Introduction <<<

This is a CUDA accelerated mining application for use with
Monero and other coins based on the Cryptonight algorithm.


Command Line Interface <<<

This code is based on the main ccminer branch, that in turn
is based on the pooler cpuminer 2.3.2 release and inherits
most of their command line interface and options.

-d, --devices gives a comma separated list of CUDA device IDs
to operate on. Device IDs start counting from 0!
Alternatively give string names of your card like
gtx780ti or gt640#2 (matching 2nd gt640 in the PC).
-l, --launch=CONFIG launch config for the Cryptonight kernel.
a comma separated list of values in form of
AxB where A is the number of threads to run in
each thread block and B is the number of thread
blocks to launch. If less values than devices in use
are provided, the last value will be used for
the remaining devices. If you don't need to vary the
value between devices, you can just enter a single
value and it will be used for all devices.
(default: 8x40)
--bfactor=X Enables running the Cryptonight kernel in smaller pieces.\n
The kernel will be run in 2^X parts according to bfactor,\n
with a small pause between parts, specified by --bsleep.\n
This is a per-device setting like the launch config.\n
(default: 0 (no splitting) on Linux, 6 (64 parts) on Windows)\n
--bsleep=X Insert a delay of X microseconds between kernel launches.\n
Use in combination with --bfactor to mitigate the lag\n
when running on your primary GPU.\n
This is a per-device setting like the launch config.\n
-f, --diff Divide difficulty by this factor (std is 1)
-o, --url=URL URL of mining server (default: " DEF_RPC_URL ")
-O, --userpass=U:P username:password pair for mining server
-u, --user=USERNAME username for mining server
-p, --pass=PASSWORD password for mining server
--cert=FILE certificate for mining server using SSL
-x, --proxy=[PROTOCOL://]HOST[:PORT] connect through a proxy
-t, --threads=N number of miner threads
(default: number of nVidia GPUs in your system)
-r, --retries=N number of times to retry if a network call fails
(default: retry indefinitely)
-R, --retry-pause=N time to pause between retries, in seconds (default: 15)
-T, --timeout=N network timeout, in seconds (default: 270)
-s, --scantime=N upper bound on time spent scanning current work when
long polling is unavailable, in seconds (default: 5)
--no-longpoll disable X-Long-Polling support
--no-stratum disable X-Stratum support
-q, --quiet disable per-thread hashmeter output
-D, --debug enable debug output
-P, --protocol-dump verbose dump of protocol-level activities
-B, --background run the miner in the background
--benchmark run in offline benchmark mode
-c, --config=FILE load a JSON-format configuration file
-V, --version display version information and exit
-h, --help display this help text and exit


Notable contributors to this application are:


  • CUDA implementation for the Cryptonight algorithm.

Christian Buchner, Christian H. (Germany):

  • modifying the original pooler-cpuminer for use with CUDA.

Jeff Garzik, pooler + contributors:

  • The original pooler-cpuminer project


  • JSON-RPC 2.0 handling and the Cryptonight C-code comes
    from his cpuminer fork, cpuminer-multi
