SRBase is a BOINC platform volunteer computing project and needs your help to advance mathematical research.
Why SRBase?
For every base (b) for the forms k*b^n+1 and k*b^n-1, there is a k-value for each form that has been conjectured to be the lowest 'Sierpinski value' (+1 form) or 'Riesel value' (-1 form) that is composite for all values of n >= 1.
Goal
Prove Riesel and Sierpinski conjectures for bases <= 1030 that are not currently being worked on by other projects or efforts.
Methods
The server is famously running on a private computer in a VM and may, or may not, be located in a closet. Recent advancements include updating the application from LLR2 to PRST v10, Multi GPU sieving and Intel® Arc support.
The project is in collaboration with:
- Great Internet Mersenne Prime Search where SRBase's Trial Factoring sieving on GPU is working on the 100-1000M range and have almost completed the 74-75 bit level.
- Mersenne CRUS project
- Work reservation and preparation - http://www.mersenneforum.org/forumdisplay.php?f=81 The link is used for any base reservation. This avoids any duplicate work from other users
- Work creation - All bases over 1M tests (lower ranges) will be split into pieces. Normally there are 2-3 batches, 25-50k, 50-60k, 60-100k. Most of the work is done in Excel
- Check results - merge all results to lresults.txt
- Remove primes from a sievefile with the srfile app
