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

[Amph]

it's strange, the program start only with bitcoin, but not with litecoin...
with litecoin it give me an error

This is meant only to work with litecoin not bitcoin

yeah i know, this is why it's strange, maybe can be that i connect to stratum, using p2pool?

What command are you trying to execute? are drivers up to date?

i'm using p2pool,
i run litecoin client, then p2pool with "--net litecoin", and then cudaminer, but it say fail to execute or something, and then restart in  15 sec

I've added a lot of results for a EVGA GTX 680 to the Google Docs.

Big difference in kernel selection between interactive and non-interactive (S-kernel)

Thanks for this miner!

[cbuchner1]

Big difference in kernel selection between interactive and non-interactive (S-kernel)

interactive picks smaller kernels that complete within 1/30th of a second. And then the CPU pauses for a millisecond (actually twice per hash computation, once inbetween the A and B kernels and once after the B kernel), giving you about 60 frames per second for doing other stuff, like watching movies.

[CumpsD]

That explains the difference

Using the interactive auto-tuned setting with not-interactive (so without letting it re-tune) had a nice effect of increased rates, without much lag.

I guess it choose a small kernel which completes fast, but then doesn't pause the CPU.

[cbuchner1]

When using the autotuned setting from non-interactive mode in interactive mode, you get higher hash rates. The CPU will still pause inbetween, but the computation takes longer. So the ratio of computation vs. pause is higher -> more hashes/sec at increased lag.

When using the autotuned setting from non-interactive mode in interactive mode, you get higher hash rates. The CPU will still pause inbetween, but the computation takes longer. So the ratio of computation vs. pause is higher -> more hashes/sec at increased lag.

Makes sense. What I tried was the other way around actually. Using the autotuned setting from interactive in non-interactive. (Just for testing, now I've moved on to the more correct settings)

[cbuchner1]

I am currently a bit concerned because large block configurations like 56x8 or 64x4 cause results to not validate on both of my 560Ti cards. Even with texture cache turned off. I wonder what I broke and when that happened. UPDATE: okay, this must be the memory requirement - my 560 cards aren't blessed with 3Gigs of VRAM.

Anyone had any luck with the GTX 260, I had an old one lying around which I chucked in a test machine but can't get more than 20kh out of it.

Looking at the stats for other cards I am guessing 20kh is probably about right.  My 460M in my laptop is about 50kh, in the google doc from page 1 there is a 210 and it gets about 6kh.

I get 44 kHash with Windows 7, cudaminer Version older than 2013-04-30 using

-i0 -l S27x3

It should work a bit faster on Windows XP or Linux

Help, how can I slow this down on my GTX  570 - it's running over 90 degrees...

My command line:

cudaminer -o http://ltc.crypdough.com:9332/ -u user -p pass -i 0

For one, -i 1 helps a little (you lose some 25% of hashing speed on fast cards)

Or use a tool called nvidia-inspector

-Set the fan to Manual and higher Speeds
-clock down the card's core speed and possibly undervolt a bit.

I use MSI afterburner on my (non-MSI) GTX 570. It allows you to redraw the automatic slope for fan speed.
You can find it here: http://event.msi.com/vga/afterburner/

Trough settings-> fan you can see the graph and adapt it.
I've set 4 point for my card:

• 30% at 30°
• 55% at 60°
• 85% at 80°
• 100% at 100° (but the Club3D GTX570 I have only goes up to 85%)

I set the fan update speed to 5000ms and a temp hysteresis of 1° to avoid constant 'flapping' of the fan speed.

This is running 24/7 at around 70° at 70% fan, with these options in cudaminer: -i 0 -C 2 -l 30x8, giving me around 226 kh/s.
Hope this helps!

edit: BTW, I run this GPU dedicated for mining, my desktop is using the internal graphics of my i5. If you are using your desktop on the card, I suggest using the -i 1 option.

So my question is disabling longpoll a recommended practice where it is an option?

From here it does seem longpolling is an extra protocol that doesn't bring any benefit for using local stratum proxy: https://mining.bitcoin.cz/stratum-mining

What speed should I get with a GTX 460M

or a GTX 680

check here

that should give you an idea

yay 185khash with 680 not overclocked.

now how do I get the miner to connect to COINOTRON?

Hi this is how I do -- just tried and it works

download  http://www.wemineltc.com/files/stratum_proxy.exe 
Put it in your cudaminer directory.
Note that there are different versions on the net.

Run this to start proxy

Code:

stratum_proxy.exe -o coinotron.com -p 3334 -pa scrypt -nm

Run this to mine

Code:

cudaminer -o http://127.0.0.1:8332 -O username:passwd -d 1 -l 112x8   -i 0 -C 2 --no-longpoll

You should change the "-d 1 -l 112x8   -i 0 -C 2 " to suit your card. Use -D to find out the best -l parameters.

Hey :-)

i got a "result does not validate on CPU!" after starting cudaminer (after try (start) stratum_proxy) .. (coionotron)

what does that message mean?
