# EMC CLI Download and Mining ## 1. EMC CLI Download ### Visit the EMC test network Visit EMC Test Network: ### Connect wallet

As shown in the above figure, click **\[Connect Walllet]** to proceed.

From the pop-up window, select your preferred wallet from the list on the left. Next, in the wallet plugin interface, complete the steps in the wallet Chrome extension: "**Connect**" -> "**Authorize**" -> "**Sign**". **Note:** During the wallet connection process, follow the prompt to switch to the EMC Testnet network (Visit [EMC Testnet RPC Information](https://docs.emc.network/emc-testnet/emc-airdrop-guidelines/wallet-setup/method-2-manual-configuration/emc-testnet-network-rpc-information)).

Once connected, you can view your points and use an invitation code to invite friends. #### Install and Operate EMC CLI Program After the wallet connection is completed, you can proceed and click the **\[Install**] button in the image and select **\[CLI]** from the dropdown list.

Choose **\[Windows]** for the download and installation.

As shown above, select **\[Windows]** for download and installation.
### EMC CLI Files Locate the "**EMC\_Miner\_Windows"** folder on your local device. The file structure is shown below:

`emc_miner_cli.exe` The command line program for EMC testnet mining； `run_cli_help.cmd` Runs the command to view the help documentation； `run_cpu_only.cmd` Runs the command to enable CPU-only mining； `run_gpu_only.cmd` Runs the command to enable GPU-only mining； ## 2. EMC CLI Mining Operations AI mining modes: * Basic mining * Advanced mining ### Basic Mining Basic mining lets you choose between CPU-only or GPU-only mining. ### **EMC CLI CPU-Only Mining** Run`run_cpu_only.cmd`，right-click, and select **"Run as Administrator"**

Enter your private key to start CPU mining. EMC CLI automatically detects your hardware, initializes, and connects to the node. The information shown confirms successful CPU mining and rewards earned. **Note：** 1. Before running **`run_cpu_only.cmd`**, make sure the address has enough Gas fees (see the section on getting Gas fees). Otherwise, errors will occur, and mining won't start. 2. To view your CPU mining rewards, go to the EMC testnet explorer and enter your mining address. 3. To stop mining, press **`Ctrl + C`** in the command terminal and enter **`Y`**to confirm. ### **EMC CLI GPU Mining** Run **`run_gpu_only.cmd`**, right-click, and select "**Run as Administrator."** In the command terminal, enter your private key.

As shown in the image, before starting GPU mining, ensure that the Windows version of Docker is successfully installed and the Docker service is running. Otherwise, mining cannot proceed. **Note:** 1. Before running `run_cpu_only.cmd`, ensure that the address has sufficient gas fees (access the gas fee allocation section). Otherwise, an error will occur, preventing successful mining. 2. To clearly understand and verify CPU mining earnings, enter your mining address in the EMC testnet browser to check. 3. During mining, press `Ctrl + C` in the command line terminal to stop mining. In the command prompt that appears, enter `Y` to confirm the termination operation. #### EMC CLI Advanced Mining EMC CLI advanced mining supports simultaneous CPU and GPU mining, as well as enabling multi-threaded mining. **`emc_miner_cli` Command Line Parameters** First, locate the parent directory of the `emc_miner_cli.exe` program, for example: `"D:\EMC_Miner_Windows-1.5.0\EMC_Miner_Windows\"`. Then, in the CMD terminal, enter the relevant commands as shown in the image:

Refer to the help documentation by entering the following command: ```powershell emc_miner_cli.exe -h ```

**Description** : * `cpu_enable` : Enable or disable CPU mining. * `cpu_thread` Specifies the number of CPU threads to use. * `gpu_enable` : Enable or disable GPU mining. * `- gpu_model` : Specify the GPU serial number to use. * `gpu_thread` Specifies the number of GPU threads to use. * `miner_private` : Your wallet private key (required). #### **EMC CLI Advanced CPU Mining** Default CPU miningIn the CMD client, enter the following command and press the **Enter key**: ```powershell emc_miner_cli.exe --cpu_enable=true --gpu_enable=false --miner_private= ```

As shown in the image above, the default CPU mining is successful. #### **Multi-threaded CPU Mining** In the CMD client, enter `wmic` to check the number of CPU cores and threads on the computer:

The image shows that the local computer's CPU has 24 cores and 32 threads. Then, enter the mining command and press the Enter key: ```powershell emc_miner_cli.exe --cpu_enable=true --gpu_enable=false --cpu_thread=counts --miner_private=your wallet private key ``` * **Description** : * `Number of threads`: Set according to the number of your CPU cores (for example, use `10` threads). * `Your wallet private key`: Replace with your actual wallet private key

The figure shows that EMC CLI successfully mined CPU with 10 threads.
#### **EMC CLI Advanced GPU Mining** **Specify GPU serial number for mining** For devices with multiple graphics cards installed, EMC CLI supports specifying a GPU serial number for mining. \ **View GPU serial number** Before starting GPU mining, you need to check the available GPU serial numbers in your computer.In the CMD terminal, enter the following command and press the **Enter key**: ```powershell emc_miner_cli.exe -g ```

**Specify GPU mining**In the cmd end point, enter the following: ```powershell emc_miner_cli.exe --cpu_enable=false --gpu_enable=true --gpu_model= --miner_private= ```

As shown in the above figure, GPU 1 is designated for mining. **Note:** Before starting mining, ensure that the Docker Engine is running. Otherwise, the following error occurs:

**Multi-threaded GPU mining** At the cmd end point, enter the mining command and **press Enter** : ```powershell emc_miner_cli.exe --cpu_enable=false --gpu_enable=true --gpu_model= --gpu_thread= --miner_private= ``` * **Description** : * `GPU serial number` : The selected GPU serial number. * `Number of threads` : The number of threads allocated to the GPU mining task (e.g., using `4` threads). * `Your wallet private key` : Replace with your actual wallet private key

As shown in the above figure, specify graphics card 1 and start 4 processes for GPU mining.
**EMC CLI CPU and GPU Dual Mining** To improve overall mining efficiency, EMC CLI supports multi-threaded participation in both CPU and GPU mining simultaneously.In the CMD terminal, enter the mining command and press the **Enter key**: ```powershell emc_miner_cli.exe --cpu_thread= --gpu_model= --gpu_thread= --miner_private= ``` * **Description** : * `GPU serial number` : The selected GPU serial number. * `Line CPU thread count` : The number of threads allocated to the CPU mining task (e.g., using `10` threads). * `Number of line GPU threads` : The number of threads allocated to the GPU mining task (e.g., using `4` threads). * `Your wallet private key` : Replace with your actual wallet private key

As shown in the image above, specify GPU 1 and allocate 4 processes for GPU mining and 10 processes for CPU mining. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
