OK, next week I will start some research how to include GPU libs to miner, so stay tuned. IMHO source of existing miners is pretty understandable, so we could have success, I'm optimist here :-) GPU mining in my calculations should be 4-5 times faster on CPU. Of course miner source will be fully open source.
Of course If somebody do some investigation or have sample code, please share out with your work
If you like my idea - please donate
