I'm curious if there are any GPU rental services, VM-based or otherwise, which you can rent for short periods of time and just do whatever you want with? Where you can pay for a few hours up-front, and then SSH into the box to run some mining scripts or test out new GPU code. Most everything I've found is for month long contracts, and I'm really just interested in something convenient where I can rent time on demand.
Does such a service exist, at roughly the associated mining cost? i.e. I'd pay roughly how much that same machine would earn mining on its own.
