I think I can optimize this. Who wants a faster miner? Anybody willing to donate 0.1 BTC?

Note that tsiv merged my changes and worked more on it, I think. But I'd be interested to see what you come up with.

My uint keccak implementation is doing 172MHASH on a standard 750ti. Yours/tsivs doeas 115MHASH (in the cryptonight fork).
So mine is 50% faster. (the sourcecode is in my mod)

Keccak is hardly used.

Is this still the CryptoNight miner for CUDA? I noticed that it's not been updated in a while, but I just built it under nvOC v17. With three 1070s underclocked a bit, I'm seeing about 1.35 kH/s. Is this about in the ballpark of what I should expect? Is there a newer miner for nVidia GPUs that I should be using instead?

Edit: This thread refers to this fork of ccminer-cryptonight, which is pulling 2 kH/s across three 1070s.

Simple question: Aside from just choosing a different User/Computer name, for the mingw shell, how do you deal with a _ underscore in a name? It displays as a "space", which is bad. I used Visual Studio last time, but I'm trying to keep the build as small as possible. Can you use cygwin instead?

I've only built in linux

does the donation give me access to future improvements?
does it compile nicely in ubuntu?

Yes, my donators are on a list that will recieve future improvements. The sourcecode will be sendt as well on a later stage.

Cool! Well, when the cryptonight mod is linux executable / compilable, let me know. Thanks for putting the effort in!

Cryptonight sp-mod version 1 exe file has been sendt to the donators. My first afternoon of work gave an increase of around 10% on the 750ti. This will increase in the next releases.
If you want to join the train please donate 0.2 BTC and recieve both the optimized Spreadminer (with source) and the Cryptonight mod.
my BTC adress is in my signature.

The spreadminer comes with sourcecode and can be compiled on ubuntu. The cryptonight miner is win32 executable only for now.

I don't have the hashrate yet, since I haven't started. I have just read the code and prepared my changes.

ah, ok, based on

I am happy when it beats the speed of the claymore miner on the 290x. (GTX 980)

i thought you already have a working version, but I guess you meant "I will be happy" as opposed to "i am happy" .
lost in translation.

Well my keccak implentation is 70% faster, so I have already started I just need to merge the code into the branch

But there is a lot of code to go through, and keccak is only a tiny bit of the total hash.

felll gimme a price cause im liable to buy another GPU unless things get more efficinent....................

does spreadcoin have a shapeshift-like service that I'm not aware of ? Or do I gotta go through exchanges?

I will start on this now.. Private kernals.

Donatation limit is set to 0.2 BTC.

The spreadcoin donators will get a discount of 0.1 BTC

Any multipools mining this with payout in BTC?

I see some possible major improvements in the code. 10% gain is easy 30% is possible

probably me!
depends of what hashrate you can reach.

im in too, depends on the hashrate. My 750 ti's get 280ish on a straight pipe (PCI-16 on the board) and 250 using a riser
