On 14 October 2016, 19:17:01 UTC, PrimeGrid’s Generalized Fermat Prime Search found the Generalized Fermat mega prime:

44085096^131072+1

The prime is 1,001,953 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 18th for Generalized Fermat primes and 193rd overall.

The discovery was made by Alejandro V. Mena (Alejandro V. Mena) of Mexico using an NVIDIA Tesla K40c in an Intel(R) Xeon(R) CPU E5-2620 v2 @ 2.10GHz with 56GB RAM, running Microsoft Windows 7 Professional. This GPU took about 18 minutes to probable prime (PRP) test with GeneferOCL4. Alejandro is a member of the MENA_COMP_DIE_FI_UNAM team.

The prime was verified on 15 October 2016, 10:27:16 UTC by Michael Mamanakis (Michael Mamanakis) of the United States using an NVIDIA GeForce GTX 1080 in an Intel(R) Xeon(R) CPU E5-1607 v2 @ 3.00GHz with 32GB RAM, running Microsoft Windows 10 Enterprise. This GPU took about 10 minutes to probable prime (PRP) test with GeneferOCL4.

The PRP was confirmed prime by an Intel(R) Core(TM) i5-4670K CPU @ 3.40GHz with 8GB RAM, running Windows 7 Professional. This computer took about 9 hours 14 minutes to complete the primality test using LLR.

Wow...does this include swap RAM or something? 56GB seems crazy.

Unless TheDawgz are mistaken ... It appears that the E5-2620 has a "Max Memory Size (dependent on memory type) of 384 GB"

If I built my computer again today (instead of five years ago), I would probably put 64GB in it instead of 32GB.
