RSS новости![]() Congratulations to Rob Derrera (TEAM BIGDOG) of the United States, the discoverer of PrimeGrid's 10th Prime Fermat Divisor in the Proth Prime Search project: 131*2^1494099+1 Divides F(1494096). This is the 294th known divisor and the 2nd found in 2012. Rob is a member of the US Navy team. Official announcement soon to come. The Generalized Fermat Prime Search is now out of beta and open to all users. An Nvidia GPU with double precision floating point hardware is required for this project. Also, MacIntel CPU's are supported at the current N=262144 (b^2^18). A wealth of discussion has been gathered during the beta phase. For any issues or questions, please see the Generalized Fermat Prime Search forum. This search will eventually reach N=4194304 (b^2^22) which, if successful, has the potential of discovering the world's largest known prime number. Current testing times at N=262144 are ~1 hr for fast GPU's and ~7 hrs for fast MacIntel CPU's. Best of Luck to everyone! We have recently started a limited doublecheck effort for The Riesel Problem and this has very quickly yielded a prime, which means that the results that we obtained from Riesel Sieve project cannot be trusted 100%. Therefore we have decided to run a full doublecheck effort. We would like to quickly go through the doublecheck ranges and resume our original search, so we would like to ask you to consider redirecting any resources you may have available to The Riesel Problem (TRP) subproject. You can do that by visiting project preferences page. Applications are available for Windows, Linux and Mac. 32bit applications will be sent to 64bit hosts. On 2 Feb 2012, 21:30:55 UTC, PrimeGrid?s The Riesel Problem project eliminated k=162941 by finding the prime: 162941*2^993718-1 The prime is 299,145 digits long and will enter Chris Caldwell's The Largest Known Primes Database ranked 1536th overall. This prime was found while exploring a suspected gap in a previously searched range. This is PrimeGrid's 8th elimination. 56 k's now remain. The discovery was made by Dmitry Domanov (unconnected) of Russia using an Intel Xeon @ 3.60GHz with 2 GB RAM running Windows Server 2003 Enterprise x86. This computer took just over 1 hour 5 minutes to complete the primality test using LLR. Dmitry is a member of Team Russia. For more details, please see the official announcement. Come join us in laid-back competition in tribute to the number 2...the first prime and the only even prime. The prizes are simple colored jerseys . Yellow for the most primes, Green for the highest prime score, and Polk-a-dot for the most primes on 19 Feb. No pressure or stress other than what you put on yourself. :) For more information, please see Tour de Primes 2012.
