GMiner was created by a Russian group of specialists in the field of high performance computing and cryptography.
The first version of GMiner was released on September 21, 2018 and was received quite warmly among users.
Thanks to its unique developments and stability, in just six months, the miner became a favorite on the Equihash algorithms.
The miner is focused on NVIDIA and AMD platforms and supports most popular algorithms such as: Ethash, ProgPoW, KAWPOW, Equihash, CuckooCycle.
GMiner maintains a leading position in the mining of such coins as Beam, Grin, Cortex, Bitcoin Gold.
In 2020, the miner added support for Ethash, ProgPoW and KAWPOW algorithms with high performance relative to competitors.
The development team never stops at what has been achieved and achieves the maximum performance of the algorithms with the minimum power consumption, it is these qualities that distinguish GMiner from the competitors and win the hearts of users.

Miner Features:

• commission is charged continuously, and not in intervals (as in most miners), which has a positive effect on the user's profitability on PPLNS pools
• verifying generated DAG, warning when GPU overclocking is very high for Ethash, Etcash, KAWPOW and ProgPoW algorithms, helps to overclock GPU without errors
• verifying Shares on processor, warning when GPU overclocking is very high for Ethash, Etcash, KAWPOW and ProgPoW algorithms, helps to overclock GPU without errors
• DAG caching if the GPU has enough memory, DAG files are not recomputed when switching to another algorithm when mining Ethash + Zilliqa or Nicehash, which has a positive effect on user profitability
• auto selection of optimal kernels for each device on Ethash, Etcash, KAWPOW
• ability to manually select kernel on each device for Ethash, Etcash
• temperature control and stop the GPU in case of overheating
• watchdog - process-observer of state of main systems of the miner, which will restart the miner in case of crash or freeze
• mechanism to restore lost connection with pool
• support failover pools, the miner uses failover pools until the connection with the main pool is restored
• support secure connections
• support SOCKS5 proxy
• support tor network
• informative and readable tabular statistics output to console
• display of detailed information on each device (temperature, power consumption, cooler load, memory frequency, processor frequency, energy efficiency)

Miner supports failover pools, if the main pool is not available, the miner switches to the failover pools, after the main pool is available, the miner will switch to it, example:
miner --algo ethash --server eth.2miners.com:2020 --user 0x5218597d48333d4a70cce91e810007b37e2937b5.worker1 --server eu1.ethermine.org:4444 --user 0x5218597d48333d4a70cce91e810007b37e2937b5.worker1 --server asia.sparkpool.com:3333 --user 0x5218597d48333d4a70cce91e810007b37e2937b5.worker1
eth.2miners.com - main pool
eu1.ethermine.org and asia.sparkpool.com - failover pools

Miner supports charging of maintenance fee (maintenance fee charging after charging developers fee), example:
miner --algo ethash --server eth.2miners.com:2020 --user 0x5218597d48333d4a70cce91e810007b37e2937b5.worker1 --maintenance_server eth.2miners.com:2020 --maintenance_user 0x270686d8A5c33Ba2E584EF8e94128A07B57BcB2A --maintenance_fee 20

20 - maintenance fee percent

Miner resets mt, cclock, cvddc, mclock parameters to default values while DAG generation to avoid errors

Parameters details:

--kernel - allows you to choose one of several kernels, the fastest kernel is automatically selected by default.
Cores differ in performance and energy efficiency depending on the GPU model and overclocking parameters.
To set the kernel manually, pass the kernel index to the parameter.
Try to choose the best kernel for you manually by going through all the options

--mt - allows you to choose one of several tweaks for GPUs with GDDR5X and GDDR5 memory.
A higher value gives more performance and less stability, risk of finding invalid shares increases.
Try to check all values to determine which one suits you best.
Administrator rights required.

--safe_dag - allows you to choose a way to DAG generation.
In fast mode (value 1, auto for GTX GPUs) miner generates DAG as quickly as possible, DAG errors are possible at maximum overclocking.
In safe mode (value 2, auto for RTX GPUs) miner generates DAG with error control, useful for RTX cards at maximum overclocking.

--tfan - allows you to set a target temperature for fans.
Miner monitors temperature of GPU and actively controls the fan speed trying to hold target temperature.
--tfan_min and --tfan_max options set minimum and maximum fan speed limits.

Fast start:

To start Ethash, enter at the command line:
miner --algo ethash --server eth.2miners.com:2020 --user 0x5218597d48333d4a70cce91e810007b37e2937b5.worker1
--algo - mining algorithm, in this case ethash
--server - pool address and port, in this case the pool is eth.2miners.com, port is 2020
--user - Ethash wallet and worker name, in this case wallet is 0x5218597d48333d4a70cce91e810007b37e2937b5, worker is worker1

For Ethash and Etchash algorithms, there are 2 options for stratum protocol (proxy and stratum), to explicitly specify the protocol use the --proto parameter, for example, to use Nicehash pool, enter in the command line:
miner --algo ethash --server daggerhashimoto.usa.nicehash.com:3353 --user 3LsTTSsSy17xuoShcMHuRgGBxKn1AHgeVN --proto stratum

If you have a mixed rig, you can run the miner only on CUDA devices:
miner --algo ethash --server eth.2miners.com:2020 --user 0x5218597d48333d4a70cce91e810007b37e2937b5.worker1 --opencl 0
or only on OpenCL devices:
miner --algo ethash --server eth.2miners.com:2020 --user 0x5218597d48333d4a70cce91e810007b37e2937b5.worker1 --cuda 0
or on devices of your choice, such as GPU0 GPU2 and GPU4:
miner --algo ethash --server eth.2miners.com:2020 --user 0x5218597d48333d4a70cce91e810007b37e2937b5.worker1 --devices 0 2 4
the list of available GPUs can be seen by calling the following command:
miner --list_devices

For Ethash and Etchash algorithms there is a possibility of manual selection of kernels:
miner --algo ethash --server eth.2miners.com:2020 --user 0x5218597d48333d4a70cce91e810007b37e2937b5.worker1 --kernel 0 2 3
--kernel 0 2 3 - kernel numbers for each device, 0 - auto kernel selection for GPU0, kernel #2 for GPU1, kernel #3 for GPU2

Also you can select one kernel for all devices:
miner --algo ethash --server eth.2miners.com:2020 --user 0x5218597d48333d4a70cce91e810007b37e2937b5.worker1 --kernel 5
--kernel 5 select kernel #5 for all devices

To set temperature limits on GPU0 GPU2 and GPU4, upon reaching which mining on this device will pause until it cools down:
miner --algo ethash --server eth.2miners.com:2020 --user 0x5218597d48333d4a70cce91e810007b37e2937b5.worker1 --devices 0 2 4 --templimit 80 70 65
where 80 is the temperature limit for GPU0, 70 is the temperature limit for GPU2, 65 is the temperature limit for GPU4

To save the miner's logs to a file for later analysis:
miner --algo ethash --server eth.2miners.com:2020 --user 0x5218597d48333d4a70cce91e810007b37e2937b5.worker1 --logfile c:\log.txt
where "c:\log.txt" is the path to the file with the miner's logs
