XMR_ARCH64
XMR_ARCH64 is high performance Monero (XMR) CPU miner for Arch64 Linux on RPi3 board.
Windows support inherited from xmrig/xmrig will be discarded in further development.
Originally forked from xmrig/xmrig with full development in C++11.
- Roadmap for next releases.

Usage
Quick start
./xmr_arch64
config.json from working folder will be used. config.json examples can be found in src folder
Basic example
./xmr_arch64 -o pool.monero.hashvault.pro:5555 -u YOUR_WALLET -p x -k
Failover
./xmr_arch64 -o pool.monero.hashvault.pro:5555 -u YOUR_WALLET1 -p x -k -o pool.supportxmr.com:5555 -u YOUR_WALLET2 -p x -k
For failover you can add multiple pools, maximum count not limited.
Options
-a, --algo=ALGO cryptonight (default) or cryptonight-lite
-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
--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
--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 support
--print-time=N print hashrate report every N seconds
-h, --help display this help and exit
-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.
Algorithm variations
Since avujic/xmr_arch64 version 0.0.2
--av=1
For CPUs with hardware AES.--av=2
Lower power mode (double hash) of1
.--av=3
Software AES implementation.So far, only this option works on Arch64/Rpi3
--av=4
Lower power mode (double hash) of3
.
Common Issues
HUGE PAGES unavailable
- TBD
Other information
- No HTTP support, only stratum protocol support.
- No TLS support.
- Default donation 3% (3 minutes in 100 minutes) can be reduced to 1% via command line option
--donate-level
.
CPU mining performance
- Rpi3 ARCH64 - 7.3 H/s (8 threads)
- Rpi3 Raspbian - 5.3 H/s (4 threads)
- 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.
Maximum performance checklist
- Idle operating system.
- Do not exceed optimal thread count.
- Use modern CPUs with AES-NI instructuon set.
- Try setup optimal cpu affinity.
- Enable fast memory (Large/Huge pages).
