Cuda miner for ergoplatform.com

You can find OpenCL miner at: OpenCL miner

1- Download the miner for desired OS.

2- Run the ErgoStratumProxy executable (Bundled with the miner release)

• In Windows PowerShell:

.\ErgoStratumProxy.exe -s <POOL_ADDRESS> -p <POOL_PORT> -u <WORKER_NAME>

• In linux:

./ErgoStratumProxy_Linux -s <POOL_ADDRESS> -p <POOL_PORT> -u <WORKER_NAME>

3- Run the miner

• If neccessary, edit config.json; set node address to the proxy's address (by default this address is: {"node":"http://127.0.0.1:3000"})

Miner has a HTTP info page located at http://miningnode:36207 (one can change default port by adding -DHTTPAPI_PORT XXXX to Makefile).

It outputs total hashrate, and per-GPU hashrates, power usages and temperatures in JSON format (relies on NVML, can fail if NVML fails - if so, JSON contains error field).

(For Ubuntu 16.04 or 18.04)

To compile you need the following:

1. CUDA Toolkit: see installation guide
2. CUDA Driver compatible with installed Toolkit: see compatibility table
3. libcurl library: to install run

$ apt install libcurl4-openssl-dev

4. OpenSSL 1.0.2 library: to install run

$ apt install libssl-dev

1. Change directory to Autolykos2_NV_Miner/secp256k1
2. Run make

If make completed successfully there will appear an executable Autolykos2_NV_Miner/secp256k1/auto.out and (if not already present) a config file Autolykos2_NV_Miner/secp256k1/config.json with stub contents.

1. Install compatible pair of MS Visual Studio C++ toolchain and CUDA toolkit compatibility table for latest CUDA toolkit
2. Build libcurl from sources with Visual Studio toolchain instruction
3. Download OpenSSL 1.0.2 installer from slproweb.com
4. Edit secp256k1/winbuild.cmd file, change OPENSSL_DIR, LIBCURL_DIR to your libcurl and OpenSSL directories, change CUDA_COMPUTE_ARCH to GPU code architecture you want
5. Find vcvars64.bat script, it should be in VISUAL_STUDIO_INSTALL_DIRECTORY\VC\Auxiliary\Build
6. Run cmd.exe, run vcvars64.bat script, then change dir to secp256k1, then run winbuild.cmd
7. If everything went good, miner.exe should appear in secp256k1 directory
8. If miner.exe can't find nvml.dll, add C:\Program Files\NVIDIA Corporation\NVSMI to your PATH environment variable before running.

• To run the miner you should pass a name of a configuration file [YOUR_CONFIG] as an optional argument
• If the filename is not specified, the miner will try to use Autolykos2_NV_Miner/secp256k1/config.json as a config
• The configuration file must contain json string of the following structure:
  { "node" : "https://127.0.0.1:9052" }

To run the miner on all available CUDA devices type:

$ <YOUR_PATH>/Autolykos2_NV_Miner/secp256k1/auto.out [YOUR_CONFIG]

To choose CUDA devices change and use runner.sh or directly change environment variable CUDA_VISIBLE_DEVICES

• Create a config.json file in miner directory with following structure: { "node" : "https://127.0.0.1:9052" }

To change CUDA devices available to the miner change environment variable CUDA_VISIBLE_DEVICES , for example set CUDA_VISIBLE_DEVICES="0,1"

In order to use this miner with a stratum pool, a stratum proxy is needed.

• Download Ergo Stratum Proxy
• Run proxy
• In the miner's config file set node address to the proxy's address (by default this address is: {"node":"http://127.0.0.1:3000"})

Note that the miner is free to use and we do not charge any fee from what you mine. To support all the work we're doing, we welcome donations from ERGO miners!
