Autolykos CUDA-miner For Pool

this version is for pool

Pool Maintainer Prerequisites

change the char *poolStr to your pool's bip39 key.

then compile and distribute to your mining friends.

Prerequisites (Linux)

(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

Install (Linux)

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

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

Test (Linux)

1. Change directory to autolykos/secp256k1
2. Run make test

If make completed successfully there will appear a test executable autolykos/secp256k1/test.out.

Install (Windows 64-bit)

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/buildwin.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 buildwin.cmd
7. If everything went good, miner.exe should appear in secp256k1 directory

Run (Linux)

• 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 autolykos/secp256k1/config.json as a config
• The configuration file must contain json string of the following structure:
  { "node" : "http://POOL_ADDRESS:PORT/your_wallet_address_not_privatekey", "keepPrehash" : false }

If your seed mnemonic string is protected by password, add option "mnemonicPass": "yourpassword" to your configuration.

The mode of execution with keepPrehash option:

1. true -- enable total unfinalized prehashes array (5GiB) reusage. ( Should only be used if your CUDA devices have >= 8GiB memory)
2. false -- prehash recalculation for each block. (For CUDA devices with >= 3GiB memory)

To run the miner on all available CUDA devices type:

 <YOUR_PATH>/autolykos/secp256k1/auto.out [YOUR_CONFIG]

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

Run (Windows 64-bit)

• Create a config.json file in miner directory with following structure: { "mnemonic" : "mnemonicstring", "node" : "https://127.0.0.1", "keepPrehash" : false }

If your seed mnemonic string is protected by password, add option "mnemonicPass": "yourpassword" to your configuration.

The mode of execution with keepPrehash option:

1. true -- enable total unfinalized prehashes array (5GiB) reusage. ( Should only be used if your CUDA devices have >= 8GiB memory)
2. false -- prehash recalculation for each block. (For CUDA devices with >= 3GiB memory)

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

Mnemonic and public key generation

• Run auto.out -G

It will generate a BIP39 192 bit entropy mnemonic phrase and public key for you.
