GPU miner for siacoin in go

All available opencl capable GPU's are detected and used in parallel.

Installation from source

  • opencl libraries on the library path
  • gcc
go get




  -url string
        siad host and port (default "localhost:9980")
        for stratum servers, use `stratum+tcp://<host>:<port>`
  -user string
        username, most stratum servers take this in the form [payoutaddress].[rigname]
        This is optional, if solo mining sia, this is not needed
  -I int
        Intensity (default 28)
  -E string
        Exclude GPU's: comma separated list of devicenumbers
        If set, also use the CPU for mining, only GPU's are used by default
  -v    Show version and exit

See what intensity gives you the best hashrate.
