There is a GPU-over-network software called Juice [1]. I've used it on AWS for running CPU-intensive workloads that also happen to need some GPU without needing to use a huge GPU instance. I was able to use a small GPU instance, which had just 4 CPU cores, and stream its GPU to one with 128 CPU cores.

I found Juice to work decently for graphical applications too (e.g., games, CAD software). Latency was about what you'd expect for video encode + decode + network: 5-20ms on a LAN if I recall correctly.
