We have a ethminer ready that supports cuda and opencl for windows. And ethminer for GNU/Linux..
But these are pretty untested. We have to make a decision here, either we release with untested ethminer and hope for the best or we have to postpone again.
We are very sorry.. but things like this must be done right, fair without trouble. What do you think, the community? We are worked 14 hours straight on this release now..
If you have cloned ethereum then everything is already there.
there is a cudaminer already existing.
