Vast.ai - Using GPU and CPU at same time!
#1
When I am running hashcat on my computer, I can use my GPU and CPU the same time. The CPU looks like to add 10% to 15% more power.

But when I try it in the site vast.ai, using the best GPU, the world ever made, like RTX 3090 or RTX 4090, I can't use the CPU.

I assume the power the CPU can give is really small compared to the GPU. And hashcat make the decision to not use it.. But... If it even add 1% more, the price I will pay in the end will be the same for me (you can say someone will spend more electric energy because it).

Is this a kind of Tragedy of the commons? If it uses the CPU, the electric bill will be bigger and at the end, the rent price will increase for everyone and what I gain will be a small % of the brute force power? Or I just need to install something?

Why I can't use GPU and CPU at same time in this cases?
