Doesn’t most fraud happen with CPU’s? Spam, piracy, etc?
What’s behind this? A shortage doesn’t make sense because a first come first serve model works well. Is Nvidia pulling the strings?
Assume you rent a GPU to do PoW mining, using a stolen credit card, they can't charge you, but you have your coins and can disappear
The fraud thing has been a factor, for sure. You need some guarantees that your client is legit before you spend money on them.
Running big clusters of GPUs is a more challenging technical exercise than ordinary Hypervisors/VMs/K8s/whatever. Doubly so if you are doing multi-tenancy and containerization. It takes a lot of effort to rig that stuff up properly and integrate it with the rest of you management stack, and folks tend to be protective of it once it’s fired up.
