- Windows binaries https://mega.nz/#F!DqpAjCJQ!Q12a_YRlu_CWA92kIglKug
- Linux binaries https://mega.nz/#F!Dz4ElAwK!gbWbU4OpmEf6YnOCLIKfSQ
To mine locally/solo you'll need the official PascalCoin wallet https://github.com/PascalCoin/PascalCoin/releases
In order to mine locally with rhminer, You need to set a miner name smaller than 26 characters and mine into a private key with encryption type secp256k1
The best way to assure you're mining in a secp256k1 private key is to create one and select it in the option "Always mine with this key".
Do not use the "Use random existing key" option because if one of your key is not a secp256k1 key, the miner will exit when. Plus when there is to much keys in the wallet it gives out errors, sometimes, when submiting nonces
To ensure your miner name is correct, go to Project menu, then Options and set a miner name smaller than 26 characters
To get the number of logical cores, on you system, simply run rhminer with the -completelist option. The last line is the cpu description with the amount of logical core. Ex :
C:\rhminer>rhminer -completelist
rhminer v1.5.2 beta for CPU by polyminer1 (https://github.com/polyminer1/rhminer)
Buid CPU Nov 19 2018 20:04:01
Donations : Pascal account 529692-23
Donations : Bitcoin address 19GfXGpRJfwcHPx2Nf8wHgMps8Eat1o4Jp
CPU : Intel(R) Core(TM) i5-4460 CPU @ 3.20GHz with 4 logical cores
This tells you what is the ideal maximum number of threads for cpu mining (-cputhreads)
Solo mining examples:
For Test net solo mining : rhminer.exe -v 2 -r 20 -s http://127.0.0.1:4109 -cpu -cputhreads 1 -gpu 0 -gputhreads 100 -extrapayload HelloWorld
For Main net solo mining : rhminer.exe -v 2 -r 20 -s http://127.0.0.1:4009 -cpu -cputhreads 1 -gpu 0 -gputhreads 100 -extrapayload HelloWorld
NOTE: remove -gpu 0 -gputhreads 100 if you dont have a gpu
Note2: It is not recommended to mine using a laptop.
- Kepler GTX 700 series, Tesla K40/K80
- Maxwell GTX 900 series, Quadro M series, GTX Titan X
- Pascal GTX 1000 series, Titan Xp, Tesla P40, Tesla P4,GP100/Tesla P100 DGX-1
- Volta GTX 1100 series (GV104), Tesla V100
- Turing GTX 2000 series (GTX RTX, GTX 2060, GTX 2070, GTX 2080)
To mine using gpu you must provide the gpu numbers and the amount of threads for each gpu.
If you only have one gpu, use -gpu 0 and -gputhreads {amount of threads}
If you have more than one gpus, you can see their number by executing the miner with the list option :
C:>rhminer -list
rhminer v0.9 beta for CPU and NVIDIA GPUs by polyminer1 (http://github.com/polyminer1)
NVIDIA CUDA SDK 9.2
Donations : Pascal account 529692-23
Donations : Bitcoin address 19GfXGpRJfwcHPx2Nf8wHgMps8Eat1o4Jp
List of gpus and cpus:
GPU0 : GeForce GTX 1060 3GB
GPU1 : GeForce GTX 1060 3GB
GPU2 : GeForce GTX 950 2GB
CPU : Intel(R) Core(TM) i5-4460 CPU @ 3.20GHz
Then select the ones you want to mine with like this :
rhminer -s http://localhost:4009 -gpu 1,2 -gputhreads 262,102
To find the ideal maximum amount of threads, start with 75% of the memory divided by 8.8.
For a GTX 1060 3GB that is 3000 * 0.75 / 8.8 = 255 threads.
Then run 2 minutes and if everything is stable, raise by say 32 until you get no crashes after 2 min.
To help you in that process, look for the log line that say "CUDA: Using " when the miner starts. It will indicate how much memory you take and how much is left depending on your selected thread count.
ALLWAYS let at lease 150 meg of free memory, for internal OS operations, or you have stability issues.
CPU: I3, I5, Core2, Xeon, Athlon
GPU: GTX 950, GTX 1060, GTX 1070
CUDA: Linux CUDA 9.1, Windows CUDA 9.2

Thre are some limitations on nvidia gpu to consider.
First, the kernel is not 100% stable in all settings. This mean you'll have to experiment to find the stable sweet spot in term of gputhreads. Maximum thread count does not mean maximum speed. Sometimes lower thread count will give you more stability and more speed also.
On multiple gpu rigs, it's NOT recommended to mine CPU at the same time. You'll have more kernel timeout error because the driver will lack cpu time.
Also, it is recommented, on multiple GPU rigs, to run the miner in a loop in a batch file !
On Windows 7/8/10, if you get the missing OpenCL.dll error you need to download it into rhminer's folder. (hint: You can safely get one with the Intel SDK on Intel's opencl website)
General options:
-maxsubmiterrors Stop the miner when a number of consecutive submit errors occured.
Default is 10 consecutive errors.
This is usefull when mining into local wallet.
-extrapayload An extra payload to be added when submiting solution to local wallet.
-apiport Tcp port of the remote api.
Default port is 7111.
Set to 0 to disable server
-worktimeout No new work timeout. Default is 60 seconds
-displayspeedtimeout Display mining speeds every x seconds.
Default is 10
-logfilename Set the name of the log's filename.
Note: the log file will be overwritten every time you start rhminer
-configfile Xml config file containing all config options.
All other command line options are ignored if config file given.
-processpriority On windows only. Set miner's process priority.
0=Background Process, 1=Low Priority, 2=Normal Priority, 3=High Priority.
Default is 3.
WARNING: Changing this value will affect GPU mining.
-v Log verbosity. From 0 to 3.
0 no log, 1 normal log, 2 include warnings. 3 network and silent logs.
Default is 1
-list List all gpu in the system
-completelist Exhaustive list of all devices in the system
-diff Set local difficulyu. ex: -diff 999
-processorsaffinity On windows only. Force miner to only run on selected logical core processors.
ex: -processorsaffinity 0,3 will make the miner run only on logical core #0 and #3.
WARNING: Changing this value will affect GPU mining.
-h Display Help
-help Display Help
-? Display Help
Optimizations options:
-memoryboost This option will enable some memory optimizations that could make the miner slower on some cpu.
Test it with -testperformance before using it.
1 to enable boost. 0 to disable boost.
Enabled, by default, on cpu with hyperthreading.
-sseboost This option will enable some sse4 optimizations.
It could make the miner slower on some cpu.
Test it with -testperformance before using it.
1 to enable SSe4.1 optimizations. 0 to disable.
Disabled by default.
Gpu options:
-cpu Enable the use of CPU to mine.
ex '-cpu -cputhreads 4' will enable mining on cpu while gpu mining.
-cputhreads Number of CPU miner threads when mining with CPU. ex: -cpu -cputhreads 4.
NOTE: adding + before thread count will disable the maximum thread count safety of one thread per core/hyperthread.
Use this at your own risk.
Network options:
-dar Disable auto-reconnect on connection lost.
Note : The miner will exit uppon loosing connection.
-s Stratum/wallet server address:port.
NOTE: You can also use http://address to connect to local wallet.
-su Stratum user
-pw Stratum password
-fo Failover address:port for stratum or local wallet
-fou Failover user for stratum of a local wallet
-fop Failover password for stratum or local wallet
-r Retries connection count for stratum or local wallet
Debug options:
-forcesequentialnonce (For debugging purpose) Force search nonce to be sequential, starting at 0.
WARNING: This will gerate alot of uncle and refused solutions.
-disablecachednoncereuse (For debugging purpose) Disable RandomHash cached nonce reuse.
This will lower hashrate substantially.
-testperformance Run performance test for an amount of seconds.
-testperformancethreads Amount of threads to use for performance test.

Default donation is 1%.
Donation is hardcoded in the binaries downloadable on gitgub. That is to recoup the 6 month it toke to R&D, develop, stabilize and optimize this miner and for the upcoming bug fixes and many upcoming optimizations.
To disable donation download and compile locally, then use the -devfee option with chosen donation percentage. 0 will disable the donation.
