Intro

GxMiner acts as an application of library go-randomx which based on C and golang. In this framework, we can mine all cryptocurrencies with random-x series algorithm.

This repo is currently not fully open-sourcing, but its core part, the project go-randomx is open-sourcing, if you wanna help boost GxMiner's speed you can directly post PR to the go-randomx

We plan to open-source after monero's fork on 30 Nov.

Why GxMiner

As everyone know, xmrig & xmr-stak is the leader of monero miners. But soon monero is not cryptonight algorithm cryptocurrency any longer, it would be the centry of random-x

Comparing to the leaders, GxMiner is younger and modern, without any historical burden. And GxMiner is not slower even sometimes slightly faster than the xmrig.

And if you are a developer, it would be much easier to intergrate your random-x fork into miner.

Loki mining example:

gxminer.exe -o hk.loki.herominers.com:10111 -u L7zjr6vtpyvBtFjgbjcWAu1SYjLRutW518J9Y8LqP4GgYanhRJJSmF37X83YUTJaTr16y8RUtWynAM6DK6Jkx7qVUTMfFie

Config

Configuration sequence: ConfigFile > CLI > Setup

Config File will be auto-generated after setup follow or running with CLI

example:

{
  "pools": [
    {
      "pool": "rx.minexmr.com:6666",
      "user": "47wcnDjCDdjATivqH9GjC92jH9Vng7LCBMMxFmTV1Ybf5227MXhyD2gXynLUa9zrh5aPMAnu5npeQ2tLy8Z4pH7461vk6uo",
      "pass": "x",
      "rig-id": "",
      "tls": true,
      "nicehash": false
    }
  ],
  "workers": {
    "worker-num": 2,
    "init-num": 2,
    "huge-page": true,
    "hard-aes": true,
    "full-mem": true,
    "jit": true,
    "argon2-sse3": true,
    "argon2-avx2": true,
    "affinity-mask": "f"
  },
  "log": {
    "level": "debug",
    "file": ""
  },
  "http": {
    "port": 2333,
    "external": false
  }
}

The second pool acts as the failover pool config.

HTTP API

Build

0x00 get ready building environment

• Windows: msys2(base-devel) & latest golang
• Ubuntu: build-essential & latest golang

0x01 clone the repo with --recursive flag

git clone --recursive https://github.com/maoxs2/GxMiner

0x02 build with bash command

bash build.sh random-x

support:

• random-x
• random-xl
• random-wow
• random-arq
• random-yada
• random-sfx

0x04 binary will be generated in the sub-folder

For example, random-xl gxminer will be built in "random-xl" folder

0xFF intergrate your RandomX

After git clone (the step1), edit go-randomx/build.sh

if [ ! -d "RandomX" ]; then
  git clone https://github.com/maoxs2/RandomX RandomX
fi

Replace https://github.com/maoxs2/RandomX with your random-x fork, like https://github.com/safex/RandomSFX

Then build with bash command like step2, change the random-x to your fork's branch, like master or SFX-v1.1.6 etc

FAQ

1. Start the miner with "failed to alloc mem for dataset" error or "failed to alloc mem for cache" error, how to deal?

• Check your platform support large/huge page or not. if not, set --huge-page=false(not recommended).
• sysctl -w vm.nr_hugepages=1250 on linux(change 1250 to 2500 if you have 2 NUMA).
• Check whether you have enough page. If not, clear it.
• tevador/RandomX#100 (comment) (auto-TrySetLockPagesPrivilege since v0.1.8)

2. How to get maximum hashrate?

• Keep --hard-aes, --full-mem, --jit and --huge-page all be true (enabled) as default.
• In system setting, set your virtual memory larger than 4GB.
• Test the --workerNum and select the one with fastest hashrate.

3. Why always "invalid job id"?

• Check the network delay and packet loss between miner and pool.
• Choose a pool with great network status is important.
