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 2.3.2 release and inherits its command line interface and options. -a, --algo=ALGO specify the hash algorithm to use bitcoin Bitcoin blake Blake 256 (SFR/NEOS) blakecoin Fast Blake 256 (8 rounds) c11 X11 variant deep Deepcoin dmd-gr Diamond-Groestl fresh Freshcoin (shavite 80) fugue256 Fuguecoin groestl Groestlcoin jackpot Jackpot keccak Keccak-256 (Maxcoin) luffa Doomcoin lyra2v2 VertCoin myr-gr Myriad-Groestl neoscrypt neoscrypt (FeatherCoin) nist5 NIST5 (TalkCoin) penta Pentablake hash (5x Blake 512) quark Quark qubit Qubit sia Siacoin (at pools compatible to siamining.com) skein Skein SHA2 (Skeincoin) s3 S3 (1Coin) spread Spread x11 X11 (DarkCoin) x13 X13 (MaruCoin) x14 X14 x15 X15 x17 X17 (peoplecurrency) vanilla Blake 256 8 rounds yescrypt yescrypt whirl Whirlcoin (old whirlpool) whirlpoolx Vanillacoin -d, --devices Comma separated list of CUDA devices to use.

The wallet must also be started with the -server option and/or with the server=1 flag in the .conf file >>> 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 <<< 2015-02-01 Release 1.0, forked from tpruvot and sp-hash 2015-02-03 v1.01: bug fix for cards with compute capability 3.0 (untested) 2015-02-09 v1.02: various bug fixes and optimizations 2015-03-08 v2.00: added whirlpoolx algo (Vanillacoin), also various optimizations and bug fixes 2015-03-30 v3.00: added skein (for Myriadcoin for example) 2015-05-06 v4.00: added Neoscrypt 2015-05-15 v4.01: fixed crash after ctrl-c (Windows), fixed -g option 2015-07-06 v5.00: -g option removed, some bug fixes and optimizations 2015-07-08 v5.01: lyra2 optimization 2015-08-22 v6.00: remove Lyra2RE, add Lyra2REv2, remove Animecoin, remove yesscrypt 2016-05-03 v6.01: various bug fixes and optimizations 2016-05-12 v6.02: faster x17 and quark 2016-05-16 v7.00: added Vanillacoin, optimized blake and blakecoin, added stratum methods used by yiimp.ccminer.org 2016-05-16 v7.01: stratum.get_stats bug fix 2016-06-02 v7.02: fix default intensity for Nist5 fix power usage statistics 2016-06-11 v7.03: faster lyra2v2 2016-06-18 v7.04: Neoscrypt optimization Bug Fixes 2016-08-11 v8.00: added Siacoin 2016-08-12 v8.01: increse default intensity for Sia fix Linux build 2016-09-29 v8.02: change to CUDA 8.0 on Windows various small changes 2016-12-08 v8.03: fix memory leak in Neoscrypt 2016-12-13 v8.04: fix illegal memory access in X11-X17 fix duplicate shares in skein 2016-12-17 v8.05: fix Skein bug 2017-03-12 v8.06: Heavy and Mjollnir algos removed 2017-05-18 v8.07: Bitcredit algo removed fixed bugs in bitcoin and jackpot algo 2017-05-19 v8.08: fix Makefile and configure.ac for Linux >>> AUTHORS <<< Notable contributors to this application are: Christian Buchner, Christian H.
