|GFN-131072 Mega Prime!|
lundi 10 octobre 2016 12:40
On 5 October 2016, 19:10:08 UTC, PrimeGrid’s Generalized Fermat Prime Search found the Generalized Fermat mega prime: 44049878^131072+1 The prime is 1,001,908 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 18th for Generalized Fermat primes and 191st overall. The discovery was made by Alexander Falk (Alexander Falk) of the United States using an NVIDIA GeForce GTX 970 in an Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz with 16GB RAM, running Microsoft Windows 10 Professional. This GPU took about 14 minutes to probable prime (PRP) test with GeneferOCL4. Alexander is a member of The Knights Who Say Ni! team. The PRP was confirmed prime by an Intel(R) Core(TM) i5-4670K CPU @ 3.40GHz with 8GB RAM, running Windows 7 Professional. This computer took about 9 hours 33 minutes to complete the primality test using LLR. For more details, please see the official announcement.

On 8 October 2016, 21:01:14 UTC, PrimeGrid’s PRPNet found the largest known generalized Cullen prime: 682156*79^682156+1 The prime is 1,294,484 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 1st for generalized Generalized Cullen and Generalized Cullen-Woodall primes and 83rd overall. The discovery was made by Franz-Xaver Harvanek (XAVER) of Austria using an Intel(R) Core(TM) i7-5960X CPU @ 3.00GHz with 32GB RAM, running Microsoft Windows 7 Ultimate. This computer took 3 hours and 44 minutes to complete the primality test using LLR. For more details, please see the official announcement.
|Replica database offline...|

The replica database will be offline until we can restore it from the primary database on tuesday (at the earlies). This will result in slowness of the web site and the scheduler.

On 8 October 2016, 05:09:38 UTC, PrimeGrid’s PPS Mega Prime Search project found the Mega Prime: 415*2^3559614+1 The prime is 1,071,554 digits long and will enter Chris Caldwell's The Largest Known Primes Database ranked 134th overall. The discovery was made by Randall Scalise (Randall J. Scalise) of the United States using an Intel(R) Core(TM) i5-4590 CPU @ 3.30GHz with 8GB RAM, running Linux. This computer took about 1 hour 26 minutes to complete the primality test using LLR. The prime was verified on 8 October 2016, 06:43:05 UTC by Alexander Falk (Alexander Falk) of the United States using an Intel(R) Xeon(TM) X5680 CPU @ 3.33GHz with 8GB RAM, running Linux. This computer took about 2 hours 57 minutes to complete the primality test using LLR. Alexander is a member of The Knights Who Say Ni! team. For more details, please see the official announcement.

Предыдущий эксперимент, посвященный подсчету числа диагональных латинских квадратов (ДЛК) порядка 9 успешно завершен, получены искомые оценки для числа нормализованных ДЛК и общего числа ДЛК порядка 9, в настоящее время мы планируем провести их дополнительную проверку, после чего будем публиковать.
В проекте начат небольшой эксперимент, целью которого является анализ применения метода случайных блужданий в задаче поиска кратчайших путей в графе. WU'шки очень короткие, дедлайн 1 день, за неделю думаю все посчитаем, присоединяйтесь!
Last experiment aimed to enumerating diagonal Latin squares (DLS) of order 9 was successfully finished. Now we have values of number of normalized DLS and total number of DLS of order 9. Currently we perform additional verifying, after that results and algorithms will be published.
Now within the project is organized new small experiment aimed to use random walks method at the shortest path problem in graphs with constraints. This experiment has very small WU's and 1 day deadline. After one week I hope it will be finished.

|Website will be down 2016-10-18|
jeudi 6 octobre 2016 16:57
On Tuesday 2016-10-18, at 1330 UTC we will be turning off the einstein Web server front-end for some hardware maintenance. The time corresponds to 1530 CEST and 0930 EDT. This downtime is only for the Web site. The E@H project will continue to run normally. The outage should last about 1 hour.
|New multi-core version 1.05|
jeudi 6 octobre 2016 13:45
The new batch of multicore WU that we have require a new version of ATLAS simulation software so we had to release a new version of the multicore application. The only change is the VM image which unfortunately has grown in size to 2.3GB with the new software.
