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

[italeffect]

I have a few 750ti x6 rigs running Windows 8.

I've always used EVGA Precision X to overclock and set fans. I recently discovered that if I open Precision to set the clocks and fans, launch ccminer, and then quit Precision - the hash rate goes up. Of course I loose the fan control but the overclocks stay.

Any theories on why this is? I first though maybe CPU, but it's never using higher then about 35% with Precision running and about 25% just ccminer running. Ram usage is about 30% of total.

On x11 it's the difference between 17.2 MH/s or 17.5 MH/s for 6 cards.

The reason is that Precision X adds a few hardware locks when doing the hardware monitoring & particularly the software fan controls. You can tweak the settings in Precision X to make it less noticeable, but for the absolute maximum hashrate, you'll need to close Precision X...

I have released the 3rd public beta of my forked ccminer.  More free hashpower. Check it out

Decrese the polling rate to like 5000 ms.

Not sure if this is already posted on this board. (So my apologies) but this is a very interesting read and history of XMR mining...

unfortunately this time seems to be over...

Actually...Gapcoin may be the next big opportunity to do this same thing right now..at least for an early GPU miner..and since it is dealing with primes..and Integral approach might blaze...

Is it on an exchange ?

Also here....  https://coin-swap.net/market/GAP/BTC

BTW Gap supporters ARE interested in a GPU miner...trying to reach a mathematical world record, very interesting stuff at least. Fairly profitable at the moment as well, I can only speculate where it might go if that world record is achieved. And if it doesn't go anywhere at least it is an interesting endeavor as opposed to a useless one.

Not sure if all you miners from Europe have seen this but here you go: http://www.ecoinmining.eu/news/bitcoin-wallet-platform-coinbase-opens-europe/

Quote from inside article "The 13 countries Coinbase is adding include Italy, Spain, France, Belgium, the Netherlands, Austria, Cyprus, Finland, Greece, Latvia, Malta, Portugal, and Slovakia."

Thank you (and bathrobehero). Such an obvious reason.

say I want to multiply by two some big integer (256bit ie 8 uint32_t)
What would be the fastest ?

* multiplying by 2 with mad/madc ?
* just adding the numbers to itself ?
* shifting with shfl/shl ?

in terms of number of lines of code it seems to be more or less the same...

Sooooo, what have i missed?

Been a while since i checked in here, I don't get notifications any more for some reason   but yehhhhhhh. How's everyone doing?

Excellent thanks.  Wondered where u had got too.

We have had GANJA, DANK, FTC switching to Neoscrypt (with great profit on day 1).  Devs have been working hard too, a couple of new miners have been released.

Shame BTC keeps tanking.

Yeh the bitcoin price drop is a killer

Is there any working neoscrypt miner with cuda support?

Second article. It will work for you.

Thank you very much for the fast reply. Here comes my next question, is anyone working on neoscrypt mining with cudaminer?

From the Programming Guide:

32bit multiply: multiple instructions
32bit add:      128 operations / clock cycle
32bit shift:     64 operations / clock cycle

But I think in reality it's more complicated than that.

I think they are the same.

But
 If we use the divide and conquer algorithm proposed by Dr. Fürer described here: http://wwwmath.uni-muenster.de/u/cl/WS20078/mult.pdf

Modular Multiplication. Maybe?
