Po, 17.07.2017 - 12:31
On 15 July 2017, 21:04:54 UTC, PrimeGrid’s Generalized Fermat Prime Search found the Generalized Fermat mega prime: 46776558^131072+1 The prime is 1,005,326 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 24th for Generalized Fermat primes and 240th overall. The discovery was made by Giles Averay-Jones (Dingo) of Australia using an AMD Radeon 7700 series GPU in an Intel(R) Core(TM) i7-4771 CPU at 3.60GHz with 16GB RAM, running Microsoft Windows 10 Core Edition. This GPU took about 41 minutes to probable prime (PRP) test with GeneferOCL2. Giles is a member of the BOINC@AUSTRALIA team. The prime was verified on 15 July 2017, 22:10:39 UTC by Dirk Sellsted (Dirk Sellsted) of Canada using an Nvidia Geforce GTX 1080 Ti GPU in an AMD Ryzen 7 1800X CPU with 32GB RAM, running Microsoft Windows 10 Core Edition. This GPU took about 6 minutes to probable prime (PRP) test with GeneferOCL2. The PRP was confirmed prime by an Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz with 16GB RAM, running Microsoft Windows 7 Ultimate Edition. This computer took about 2 hours 45 minutes to complete the primality test using LLR. For more details, please see the official announcement.
