ethminer-0.9.41-genoil-1.1

[BitMinerN8]

It's kind of weird that that worked. Better for you to -DCOMPUTE=0 and remove Compute 6.1 from Cmakelists.txt in libethash-cuda folder.

I stand corrected, it did not work with 1.1.1, my mining script was still calling -G
Also, I looked all over and can't seem to find a Cmakelists.txt in libethash-cuda folder, should it be there after the cmake?
Thanks.

Remove the bits with '61' in them, or better, only leave 35 and 50 in.

hello,
its not working for me on gtx 1080
this is what the log says:

Code:

i 20:36:58|cudaminer0 Initialising miner…
Using device: GeForce GTX 1080 (Compute 6.1)
Cuda error in func ‘set_constants’ at line 128 : invalid device symbol.

is there something i can do to make this work?

Which zip have you downloaded from where? You need one of the 1.1.x zips from the 110 branch. But it won't be fast on Windows, I can tell you that.

alright, this seems to be my mistake.
i have now downloaded the ethminer-0.9.41-genoil-1.1.2.zip from branch 110 as you said.

it is working. The Hashrate on the gtx 1080 is about 4.19 MH/s. Is this a rate you expected or is still something wrong?

Thanks in advance

You need  Linux if you want to mine eth now, later there will be a driver for win7/8 and in July its possible that it will be avalible on win 10

[smaxz]

how many mh/s is linux netting with what kind of power draw?

[vaulter]

how many mh/s is linux netting with what kind of power draw?

23.7 mhs on 1080 - at 140w - but I need to test with power limit lowered - I think its 99% that it can hash the same at 100w level - will report tomorrow
its 26.7 mhs for 1070 - so there maybe a fix for 1080 - need to investigate

[merc84]

How much did the 1070 cost?

This worked. I'm now doing this per rig with just the flavor of cards in it.
Much thanks!

Ok, I didn't see anything that stood out in the mass of messages going across the screen when trying to install on Ubuntu.  But something must have gone haywire.  I get the following when I try to run the executable:

CUDA error in func 'getNumDevices' at line 112 : no CUDA-capable device is detected.
terminate called after throwing an instance of 'std::runtime_error'
  what():  no CUDA-capable device is detected
Aborted (core dumped)


Any ideas where I missed something?  I used the 110 branch.  This machine has the 750ti cards in it, but appears it isn't detecting them?  Right now I only have one card connected.

What options did you use on your cmake?
Example:

Code:

cmake -DBUNDLE=cudaminer ..

[Longsnowsm]

My options in cmake are:

cmake -DBUNDLE=cudaminer -DCOMPUTE=30 ..

And I also tried:
cmake -DBUNDLE=cudaminer -DCOMPUTE=52 ..

[BitMinerN8]

My options in cmake are:

cmake -DBUNDLE=cudaminer -DCOMPUTE=30 ..

And I also tried:
cmake -DBUNDLE=cudaminer -DCOMPUTE=52 ..

Well as a test, had the 108 (current default git) been working for you? I had an issue with 110 (compiles as 1.1.2) crashing, Genoil advised me to go into this folder ~/ccp-ethereum/libethash-cuda and modify the CMakeLists.txt to remove references to 61.
Example, mine now looks like:

Code:

set(CUDA_NVCC_FLAGS ${CUDA_NVCC_FLAGS};-gencode arch=compute_35,code=sm_35;-gencode arch=compute_50,code=sm_50)

But if you only have 750ti, you should be able to just use:

Code:

set(CUDA_NVCC_FLAGS ${CUDA_NVCC_FLAGS};-gencode arch=compute_50,code=sm_50)

Then try your cmake, with just:

Code:

cmake -DBUNDLE=cudaminer ..

I don't think the other options will be needed anymore, I didn't need them since that is what I edited out.

If none of that works and I'm not helping at all, can you try starting with the -G and see if opencl is working? At least that way you know the drivers are at least loaded and seen. Maybe we can go from there. Also, what flavor of Ubuntu? I'm using 14.04 as I could not get it working on 16.04.

Where the download link  for windows version? i want to try it

@BitminerN8 Thanks for the input.  I had seen the note from Geniol to you and I had removed those references in that file.  Still had the same issue so I suspected drivers.  Made the mistake of trying to install the .run file then couldn't get X Win to let me log back in with Ubuntu.  Found some references to messed up perms on .XAuthority and a few other things.  Nothing worked. 

So back to the drawing board, I just blew the box away and starting from scratch.  Hopefully I can get some working drivers and then try to install Genoil's miner again...  I swear, sometimes you cannot win for losing... It has been a nonstop battle with this rig... It is a new build and I did not have it running on 1.0.8.

Thanks again for the feedback.

No worries, my linux skills are not that great, but I try. These are the steps I have used on my Ubuntu 14.04 rigs. (I think I got from a readme or faq from a mining pool) Feel free to try this it if it works for you great. Again, I'm no expert, just collect stuff that works for me.
From a fresh install:

Code:

wget http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1404/x86_64/cuda-repo-ubuntu1404_7.5-18_amd64.deb
sudo dpkg -i cuda-repo-ubuntu1404_7.5-18_amd64.deb
sudo apt-get -y install software-properties-common
sudo add-apt-repository -y ppa:ethereum/ethereum
sudo apt-get -y update && sudo apt-get -y install screen htop git cmake libcryptopp-dev libleveldb-dev libjsoncpp-dev libjson-rpc-cpp-dev libboost-all-dev libgmp-dev libreadline-dev libcurl4-gnutls-dev ocl-icd-libopencl1 opencl-headers mesa-common-dev libmicrohttpd-dev build-essential cuda

IIRC you need to reboot, then continue:
On the 110 branch or remove the -b 110 once it goes main.

Code:

git clone -b 110 https://github.com/Genoil/cpp-ethereum/ && cd cpp-ethereum && mkdir build && cd build

This is where you then need to edit ~/ccp-ethereum/libethash-cuda/CMakeLists.txt to remove references to 61.

Code:

nano ~/ccp-ethereum/libethash-cuda/CMakeLists.txt

And then compile.

Code:

cmake -DBUNDLE=cudaminer ..
make -j8

If it builds with no errors, the compiled ethminer will be in the ~/cpp-ethereum/build/ethminer folder. I just copy that to my home folder and run it from there. (cp ethminer ~ && cd ~)

Hope it works for you.
