I think it was a attempt, work in progress. Does not function correctly. That got me started on attempting to display the current key it was working on as it was running. As well as attempting to modifiy it to start with the fisrt 20 or so known keys for tests. I know of no current Pubkey search program for the puzzles with GPU. The upside of GPU searching is the speed for video cards seems to be x2 the speed with more then 20 hash160 addresses. More fun right now then anything, always trying to learn.
