Can Cudaminer do sha256 ?
wanna mine against TH/s asics ?
yes it can, but it's not worth it (also I don't know if there is one or two loop of sha256... which doesn't change anything actually)
I think it is doing stuff around 300MH/s (say some optimization could double it or quadruple it... it would still be 1GH/s against several TH/s machine (not farm) so unless it is a ninja launch and you are the only one aware it, you don't have a chance to get a block.
And if you get one, it will orphan...
yep
your right djm34. one 750ti would get about 2 coins a day. on sha256 coin.
But if the ti is used to predict the outcome of the final hash, you might not need to compute all the hashes. Then the TI beat the TH's asiscs.
Predict -> verify (cpu)
?
CCminer is a bruteforce miner. It will try all the combinations. If an intellegent miner could exclude some of the combination and make guesses, the 750ti could be used to run this prediction code instead of the bruteforce code. Then you could beat the performance of an TH Asic.
based on what ?
unless you have the reciprocal (?) function of sha256, you are rather screwed...
The best thing you could do would be to discard nonce from the scan on whatever basis, but you are likely to loose good solution too (so unless you are able to keep the probability of discarding a good nonce small (like for jackpotcoin... well actually it doesn't discard nonce, but don't examine certain algo chains... because the hashrate rate of the various chain is unbalanced), you are again screwed), or manage early exit from the function loop in case of early hint that a nonce can't lead to the solution. (actually that would be your best call... ccminer miner with a neural net (or multivariate analysis of some kind... this wouldn't be fast for sure
) would certainly be fun but I don't think it would speed up things... training, or computing decision variable aren't really fast...)
edit: something funny, is that nobody came up yet with a coin using 2 nonces (or two non-contiguous random words to find)... I am pretty sure that would be many things resistant...
