Project Summary
Hunt for giant primes.
Make mathematical history.
primecrunch is a distributed search for large Riesel primes. A focused frontier where your contribution actually matters. Download the lightweight client, donate spare compute, and you could be the one to find the next record-breaking prime.

NOTE: To limit the number od cores that run the application use ./crunch -p 2 in Linux and just crunch.exe -p 2 in Windows to use two cores. This lets you contribute without noticeably impacting other work on the machine.
For all the following you need to be in the folder that crunch is in to run the command.
You can run in the background so you do not need to keep the cmd window open:
Windows: In CMD window: start /B crunch.exe options from below
To stop it after: taskkill /IM crunch.exe /F
Ubuntu/Linux: In a Terminal window: ./crunch &
(The terminal will output a job number and a Process ID (PID) (e.g., [1] 28453).)
To stop later: kill PID Number. like kill 28453

Extended Info for adventurous Users.
when you start the application these are the current options:
Usage of crunch:
-I duration
result reporting interval; drain pending results then pause for this duration, negative to disable (e.g. 30s, 5m; 0 = report immediately)
-U run update once now and exit (no restart loop)
-b int
number of work units to buffer
-c string
sets and alternative working directory (default "C:\\Users\\USER\\.crunch")
-d prevents further downloads but downloaded units will be crunched
-l string
log level: debug, info, warn, error (default "info")
-p int
number of processes to run parallel (default 6)
-r duration
progress report interval; minimum 1m, negative to disable (e.g. 5m, 30s rounds up to 1m) (default 5m0s)
-s string
set an alternate work server (default "https://api.primecrunch.com/v2")
-tui
enable the rich terminal dashboard (default true; set -tui=false to disable) (default true)
-u enable periodic update checks (default true; set -u=false to disable) (default true)
-v prints version and exits
