[wildlife] more maintenance issues
I apologize for slow loading on the flights this morning. Our IT staff has been doing some things which I think resulted in this. Looks like things are back up and going thankfully. If I hear any more I'll let you know.

I just put up some new runs. Let me know if you see any issues.
GFN-262144 Mega Prime!
On 16 November 2017, 15:38:45 UTC, PrimeGrid’s Generalized Fermat Prime Search found the Generalized Fermat mega prime:
The prime is 1,718,572 digits long and enters [Link] Chris Caldwell's The Largest Known Primes Database ranked 6th for Generalized Fermat primes and 53rd overall.
The discovery was made by Howard Gordon ([Link] [PST]Howard) of the United Kingdom using a Nvidia GeForce GTX 1060 in an AMD Ryzen 1950X with 32GB RAM, running Microsoft Windows 10 Core Edition. This GPU took about 30 minutes to probable prime (PRP) test with GeneferOCL3. Howard is a member of the [Link] PrimeSearchTeam team.
Double-checker information will be provided once available.
The PRP was confirmed prime by an Intel(R) Core(TM) i5-4670K CPU @ 3.40GHz with 24GB RAM, running Microsoft Windows 7 Professional Edition. This computer took about 10 hours 10 minutes to complete the primality test using multithreaded LLR.

SRBase - 3 years review
The project has passed the third year.
Compared with last years the following process was made:
2014-2015 - 87M WUs processed, 1 base solved, 314 bases unstarted
2015-2016 - 88M WUs processed, 5 bases solved, 297 bases unstarted
2016-2017 - 99M WUs processed, 5 bases solved, 282 bases unstarted
in total - 274M WUs processed, 11 bases solved, 282 bases unstarted
The computing power was beyond the 40TFLOP mark. KEP is still working on a more precise stats overview and will be released maybe in January 2018 so stay tuned.
The next upcoming llr app will have a new gwnum lib with full AMD Ryzen support but I dont know when it will be released.
Due the lack of available sievefiles there are some gaps in the work generation. The remaining primes for these bases are very high, the tests are going over a million. The project cannot handle so many files into one folder thats why they must be splitted into some batches.
The yoyo@home project took over the sieving part for CRUS / SRBase. More and more new sievefiles will be available in the future in a short time period. If you want to help there enable sieving in prefs.
A big thx to the Gridcoin team for the amazing computing power in the past months and of course all the other users / teams spend their power to bring the project forward.
For those who are interested in the public paper for SRBase this is now ready for [Link] download.. I will add a link on the frontpage soon. If you have any questions about it let us discuss this in th...
Pierre de Fermat's Birthday Challenge in 12 hours!
In less than 12 hours, PrimeGrid's three day [Link] Pierre de Fermat's Birthday Challenge will begin. For the first time ever, this challenge will feature the three smallest Generalized Fermat projects, GFN-15, GFN-16, and GFN-17-Low.
Head on over to the the [Link] challenge's forum thread for more information and discussion.
Fill out a survey to help Cosmology@Home
Hi everyone, graduate student Lo Lee and Professor Peter Darch of the University of Illinois (where we got our start back in 2007) are conducting a survey of Cosmology@Home users for their research. If you have a moment, we'd appreciate if you could fill in the survey at [Link] https://illinois.edu/sb/sec/2695704. Your (completely anonymous and confidential) responses may also help us guide the design of Cosmology@Home in the future. Many thanks!
Online questionnaire about citizen science and volunteer computing
Please help Lo Lee, a first-year doctoral student from Library and Information Science at University of Illinois at Urbana-Champaign, by filling in an [Link] online survey about Einstein@Home and BOINC. Lo Lee is doing a project on citizen science that aims to assess to what extent citizen science can be designed as an inclusive online learning environment to embrace volunteer diversity.[Link] read more
Announcing: Fewer Announcements!
In 2018, we are changing our policies regarding announcement of significant prime discoveries. We're raising the bar so that announcements once again are something special and not just "the prime of the week."

Another PPS-Mega Prime!
On 13 November 2017, 00:26:44 UTC, PrimeGrid’s PPS Mega Prime Search project found the Mega Prime:
The prime is 1,036,447 digits long and will enter [Link] Chris Caldwell's The Largest Known Primes Database ranked 208th overall.
The discovery was made by Joshua Charles Campbell ([Link] Warp Zero) of Canada using an Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz with 64GB RAM, running Linux. This computer took about 42 minutes to complete the primality test using multithreaded LLR. Joshua is a member of the [Link] Canada team.
The prime was verified on 13 November 2017, 18:22:32 UTC by Jon Goral ([Link] [KWSN]John Galt 007) of the United States using an Intel(R) Core(TM) i7 940 CPU @ 2.93GHz with 24GB RAM, running Microsoft Windows 10. This computer took about 6 hour 76 minutes to complete the primality test using LLR. Jon is a member of [Link] The Knights Who Say Ni! team.

base S263 cancelled (average app)
I have forgot to change and removed all WUs, 200 WUs were sent out before I noticed that. Please abort all of this batch. Sorry for the trouble.
