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

[Nitsi]

Been mining for 8 hours now with GTX 670 @ 108 000 kh/s, found 2 blocks so far, maxcoind.exe getbalance, shows i have 192 coins atleast, so i guess they are confirmed

WTF  from yesterday evening to today morning 40 new pages of text in this thread....

[cbuchner1]

Why does this show hashrate so high?  

run one cudaminer per graphics card. something is wrong with the multi-GPU support for maxcoin.

considering that my balance is now around 2000 MAXcoin and they're worth a fortune,
you might want to excuse a few extra pages in this thread...

this is a BIG DEAL for the cuda community.

[liomojo1]

This coin is crap , but it is fun to test our cards and see 99000khs/s for a 760gtx hehehehe. I reverted back to microcoin.
I like the milions there.

I've running both GPUs on one .bat file... is it better to run a separate bat file for each GPU as someone mentioned? The hash rates seem the same. I was finding blocks, albeit no where near as fast as earlier when I was running 2 separate instances.

PS - thanks again for your hard work on cudaminer... We all made a bunch of money thanks to you today.

[relm9]

wtf are you running doing 500 mega hashes ? 500000+ kh/s ?

and i figured best performance i think based on usage for me 9400GT is
cudaminer -q -C 2 --algo=keccak -d 1 -i 0 -m 1 -L 128 -l F64x4
seems to be working ok.. about 80% usage and my desktop is not getting laggy while i watch WMC TV ep's
not sure if there is some other command for those old cards or if they are even suppose to be supported lol

and hey no one answered me either is 0.0mb per warp always normal ?
and is my card always stuck in middle power mode normal ?

scantime ? run it with --help command guys
its there for a reason ..use it

2x780 and 3x770

[Spoetnik]

is all your cards stuck in middle power mode ?

edit:
nice i wish i had your 5 cards lol

multi-gpu support is a hit or miss with keccak algo. I have been getting crashes (out of memory errors)
when trying more than one GPU per instance. So I am running them all in separate windows.

I made a bunch of money too. Cannot complain. Power costs have become irrelevant.

[aikklond]

I have 2* GTS 450 getting 27-30 Mh/s. Havent found anything with cudaminer since the beginning.

OK guys i am using this command without knowing what any of that realy means!!!

cudaminer --algo=keccak -d 0,1   -o http://127.0.0.1:8180 -O user:pass -C 2 -l F1000x16 -L 256  -H 2  -m 1  -R 5 -i 0  Huh



should I change something from these settings???  -C 2 -L 256  -H 2  -m 1  -R 5 -i 0

Please  help with that!

Alright cool. The .bat files are the exact same except one has -d 0 and one has -d 1, right?

You are going be receiving more from me as soon as I can fight my way out of coins-e...
Once again, thank you so much for your efforts.

ok i figured out what my GPU speed issue was..
my custom Aida64 OSD was reporting the speed from another card and i forgot

[cbuchner1]

As best I can tell the 1gh patch simply uses OpenSSL for the stratum sha256 calculation. Here is the patch for Cudaminer although 1gh is still funky, they hardly ever accept shares even though you're cranking away forever. Also keep in mind this make break it for other stratum (ie. maybe it's 1gh that is broken, not cpu-miner).

thanks this is good information.

let me propose an improvement. sha256d for anything but keccak, and SHA256 otherwise

Code:

	/* Generate merkle root */
	if (opt_algo != ALGO_KECCAK) // CB: fix for 
		sha256d(merkle_root, sctx->job.coinbase, (int)sctx->job.coinbase_size);

You experts here will probably laugh me out of the forum, but for all those who haven't tried this...

I downloaded EVGA Precision X and simply started the executable (without touching any knobs or sliders) while solo mining Maxcoin and got a 50% improvement! The temps went up a few degrees to around 79-82degC.

Waiting on coin-e to sell. Christian I have some coins coming your way in my next block

[Tamis]

Do you people get a yeah! when solomining ?
Mined all night with a gtx 670 at 110mh/s and nada :/

[bscoin]

I'm a bit confused.

I have a  GTX 560 Ti

With  -l f25x23, I get 294501 khash/s, but the GPU is hardly in use.
With -l  F1536x16 I get some out of memory errors at the start, but it works, giving me 75284 khash/s. The GPU is using about 80%

Is the f25x23 doing it's job?

Thanks

How to compile? I tried to compile in VS2012, but I get an error

[fr3q]

Hi All,

I think I have this working but not entirely sure.

My BAT file:

Code:

cudaminer.exe --algo=keccak -o http://127.0.0.1:8108 -O USER:PASS -s 1 -l K1000x32 -L 128

This is my maxcoin.conf:

Cudaminer is reporting that it is hashing but all I see in maxcoind's debug log is like this:

Is this working?

EDIT: This config is working, I just received a block    

Thanks
