>>> Examples <<<
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Example for Heavycoin Mining on heavycoinpool.com with a single gpu in your system
|
|
|
|
|
ccminer -t 1 -a heavy -o stratum+tcp://stratum01.heavycoinpool.com:5333 -u <<username.worker>> -p <<workerpassword>> -v 8
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Example for Heavycoin Mining on hvc.1gh.com with a dual gpu in your system
|
|
|
|
|
ccminer -t 2 -a heavy -o stratum+tcp://hvcpool.1gh.com:5333/ -u <<WALLET>> -p x -v 8
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Example for Fuguecoin solo-mining with 4 gpu's in your system and a Fuguecoin-wallet running on localhost
|
|
|
|
|
ccminer -q -s 1 -t 4 -a fugue256 -o http://localhost:9089/ -u <<myusername>> -p <<mypassword>>
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Example for Fuguecoin pool mining on dwarfpool.com with all your GPUs
|
|
|
|
|
ccminer -q -a fugue256 -o stratum+tcp://erebor.dwarfpool.com:3340/ -u YOURWALLETADDRESS.1 -p YOUREMAILADDRESS
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Example for Groestlcoin solo mining
|
|
|
|
|
ccminer -q -s 1 -a groestl -o http://127.0.0.1:1441/ -u USERNAME -p PASSWORD
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Example for Scrypt-N (2048) on Nicehash
|
|
|
|
|
ccminer -a scrypt:10 -o stratum+tcp://stratum.nicehash.com:3335 -u 3EujYFcoBzWvpUEvbe3obEG95mBuU88QBD -p x
|
|
|
|
|
|
|
|
|
|
For solo-mining you typically use -o http://127.0.0.1:xxxx where xxxx represents
|
|
|
|
|
the rpcport number specified in your wallet's .conf file and you have to pass the same username
|
|
|
|
|
and password with -O (or -u -p) as specified in the wallet config.
|
|
|
|
|
|
|
|
|
|
The wallet must also be started with the -server option and/or with the server=1 flag in the .conf file
|
|
|
|
|
|
|
|
|
|
>>> Configuration files <<<
|
|
|
|
|
|
|
|
|
|
With the -c parameter you can use a json config file to set your prefered settings.
|
|
|
|
|
An example is present in source tree, and is also the default one when no command line parameters are given.
|
|
|
|
|
This allow you to run the miner without batch/script.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
>>> API and Monitoring <<<
|
|
|
|
|
|
|
|
|
|
With the -b parameter you can open your ccminer to your network, use -b 0.0.0.0:4068 if required.
|
|
|
|
|
On windows, setting 0.0.0.0 will ask firewall permissions on the first launch. Its normal.
|
|
|
|
|
|
|
|
|
|
Default API feature is only enabled for localhost queries by default, on port 4068.
|
|
|
|
|
|
|
|
|
|
You can test this api on linux with "telnet <miner-ip> 4068" and type "help" to list the commands.
|
|
|
|
|
Default api format is delimited text. If required a php json wrapper is present in api/ folder.
|
|
|
|
|
|
|
|
|
|
I plan to add a json format later, if requests are formatted in json too..
|
|
|

|
|
|
|
|
|
|
|
>>> Additional Notes <<<
|
|
|
|
|
|
|
|
|
|
This code should be running on nVidia GPUs ranging from compute capability
|
|
|
|
|
3.0 up to compute capability 5.2. Support for Compute 2.0 has been dropped
|
|
|
|
|
so we can more efficiently implement new algorithms using the latest hardware
|
|
|
|
|
features.
|
|
|
|

Thanks to tsiv and to Bombadil for the contributions!
|
|
|
|
|
|
|
|
|
|
June 14th 2014 released Killer Groestl quad version which I deem
|
|
|
|
|
sufficiently hard to port over to AMD. It isn't
|
|
|
|
|
the fastest option for Compute 3.5 and 5.0 cards,
|
|
|
|
|
but it is still much faster than the table based
|
|
|
|
|
versions.
|
|
|
|
|
|
|
|
|
|
May 10th 2014 added X11, but without the bells & whistles
|
|
|
|
|
(no killer Groestl, SIMD hash quite slow still)
|
|
|
|
|
|
|
|
|
|
May 6th 2014 this adds the quark and animecoin algorithms.
|
|
|
|
|
|
|
|
|
|
May 3rd 2014 add the MjollnirCoin hash algorithm for the upcomin
|
|
|
|
|
MjollnirCoin relaunch.
|
|
|
|
|
|
|
|
|
|
Add the -f (--diff) option to adjust the difficulty
|
|
|
|
|
e.g. for the erebor Dwarfpool myr-gr SaffronCoin pool.
|
|
|
|
|
Use -f 256 there.
|
|
|
|
|
|
|
|
|
|
May 1st 2014 adapt the Jackpot algorithms to changes made by the
|
|
|
|
|
coin developers. We keep our unique nVidia advantage
|
|
|
|
|
because we have a way to break up the divergence.
|
|
|
|
|
NOTE: Jackpot Hash now requires Compute 3.0 or later.
|
|
|
|
|
|
|
|
|
|
April, 27 2014 this release adds Myriad-Groestl and Jackpot Coin.
|
|
|
|
|
we apply an optimization to Jackpot that turns this
|
|
|
|
|
into a Keccak-only CUDA coin ;) Jackpot is tested with
|
|
|
|
|
solo--mining only at the moment.
|
|
|
|
|
|
|
|
|
|
March, 27 2014 Heavycoin exchange rates soar, and as a result this coin
|
|
|
|
|
gets some love: We greatly optimized the Hefty1 kernel
|
|
|
|
|
for speed. Expect some hefty gains, especially on 750Ti's!
|
|
|
|
|
|
|
|
|
|
By popular demand, we added the -d option as known from
|
|
|
|
|
cudaminer.
|
|
|
|
|
|
|
|
|
|
different compute capability builds are now provided until
|
|
|
|
|
we figure out how to pack everything into a single executable
|
|
|
|
|
in a Windows build.
|
|
|
|
|
|
|
|
|
|
March, 24 2014 fixed Groestl pool support
|
|
|
|
|
|
|
|
|
|
went back to Compute 1.x for cuda_hefty1.cu kernel by
|
|
|
|
|
default after numerous reports of ccminer v0.2/v0.3
|
|
|
|
|
not working with HeavyCoin for some people.
|
|
|
|
|
|
|
|
|
|
March, 23 2014 added Groestlcoin support. stratum status unknown
|
|
|
|
|
(the only pool is currently down for fixing issues)
|
|
|
|
|
|
|
|
|
|
March, 21 2014 use of shared memory in Fugue256 kernel boosts hash rates
|
|
|
|
|
on Fermi and Maxwell devices. Kepler may suffer slightly
|
|
|
|
|
(3-5%)
|
|
|
|
|
|
|
|
|
|
Fixed Stratum for Fuguecoin. Tested on dwarfpool.
|
|
|
|
|
|
|
|
|
|
March, 18 2014 initial release.
