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

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: rhminer.exe -v 2 -r 20 -s http://127.0.0.1:4009 -cpu -cputhreads 1 -extrapayload HelloWorld
Note2: It is not recommended to mine using a laptop.
CPU: I3, I5, Core2, Xeon, Macbook

NOTE: I do not recommend to overclock your cpu. If you do it, it's at your own risk.
note: raw is for raw performance on all hyper-threads. This does not represent real life performance.
To download the screensaver go to release section here https://github.com/polyminer1/rhminer/releases and download PascalCoinScreenSaver.zip
To install PascalCoin ScreenSaver simply right-click on file PascalCoinScreenSaver.scr and click "install" from the menu.
Then you can configure it.
For Laptop users it is STROGLY recommented to set only 1 thread in the scrensaver's config.
To set a mining password open regedit.exe and append your password command line, followed by a space, to the string located here : Computer\HKEY_CURRENT_USER\Software\PascalCoin\ScreenSaver\extra
EX: -pw [email protected]
Dont forget to put a space at the end.
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.
Port is read-only by default. See API.txt for more informations
-apipw Api password for non read-only (miner_restart, miner_reboot, control_gpu, ..).
Default password is empty (read-only mode).
Note: must match ethman password
-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.
NOTE:Background Proces mode will make the console disapear from the desktop and taskbar. 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.
-cputhrottling Slow down mining by internally throttling the cpu.
This is usefull to prevent virtual computer provider throttling vCpu when mining softwares are detected.
Min-Max are 0 and 99.
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 option at your own risk.
Network options:
-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
-dar Disable auto-reconnect on connection lost.
Note : The miner will exit uppon loosing connection.
Debug options:
-testperformance Run performance test for an amount of seconds
-testperformancethreads Amount of threads to use for performance test
With config file:
First use : Edit config.txt and set "s", "su" and desired "cputhreads" or "gputhreads"
Mining with default config.txt : rhminer.exe
Mining with specific config file : rhminer.exe -configfile {config file pathname}
With command line:
Mining solo on cpu : rhminer.exe -v 2 -r 20 -s http://127.0.0.1:4009 -cpu -cputhreads 4 -extrapayload HelloWorld
Mining solo on cpu : rhminer.exe -v 2 -r 20 -s http://127.0.0.1:4009 -cpu -cputhreads 4 -extrapayload HelloWorld
Mining on a pool : rhminer.exe -v 2 -r 20 -s stratum+tcp://somepool.com:1379 -su MyUsername -extrapayload Rig1
Default port is 7111.
Api supports EthMan api format and structure with some limitations.
- At the exception of 'miner_getstat1', the rest of the api needs a pw that match what was passed to rhminer (see -apipw with rhminer and 'Password' field in EthMan)
- For security reasons, method "miner_file" ONLY accept config.txt and config.xml.
- The config file must be under 8K
- The config file must be an rhminer compatible config file containing xml data
- With parameter 'forcerestart' the miner will restart uppon reception of the config file, no mather what was the command line given to rhminer orignialy.
- miner_getstat2 return same as miner_getstat1
- Fan and temperature data are all zero
To change miner's config remotly, using EthMan, you send a config.txt first then send a restart command to the miner.
Just sending empty string will return mining status in json format like that:
{
"infos": [
{
"name": "CPU",
"threads": 2,
"speed": 266,
"accepted": 3,
"rejected": 0,
"temp": 0,
"fan": 0
}
],
"speed": 380,
"accepted": 4,
"rejected": 0,
"failed": 0,
"uptime": 91,
"extrapayload": "",
"stratum.server": "localhost:4109",
"stratum.user": "",
"diff": 0.00000049
}

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.
