[ANN] cudaMiner & ccMiner CUDA based mining applications [Windows/Linux/MacOSX]

[see360]

How different is the groestl implementation on myriad coin? Just for the fun of it I connected to a groestl pool (ccminer.exe -R 3 -s 1 -a groestl -o stratum+tcp://stablehash.com:4502...) and of course it is all boos, but I can dream :-)

I assume cudaminer honors reconnect requests because a quick 'grep shows that it has logging code for a reconnect message.  Given the man-in-the-middle/spoofing attacks going on with several of the pools, there should probably be a way to tell cudaminer not to accept reconnect requests when started with a particular command line flag, and optionally to log the reconnect data or report it in some way.

is there a thread where I can read more about man in the middle attacks with pool mining?

It's happening on a bunch of pools.  So far I've heard: cleverminer, wafflepool, multipool.us, and others that I'm forgetting just now.  The wafflepool thread has some extensive discussion about it, protocol captures, etc.

I see people are now working on patches for other miners (just got back from dinner so I'm catching up):

can someone help me run a fall over config?

also if the first pool comes back on does it switch back to the first one?

[djm34]

here a rough idea (found that in some bat of 1gh)
In the bat file:

:loop
cudaminer pool1  -r number_of_time_to_retry
cudaminer pool2  -r number_of_time_to_retry
goto loop

It won't switch back if the first pool get back online, it switchs only if the pool get disconnected

Skimmed through it. It isn't clear to me is cudaminer even actually impacted?

All miners that respond to "reconnect" messages sent by the pool are impacted, which is most of them....

im a noob and dont know how to fill this out

I've tried looking but so far it's been a fruitless effort...

Is there a miner available which allows Nvidia cards to mine Darkcoin?  If so, can someone point me in the right direction?  Thanks guys

I found SGminer which appears to work, but I'm getting less out of 5 750 ti's as I get out of 1 ATI 6950.  So I guess I have to rephrase my question to, is there a miner that can competitively mine Darkcoin for Nvidia when compared to AMD?

I cannot confirm this here.

For me the release ccminer v0.3 binaries are 30% faster than the Windows build of sph-sgminer that I downloaded
from crypto-mining-blog

But yes, groestl is hard to optimize. It's a complex beast.

what makes Darkcoin so interesting? Why do you want us to consider it?

It's 11 hash algorithms, of which we only have about half implemented so far. So it would mean a LOT of extra effort for just one coin...

Yeah, it is just one coin.  But I believe Hirocoin also uses x11 and I know Aircoin(Although that fell flat on its face) was considering it.  I didn't want to imply that you should drop all current development on other projects, I was just looking to see if anything already existed.

I've seen some folks claim it is a viable solution to some of the looming threats coming from scrypt asics, but I don't understand this enough to weigh in with any kind of technical know-how as to why that is.

I'm drawn to it because it seems to have an extremely involved dev and during this recent bear market in alts it has remained at a remarkably steady exchange rate. 

[djm34]

Beside the X11 coins themselves, I think it could be interesting to have all those algorithms coded (I know it is easy to say when you are not the one doing the work...). Most of the times these algos are used to make new coins. That would clearly be an advantage on the long term.

I have no idea whether this is trustful or not - just wanted to share the information with you!
