Help Getting GPU And Software To Work On Ubuntu

danmartinj · 01-26-2018, 08:50 PM

Hello,

I have been battling the Nvidia Quadro K2000 GPU on Ubuntu for several days now. Basically, I am trying to get ccminer to work with dual Quadro K2000 GPUs. I have tried two separate machines and I am starting to think now that those GPUs are just too old to work.

I dowloaded and successfully installed the linux driver from the nvidia website. If I run nvidia-smi I get:

Code:

I installed different versions of the cuda SDK toolkit and it does install but I think this is where the problem lies.

When I install ccminer and try to run it I get:

Code:

 2 miner threads started, using 'cryptonight' algorithm.
 Stratum difficulty set to 20000 (20)
 GPU #0: Quadro K2000, 1883 MB available, 2 SMX
 GPU #0: 64 threads (6) with 8 blocks
 GPU #1: Quadro K2000, 1972 MB available, 2 SMX
 GPU #1: 64 threads (6) with 8 blocks
 GPU #0: invalid device function cryptonight_extra_cpu_prepare line 217
 GPU #1: scanhash_cryptonight:78 driver shutting down
 GPU #1: driver shutting down cryptonight_extra_cpu_init line 205

Basically, I would prefer to use the crypto-miner forums but they basically never reply back and I have had such great luck with linuxquestions forum in the past I was hoping someone here might have some advice or suggestions for me. Like I said I feel the problem is either with cuda and or the GPUs just being too old. Any help would be great appreciated.

The Quatro K2000M requires legacy 304.xx drivers, not the latest and greatest 387.26 which is for latest and greatest Nvidia graphics devices.

Launchpad.net is where most Ubuntu folks get pre-compiled .deb drivers, after adding the repository and installing through package manager(s). Look around this page to pick a mirror close to you if you would like to install this way.

Also check your version of Ubuntu default repositories.

Sorry
That was Debian site that said 304
According to Nvidia site your card needs 384.111
Select Linux as OS in the search

Brains,

Thanks for your time. I have actually already tried that driver version. I actually just removed the current driver and just now installed and verified the 384.111 driver is in use and I am getting the below output when running ccminer:

GPU #1: invalid device function
GPU #0: invalid device function
GPU #1: invalid device function

And it just loops in place. This is a tricky problem as from what I read older Nvidia GPUs should be able to operate using ccminer however nothing I have done has worked after trying several different Nvidia and Cuda drivers. Something seems to always fail.

Perhaps you have any other ideas? Thanks again for your help.

Check whether you have the correct version of ccminer. Yours is a compute 3.0 card: http://cryptomining-blog.com/4950-wh...ur-nvidia-gpu/

Thanks for your help everyone. Just to let you know it took me a few days to figure it out as "in my opinion the documentation was vey weak" there was an option in the Make file that allowed you to modify manually for me to get it to work. The option was nvcc_ARCH. Once I did this I was finally able to get to work. However, in my opinion it seems a bit buggy but it is working last time I checked. Thanks for everyones time and help.
