# GPU Mining

## Nvidia/CUDA

Currently, the best option is Protovist's patch of ccminer on Ubuntu.

Instructions:

* Ubuntu 16.04 is known to work.
* Install the Zen Protocol wallet.
* Obtain the exact versions of CUDA (9.2.11-1) and openssl (1.1.1-pre8) needed:

```
sudo apt-key adv --fetch-keys http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1604/x86_64/7fa2af80.pub
sudo apt update
sudo apt dist-upgrade
sudo apt install build-essential automake
wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1604/x86_64/cuda-repo-ubuntu1604_9.2.88-1_amd64.deb
sudo dpkg -i cuda-repo-ubuntu1604_9.2.88-1_amd64.deb
sudo apt install libcurl4-openssl-dev 
sudo apt-get update
sudo apt-get install cuda
wget https://www.openssl.org/source/openssl-1.1.1-pre8.tar.gz
tar zxf openssl-1.1.1-pre8.tar.gz
cd openssl-1.1.1-pre8/
./config
make -j8
sudo make install
cd ..

```

* Get the right version of ccminer:

```
git clone https://github.com/protovist/ccminer.git
cd ccminer
git checkout zenprotocol
./build.sh
```

* Run the Zen Protocol client and create or import an account.
* Run ccminer, pointing it to the Zen Protocol client, like this:

```
./ccminer -a zenprotocol -o 127.0.0.1:11567
```

For a pool, change `127.0.0.1:11567` to the pool address.

## AMD

Proper AMD mining support is still in development. Right now you need to compile your own Zen Protocol node.

Instructions:

* Checkout or download the cgminer branch at [https://gitlab.com/zenprotocol/zenprotocol/tree/cgminer ](https://gitlab.com/zenprotocol/zenprotocol/tree/cgminer)
* Follow the instructions for building the Zen Protocol node.
* Get a patched cgminer from <https://github.com/A-Manning/cgminer_zp>
* Compile cgminer
* Run cgminer as follows:

```
cgminer --keccak -o http://127.0.0.1:11567
```
