On 12 December 2016, 08:33:42 UTC, PrimeGrid’s PPS Mega Prime Search project found the Mega Prime:
733*2^3340464+1

The prime is 1,005,583 digits long and will enter Chris Caldwell's The Largest Known Primes Database ranked 191st overall.

The discovery was made by Randall Scalise (Randall J. Scalise) of the United States using an Intel(R) Core(TM) i5-4590 CPU @ 3.30GHz with 8GB RAM, running Linux. This computer took about 1 hour 14 minutes to complete the primality test using LLR.

The prime was verified on 13 December 2016, 05:33:05 UTC by Rafal Foryszewski (4ys) of Poland using an Intel(R) Pentium(R) Dual CPU E2160 @ 1.80GHz with 2GB RAM, running Microsoft Windows XP Professional. This computer took about 5 Hours 56 minutes to complete the primality test using LLR. Rafal is a member of the BOINC@Poland team.

48 identical computers all constantly running PrimeGrid. No wonder Scalise is finding all of them!
