ulordrig is a high performance Ulord CPU miner, with official support for Linux and Windows.

Table of contents

Features

  • High performance.
  • Official Windows support.
  • Small Windows executable, without dependencies.
  • x86/x64 support.
  • keepalived support.
  • Command line options compatible with cpuminer.
  • Smart automatic CPU configuration.
  • It's open source software.

Install

Usage

As an example of testnet: ./ulordrig -o stratum+tcp://test-pool.ulord.one:7200 -u uTRHNH71eiW2KMc2rSwmanpXGgDeKMZXdW.worker1 -p x -t 1

Options

  -o, --url=URL            URL of mining server
  -O, --userpass=U:P       username:password pair for mining server
  -u, --user=USERNAME      username for mining server
  -p, --pass=PASSWORD      password for mining server
  -t, --threads=N          number of miner threads
  -v, --av=N               algorithm variation, 0 auto select
  -k, --keepalive          send keepalived for prevent timeout (need pool support)
  -r, --retries=N          number of times to retry before switch to backup server (default: 5)
  -R, --retry-pause=N      time to pause between retries (default: 5)
      --cpu-affinity       set process affinity to CPU core(s), mask 0x3 for cores 0 and 1
      --cpu-priority       set process priority (0 idle, 2 normal to 5 highest)
      --no-huge-pages      disable huge pages support
      --no-color           disable colored output
      --variant            algorithm PoW variant
      --user-agent         set custom user-agent string for pool
  -B, --background         run the miner in the background
  -c, --config=FILE        load a JSON-format configuration file
  -l, --log-file=FILE      log all output to a file
  -S, --syslog             use system log for output messages
      --max-cpu-usage=N    maximum CPU usage for automatic threads mode (default 75)
      --safe               safe adjust threads and av settings for current CPU
      --nicehash           enable nicehash/ulordrig-proxy support
      --print-time=N       print hashrate report every N seconds
      --api-port=N         port for the miner API
      --api-access-token=T access token for API
      --api-worker-id=ID   custom worker-id for API
  -h, --help               display this help and exit
  -V, --version            output version information and exit

Also you can use configuration via config file, default ulordrig/src/config.json. You can load multiple config files and combine it with command line options.

Common Issues

HUGE PAGES unavailable

  • Run ulordrig as Administrator.
  • Ulordrig automatically enables SeLockMemoryPrivilege for current user, but reboot or sign out still required. Manual instruction.

Other information

  • No HTTP support, only stratum protocol support.
  • No TLS support.

CPU mining performance

  • Intel(R) Xeon(R) CPU E3-1231 v3 - 860 H/s (8 threads)

Please note performance is highly dependent on system load. The numbers above are obtained on an idle system. Tasks heavily using a processor cache, such as video playback, can greatly degrade hashrate. Optimal number of threads depends on the size of the L3 cache of a processor, 1 thread requires 1 MB of cache.

Maximum performance checklist

  • Idle operating system.
  • Do not exceed optimal thread count.
  • Use modern CPUs with AES-NI instruction set.
  • Try setup optimal cpu affinity.
  • Enable fast memory (Large/Huge pages).
