-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
--no-auto-update disable automatic updates
--variant algorithm PoW variant
--donate-level=N donate level, default 5% (5 minutes in 100 minutes)
--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

-V, --version output version information and exit
Also you can use configuration via config file, default config.json. You can load multiple config files and combine it with command line options.
--av=1For CPUs with hardware AES.--av=2Lower power mode (double hash) of1.--av=3Software AES implementation.--av=4Lower power mode (double hash) of3.
CNRig is compiled 100% statically and should work on a wide variety of Linux distributions, It has been tested with:
| Distro | Kernel | Compatible |
|---|---|---|
| Ubuntu 18.04 | 4.15 | Yes |
| Ubuntu 10.04 | 2.6.32 | Yes |
| CentOS 6 | 2.6.32 | Yes |
| CentOS 5 | 2.6.18 | Yes |
- No HTTP support, only stratum protocol support.
- No TLS support.
- Default donation 5% (5 minutes in 100 minutes) can be reduced to 1% via command line option
--donate-level.
- Intel i7-7700 - 307 H/s (4 threads)
- AMD Ryzen 7 1700X - 560 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 2 MB of cache.
- 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).
