Default is 1. --texture-cache comma separated list of flags (0/1/2) specifying which of the CUDA devices shall use the texture cache for mining. Kepler devices may profit. --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 <<< June 2016 v1.8.0 Pascal support with cuda 8 x11evo algo (XRE) May 18th 2016 v1.7.6 Decred vote support X17 cleanup and improvement Add mining.ping stratum method and handle unknown methods Implement a pool stats/benchmark mode (-p stats on yiimp) Add --shares-limit parameter, can be used for benchmarks Mar. 13th 2016 v1.7.5 Blake2S Algo (NEVA/OXEN) Feb. 28th 2016 v1.7.4 (1.7.3 was a preview, not official) Decred simplified stratum (getwork over stratum) Vanilla kernel by MrMad Drop/Disable WhirlpoolX Feb. 11th 2016 v1.7.2 Decred Algo (longpoll only) Blake256 improvements/cleanup Jan. 26th 2016 v1.7.1 Implement sib algo (X11 + Russian Streebog-512/GOST) Whirlpool speed x2 with the midstate precompute Small bug fixes about device ids mapping (and vendor names) Add Vanilla algo (Blake256 8-rounds - double sha256) Nov. 06th 2015 v1.7 Improve old devices compatibility (x11, lyra2v2, quark, qubit...)

Create also the pentablake algo (5x Blake 512) Sept 6th 2014 Almost twice the speed on blake256 algos with the "midstate" cache Sep. 1st 2014 add X17, optimized x15 and whirl add blake (256 variant) color support on Windows, remove some dll dependencies (pthreads, msvcp) Aug. 18th 2014 add X14, X15, Whirl, and Fresh algos, also add colors and nvprof cmd line support June 15th 2014 add X13 and Diamond Groestl support. 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.
