Primegrid/en

Deutsch • English

PrimeGrid's primary goal is to bring the excitement of prime finding to the "everyday" computer user. By simply downloading and installing BOINC and attaching to the PrimeGrid project, participants can choose from a variety of prime forms to search. With a little patience, you may find a large or even record breaking prime and enter into Largest Known Primes Database as a Titan! PrimeGrid's secondary goal is to provide relevant educational materials about primes. Additionally, we wish to contribute to the field of mathematics. Lastly, primes play a central role in the cryptographic systems which are used for computer security. Through the study of prime numbers it can be shown how much processing is required to crack an encryption code and thus to determine whether current security schemes are sufficiently secure. PrimeGrid is currently running several sub-projects: 321 Prime Search: searching for mega primes of the form 3·2n±1 Cullen-Woodall Search: searching for mega primes of forms n·2n+1 and n·2n−1 Extended Sierpinski Project: helping to solve the Extended Sierpinski Problem Prime Sierpinski Project: helping Prime Sierpinski Project solve the Prime Sierpinski Problem Proth Prime Search: searching for primes of the form k·2n+1 Seventeen or Bust: helping to solve the Sierpinski Problem Sierpinski/Riesel Base 5 Project: helping to solve the Sierpinski/Riesel Problem with base 5 The Riesel problem: helping to solve the Riesel Problem Generalized Fermat Prime Search: searching for Generalized Fermat primes AP27 Search: Search for Primes with arithmetic progression Primegrid progress Projekt Digits Status Info 321 Prime Search 6.482.811 Range Statistics Cullen prime search 7.478.328 Range Statistics Extended Sierpinski Project 8.157.457 8k left Generalized Cullen/Woodall Prime Search 6.432.819 9k left Prime Sierpinski Problem 9.586.063 7k left Proth Prime Search 1.483.124 Proth Prime Search Extended 585.518 keine Top5000 Primes Seventeen or Bust 12.619.993 5k left Sierpinski Riesel Base 5 LLR 3.365.254 30k/54k left Sierpinski Riesel Base 5 Sieve The Riesel Problem 4.549.608 42k left Woodall prime search 7.215.169 Range Statistics Generalized Fermat Prime Search (n=16) 561.923 Range Statistics keine Top5000 Primes Generalized Fermat Prime Search (n=17) 1.094.164 Range Statistics Generalized Fermat Prime Search (n=18) 1 984 243 Range Statistics Generalized Fermat Prime Search (n=19) 3.628.715 Range Statistics Generalized Fermat Prime Search (n=20) 6.823.620 Range Statistics Generalized Fermat Prime Search (n=21) 12.881.959 Range Statistics Generalized Fermat Prime Search (n=22) 23.233.170 Range Statistics Generalized Fermat Prime Search WR (Do You Feel Lucky?) 25.430.758 Range Statistics World Record Search AP27 Search [erweitert auf AP28] Project Staging Area The PSA was created to research, test, and prepare future projects for PrimeGrid BOINC. It has also expanded to include additional projects that will not enter BOINC. While we attempt to do most of the prep work internally, some efforts are so large that we need the assistance of the community. Sieving Generalized Fermat Number Prime Sieving (paused) There are currently no active sieving projects in the PSA. PRPNet There are currently no active PRPNet projects.
