GPU support

[ghost]

Is there any possibility of an option to utilize GPU power to generate the rai addresses? If I'm not mistaken it's an order of magnitude faster.

probably theoretically possible. I have no idea how though, i've never done any GPU programming

For my reference, Sia uses blake2b to hash, and there's a golang GPU miner implementation here https://github.com/robvanmieghem/gominer

I developed my own NANO vanity address generator with GPU support here: https://github.com/PlasmaPower/nano-vanity

It's also significantly faster on the CPU (though by default, it uses one less core than available).

I didn't know the name of this one when creating it, so unfortunately they're both named the same thing.

yes, Plasmapower's GPU vanity generator works great!
I requested him to add seed generation to it (had key generation only before) and he added it super fast and it works like a charm! (use --generate-seed for that)
