Quick Start[CUDA version]

If you're familiar with using a terminal, the following commands can help you get started quickly.

apt update && apt upgrade -y  # Update system packages
apt install git cmake make sudo -y  # Install necessary packages for building
git clone https://github.com/shanhaicoder/XENGPUMiner.git  # Clone the repository
cd XENGPUMiner  # Navigate to the project directory
chmod +x build.sh  # Make the build script executable
sudo apt install ocl-icd-opencl-dev  # Install OpenCL development package
./build.sh  # Run the build script
pip install -U -r requirements.txt  # Install the required Python packages
chmod +x miner.sh
./miner.sh

Please note that this Quick Start assumes you are on a Debian-based system (like Ubuntu) and have some knowledge of Linux command line, and it is only intended to serve as a basic guide to get the software running quickly. For more detailed information on building and configuring the miner, refer to the relevant sections of this document.

Building

Preliminary Setup for Beginners

If you are unfamiliar with the building process or are encountering difficulties, you can run the following commands to install the necessary dependencies. If you are familiar with this process, feel free to adapt according to your preferences.

apt update && apt upgrade -y
apt install git cmake make sudo -y

Remember, these commands are for Debian-based systems like Ubuntu. Please adapt them according to your operating system if needed.

Note: The sudo command is generally installed by default on most Linux distributions, but it is included in the command just in case it is not present.

Building from Source

To build from the source, follow the steps below. Please make sure you have git, cmake, and make installed on your system. If not, you can install them using your system's package manager.

Now, proceed with the following steps to clone the repository and build the project:

git clone https://github.com/shanhaicoder/XENGPUMiner.git 
cd XENGPUMiner
chmod +x build.sh

OpenCL Installation

To enable OpenCL support, you need to install the OpenCL development package. On Debian-based systems like Ubuntu, you can run the following command:

sudo apt install ocl-icd-opencl-dev

Please adapt the command according to your operating system if it's not a Debian-based system.

CUDA Installation

For CUDA support, you need to have both the NVIDIA driver and the CUDA Toolkit installed. You can refer to the official CUDA Toolkit Archive to download and install the CUDA Toolkit suitable for your system.

Before installing the CUDA Toolkit, run the nvidia-smi command to check the existing driver installation and verify the compatibility of your driver version with the CUDA Toolkit version you plan to install. If you need to update your NVIDIA driver, please refer to the official NVIDIA Driver Download page.

Here's a general guideline for installing CUDA:

1. Check your NVIDIA driver installation and version with nvidia-smi.
2. Refer to the official CUDA Toolkit Archive and download a compatible version.
3. Follow the instructions provided in the download page to install the CUDA Toolkit.

Execute build.sh

Before running the build script, you can specify the CUDA architecture you are targeting by using the -cuda_arch flag followed by your CUDA architecture version. For example, if you are targeting CUDA architecture 6.1, you would run:

./build.sh -cuda_arch sm_61

When building the project, it is crucial to specify the correct cuda_arch value to optimize the performance of your application. This value should correspond to the Compute Capability of your Nvidia GPU.

You can refer to NVIDIA CUDA GPUs to find the correct Compute Capability value for your GPU model. Or this is beter: matching-sm-architectures-arch-and-gencode-for-various-nvidia-cards, make sure you have a higher version CUDA toolkit installed. Once you have identified the right value, specify it with the -cuda_arch flag when running the build script, as shown below:

./build.sh -cuda_arch sm_86  # Example: For a GPU with Compute Capability 8.6

If you omit the -cuda_arch flag, the build script will default to using sm_75. While the script may still run without specifying cuda_arch, defining it correctly ensures that you are utilizing your GPU to its full potential.

Usage

Preliminary Setup:

Install the necessary Python packages before running the CPU version for the first time:

pip install -U -r requirements.txt

Streamlined Operation:

For a concise, unified approach to running and managing the miners, a Bash script can be used, allowing specified configurations, such as the number of GPUs, CPU cores, enabling OpenCL, and more. This simplifies the entire process, aiding users in launching and managing the mining operation effectively. Here's a quick running example. More details check Bash Script Usage and Options.

$ chmod +x miner.sh
$ ./miner.sh

Bash Script Usage and Options:

$ ./miner.sh -g <num_of_gpus> -c <num_of_cpu_cores> [-d] [-o] [-s] [-l] [-h]

Options:

  -g, --gpus <num>           Number of GPUs (Default: 1)
  -c, --cpucores <num>       Number of CPU cores; activates CPU mode if >0 (Default: 0)
  -d, --devfee, --dev-fee-on Enable dev fee (Default: off)
  -o, --opencl               Enable OpenCL computation (Default: off)
  -s, --silence              Run in silence/background mode (Default: off)
  -l, --logging-on           Record verified blocks into payload.log file (Default: off)"
  -h, --help                 Display help message and exit

Advanced Operations and Customizations

The detailed operations and customizations provided in this section are not mandatory for all users but are intended for those who wish to understand the intricacies and tailor the mining operation to their needs.

Component Responsibilities:

1. xengpuminer:

   • Executes offline, local mining through files.
   • Operates independently of network connectivity.

2. miner.py:

   • Outputs the difficulty.txt file.
   • Monitors, verifies, and uploads blocks found in the gpu_found_blocks_tmp directory.
   • Requires network connectivity to upload verified blocks.

Using xengpuminer with Advanced Options

xengpuminer provides several advanced options to help you configure your mining processes more precisely. Here's a guide on how to utilize these options effectively:

1. List Devices:

   $ ./xengpuminer -l -m <DEVICE_TYPE>

   The -l flag lists all available devices. Replace <DEVICE_TYPE> with either cuda or opencl to list the corresponding type of devices available on your system. For instance:

   $ ./xengpuminer -l -m cuda

   Lists all CUDA-compatible devices available.

2. Select Mode:

   $ ./xengpuminer -m <MODE>

   The -m flag allows you to choose the mode in which to run xengpuminer. Replace <MODE> with cuda for CUDA, opencl for OpenCL. For example:

   $ ./xengpuminer -m opencl

   Executes xengpuminer in OpenCL mode.

3. Specify Device:

   $ ./xengpuminer -d <INDEX>

   The -d flag lets you use the device with the specified index. Replace <INDEX> with the index of the device you want to use. For instance:

   $ ./xengpuminer -d 0

   Uses the first device on the list of available devices.

4. Define Batch Size:

   $ ./xengpuminer -b <N>

   The -b flag denotes the number of tasks per batch. Replace <N> with the desired batch size. For example:

   $ ./xengpuminer -b 16

   Processes 16 tasks per batch, which can be optimal depending on your device's capabilities and your specific needs.

5. Display Help:

   $ ./xengpuminer -?

   Shows help for xengpuminer's options and exits, providing quick reference to the options available for configuration.

Advanced Options for miner.py:

You can configure miner.py using command-line arguments or the config.conf file. Command-line arguments will override the corresponding settings in config.conf.

Command-Line Arguments: --account: Specify the account address for receiving mining rewards. --dev-fee-on: Enable the developer fee to support the project. --gpu: Set to true to enable GPU mode, false to run in CPU mode.

Configuring Account in config.conf: Replace the default account address in config.conf with your own to receive mining rewards:

account = YOUR_ACCOUNT_ADDRESS  # Replace with your actual account address
