So, because some blame me here is my full config

Windows 8.1 64
core I5
16gb ram
ATI 14.6

3 R9 290X in the computer (not oc)

Config that works :

Code:

gpuPlotGenerator.exe plots myaccountid 68847637 18500000 4096 256

9400 nonces minutes

gpuPlotGenerator.exe plots myaccountid 68847637 18500000 4096 128

14500 nonces minutes

gpuPlotGenerator.exe plots myaccountid 68847637 18500000 4096 64

14500 Nonces minutes

nobody is blaming you.. you have confirmed it working for 290x multiple times and thats great..

now we(me) are working on 280x.. all I am asking is dont reply to questions regarding 280x when you have a 290x card because they are not the same and its not helping at all.

I feel like we can let this go now?

Im interested in hearing if there are any other gpus working or is 290x the only card capable of gpu plotting?

Ok no pb, i' have an other computer with some 280x i'm going to try

Ok there is tested config for 280x:

Code:

gpuPlotGenerator.exe plots myaccount 68847637 18500000 4000 64

I'm getting arround 15k per minute. Great job. Thank you.

Mark.ti still here? seems like someone got it working on a 280x

Hi.im making a MV for teaching people how to mine BURST

[redsn0w]

Whit this command :

AMD Radeon HD 7640G  ( Internal dac 400Mhz )
OS win 8  4 GB di ram
Core  AMD A8-4500M apu 1.90 Ghz

Code:

gpuPlotGenerator.exe plots ADDRESS 1 10000 4096 64

This is the output :

Someone can re-post the GPU plotter download link? Is working fine also with nvidia kepler cards?

[alphateam]

Ok so,

Not working on my 280x too, just stop without error noticed

Try with other 7850 and 7870, and say not gpu found, try with cpu

hey guys i have tried to make a bat to run the gpu plotting (i have R9 290x) i downloaded the gpu plotter but when i run the bat i get not a valid win32 application. any ideas?

EDIT: now it just opens and closes instantly

Put "pause" on the end of the cmd line in the bat file to troubleshoot what is causing it.

Unfortunatly it doesn't work with my gtx 770, someone can post his configuration?

[bipben]

Hi everyone,

After many hours of setup I finally made it. I have a 1Tb generation in progress and 3x100Gb already finished.
I would like to test the V2 pool but I haven't any BURST for now. Could someone send me 1 BURST to test it please ? Here is my address : BURST-YA29-QCEW-QXC3-BKXDL.

Regarding the plot generation, I found an OpenCL implementation of Shabal (https://github.com/aznboy84/X15GPU/blob/master/kernel/shabal.cl) that could be used to make a GPU version of the generator. I will try to work on it when I have some free time.

Regards

Hi everyone,

As promised I have been working on a GPU plot generator on the last few days. I made a little program built on top of OpenCL, and it seems to work pretty well in CPU mode. Unfortunately, I can't test the GPU mode as it requires a very powerfull graphic card (with at least 46kB private memory per compute unit, because the algorithm needs at least 4096*64 static bytes to store an entire plot).

Here is a preview you can test for now :
gpuPlotGenerator-src-1.0.0.7z : https://mega.co.nz/#!bcF2yKKL!3Ud86GaibgvwBehoxkbO4UNdiBgsaixRx7ksHrgNbDI
gpuPlotGenerator-bin-win-x86-1.0.0.7z : https://mega.co.nz/#!HJsziTCK!UmAMoEHQ3z34R4RsXoIkYo9rYd4LnFtO_pw-R4KObJs

I will build another release in the end of the day with some minor improvements (threads per compute unit selection, output of OpenCL error codes, improvement of the Makefile to generate the distribution directly).
I will also try to figure out another mean to dispatch the work between the GPU threads to reduce the amount of private memory needed by the program.

For the windows people, you can use the binary version directly.
For the linux people, just download the source archive, make sure to modify the OpenCL library and lib path in the makefile (and maybe the executable name), and build the project via "make". To run the program, you need the "kernel" and the "plots" directories beside the executable.

The executable usage is : ./gpuPlotGenerator <address> <start nonce> <nonces> <stagger size>
The parameters are the same as the original plot generator, without the threads number.

If you find bugs or if you want some new features, let me now.

It's nice to see someone else working on this, since I seem to have failed in it.

Private memory is actually part of global on AMD cards, so storing it in private isn't any better than just using global for everything; it's local that needs to aimed for for the massive speedup. No AMD cards have more than 64KB local per workgroup, which makes storing it all in local impossible however.

I haven't tried your implementation yet, but on my own first attempt, I also used global on everything also, and the result was faster than the java plotter, but slower than dcct's c plotter. My 2nd attempt used a 32KB local buffer I rotated through for storing the currently being hashed stuff, however I couldn't figure out how to get it copied also to global fast enough, and the local -> global copy killed the performance.

You might be interested in those kernels here: https://bitcointalk.org/index.php?topic=731923.msg8695829#msg8695829

Thanks, I will look at your kernels to see if I can find a better solution.

Here is the new version. I reduced the amount of memory used from 40KB to about 1KB per unit. The only drawback is that it requires twice the global memory as before. I will search a mean to reduce this overhead later.
In CPU mode, it all goes pretty well (when no graphic card is detected).
The GPU mode is still kind of buggy on my graphic card (an old GeForce 9300M GS), don't know the exact reason yet. Sometimes it works, sometimes not. I will try to fix this issue tomorrow.

Here are the files :
gpuPlotGenerator-src-1.1.0.7z : https://mega.co.nz/#!iYFWAL5B!BvtmRQ5qGq4gGwjDglFNtDtNIX4LDaUvATBtClBdTlQ
gpuPlotGenerator-bin-win-x86-1.1.0.7z : https://mega.co.nz/#!aBVGBBQD!tBsRtb8VrHR12_anrFTrl41U0fPQu_OqFnxyi5nCyBY

For the linux users, the Makefile has a new target named "dist" that builds and copy/paste all the necessary files to the "bin" directory.

The executable usage is : ./gpuPlotGenerator <path> <address> <start nonce> <nonces> <stagger size> <threads>
<path> : the path to the plots directory
<threads> : number of parrallel threads for each work group

Found the "randomness" cause. NVIDIA is caching the kernel after the first build and rebuild it from time to time. By cleaning the cache, I can force the kernel build and speed up the debugging process.
I will notify you as soon as the crash cause is found and corrected.

Bad news guys. There is no actual "bug" in the implementation. Seems like the graphic card is beeing streesed too much by the shabal core, thus the driver is shutting down the kernel (there is a watch-dog timer for this purpose hard coded in the display driver to ensure that the display don't freeze too much). I will try to improve the whole algorithm and memory consumption to the needed graphic card power.

In the meantime, I found this thread (http://stackoverflow.com/questions/12259044/limitations-of-work-item-load-in-gpu-cuda-opencl) that speak about this particular issue. The available options are :
- If you have more than one graphic card, you can launch the plotter on the one that does not hold the display. There is still no option to select the graphic card in the plotter, but I will code it soon so that you can test it in a multi-GPU environment.
- You can try to turn-off the watchdog timer by following the provided link, but be CAREFUL, you may experience terrible display lags, or even full black screens until the plotter process finishes its work.

You don't need to improve it to avoid this issue, just split it. One kernel for first half, one kernel for second half.

What do you mean by splitting it ?
If you mean "splitting the nonces chunks" : I don't think that two kernel instances, one for each half staggerSize, will resolve the stressness problem. The actual algorithm break my NVIDIA Quadro 4000 in the middle of the P application. Moreover it will need twice more memory to run, both on GPU and CPU side.
If you mean "splitting the shabal from the nonces generation" : I don't see how for now.

EDIT: now it just opens and closes instantly

Open a prompt window , use the comand cd  directory_of_the_gpuPlotGenerator , and after use this command :

Code:

gpuPlotGenerator.exe plots ADDRESS 1 10000 4096 64

Ps :  64 is the number of the  thread .

The -54 error is "CL_INVALID_WORK_GROUP_SIZE". Maybe 64 threads is too high for your GPU. Try a lower number like 32.

Seems like only the AMD 290X is the only card that successfully runs the gpu plotter.
