Mining on CPU

This tutorial is divided into Windows and Docker, Docker is also suitable for running in the server.

The mining pools currently supporting STC are as follows:

For Windows User

Download XMRig

Select and download the win64 version of the XMRig program.

Modify script

After downloading the XMRig program, unzip and right-click to "edit" the start.cmd file.

Modify the content of the start.cmd file:

@echo off
xmrig.exe --donate-level 1 -a cn/r -o ccc.zxxx123.com:22 -u an.1 -p x -k --user-agent Ibctminer/1.0.0
pause

The modified result is shown in the following figure:

Double-click to run

double-click the start.cmd file.

For Docker User

sudo docker run -d -it \
    --name starcoin-xmr \
    --restart=always \
    z0re/xmrig-stc \
    -o ccc.zxxx123.com:22 \
    -u an.1 \
    -p x \
    -a cn/r \
    --donate-level 1 \
    --cpu-max-threads-hint 90

Command Explanation:

• -d: run the container in the background;

• --name starcoin-xmr: specify the container name;

• --restart=always: If the container exits unexpectedly, it will automatically restart;

• -o ccc.zxxx123.com:22: mining pool address, such as cola ccc.zxxx123.com:22;

• -u an.1: <sub-account name>.<number>, such as an.1;

• -p x : password, just fill x;

• -a cn/r: algorithm, cn/r, do not change, only use this;

• --donate-level: dev fee;

• --cpu-max-threads-hint 90: CPU usage ratio;

Performance Optimization

Enable Huge Pages

According to the official documentation of XMRig, enabling Huge Pages can increase the computing power by 20%~30%. The tutorial is as follows.

For Windows

Step 1:

Windows Server 2003 Resource Kit Tools must be installed first (provides SeLockMemoryPrivilege function)

Download link: https://wwa.lanzoui.com/b0f8hmm6b password: star

After downloading, unzip it, and install rktools as an administrator. If it prompts an incompatible popup, you can close it and ignore it.

Step 2:

Open a CMD window with administrator:

Enter the following command in the CMD window:

ntrights -u "这里换成自己的Windows账户名" +r SeLockMemoryPrivilege

The prompt "successful" is successful, and then you must restart the computer! ! !

Step 3:

After restarting the computer, run the script again to see the effect.

For Linux

Temporarily enable:

sudo sysctl -w vm.nr_hugepages=1280

Persistence is enabled (it also takes effect after restart):

sudo bash -c "echo vm.nr_hugepages=1280 >> /etc/sysctl.conf"

Modify the CPU thread usage occupancy ratio

Modify file: start.cmd

--cpu-max-threads-hint 80: The ratio of the maximum number of threads automatically configured.

Modify the number of threads

Modify file: start.cmd

-t 4: specify 4 threads; don't tune too much, it may backfire;

Check the number of threads in effect:
