On 8 June 2023, 01:41:31 UTC, PrimeGrid's Generalized Fermat Prime Search found the Mega Prime: 6339004^524288+1 The prime is 3,566,218 digits long and will enter Chris Caldwell's “The Largest Known Primes Database” ranked 9th for Generalized Fermat primes and 70th overall. The discovery was made by Ken Glennie (xcroc) of Australia using an NVIDIA GeForce GTX 1080 Ti in an Intel(R) Xeon(R) CPU E5-2690 0 @ 2.90GHz with 32GB RAM, running Ubuntu 20.04.5 LTS. This GPU took about 1 hour, 31 minutes to complete the probable prime (PRP) test using Genefer22. Ken Glennie is a member of the SW QLD team. The PRP was confirmed prime on 8 June 2023 by an AMD Ryzen 9 5950X @ 3.4GHz, running Linux Mint. This computer took about 9 hours, 33 minutes to complete the primality test using LLR2. For more details, please see the official announcement.

Hey Everyone,

I'll be shutting the server down for about an hour or two tomorrow at noon EDT (4 PM UTC) to take care of the loads of WUs stuck waiting for validation. They are from leftover Separation WUs trickling in after the project was shut off. Unfortunately I do not think that credit will be given out for these stuck WUs, as they were turned in after the project was shut down, and the validator is not running to give people credit.

N-body WUs will not be affected by this, and all credit will be assigned as per usual for N-body WUs.

Best,
Tom

I am pleased to report that the search over ℚ(√2), also known affectionately as "subfield 3", is now officially 100% complete.

This search has been in the works, off and on, for several years. It goes without saying that this is a major computational achievement. We couldn't have done it without all the volunteers, so I thank you all!

The batch status tables have been updated accordingly with subfield 3 moved to the archives. The results of the search can be found here.
