  • Perfect Cuboid 3rd Batch has finished

    Veröffentlicht: Oktober 17, 2018, 12:00am CEST
    If a perfect cuboid exists, its body diagonal exceeds 253. During this batch we were investigating the range of body diagonal from 251 (2'251'799'813'685'248) to 253 (9'007'199'254'740'992). 17'408 face cuboids, 34'816 imaginary cuboids, 156'672 twilight cuboids, a total of 208'896 different cuboids were found with the help of 597'095 workunits. Thanks to everyone who helped to achieve this Great Result. Now we put the subproject on hold for public code review.

    On 26 September 2018, 13:24:01 UTC, PrimeGrid’s Generalized Fermat Prime Search found the Generalized Fermat mega prime: 5828034^262144+1 The prime is 1,773,542 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 9th for Generalized Fermat primes and 66th overall. The discovery was made by Rob Gahan (Robish) of Ireland using an NVIDIA GeForce GTX Titan X in an Intel(R) Core(TM) i7-5930K CPU at 3.50GHz with 32GB RAM, running Windows 10 Core Edition. This GPU took about 25 minutes to probable prime (PRP) test with GeneferOCL3. Rob is a member of the Storm team. The prime was verified on 26 September 2018, 13:51:13 by Jan Kumšta (Honza1616) of the Czech Republic using an NVIDIA GeForce GTX 1080 GPU in an AMD Ryzen 7 1700 CPU with 32GB RAM, running Windows 10 Professional Edition. This GPU took about 18 minutes to probable prime (PRP) test with GeneferOCL3. Jan is a member of the Czech National Team. The PRP was confirmed prime by an Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz with 16GB RAM, running Microsoft Windows 10 Professional. This computer took about 5 hours 57 minutes to complete the primality test using LLR. For more details, please see the official announcement.



  • Genefer 3.3.4 now live

    Veröffentlicht: September 28, 2018, 10:02am CEST
    The latest release of genefer (3.3.4) is now released on BOINC labelled as app version 3.20. The client will download the new app automatically, no action is required on your part unless you are using app_info.xml (if you don't know what this means, don't worry). The new version provides a speed-up of around 10% for AVX and FMA3 transforms for n=21, as well as providing support for multithreading. To enable it, create an app_config.xml file in your BOINC/projects/ directory containing (for 2 threads per task)
           -nt 2
    Any problems or questions, let us know! Please note that as the new release does not affect the OCL code, the GPU app versions remain unchanged.
