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

[jayeeyee]

Sorry, I'm a GUI noob.  How do I use this, any setup instructions? cmd line settings? flags?  I have a 670GTX card.

The command line settings are explained in the README.txt file. README as in read me.

If you are not familiar with the command prompt (CMD.exe), I suggest you wait until my miner becomes included in some GUI based mining kits. It shouldn't take long before such solutions will be available.

The 320.00 beta driver really made my GTX 660Ti slightly faster. With my current experimental cudaminer version (unreleased) I reach 168-171 kHash/s (slightly varying over time). Before the driver update it was around 160.

cudaminer do not work on triplemining.com???

cudaMiner is for scrypt based mining only. bitcoin is sha256d

Find my setting for gtx 670, 174kh/s
Flags/setting can be found from.

Link goes to gid 1 by default, Would you change it to 2 because it better organized?

@yakka: In the README there is some documentation on what arguments do. There's even an example...

curious, what are you running your 660 ti at, stock? also what clocks etc. if you are stock settings, model? I ask because without the beta driver and your unrelease optimized version (i am using the 4/22) i am getting +180 with my msi 660 ti pe at stock no OC. i am using flags -i 0 -C 2 -l 42x7

thx

I have an EVGA 660Ti "SC" (Superclocked, meaning a slight factory overclock), it has 3 GB memory.

Right now it runs at core clock 1097.4, memory clock 1502.3. TDP around 99.6% doing hashing.

Interestingly, the GPU load seems to oscillate between 85 and 99%. which is where I might be losing
some performance.

Maybe it's a TDP or temperature issue and the GPU clocks down or idles when needed?

Mine currently runs fastest with-i 0  -l 70x2 -C 2

There is also a principal issue with autotune, as the card may dynamically adjust its clock speed to meet TDP requirements, therefore interfering with the accuracy of the measurements. Argh.

hmmm... my clock's are almost identical to yours but I do not see much if any fluctuation of load, just flat lined pegged out i guess that is the difference.

i see no issue with temps on my card, fan is not working hard ~40% and temp steady 62c power consumption ~80% all numbers flat and steady without fluctuation.

curious if anyone has any success with OC... i have tried to OC my card and i get good performance increases for gaming (stable OC as far as temps and such) but oddly my hashing dips slightly... weird

EDIT

Mine currently runs fastest with-i 0  -l 70x2 -C 2

I have also used this setting and get almost 180 but the 42x7 pushed me over

Christian,
 I'm looking @ htop and not sure i completely understand it:

Code:

why is it 98% CPU utilization?

[BrewCrewFan]

Arg finally got this to work. Its funny when you do read the read me, tells you all the flags and stuff... but never tells you how to modify. Finally I made a shortcut and then added all the info I needed to into it and walla... its working 2x faster with heck less lag as cgminer did. Now to find some good settings for the 660/540/250.

Huh, were did my response go?  Well, let's type it again:

I also noticed the effect that on Linux, one thread will continually eat 100% on a single CPU core. I believe Linux defines 100% CPU utilization as full load on one core. i.e. a 6 core CPU can go up to 100%. This effect does not occur on windows.

As an example: My desktop PC is mining on 4 GPUs at 500kHash and is currently using 30-40% CPU for cudaMiner (Phenom II 1055T CPU, not the fastest one really). I believe most of this load is actually caused by submitting input data to the GPU (SHA-256) and also hashing GPU results again before validating them against the difficulty target.

I suspect on Linux there is one thread that continually pegs the CPU - either within the CUDA API, or possibly the usleep() API call that does some kind of busy wait when sleeping for sub-millisecond time intervals.

If someone knows what is going on, please let me know.

What are the best tools to overclock Kepler based GPUs? that MSI AfterBurner tool sucks

actually you are right - it does say the process is sleeping... but taking 100% CPU %)

I like EVGA Precision X personally.

[Misiolap]

@dbabo
Try this:
in salsa_kernel.cu find line:

Code:

cudaSetDeviceFlags(cudaDeviceScheduleYield);

and change it to

Code:

cudaSetDeviceFlags(cudaDeviceScheduleBlockingSync);

On my setup it doesn't help much, as most cpu time is spent in sha256_transformx4 function, but it may help on your setup.

I've used EVGA Precision but I liked NvidiaInspector more.  It seemed to have more/better control for my cards.  I have 2 gtx560se's and Precision would only adjust one of them and leave the other at stock.  NvidiaInspector lets you set each cards speeds, fan, and voltage separately.

Try them both.
