Welcome to PRPNet!

PrimeGrid uses PRPNet to test and prepare new projects. It is also used as a way to offer more varied prime searches that normally will not make it to BOINC.

PRPNet, developed by Mark Rodenkirch, is very similar to BOINC but is used specifically for prime finding. There is no GUI. Instead, it runs in a dos window or Linux terminal. It's very simple to run...just download and unzip the file for your OS, edit a few lines in the prpclient.ini file, and run. You'll be crunching in less than 5 minutes. :)

Manual cobblestones are available.

Max WU time:
Max WU time is determined by the size (digits) of the WU being tested. For example, a WU that's less than 50,000 digits will be given 1 day to complete. A WU greater than 50,000 digits but less than 100,000 digits will be given 2 days to complete.

All ports
50,000 digit : 1 day
100000 digit : 2 days
200000 digit : 3 days
300000 digit : 4 days
400000 digit : 7 days
500000 digit : 14 days

Only GCW13 port
500000 digit : 6 days
600000 digit : 8 days
700000 digit : 10 days

Thank you for participating in PrimeGrid's PRPNet and Best of Luck finding primes. :)

------------------------------------

Instructions for running PRPNet!

1. Download the client for your OS and then extract. You can download the archives here: http://pgllr.mine.nu/PRPNet/
   
2. Run the "#-install-prpclient.bat" ("#-install-prpclient.sh" for Linux) file to build the required folders.
   
   1-single install
   2-dual install
   4-quad install
   8-dual quad install
   
   
3. Open the master_prpclient.ini and modify the following settings:
   
   
   
   • email= This is a REQUIRED field. Enter your email address. E-mail will be sent to this address when a number is found to be PRP. If you wish for your prime to be included in PrimeGrid's Primes Database, please use the same address that you registered with when connecting to PrimeGrid.
     
   • userid= This is a REQUIRED field. Enter your PrimeGrid username here. It will be used by the server to report on stats, etc. and to grant credit. NOTE: If your PrimeGrid userid has a space in it, please use the underscore character _ to replace it. For example: "Prime Time" would become "Prime_Time".
     
   • clientid= This identifies a specific client.
     
   • server= This points to PrimeGrid's PRPNet server from which the client will get work. It is already prepared with default values. Please make adjustments to your preference.
     

   
   Save the master_prpclient.ini file
   

4. Run the "#-update-prpclient-ini.bat" ("#-update-prpclient-ini.sh" for Linux) file to update the prpclient.ini files in all the folders. Mac users will have to make sure they select the proper executable as well.
   
5. Run the "#-start-prpclient.bat" ("#-start-prpclient.sh" for Linux) to start all the clients (the windows will be minimized). The clients will start, communicate with the server, and download WU's based on your server settings in the master_prpclient.ini file.
   
6. The client will automatically select which "primality testing program" (LLR, Phrot, or PFGW) to use on the downloaded WU's. It will continue until interrupted.
   
7. To stop client, press ctrl-C.
   

Additional Information

The configuration of the server section is parsed as follows:

server=<suffix>:<pct>:<workunits>:<server IP>:<port>

• <suffix> - a unique suffix for the server. This is used to distinguish file names that are created for each configured server.
  
• <pct> - the percentage of PRP tests to do from the server.
  
• <workunits> - the number of PRP tests to get from the server. The server also has a limit, so the server will never return more than its limit.
  
• <server IP> - the IP address or name for the server
  
• <port> - the port of the PRPNet server
  

Setting pct to 0 means that the client will only get work from the server if it cannot connect to one of the other configured servers.

Sample settings:

server=PPSE7171:100:2:pgllr.mine.nu:7171
server=PPSE10K:0:20:pgllr.mine.nu:10000
server=SGS:0:1:pgllr.mine.nu:8181

This tells the client to only get work from the Proth Prime Search Extended port 7171. However, you can select other combinations such as 10, 60, 30. This would provide 10% work from PPSE7171, 60% work from PPSE10K, and 30% work from SGS. You can make any combinations you like. Just make sure all numbers add up to 100. :)

NOTE: Using a percentage of 0 will get work from that server only if the client could not connect to any other servers. Therefore, if you don't want work from a particular server, then comment it out and adjust the percentages over the remaining servers.

Finishing the queue and closing the client
When you ctrl-c to close the client, you'll be prompted about what to do.

What should the client do with untested workunits?
1 = Abort all (including current tests)
2 = Report completed tests to server
3 = Nothing

To finish the WU's in cache, upload the results and close the client, change <workunits> to 0. Stop the client and restart for the new setting to take effect.

Please let us know in the PRPNet Discussion thread if you experience any other problems or have any questions.

Below is a copy of the prpclient.ini file. Highlighted in red are the sections you need to add your information.

Highlighted in blue in the server section is where you adjust your project preferences. You can even comment out ports that you don't want to participate in by adding // at the beginning of the line.

// email= is a REQUIRED field. The server will be use this address
// to send you an e-mail when your client discovers a prime.
email=Your@email.here

// userid= is a REQUIRED field that will be used by the server
// to report on stats, etc. without having to reveal the user's
// e-mail address.
userid=User name

// This value differentiates clients using the same e-mail ID
clientid=computername

// server= configures the mix of work to perform across one or more
// servers. It is parsed as follows:
// <suffix>:<pct>:<workunits>:<server IP>:<port>
//
// <suffix> - a unique suffix for the server. This is used to distinguish
// file names that are created for each configured server.
// <pct> - the percentage of PRP tests to do from the server.
// <workunits> - the number of PRP tests to get from the server. The
// server also has a limit, so the server will never return
// more than its limit.
// <server IP> - the IP address or name for the server
// <port> - the port of the PRPNet server, normally 7101
//
// Setting pct to 0 means that the client will only get work from the
// server if it cannot connect to one of the other configured servers.
// Please read the prpnet_servers.txt in this directory for information
// on the latest PRPNet servers.
