Why Not? Another PPS-Mega Prime!
On 22 May 2017 21:53:30 UTC, PrimeGrid’s PPS Mega Prime Search project found the Mega Prime:
The prime is 1,022,985 digits long and will enter [Link] Chris Caldwell's The Largest Known Primes Database ranked 202nd overall.
The discovery was made by Randall Scalise ([Link] Randall J. Scalise) of the United States using an Intel(R) Core(TM) i5-4590 @ 3.30GHz with 8GB RAM, running Linux. This computer took about 1 hour 18 minutes to complete the primality test using LLR.
The prime was verified on 24 May 2017 04:17:13 UTC by Luis DeJesus ([Link] lajjr) of the United States using an Intel(R) Core(TM) i7-4510U @ 2.00GHz with 16GB RAM, running Microsoft Windows 10 Core Edition. This computer took about 5 hours 10 minutes to complete the primality test using LLR. Luis is a member of the [Link] Latinos Aqui team.

[wildlife] EXACT v0.25 and v0.26
There was a bug I missed in the EXACT v0.25 client which will cause it to crash from over allocating memory. Please abort any WUs running with this version ASAP so they don't eat up all your machines memory. I really apologize, it ran correctly for my local tests but I had missed a call to convert one of the input filenames to it's proper location in the client.
That being said, v0.26 should be running fine. I made quite a few improvements to the code, so now it should require about 1/4th the memory as the v0.24 client (so the CIFAR work units will now take less memory that the MNIST work units from v0.24 and before). It's also running ~2x faster. That and I upgraded the back propagation algorithm to use batch normalization which also means we'll be getting better results from it. Pretty excited to see how it runs.

Project News 22 may 2017
Due to spammers automatically creating accounts, account creation can and will be disabled at our discretion. Furthermore, this project is reaching its ending phase probably somewere in 2018. This means as long as the software runs and the OS receives updates (EOL 2020), the project will be maintained, but automatic work creation will stop for sure.

Planck contest results
The BOINC Pentathlon is complete, as is our own Planck contest! You can see the results of the Planck contest [Link] here and of the Pentathlon [Link] here. Congratulations to users Mumps[MM], UofS-Computer-Science, and Bryan, and to team SETI.USA (who also won the Pentathlon)! You guys will be added to the list of thank-yous in our paper.
In the end it was a quite exciting race for the 3rd place user spot, Bryan managed to overtake KaptainBlaZzed with only 45 minutes left in the contest last night! Well done to both of you and many thanks to all of the thousands of users and hundreds of teams that contributed. This was far and away the most computing power I've seen at C@H since I've been managing it, and the workunits you computed will greatly help us improve our work. Stay tuned for a future post about these results.

base R964 proven
On 9th of May, Buckey, a member of the team BOINC Confederation found the last prime for base R964.
We have saved the 200-400k range because of the 2 lucky hits in the 100-200k range.
