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

[cbuchner1]

The single memory switch turned on (-m 1) reduces my max total warps from 181 to 118 (for N 14 SJ, L 3), but it's needed for any texture caching (-C).
Is it supposed to work like this?

1D textures have a size limit on their X dimension. That restricts us to 2 GB.

2D textures much less so (because both dimensions X and Y can be quite large). Try using -C 2 instead.

Single memory allocation may be severely limited by the Windows WDDM driver model as well. It should still be able to grab most of your card's memory on Linux though.

So what are them overclockers getting out of a 780, Titan or 780Ti using the new Z kernel?. Have we hit 800kHash/s yet?

And considering the demise in YAC to BTC exchange rates... are there any other profitable scrypt-jane coins that we could mine? If some of you could share some firsthand experience that would be great...

I have been running it with very decent gain of about 17% over the 12/18/2013 official binary on my Titan.

[ghur]

I build myself a binary of revision 295d239459e45cb6179655c02d82cd7974055088. (I'm not crazy enough to download a binary not compiled by the original author)
I've been running it for a day now mining scrypt.

I have Gigabyte 670 with a factory overclock to 980.

On the latest stable release:
Autotune with no other arguments landed on K14x16, which performed around at 285 khash.
By fiddling with some settings (-H 1 -i 0 -l K7x32 -C 0 -m 1) I got it to run at 300-ish.

Using the binary I compiled myself I found using the same settings as before the performance dropped some. (Don't recall the exact figures unfortunately).
However, I can report using "-H 1 -i 0 -l Y7x32 -C 1 -m 1" I got it to 330-ish at the same clock.
Deciding to push the GPU some more, bumping the clock to 1060 (I love how stable the temps are on this card), it starts running around 350-360 khash/s.

Another thing that changed, with the latest stable I get the best performance out of the 64-bit binary. Using the custom build, the 32-bit binary performs significantly better.

In a nutshell: new nvidia kernels are great.

Hope this helps

I'm currently on Vertcoin it's going up nicely.

-m 0, -C 0 uses up to 1963 MB, while anything with -m 1 (C 1/C 2) uses 1287 MB max. Anything above that crashes.

NVIDIA System Management Interface says that my card is in WDDM mode:

Code:

+------------------------------------------------------+
| NVIDIA-SMI 331.93     Driver Version: 331.93         |
|-------------------------------+----------------------+----------------------+
| GPU  Name            TCC/WDDM | Bus-Id        Disp.A | Volatile Uncorr. ECC |
| Fan  Temp  Perf  Pwr:Usage/Cap|         Memory-Usage | GPU-Util  Compute M. |
|===============================+======================+======================|
|   0  GeForce GTX 660    WDDM  | 0000:02:00.0     N/A |                  N/A |
| 42%   34C  N/A     N/A /  N/A |   2005MiB /  2047MiB |     N/A      Default |
+-------------------------------+----------------------+----------------------+

But since the card is a secondary card, and I couldn't even attach a monitor if I wanted to due to my mobo not supporting it with the onboard graphics, there's not much info SMI can gather.
Anyway, is there a custom driver or something that would let me use the card purely for it's computational power without limitations?

Well not really:
ZcC is in N 13 but it's recovering from a fork for a while now so no exhchanges at the moment (enters N14 on Febr 17);
CPR (Copperbars) is in N 13 as well but I dropped it for some reason, not sure what I didn't like about it... (enters N14 on Febr 21);
APC (Applecoin) has potential, but it's only in N 11. Looking at one of the pools, the average hashrate per worker is around 294 kH/s. My GTX 660 gets 59 kH/s and ~30-40% CPU utilization (with -H 2).
Also, there's a bunch of coins between N 4 and N 7 but those are pretty much hit and miss. (cachecoin, microcoin, internetcoin, qqcoin, velocitycoin, freecoin, etc)
Basically, I'm silently waiting for the Keccak optimization so that I can test the !%+ out of low N coins because I'm starting to dislike YAC a lot and there's no way scrypt is more profitable with low-mid range cards like a GTX 660 (260 scrypt khashes vs 3.4 SJ N14 khashes).

Just found this interesting project: http://code.google.com/p/gpuocelot/

Seems that its possible to run CUDA Programs on any graphics cards.
Would be interesting to see how cudaminer performs on an ATI card...

[sambiohazard]

Hi guys I guess there is not much development on legacy kernel (GTX 275). I was planning on getting a 650ti or 660. What would you suggest? I am restrained by budget so these are the best i can afford atm.

Check the spreadsheets for yourself or just take my word for it and go with a 660.

@ozie: what hashrate you're getting for vert and with what card?

Thanks for the quick reply. Will buy this asap.

How do I change the port in cudaminer batch file? I can only seem to use one particular port. It's been bugging me for awhile because it's a nightmare when I want to switch coins.

may be advantageous to switch to  microCoin?

If you doubt its safety, don't use it, and compile the code yourself.
Why is YAC suddenly deemed "dead"?
I have been mining LTC with the Z kernel, trying to get me 1 LTC...

The 32 version didn't work for me and the 64 keep sending error message...

@ozie: what hashrate you're getting for vert and with what card?

Im getting 190 kh/s with an 680 and the Nvidia Kernel Y8x24 on x64 cudaminer and win8.
the card currently runs at 1241 core and 1460 memory clock.

Strangly i dont see any hashrate increase when i switch to -i 0 with the NVidia Kernel.
I will try the 32bit version later on.

[liomojo1]

i ve got 140 max with gtx760 , gpu-1136mhz mem-1550 and 1152 cudacores with bat file like this :
cudaminer64.exe --algo=scrypt:2048 -i 0 -l Y6x32
sadly this is the maximum , if you have any suggestion please make them.

Everyone has an opinion   I'm actually buying hardware specifically for YAC at this time.  Beave162 and I have been tweaking and tuning for a few weeks now.  Returns have been good so far - the coin is slightly undervalued right now, so everyone is being advised to hold them
