On 28 April 2017, 04:22:38 UTC, PrimeGrid’s PPS Mega Prime Search project found the Mega Prime:

805*2^3391818+1

The prime is 1,021,042 digits long and will enter Chris Caldwell's The Largest Known Primes Database ranked 204th overall.

The discovery was made by Reiner Elgetz (reiner) of Germany using an AMD Ryzen 7 1700 with 16GB RAM, running Linux. This computer took about 21 minutes to complete the primality test using LLR with 8 threads. Reiner is a member of the Planet 3DNow! team.

The prime was verified on 28 April 2017 13:44:43 UTC, by William Finn (W.L.F.) of the United States using an Intel(R) Core(TM) i7-5820K CPU @ 3.30GHz with 24GB RAM running Microsoft Windows 10 Professional Edition. This computer took about 1 hour 36 minutes to complete the primality test using LLR.

For more details, please see the official announcement.
