Windows users may need the Visual Studio 2005 Runtimes files installed for distributed binaries to run. Distributed binaries may or may not have one or more of the following features enabled. ********************* * REMOTE MINER SERVER ********************* Place a text file named banned.txt with IP addresses of banned clients in the bitcoin working directory. One IP address should be entered per line, so each IP address is separated by a newline. Remote miner server arguments -remoteserver Turns on the remote server. -remotebindaddr=x.x.x.x Bind server to specific adapter. The default is 127.0.0.1. Note that this will only accept connections from the local computer. -remotebindport=xxxxx Bind server to specific port. The default is 8335. -remotepassword=xxxxx Set a password to access the server. The default is a blank password. -distributiontype=connected|contributed Sets method used to distribute bitcoins. "connected" will distribute coins only to those clients that were connected when the block being solved was created. The distribution is based on each connected clients calculated hash rate against the total hash rate at the time a new block is created. "contributed" will accrue all hashes sent to the server for a given address since the last generated block. A client may freely disconnect and reconnect and will continue accumulating hashes to whatever address the client specified. The distribution of coins with this method is based on the hashes accrued by each address against the total hashes accured by everyone. The server will save the values when it shuts down and load them back up on startup. -resethashescontributed Resets the count of hashes contributed from each address. ********************* * REMOTE MINER CLIENT ********************* (ARGUMENTS MAY BE COMBINED WITH CUDA/OPENCL ARGUMENTS) Remote miner client arguments -server=x.x.x.x The address of the server to connect to. The default is 127.0.0.1. -port=xxxxx The port of the server. The default is 8335. -password=xxxxx The password to use when connecting to the server. The default is a blank password. -address=xxxxxxx The bitcoin address you want generated coins sent to. The default is blank. If the server is using the "connected" ditribution type, a blank address will make the client's share of generated coins be kept by the server. If the server is using the "contributed" distribution type, a blank address will mean the client contributes as normal, but the contribution is ignored when determining how to distribute any coins. -threads=x Start this number of miner threads. The default value is the number of cores on your processor if using a CPU miner, or 1 if using a GPU miner. ********************* * RPC MINER CLIENT ********************* (ARGUMENTS MAY BE COMBINED WITH CUDA/OPENCL ARGUMENTS) RPC miner client arguments -url=http://example.com:8332 The URL of the RPC server. -user=username The username used to connect to the RPC server. -password=password The password used to connect to the RPC server. -threads=x Start this number of miner threads. The default value is the number of cores on your processor if using a CPU miner, or 1 if using a GPU miner. -workrefreshms=xxxx Work will be refreshed from the server this often. Each thread that is started needs its own work. The default value is 4000ms. If you have a fast miner, or are using lots of threads, you might want to reduce this. -statsurl=http://example.com/stats/json The URL of a server that will respond with a json object of the server stats. Currently, only slush's server stats are available. The stats will be printed by the client every minute. Not specifying a url will result in no stats being displayed. ********************* * CUDA MINER ********************* CUDA miner arguments -gpu=X Turns on GPU processing on specific GPU device. Indexes start at 0. If you just use -gpu without =X it will pick the first device found. -aggression=X Specifies how many hashes (2^(X-1)) per kernel thread will be calculated. The default is 6. It starts at 1 and goes to 32, with each successive number meaning double the number of hashes. Sane values are 1 to 12 or maybe 14 if you have some super card. -gpugrid=X Specifies what the grid size of the kernel should be. Useful for fine tuning hash rate. -gputhreads=X Specifies how many threads per kernel invocation should run. Useful for fine tuning hash rate. -port=X Specifies the port that bitcoin will listen on. (When run in GUI or daemon) -rpcport=X Specifies the port that the rpc server will listen on. (When run in GUI or daemon) ********************* * OPENCL MINER ********************* Make sure bitcoinmineropencl.cl is in the bitcoin working directory for the server and rpc miner, and remotebitcoinmineropencl.cl for the remote miner. OpenCL miner arguments -platform=X Use specific OpenCL platform at index X. Indexes start at 0. Default is 0. -gpu=X Turns on GPU processing on specific GPU device on specified platform. Indexes start at 0. If you just use -gpu without =X it will pick the first device found. -aggression=X Specifies how many hashes (2^(X-1)) per kernel thread will be calculated. The default is 6. It starts at 1 and goes to 32, with each successive number meaning double the number of hashes. Sane values are 1 to 12 or maybe 14 if you have some super card. -gpugrid=X Specifies what the grid size of the kernel should be. Useful for fine tuning hash rate. -gputhreads=X Specifies how many threads per kernel invocation should run. Useful for fine tuning hash rate. -port=X Specifies the port that bitcoin will listen on. (When run in GUI or daemon) -rpcport=X Specifies the port that the rpc server will listen on. (When run in GUI or daemon) ********************* * SCREENSAVERS ********************* Place the .scr files you wish to use, as well as all the .dll files, and the .cubin files if you are doing CUDA mining, or .cl file if you are doing OpenCL mining in your Windows system32 folder if running a 32 bit OS, or SysWOW64 folder if using a 64 bit OS. The screensavers will show up in your screensavers list if you placed them in the correct location. Screensaver options can be set in the configuration dialog box. Leaving a field empty will result in using the default value.
