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

[cbuchner1]

So, weird story...
I will stop mining with this executable (I'm not saying that there is a malicious function hidden since I have no proof)

hmm, I have not use any third party binaries lately and nevertheless I got the message from the yac.coinmine.pl pool saying that my account was locked. I don't think any malware triggered this.

Yesterday I was wondering why I had so little free space on my system SSD then I found out about the 12 GB bitcoin blockchain...

yeah, that's why I put 64 GB SSDs into my mining rigs. Anything smaller won't hold many block chains. The SanDisk SSDs are quite cheap and seem to be reliable.

did you upgrade to the new version of the wallet ? I read that it should be done otherwise it will stop to work

Can you guys help me out getting started with the YAC mining? I've downloaded the compiled file, but have no idea how you set it up.
Okies, got it set up. Now to find the settings for my Gtx 680...

T kernel in Windows on my Titan is very unstable during autotune unfortunately anything that allocates more then 3GB of VRAM just crashes Cudaminer outright. Not sure what direct limitation is causing this but this is a consistent observation with several hours of manual configurations.

1. Any idea why there would be this limitation in the T kernel for Scrypt-Jane? If I set to autotune Cudaminer instantly takes up 5.5GB of VRAM but once it begins testing any config that would result in > 3GB to be allocated the autotune crashes out. Any manual settings to allocate more then 3GB falls under the same issue.

2. Why do you think the T kernel favors T64x1\1, T64x2\2, T64x3\3, T64x4\4 so heavily if it only allocates ~2.4GB of memory? I can take this as high as ~T75x#\# before reaching that 3GB allocation limit, but the hash rates are roughly half of the T64#\# configs? This seems to be counter intuitive to the "More memory allocation is better." thought process.

3. The K kernel similarly has a 3GB limit on the Titan but actually allows allocation in the ranges of ~K80x#\#, Commit 92 showed higher hasrates ~7% using K21x1 -C 1 over T16x1 which was consistently the best T kernel autotune?

4. Do you feel this 3GB limit may vanish using a Linux build due to better VRAM allocation?

I understand that you may not be able to address these issue directly via code changes (if it is determined to need a change here), mostly speculation and curiosity at this point. Thanks in advanced!

After a quick search it seems that Titans tend to have issues with memory allocation. Allocating more than 3 GB could lead to all kinds of issues (missing textures in games, crashes, significant memory performance drops, etc). It's almost as if it had 2 x 3 GB ram, but it's a single GPU card..

I tried the Nvidia kernel on Vertcoin, and I'm seeing about a 11 % increase with hash rates up to 245kH from 220kH on my 780.

Only strange thing is that Z12x20 seems to be the sweet spot, I tried the recommended Z12x24 config and was getting around 190 kH (worse than previous).

Z12x24 definitely performs better with standard scrypt coins like Doge, Litecoin, etc though.

In case someone missed it (because I edited my post not knowing that page 146 was under all the other page numbers:
This was all tested on hashcows, same seems true for wemineltc.
Getting ~525khash/s with settings: -l Z12x24 on latest commit x64.
Getting ~432khash/s with settings: -l T12x24 on 12-18-2013 x64.
I'd definately say the nVidia guy did a good job
Using -i 0 on the latest commit barely changes anything, max profit of 10khash/s; Using -H 0 or 1 severely damages hashrates.

As for the kernels, I'd say use different kernels for everything and create prefixes like TS12x24 for scrypt and TJ9x2\4 for script-jane.

Sounds great, working on getting myself a Bitcoin wallet...

Interesting, the way I got my wallet set up at the moment doesn't need that 12gb blockchain?
It only downloads the part that is my related with my bitcoins, or so it says...

Oh wow...that explains allot. Where is this kept? I wanna move it to my HDD.

Is there a way to change the directory where the wallet puts the block chains?

With Litecoin and YACoin client it can be done by adding -datadir=C:\Whatever to your command line/shortcut

The same command works for the Bitcoin QT client as well.

Using -i 0 on the latest commit barely changes anything, max profit of 10khash/s; Using -H 0 or 1 severely damages hashrates.

The -i switch doesn't have much effect if you're not using your GPU much, but for example if you're gaming you might as well just stop mining.

As for the kernels, I'd say use different kernels for everything and create prefixes like TS12x24 for scrypt and TJ9x2\4 for script-jane.

I have a fairly neat system for all the different .bat files ([algo][coin][pool]setup.bat, which looks something like: [SJ][YAC][yac.m-s-t.org]K10x18 L3 i0 H2 s300.bat) but even then my cudaMiner compile folders are starting to look exhausting

[epicoverclock]

why am i only getting 200 khash with my Gigabyte GTX 570 Super overclock (GV-N570SO-13I)? other people have reported 260 khash with the exact same gpu. my bat file: cudaminer.exe -C 2 -i 0 -o stratum+tcp://fast-pool.com:3333 -O *workername*:*workerpass*

Tried -C 0, but it gives me even less (180)]

You could just use MultiBit, which doesn't store the blockchain locally. In the long term, this will be the only feasible way for most people to use Bitcoin anyway.

I like watching youtube videos, also 2d games like Terraria run pretty good with -i 1 (default).

[EndymioN666]

30 minutes after launching the new commit 111, my yacoin account was auto-locked because of too many attempts of connection.

It seems weird. Someone else have this problem ?

Maybe someone is trying to hack accounts over there by brute forcing passwords. Or some script malfunctioned and triggered false alarms.

Actually the same happened to me, started experimenting with 111 and my acc was auto-locked -.-

I have the exact same card as you do.

Try this:

Interactive:
C:\x86\cudaminer.exe -H 1 -d 0 -i 1 -l auto -C 1 -m 1
200 - 250khash/s

This means your pc stays a bit responsive

And this for full load:
C:\x86\cudaminer.exe -H 1 -d 0 -i 0 -l F30x8 -C 1 -m 1
270khash/s

Edit: oh and use the 2013-12-10 version of cuda miner, because the 2013-12-18 version makes your gpu run quite hot (90-95 degrees C)

Would this be in the debug console within the bitcoin wallet?

It's supposed to be a command line option
coinwallet.exe -datadir=<dir>

Only tested it with YAC but it crashes the wallet.
