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

It is the same but we want to use a custom algorithm that has an advantage for nvidia cards and less of one for amd.  Would even out most of the cryptos being massively easy on amd

An NvidiaCoin... I'd back that!

I think the idea of making a CUDACOIN is absolutely superb. And if we say that nvidia is going to backup the coin with offers and promotions ( which might happen) it will be a grate success. When you buy an nvidia card you will receive as a bonus 5 cudacoins not a useless game. Everybody will be happy. I think you could suggest this to your nvidia guys Christian!

Christian from what i posted in this post

it doesnt seem too hard to create a new coin, obviously i dont know coding and even i was able to find it
again those details were taken from the maxcoin wallet

Careful nVidia and CUDA are both trademarked, and trademarks can trump coins (hello Coinye!)

Better to choose a name like nvCoin or something else (however the short name NVC is already taken by NovaCoin)

yes, clonecoins are easy, but actual innovation of features that haven't existed before is hard.

there is even a web site that automatically creates your personal crypto coin clone for a fee.

yes, but if you can figure out the difficulty system, and go through and follow the block rewards system, it should be easy to integrate the airdrop
Currently the code can read your wallet balance, so if you programmed in predefined periods from the genesis block time,
then follow the rewards system you could then give rewards everytime the wallet gets to that time or above that time.

It would mean it would need to check a block index to see how many coins the wallet had at a given time, incase the wallet was not on during the time of the air drop.

I have no programming knowledge sadly. But I sure has he'll would like to learn and help

Anyone mining a scrypt-jane coin on their 750ti with Nfactor of 11 or higher? Keep getting bsods on mine with cmd line of: "cudaminer --algo=scrypt-jane:CACH -d 2 -o stratum+tcp:...." Using release 2-18-14. If you are can you share what your launch config is? Thank you.

Are you running the x86 or x64 version?

I get bsod when running the x86 version. It only does it on my msi 750ti. It does it if I running regular scrypt. I get the Nvidia driver error for the bsod.

Hey thx for your reply I just tried running the x64 version and it still causes the bsod. Im thinking I might have to launch a specific kernel for n11 with my 750ti? or revert to an older release of cudaminer to see if that fixes it. Odd because my 660tis run nfactor 11 autotune no problem with latest cudaminer and x86. Might be a conflict between nivdrivers, autotune or the nfactor with the 750ti im not sure.

CudaCoin is great idea. But how to make it ALMOST Cuda-only? So we would finally have advantage over AMD. Is there any algo that cuda is better than amd by more than 5-10%?

It would need a new custom algorithm writing

use a hardware instruction that is implemented in HW in all nVidia GPUs in a very specific way, but not on AMD
and embed it in a well known hashing algorithm.

e.g. some transcendental functions exhibiting a very specific rounding and precision behavior on nVidia
(integers numbers can be reinterpreted as floats and vice verse with the __float_as_int and __int_as_float intrinsics)

Obviously they are paying attention so couldn't your nVidia contacts run this idea up their chain of command? Fuck the Moon! With nVidia's backing this could get to Proxima Centauri :-)

[cbuchner1]

Strictly speaking you could design a coin that only runs on HP calculators and with all the backing from HP corporate you couldn't even get it to low earth orbit.

Explain why it's different with nvidia (OK, their calculators are slightly faster and green).

LOL. Love the idea of it being tied to card purchases and things like that. Other than that I'm not sure... Surely a coin backed by the marketing machine of a multi-national multi-billion dollar corporation must be worth more than a coin based on a stupid Dog meme? Would think it would also awaken more nVidia miners just as cudaminer has.

[cbuchner1]

the blake implementation should approach the threshold of being usable now. You need a build made from github source code.
Use the same kernel launch configurations as you did with keccak, except that the T kernel now goes up to 32 warps when
using blake.

My 750 Ti gets 295 MHash/s. My GTX 780 churns out 580 MHash/s with some OC.

AMD still seems to be significantly better here (similar to keccak)

Some launch configs

--algo=blake -L 512 -l K1000x32   Kepler Compute 3.0 devices
--algo=blake -L 512 -l F1000x32   Legacy & Fermi, but try this on Kepler Compute 3.0 devices also and compare. It uses the generic implementation.
--algo=blake -L 512 -l T1000x32   Kepler Compute 3.5 and Maxwell Compute 5.0 devices

Is there any profit in this blakecoin?

[Decagrog]

I've read a good portion of this thread cannot find a solution to my problem, so sorry if you already talked about it.

My setup:
- 5  Gainward 750 TI
- asRock 970 extreme 4 ( already tested with 4-5 ati cards )
-  AM3 dual core
- 4gb ddr
- ali corsair 850ax
- 1x powered risers with usb cable (like that one http://i01.i.aliimg.com/wsphoto/v0/988441113_1/PCI-E-PCI-E-Express-1X-to-X16-Riser-Card-1M-USB-3-0-Extender-Cable.jpg )
- windows 7 32bit

- settings: -l T5x24 -C 1 -H 2 -i 0
- all PCIE slots 1x with presence mod


The problem:
-With 5 card running (2 on riser, 3 on the 16x slot) the hashrate is awful, about 20-40kh/s for each card. The cpu run at 100%
-With 4 card running (1 on riser, 3 on the 16x slot) the hashrate is just a bit better (3cards at 110kh/s and one at 60kh/s. The cpu run about 20-30%
-With 3 card running (3 on the 16x slot) the hashrate is almost fine (3 cards at 265-270kh/s) The cpu run about 70-80%

Now, some people runs 5 cards with a dual core just fine (both intel and amd), it's strange to me all that cpu usage even with the -H 2 parameter enable
The 1X slots  seems to be the culprit, but again, still didn't found anyone with that issue...can be a problem related to the motherboard?

Any suggestion is welcome!

What taskmanger says , that cudaminer is using this 100% cpu?

[Decagrog]

Aarrgh  wait...I've just connected again the 2 cards with the risers to check if is cudaminer.exe taking all the cpu and now 4 cards run fine at 265kh/s and 1 (with the 1x riser) is not visible...cpu usage still to 20-30%

Checked the cable and rebooted : now again with 5 cards and the awful hashrate, checked the processes...is not cudaminer.exe the cuprit but teamviewer (the rigs is headless and I'm working remotely)

Just the time to return at home and I'll try with  teamviewer disabled, thanks for pointing me to the right way

Other then that make sure you pass -H 2 in your launch config

I just ran the blake algo on the blakecoin pool
The gtx780ti seems to run at 971Mhash/s, however all shares are rejected.
Debug gives this reject reason: H-not-zero
