Basic help runtime details from https://github.com/ethereum-mining/ethminer

Example to mine with Nvida CUDA enabled: ethminer.exe -RH -U

>ethminer.exe --help
Usage ethminer [OPTIONS]
Options:

Work farming mode:

-F,--farm Put into mining farm mode with the work server at URL (default: http://127.0.0.1:8545)
-FF,-FO, --farm-failover, --stratum-failover Failover getwork/stratum URL (default: disabled)
--farm-retries Number of retries until switch to failover (default: 3)
-S, --stratum Put into stratum mode with the stratum server at host:port
-SF, --stratum-failover Failover stratum server at host:port
-O, --userpass Stratum login credentials
-FO, --failover-userpass Failover stratum login credentials (optional, will use normal credentials when omitted)
--work-timeout reconnect/failover after n seconds of working on the same (stratum) job. Defaults to 180. Don't set lower than max. avg. block time
-SC, --stratum-client Stratum client version. Defaults to 1 (async client). Use 2 to use the new synchronous client.
-SP, --stratum-protocol Choose which stratum protocol to use:
0: official stratum spec: ethpool, ethermine, coinotron, mph, nanopool (default)
1: eth-proxy compatible: dwarfpool, f2pool, nanopool (required for hashrate reporting to work with nanopool)
2: EthereumStratum/1.0.0: nicehash
-RH, --report-hashrate Report current hashrate to pool (please only enable on pools supporting this)
-HWMON Displays gpu temp and fan percent.
-SE, --stratum-email Email address used in eth-proxy (optional)
--farm-recheck Leave n ms between checks for changed work (default: 500). When using stratum, use a high value (i.e. 2000) to get more stable hashrate output

Benchmarking mode:

-M [],--benchmark [] Benchmark for mining and exit; Optionally specify block number to benchmark against specific DAG.
--benchmark-warmup Set the duration of warmup for the benchmark tests (default: 3).
--benchmark-trial Set the duration for each trial for the benchmark tests (default: 3).
--benchmark-trials Set the number of benchmark trials to run (default: 5).
Simulation mode:
-Z [],--simulation [] Mining test mode. Used to validate kernel optimizations. Optionally specify block number.
Mining configuration:
-G,--opencl When mining use the GPU via OpenCL.
-U,--cuda When mining use the GPU via CUDA.
-X,--cuda-opencl Use OpenCL + CUDA in a system with mixed AMD/Nvidia cards. May require setting --opencl-platform 1
--opencl-platform When mining using -G/--opencl use OpenCL platform n (default: 0).
--opencl-device When mining using -G/--opencl use OpenCL device n (default: 0).
--opencl-devices <0 1 ..n> Select which OpenCL devices to mine on. Default is to use all
-t, --mining-threads Limit number of CPU/GPU miners to n (default: use everything available on selected platform)
--list-devices List the detected OpenCL/CUDA devices and exit. Should be combined with -G or -U flag
-L, --dag-load-mode DAG generation mode.
parallel - load DAG on all GPUs at the same time (default)
sequential - load DAG on GPUs one after another. Use this when the miner crashes during DAG generation
single - generate DAG on device n, then copy to other devices
--cl-local-work Set the OpenCL local work size. Default is 128
--cl-global-work Set the OpenCL global work size as a multiple of the local work size. Default is 8192 * 128
--cl-parallel-hash <1 2 ..8> Define how many threads to associate per hash. Default=8
--cuda-block-size Set the CUDA block work size. Default is 128
--cuda-grid-size Set the CUDA grid size. Default is 8192
--cuda-streams Set the number of CUDA streams. Default is 2
--cuda-schedule Set the schedule mode for CUDA threads waiting for CUDA devices to finish work. Default is 'sync'. Possible values are:
auto - Uses a heuristic based on the number of active CUDA contexts in the process C and the number of logical processors in the system P. If C > P, then yield else spin.
spin - Instruct CUDA to actively spin when waiting for results from the device.
yield - Instruct CUDA to yield its thread when waiting for results from the device.
sync - Instruct CUDA to block the CPU thread on a synchronization primitive when waiting for the results from the device.
--cuda-devices <0 1 ..n> Select which CUDA GPUs to mine on. Default is to use all
--cuda-parallel-hash <1 2 ..8> Define how many hashes to calculate in a kernel, can be scaled to achieve better performance. Default=4
--api-port Set the api port, the miner should listen to. Use 0 to disable. Default=0, use negative numbers to run in readonly mode. for example -3333.

General Options:

-v,--verbosity <0 - 9> Set the log verbosity from 0 to 9 (default: 8).
-V,--version Show the version and exit.
-h,--help Show this help message and exit.
