Table of contents

Cpuminer-opt is a CPU mining software. There are two versions in the archive. Cpuminer-opt and Cpuminer-gr for Raptoreum cryptocurrency.

 

The cpuminer-gr version is a fork of cpuminer-opt by JD, which is a fork of cpuminer-multi with optimizations imported from other miners. There is another fork - a multi-threaded termux miner with a large number of algorithms. And for mining Ethereum on the CPU, UselethMiner is used.

The coins mined by this program can be tracked here.

Setting up a batch file

 

  1. cpuminer.exe - specify the name of the program to be launched. For cpuminer-opt it will be different -cpuminer-avx2.exe
  2. -o stratum+tcp://eu.vrm.mining-pool.ovh - specify the pool address
  3. :3032 - put a colon and specify the port from the pool
  4. Weblogin - after the key -u, specify either the login on the pool, if registration is needed there, or the address of your wallet

  5. WorkerName - specify the name of the worker (rig name)
  6. -p WorkerPassword - specify the password. Set Xif there is no password

Configuration via a configuration file on the example of Raptoreum

To run the program through the configuration file and the Raptoreum cryptocurrency, we need to create a config.json file in the cpuminer-gr folder. Just create .txta file and then change its extension .txt from .json. Open this file for editing in any text editor. For example in Notepad. Inside this file you need to place the following code:

{
  "url": "stratum+tcps://us.flockpool.com:5555",
  "url-backup": "stratum+tcps://us-west.flockpool.com:5555",
  "user": "R9fRZ7jdrPMtj6sHxsfjnYJHZKFtThyc4u.MainPC",
  "pass": "password",
  "algo": "gr"
}

Your region for urlmust have the lowest ping, and the reserve pool ( "url-backup") must be located below. We recommend using SSL (5555) as the port. Your worker can be anything; this is the ID of the specific machine you are mining on.

Finally, the password is used when you want to withdraw money, so set it to be hard to guess.

Alternatively, you can use Flockpool's Start Mining tool to automatically tune the config.json file. If you do, just delete the original config.json and fill in all the options on the Flockpool page. After that, download the configuration file you just created and move it to the cpuminer-gr folder. Remember that the settings for a pool are usually written on the pools themselves.

Command Line Arguments

Pool connection:

-o, --url=URL address of the mining pool

-O, --userpass=U:P pair password:user for mining pool

-u, --user=USERNAME username for mining pool (can be wallet address or pool login)

-p, --pass=PASSWORD mining pool password

--cert=FILE specify certificate for mining server using SSL

-x, --proxy=[PROTOCOL://]HOST[:PORT] connect via proxy

-c, --config=FILE load configuration file in JSON format

Server connection:

-r, --retries=N specify the number of retries before switching to the backup pool server (default: repeat indefinitely)

-R, --retry-pause=N pause time between connection attempts (default: 30)

--time-limit=N maximum time [s] before exiting the program. (default: 300 seconds)

-T, --timeout=N set network connection timeout (default 300)

-s, --scantime=N set the upper limit of the current job search time, in seconds (default: 10)

--randomize start randomizing search range to reduce duplicate work

-f, --diff-factor divides the difficulty by this factor (default 1.0)

-m, --diff-multiplier multiplies the difficulty by this factor (default 1.0)

Performance:

-t, --threads=N specify number of CPU threads (default: number of processors)

-1, --oneways=N you can specify the number of "gateway" streams that will accompany your "standard" streams. The default method is determined by your CPU instruction set. (default:0)

--cpu-affinity set affinity to main cpu core by mask 0x3 for cores 0 and 1

--cpu-priority set priority. 0 - inactive, 2 normal, 5 - highest)

--max-rate=N[KMG] only mine if the net hash rate is less than the specified value

--max-diff=N only mine if the difficulty is less than the given value. Can be configured with --resume-diff=N to set the value of resume mining

--ryzen Force AVX and disable AVX2. Ryzen 1*** much faster

-n, --nfactor specify N-Factor

Program interface:

-q, --quiet disable per-thread hash output

--no-color disable colored console output

-D, --debug enable debug output

-P, --protocol-dump allows you to write the event log

--show-diff displays current block and network difficulty

-B, --background run the miner in the background

Solo mining:

--coinbase-addr=ADDR specify payout address for SOLO mining

--coinbase-sig=TEXT specify text data to insert if possible

--no-longpoll disable X-Long-Polling support

--no-getwork disable getwork support

--no-gbt disable getblocktemplate support

--no-stratum disable X-stratum protocol support

--no-extranonce disable Stratum extranonce protocol support

--no-redirect ignore requests to change the URL of the mining server

Testing:

--benchmark run the program in offline testing mode

--cputest start debug mode of hashes of processor algorithms

Temperatures:

--max-temp=N start mining only if the temperature is less than the specified value (Linux only)

API:

-b, --api-bind port for miner API (default: 127.0.0.1:4068), 0 disabled

--api-remote allow remote control of the program

Reference:

-V, --version display version information and exit

-h, --help display help text and exit

Other settings:

--cpu-affinity-stride N specify how many processors to skip when assigning affinity based affinity, cannot be used with '--cpu-affinity' (default: 1) See README.md for more details.

--cpu-affinity-default-index N specify which processor will run thread affinity by default. (default: 0) See README.md for more details.

--cpu-affinity-oneway-index N specify which processor will run thread affinity by default. (default: [After default threads]) See README.md for more details. --cpu-priority-oneway 0-5

--cpu-priority-oneway 0-5 specify what priority gateway threads have (0 is the lowest, 5 is the highest) (default: 0)

Requirements

  • x86_64 architecture processor with minimal SSE2 support. This includes Intel Core2 and newer and AMD equivalents. To take advantage of the AES_NI optimization, a processor with AES_NI is required. This includes Intel Westmere and newer and AMD equivalents. Further optimization is available for some algorithms for processors with AVX and AVX2, Sandybridge and Haswell, respectively.
  • Old processors are supported by another program - cpuminer-multi TPruvot, but with reduced performance.
  • ARM processors are not supported.
  • 64-bit Linux OS. Ubuntu and Fedora based distributions, including Mint and Centos, work and have all dependencies in their repositories.
  • 64-bit Windows OS is supported with mingw_w64 and msys or prebuilt binaries.
  • MacOS, OSx and Android are not supported.
  • Pool with Stratum protocol. Some algorithms may work using getwork or GBT. YMMV.

Basic instructions for building *nix (Linux, Debian, Ubuntu)

To build the termux version, run the following script:

 ./autogen.sh    # only needed if building from git repo
 ./nomacro.pl    # only needed if building on Mac OS X or with Clang
 ./configure CFLAGS="*-march=native*" --with-crypto --with-curl
 # Use -march=native if building for a single machine
 make

Note for Debian/Ubuntu users:

 apt-get install automake autoconf pkg-config libcurl4-openssl-dev libjansson-dev libssl-dev libgmp-dev zlib1g-dev make g++ libtool
