Luffa (Joincoin) Keccak (Maxcoin) Pentablake (Blake 512 x5) 1Coin Triple S Neoscrypt (FeatherCoin) Scrypt and Scrypt:N Scrypt-Jane (Chacha) Skein (Skein + SHA) Woodcoin (Double Skein) Vertcoin Lyra2RE Ziftrcoin (ZR5) where some of these coins have a VERY NOTABLE nVidia advantage over competing AMD (OpenCL Only) implementations. We did not take a big effort on improving usability, so please set your parameters carefuly. THIS PROGRAMM IS PROVIDED "AS-IS", USE IT AT YOUR OWN RISK! If you're interessted and read the source-code, please excuse that the most of our comments are in german. >>> Command Line Interface <<< This code is based on the pooler cpuminer and inherits its command line interface and options. -a, --algo=ALGO specify the algorithm to use blake use to mine Saffroncoin (Blake 256) blakecoin use to mine Old Blake 256 bmw use to mine Midnight c11/flax use to mine Chaincoin and Flax deep use to mine Deepcoin dmd-gr use to mine Diamond-Groestl fresh use to mine Freshcoin fugue256 use to mine Fuguecoin groestl use to mine Groestlcoin heavy use to mine Heavycoin jackpot use to mine Jackpotcoin keccak use to mine Maxcoin luffa use to mine Joincoin lyra2 use to mine Vertcoin mjollnir use to mine Mjollnircoin myr-gr use to mine Myriad-Groest neoscrypt use to mine FeatherCoin nist5 use to mine TalkCoin penta use to mine Joincoin / Pentablake quark use to mine Quarkcoin qubit use to mine Qubit scrypt use to mine Scrypt coins scrypt:N use to mine Scrypt-N (:10 for 2048 iterations) scrypt-jane use to mine Chacha coins like Cache and Ultracoin s3 use to mine 1coin skein use to mine Skeincoin skein2 use to mine Woodcoin x11 use to mine DarkCoin x14 use to mine X14Coin x15 use to mine Halcyon x17 use to mine X17 whirlpoolx use to mine Vanilla zr5 use to mine ZiftrCoin -d, --devices gives a comma separated list of CUDA device IDs to operate on.

Alternatively give string names of your card like gtx780ti or gt640#2 (matching 2nd gt640 in the PC). -i, --intensity=N[,N] GPU threads per call 8-25 (2^N + F, default: 0=auto) Decimals and multiple values are allowed for fine tuning -f, --diff-factor Divide difficulty by this factor (default 1.0) -m, --diff-multiplier Multiply difficulty by this value (default 1.0) --vote=VOTE block reward vote (for HeavyCoin) --trust-pool trust the max block reward vote (maxvote) sent by the pool -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 --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) --time-limit maximum time [s] to mine before exiting the program. -T, --timeout=N network timeout, in seconds (default: 300) -s, --scantime=N upper bound on time spent scanning current work when long polling is unavailable, in seconds (default: 5) -n, --ndevs list cuda devices -N, --statsavg number of samples used to display hashrate (default: 30) --no-gbt disable getblocktemplate support (height check in solo) --no-longpoll disable X-Long-Polling support --no-stratum disable X-Stratum support -q, --quiet disable per-thread hashmeter output --no-color disable colored output -D, --debug enable debug output -P, --protocol-dump verbose dump of protocol-level activities -b, --api-bind IP/Port for the miner API (default: 127.0.0.1:4068) --api-remote Allow remote control --max-temp=N Only mine if gpu temp is less than specified value --max-rate=N[KMG] Only mine if net hashrate is less than specified value --max-diff=N Only mine if net difficulty is less than specified value --pstate=0 will force the Geforce 9xx to run in P0 P-State --plimit=150W set the gpu power limit, allow multiple values for N cards --keep-clocks prevent reset clocks and/or power limit on exit -B, --background run the miner in the background --benchmark run in offline benchmark mode --cputest debug hashes from cpu algorithms --cpu-affinity set process affinity to specific cpu core(s) mask --cpu-priority set process priority (default: 0 idle, 2 normal to 5 highest) -c, --config=FILE load a JSON-format configuration file -V, --version display version information and exit -h, --help display this help text and exit Scrypt specific options: -l, --launch-config gives the launch configuration for each kernel in a comma separated list, one per device. --interactive comma separated list of flags (0/1) specifying which of the CUDA device you need to run at inter- active frame rates (because it drives a display). -L, --lookup-gap Divides the per-hash memory requirement by this factor by storing only every N'th value in the scratchpad. Default is 1. --no-autotune disable auto-tuning of kernel launch parameters >>> 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 <> -p <> -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 <> -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 <> -p <> 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 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. >>> RELEASE HISTORY <<< August 2015...

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. >>> AUTHORS <<< Notable contributors to this application are: Christian Buchner, Christian H.
