawterm with=20 GPU support. The only issue I see is, for realtime applications like=20 games the draw times would be network bound and thus pretty slow. It=20 would work for heavy GPU applications where almost no draw calls will=20 exist (no textures, very low poly meshes, ...), but for heavier stuff=20 we'd need to address that. That's the benefit of a native driver: you could calculate the server=20 side (heavy CPU calculations) on a cpu server, the client/frontend side=20 (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=20 compilation on my work PC (two GTX 1080Ti) and try figuring out how to do=20 all that stuff. However, I've never done graphics applications on windows=20 or somewhere else that uses OpenGL or DirectX (I'd try OpenGL because=20 portability), only written shaders so far. I'll surely need some time=20 (which is always rare as a game developer). Btw I don't know the exact specifications for GPU usage for neural=20 networks. I assume it's all compute shaders? Maybe it's even a kinda=20 blackbox, put stuff in (draw call), read things out. I assume this can=20 work perfectly fine for draw times, depending on the data. sirjofri ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/T65ec64adb5137874-Mf41fb= d4cbe7a7366feb7901a Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
