This is really backwards. Most open source developers release their code then take donations. He can keep his ransomware. I'll take my business elsewhere when competition becomes available.

I will donate 100btc only if it works on Ubuntu 10..4
with a nvidia gfx9800 gx2.

So, how much interest is there in this? I *could* put a little effort in making something a bit more generic than my osx version, and I don't even need a bounty or donation. It's a simple math problem, as the coins I'd need to ask to make this monetarily worthwhile are simply not going to be offered, so I'd rather do this for the community's sake.  Donations are appreciated, but judging by how much I got from the implementation I posted (a hefty sum of 0), I don't think that is going to tilt my balance anytime soon

On the other hand, are there any takers? I'd offer my support and my code to whomever wants to make this happen in a short period of time.

Presumably he's not going to get 10,000 BTC very rapidly, by shaving off 5 BTC from each gen.

"It is OpenCL"? I'm guessing the bounty starter meant either cuda or opencl, but although I only have nvidia (and cuda is so much less verbose) I think an opencl version would be more appropriate.

Just hijacking the thread a little bit to say I've posted a new patch to enable CUDA on the default client: http://bt.irlbtc.com/view/1009.msg13028#msg13028

Still very specialized, but wide open for you to change that

The same license as the rest of bitcoin.

Introducing new licenses into the mix just brings additional headaches.

I certainly won't turn down donations...  (see sig)
