Ethminer: Unable to select OpenCL devices with command line arguments

Created on 9 Sep 2017  Â·  19Comments  Â·  Source: ethereum-mining/ethminer

When I go to select what OpenCL devices I want by setting them up in a bash file, I'm not able to select the Open-CL devices I would like to run, it auto defaults to my first GPU.

ethminer.exe -G -F http://<MINING_POOL>/<WALLET>/<RIG_NAME>/<EMAIL> --opencl-devices 4,5,6,7,8,9,10

However when I do this using the Cuda command it works exactly as I want

ethminer.exe -U -F http://<MINING_POOL>/<WALLET>/<RIG_NAME>/<EMAIL> --cuda-devices 0,1,2,3

I have 4 1060s, and 7 RX470s on my rig, I'm trying to setup ethminer so that I can mine Cuda with my NVidia GPUs and OpenCL with my RX470s.

I've also tried specifying this with -X and --cuda-opencl but both seem to just default to my first NVidia card.

I'm running on Windows 10x64 and using the AMD Blockchain Beta Driver. I am able to see all my cards correct with --device-list which is where I'm getting my device numbers from.

Any help would be appreciated.

Thanks

I figured it out thanks to this string of comments. I screwed this up when I tried it first. I had to change the platform, not the device. Thanks for the clearer information. When I check for devices (just to test on this machine):
ethminer -G --list-devices
I get:

Listing OpenCL devices.

        CL_DEVICE_MAX_MEM_ALLOC_SIZE: 1073741824
        CL_DEVICE_MAX_WORK_GROUP_SIZE: 1024

So then I try to target the GeForce:
ethminer -M -G --opencl-devices 1 --opencl-platform 1 --opencl-device 0
And then it starts in on the GeForce, where everything else would go on the integrated Intel device:

  i  08:41:00|main      Found suitable OpenCL device [ GeForce GTX 770 ] with 4294967296  bytes of GPU memory

I think what I'm doing is specifying to use a single device with --opencl-devices 1 then specifying the platform --opencl-platform 1 then the GeForce card --opencl-device 0.

use --opencl-platform 1 or --opencl-platform 2 in the opencl start to mine with AMD cards.
-X currently only work in stratum mode. (there is a PR which fixes that)

307 tries to make the importance of also specifing --opencl-platform clearer

I have a similar issue. I have two 1070 cards, where I want to mine using the second one. When trying to just use one of them by using the --cuda-devices 1 command, both are still used.

I think technically all you need there is --opencl-platform 1, and then it will grab the only device at that platform

Looking at the code around https://github.com/ethereum-mining/ethminer/blob/6f28ec56a8075b69406931bfea2a1262958ef019/libethash-cl/CLMiner.cpp#L325 it doesn't appear to do anything with the device number. It simply returns the first device that has enough memory for the DAG. @smurfy ?

Just adding another datapoint. I see the same thing as @contentfree
Also getting ~3 MH/s since I assume it's not using the right graphics card.

Macbookpro 2016 w/ rx580 that's connected via an egpu. It gets ~22MH/s in windows no problem.

Its quite strange, that it shows intel + amd on the same platform. On linux+windows they are two different platforms.

You can try --opencl-platform 1, but i'm not sure this will work.
You also can try disabling the onboard intel card :)

smurfy picture smurfy on 24 Dec 2017

Forcing the switch to the discrete card (eg, using gfxCardStatus) doesn't
make a difference.
Using --opencl-platform 1 causes ethminer to exit with status 1.

same issue. on MacBook Pro, always choose 530 graphic device.

maweis1981 picture maweis1981 on 30 Jan 2018

I can confirm that I'm experiencing the same issue with Ubuntu 16 and legacy OpenCL (meaning, I had to compile the AMDGPU-PRO drivers the --opencl=legacy flag). I have two R9 290x 's and it's only mining on one (the first one) and nothing else.

Using Ubuntu 16.04.3 LTS ethminer version 0.14.0.dev3+git.83693003 build

My system has two 1070ti cards and one RX580 card. ethminer does mine, however only with the 1070ti cards. The system can see the 1070tis and the 580 but it only mines with the 1070tis...
