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

[cbuchner1]

Just noticed the news about scrypt-jane. I have a 650ti with 1GB DDR5 RAM. Will performance be substantially better in Linux? I only have Windows now and isn't compiling the test version to run, but want to plan ahead a little.

BTW, is the cuda miner equally advantageous compared with ATI cards in scrypt-jane whether the N is high or low?

1) probably slightly better than on Windows. The more RAM is on the card, the bigger the difference becomes because Windows for some reason starts slowing down once you try to allocate a lot of RAM on the GPU.

1GB is on the very low end. You want to use a -l K 7x1 launch config here.

2) I haven't tested anything other than N-factor 14 (32768) so far. I believe I can keep the advantage through factor 17, but it will require more and more powerful cards over time... And I think it's just sloppy optimization or programming of the AMD OpenCL code that causes CUDA to be faster here.

What do you think is a profitable scrypt-jane coin at the moment, we are all talking YAC, but there are others.

I have not researched this yet, and the support for different coins is still missing. will get to this tonight....

Well i;ve got the client for YACoin, Pennies, onecoin, applecoin and tickets. they are all taking their time to download.

[patoberli]

I actually never got the opencl miner for yacoins running on my radeon card at home. There also seems to be absolutely 0 (zero) developing being done on the miner.

You guys are unfair, please someone explain how to compile and start tryin' scrypt jane :-(

Oh yeah u true, sounds like i'm blind today

Well I cant find the link to the scrypt-jane download. Anyone have a link handy to the relevant post?

Multiple coin support for scrypt-jane! Let me know which others you want (see above code to check what's available)

--algo=scrypt-jane

directly specify N factor 12
--algo=scrypt-jane:12

mine Freecoin (likewise for other coins)
--algo=scrypt-jane:FEC
--algo=scrypt-jane:FreeCoin

The most flexible way: specify parameters for Gold Pressed Latinum manually
--algo=scrypt-jane:1377557832,4,30

Note that N factor changes during mining will most likely lead to a crash. You have been warned

Am I doing it wrong on a GTX 660 2GB?

-a scrypt-jane -d 1 -i 0 -l K10x1 -C 2

Getting 0.48khash/s anything higher than 10x1 gives me the too much memory error.

Awesome, thanks for adding this.

Have you tried out QQCoin? If so what hash rates are you seeing? With a 780 under Windows I max out at 55kH/s which is a lot lower than the 1.8 MH/s my 7970 gets with ybcminer. I'm just wondering if it is less efficient with lower N factors or something. That said someone else here mentioned they could open up multiple instances of cudaminer and it didn't lower their hash rate while mining QQcoin, for me it just halves it though.

-a scrypt-jane -d 1 -i 0 -l K10x1 -C 2

Getting 0.48khash/s anything higher than 10x1 gives me the too much memory error.

Got my -d 1 card to work but using both cards does not work. -d 0 card crashes and only works in -i 1 mode.

getting 1.76khash/s out of my second card though.

yes, I've noticed with scrypt-jane that mining on more than one GPU in a single cudaminer instance will crash it ( at least on Windows)

Solution is to open up two instances and assign one GPU to each, that worked for me.

[69charger]

Thanks I'll try that. Using bathrobehero's -C 0 K14x1 setting I'm up to 2.46 khash/s

The Kekkac part is heavily CPU bound currently and entirely unoptimized... So low N factors suck with cudaminer at the moment because the CPU won't keep up.

[69charger]

Would a scrypt-jane version of cudaminer that utilizes SLI make sense? (speaking as total noob who has no idea what that involves but makes sense to my noob brain) 

[trell0z]

Heh ok, can't mine with that overclock! Just got myself an GTX 780 which is running nicely at 1250mhz core and currently 1600mhz memory, skynet bios etcetc. Discovered what you did earlier, power draw is off the charts hahah. It wants more even at 125% TDP and that's when the 100% is boosted to 300W+ on this bios >_> Did give me 555k/hash+ though! xD Will have to tweak it a bit 

[Snard]

Just compiled the git version to enable scrypt-jane.  I have been reading others speeds and see everyone post their speeds. When I ran it and started poking around I saw my khash as high as 18.33 khash/s and am wondering if what I am seeing is correct or actually working correctly.

Command line is: cudaminer-jane.exe -a scrypt-jane -C 0 -o http://127.0.0.1:44444 -u x -p x -l K7x32 -m 1

Code:

D:\>cudaminer-jane.exe -a scrypt-jane -C 0 -o http://127.0.0.1:44444 -u user -p x -l K7x32 -m 1

jeez my 660 ti PE with 2gb is only getting .95 with the scrypt-jane compiled by the kind guy a page back (Thanks btw)

I let it autotune and it came out to 9x1. Are yall using cpu as well> cuz I put -H 2 in my config

The performance isn't as good on Windows. My 780 only gets 1.9 kH/s. I'm probably going to install Linux on another drive this weekend.

use small launch configs, like K7x1 or K14x1 - even better let it autotune.

K7x32 would use way too much RAM. Not sure why you weren't notified that the memory is not sufficient.
Maybe some integer overflow... I need to fix that.
