Make sure to only download from this website or the correct github link Ales KatonaDerek CormackThe algorithm is memory hard and in order to fit the DAG into memory, it needs 1-2GB of RAM on each GPU.If you get Error GPU mining.you havent got enough memory.The GPU miner is implemented in OpenCL, so AMD GPUs will be 'faster' than same-category NVIDIA GPUs.ASICs and FPGAs are relatively inefficient and therefore discouraged.To get openCL for your chipset and platform, try: The following instructions are, for the most part, relevant to any system with Ubuntu 14.04 and a Nvidia GPU.Setting up an EC2 instance for mining You check your cooling status: The official Frontier release of geth only supports a CPU miner natively.We are working on a GPU miner, but it may not be available for the Frontier release.

Geth however can be used in conjunction with ethminer, using the standalone miner as workers and geth as scheduler communicating via JSON-RPC.The C++ implementation of Ethereum (not officially released) however has a GPU miner.It can be used from eth, AlethZero (GUI) and ethMiner (the standalone miner).You can install this via ppa on linux, brew tap on MacOS or from source.To install ethminer from source: To set up GPU mining you need a coinbase account.It can be an account created locally or remotely.ethminer communicates with geth on port 8545 (the default RPC port in geth).You can change this by giving the --rpcport option to geth.Ethminer will find get on any port.Note that you need to set the CORS header with --rpccorsdomain localhost.You can also set port on ethminer with -F http://127.0.0.1:3301.Setting the ports is necessary if you want several instances mining on the same computer, although this is somewhat pointless.If you are testing on a private cluster, we recommend you use CPU mining instead.

Also note that you do not need to give geth the --mine option or start the miner in the console unless you want to do CPU mining on TOP of GPU mining.If the default for ethminer does not work try to specify the OpenCL device with: --opencl-device X where X is 0, 1, 2, etc. When running ethminer with -M (benchmark), you should see something like: To debug the miner: Note hashrate info is not available in geth when GPU mining.Check your hashrate with ethminer, miner.hashrate will always report 0. ethminer can be used in conjunction with eth via rpc or you can use eth to GPU mine by itself:DO NOT FORGET YOUR PASSWORD and BACKUP YOUR KEYSTORE Everything geth persists gets written inside its data directory (except for the PoW Ethash DAG, see note below).The default data directory locations are platform specific: Accounts are stored in the keystore subdirectory.The contents of this directories should be transportable between nodes, platforms, implementations (C++, Go, Python).

To configure the location of the data directory, the --datadir parameter can be specified.See CLI Options for more details.Note: The Ethash DAG is stored at ~/.ethash (Mac/Linux) or ~/AppData/Ethash (Windows) so that it can be reused by all clients.ethereal gem wikipediaYou can store this in a different location by using a symbolic link.ethereum meetupSometimes the internal database formats need updating (for example, when upgrade from before 0.9.20).litecoin live rateThis can be run with the following command (geth should not be otherwise running): Geth's blockchain and state databases can be removed with: This is useful for deleting an old chain and sync'ing to a new one.bitcoin polska forum

It only affects data directories that can be re-created on synchronisation and does not touch the keystore.Export the blockchain in binary format with: Or if you want to back up portions of the chain over time, a first and last block can be specified.bitcoin mining gpu nvidiaFor example, to back up the first epoch: Note that when backing up a partial chain, the file will be appended rather than truncated.best litecoin pool 2015Import binary-format blockchain exports with: /ethereum/wiki/wiki/Blockchain-import-export for more info And finally: DO NOT FORGET YOUR PASSWORD and BACKUP YOUR KEYSTOREmine litecoin with macIt looks like you're new here.bitcoin vs gbp graph

This makes building from source a little less necessary than it used to, which is a good thing.That said, sometimes you might want to be building from source regardless, and the below guide should help you.The below should work on any OSX Mavericks installation, and was successfully tested on a completely new install of OSX Mavericks.Installing Keep in mind it is important that you do not use sudo.Sudoing is not required in most cases (after all, you installed most of your OSX apps without requiring it) and could lead to path issues down the line.Install BrewFirst, install brew.Installing brew will also install the xcode tools that are needed./Homebrew/install/master/install)"Now run brew doctorbrew doctorInstall Go and Dependenciesbrew install gmp goYou no longer need to worry about setting up GOPATH etc... like you did in the previous tutorials.You no longer need to install QT as Mist is now an Electron single page app, and is installed separately.Install Go EthereumFind a nice folder to put go-ethereum in, then: /ethereum/go-ethereum cd go-ethereum make geth /ethereum/go-ethereum/wiki/Command-Line-Options Troubleshooting Note that the develop branch can sometimes have bugs, preventing it from building.
