On 21 September 2014, 18:43:31 UTC, PrimeGrid’s Sierpinski/Riesel Base 5 Problem project eliminated k=325918 by finding the mega prime: 325918*5^1803339-1 The prime is 1,260,486 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 58th overall. This is the largest known base 5 mega prime. 79 k's now remain in the Riesel Base 5 Problem. The discovery was made by Jörg Meili (meilijo) of Switzerland using an Intel(R) Core(TM) i7-3770K CPU @ 3.50GHz with 8GB RAM running Microsoft Windows 7 Home Premium. This computer took about 20 hours and 51 minutes to complete the primality test using LLR. Jörg is a member of the Aggie the Pew team. The prime was verified on 1 October 2014, 12:57:59 UTC by Yegor Ryabchikov (Yegor001) of Russia using an Intel(R) Core(TM) i5 CPU 760 @ 2.80GHz with 2GB RAM running Microsoft Windows 7 Home Basic. This computer took about 133 hours 16 minutes to complete the primality test using LLR. For more details, please see the official announcement.

Important: hardware and app deprecation for 2015

Hi, With the arrival of Maxwell, we are now supporting 4 generations of hardware, and 6 separate builds of our application on 2 platforms. This is starting to tax our resources, so some rationalisation is required. I therefore propose the following: * Remove support for SM1.3 Geforce 200 series cards contribute rather less than 1% of our capacity and, furthermore, lack hardware features that we want to use in future development work. * Discontinue CUDA 4.2 We need CUDA 6 to properly support the new Maxwell, so I'll be retiring the old CUDA 4.2 build. If you are still receiving version 4.2 WUs, please consider updating your driver 343 or above. These changes will take effect from January 2015 Matt
