Sir, We build a Ethereum private chain for one application.We use geth to mine and find the performance is not good. Geth use CPU to mine.So,what method I can use to mine using GPU? Barkely
cpp-ethereum is what I'm using.
$ cpp-ethereum -G -F http://localhost:8545
Make sure that geth is running with an "author" key specified.
But I am not sure it's working, so don't accept this answer until you confirm. I can't find any good docs on cpp-ethereum.
You don't provide much information about your operating system an setup. Anyway, you can quickly test GPU mining by reading the official documentation.
Here, you can find the following example of GPU mining using ethminer:
geth account new // Set-up ethereum account if you do not have one geth --rpc --rpccorsdomain localhost 2>> geth.log & ethminer -G // -G for GPU, -M for benchmark tail -f geth.log
