I will of course provide a bounty to having an open source AMD miner, I believe we need one. Is the CUDA miner opensource? I know there is an optimized CUDA miner for people with big rigs(at least I heard there was), but we need this stuff open to the public and get it more decentralized.

I would provide 500-1k XMR additionally for a bounty, easily, for helping GPU miners get more involved with Monero.
