violetminer

A CPU and NVIDIA miner for TurtleCoin / Chukwa / ChukwaV2 / WrkzCoin.

GPUs older than 800 series (8xx) are unfortunately not supported, as Cuda 11.1 does not support these ( https://en.wikipedia.org/wiki/GeForce_700_series#Discontinued_support)

Download

Go here to download the latest release.

If you prefer to compile yourself, read on. This can result in increased hashrates in some cases.

Setup / Usage

We suggest you follow the guide here to setup your miner.

Algorithms Supported

TurtleCoin (ChukwaV2) - choose turtlecoin or chukwa_v2
WrkzCoin - choose wrkzcoin or chukwa_wrkz
Chukwa - choose chukwa

Notes

Supports AVX-512, AVX-2, SSE4.1, SSSE3, SSE2 and NEON optimizations.
Supports NVIDIA GPUs.
You can set a priority to a pool to determine which ones are tried first. A smaller priority number means we will connect to it first. 0 = highest priority. If we are not connected to the highest priority pool, we will continuously retry connecting to higher priority pools.
There is no dev fee.
Supports xmrig-proxy - Make sure to enable "niceHash": true in your pool config.
Getting an error about a missing MSVCP140_1.dll or vcrruntime140_1.dll? You are missing the Visual C++ 2019 Redistributable. You can find that here or Direct download link (x64)

Configuring

There are a couple of ways to configure the miner.

Just start it, and walk throught the guided setup. Upon completion, the config will be written to config.json for modification if desired.
Use command line options. Use violetminer --help to list them all. It is not recommended to use command line options, as they are less configurable than the config. Only --algorithm, --pool, and --username are mandatory.

For example:

./violetminer --algorithm turtlecoin --pool trtl.pool.mine2gether.com:2225 --username TRTLv2Fyavy8CXG8BPEbNeCHFZ1fuDCYCZ3vW5H5LXN4K2M2MHUpTENip9bbavpHvvPwb4NDkBWrNgURAd5DB38FHXWZyoBh4wW

Copy the below config to config.json and modify to your purposes.

Disabling CPU/GPU/Specific Cards

If you want to disable CPU mining, either set enabled to false in the cpu section, or start the miner with the --disableCPU flag.
If you want to disable Nvidia mining, either set enabled to false for each card in the nvidia devices section, or start the miner with the --disableNVIDIA flag.
If you want to disable a specific Nvidia or AMD card, just set enabled to false in the nvidia devices section for the appropriate card.

Note that changing the name field does not do anything. It is only there to help you identify which device has which id. It's highly recommended that you don't change the name or id fields, or you may end up with quite a confusing result.

You can always delete your config file, and let the program regenerate it, if you mess up.

GPU Configuration

Intensity

In addition to enabling and disabling specific cards, you can also configure how many threads and how much memory they use.
This is done by altering the intensity value in the config.
A value of 100 for intensity means the maximum threads and memory will be used.
A value of 0 for intensity means no threads and memory will be used.
Lower intensities don't neccessarily mean lower hashrate.

Desktop Lag

The desktopLag value determines how long we will sleep between kernel launches.
The default value of 100 means there are no sleeps between launches.
This is appropriate for most setups, where you are just mining.
However, if you are mining on your personal PC, and your desktop is quite laggy while mining, you can use this setting to decrease the lags.
A value of 100 means maximum desktop lag, a value of 0 means minimum desktop lag.
You can see how long we will sleep between launches printed at startup.
A lower value of desktop lag means less hashrate, because we launch the hasher kernel less.

CPU Optimization method

By default, the program will automatically choose the optimization method to use.

In some cases, you may find you get better performance by manually specifying the optimization method to use.

You can, if desired, use a different optimization method, or disable optimizations altogether.

Note that you can only use optimizations that your hardware has support for - these are printed at startup.

Simply set the desired value in the optimizationMethod config field.

Available optimizations for each platform are as follows:

x86_64 (64 bit Intel/AMD Windows/Mac/Linux)

AVX-512
AVX-2
SSE4.1
SSSE3
SSE2
None
Auto

ARMv8

Note: On ARMv8, Auto uses no optimizations. From my testing, the NEON implementation actually performs worse than the reference implementation. You may want to experiment with toggling between NEON and None if you are on an ARM machine.

NEON
None
Auto

Anything else

Compiling

Disabling NVIDIA support

Run cmake with the -DENABLE_NVIDIA=OFF flag: cmake -DENABLE_NVIDIA=OFF ..

Windows

Download and install CUDA from here: https://developer.nvidia.com/cuda-downloads (This step is only if you want Nvidia support.)
Download the Build Tools for Visual Studio 2019 Installer.
When it opens up select C++ build tools, it automatically selects the needed parts.
From the start menu, open 'x64 Native Tools Command Prompt for VS 2019'.
cd C:/ (Or your directory of choice)
git clone https://github.com/turtlecoin/violetminer
cd violetminer
git submodule update --init --recursive
mkdir build
cd build
cmake -G "Visual Studio 16 2019" -A x64 ..
MSBuild violetminer.sln /p:Configuration=Release /m

Linux

It's recommended to use Clang to compile. It gets better CPU hashrate for many people.
If you're on ARM however, GCC gets slightly better hashrate.
You will need to install CUDA if you want Nvidia support, which is somewhat out of the scope of this document.
You can find the CUDA binaries for linux here: https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64

Ubuntu, using Clang

sudo add-apt-repository ppa:ubuntu-toolchain-r/test -y
wget -O - https://apt.llvm.org/llvm-snapshot.gpg.key | sudo apt-key add -

You need to modify the below command for your version of ubuntu - see https://apt.llvm.org/

Ubuntu 14.04 (Trusty)

sudo add-apt-repository "deb https://apt.llvm.org/trusty/ llvm-toolchain-trusty 6.0 main"

Ubuntu 16.04 (Xenial)

sudo add-apt-repository "deb https://apt.llvm.org/xenial/ llvm-toolchain-xenial 6.0 main"

Ubuntu 18.04 (Bionic)

sudo add-apt-repository "deb https://apt.llvm.org/bionic/ llvm-toolchain-bionic 6.0 main"
sudo apt-get update
sudo apt-get install aptitude -y
sudo aptitude install -y -o Aptitude::ProblemResolver::SolutionCost='100*canceled-actions,200*removals' build-essential clang-6.0 libstdc++-7-dev git python-pip libssl-dev
sudo pip install cmake
export CC=clang-6.0
export CXX=clang++-6.0
git clone https://github.com/turtlecoin/violetminer
cd violetminer
git submodule update --init --recursive
mkdir build
cd build
cmake ..
make

Ubuntu, using GCC

sudo add-apt-repository ppa:ubuntu-toolchain-r/test -y
sudo apt-get update
sudo apt-get install aptitude -y
sudo aptitude install -y build-essential g++-8 gcc-8 git python-pip libssl-dev
sudo pip install cmake
export CC=gcc-8
export CXX=g++-8
git clone https://github.com/turtlecoin/violetminer
cd violetminer
git submodule update --init --recursive
mkdir build
cd build
cmake ..
make

Generic Linux

Reminder to use clang if possible. Make sure to set CC and CXX to point to clang and clang++ as seen in the Ubuntu instructions.

git clone https://github.com/turtlecoin/violetminer
cd violetminer
git submodule update --init --recursive
mkdir build
cd build
cmake ..
make

Android with Termux

pkg install cmake clang git (Enter y to confirm the install)
git clone https://github.com/turtlecoin/violetminer
cd violetminer
git submodule update --init --recursive
mkdir build
cd build
cmake -DENABLE_NVIDIA=OFF ..
make

Or, if you hate typing and just want something to copy paste, try this single command:

cd && rm -Rf violetminer && apt-get update && pkg update -y && pkg install cmake clang git -y && git clone https://github.com/turtlecoin/violetminer && mkdir violetminer/build && cd violetminer/ && git submodule update --init --recursive && cd build/ && cmake -DENABLE_NVIDIA=OFF .. && make

Android Cross Compile

Using this toolchain

ANDROID_ABI can be

armeabi-v7a
arm64-v8a
x86
x86_64

Set this depending on the architecture of the phone you want to run it on.

git clone https://github.com/turtlecoin/violetminer
cd violetminer
git submodule update --init --recursive
mkdir build
cd build
cmake -DCMAKE_TOOLCHAIN_FILE="${HOME}/Android/sdk/android-ndk-r20/build/cmake/android.toolchain.cmake" -DANDROID_ABI=arm64-v8a -DANDROID_CROSS_COMPILE=ON ..
make
