Part 2 of the 10²¹ search will be finished, for the most part, today. There are still ~2000 unfinished WUs which can take up to a couple of weeks to complete, depending on individual participants processing them.

Part 3 of the search will look for amicable pairs where the smaller member of the pair has its largest prime factor between 10¹¹ and 10¹⁴:

m=m1*p, 10¹¹ < p < 10¹⁴

There are too many primes larger than 10¹⁴ (all primes up to 5*10¹⁹ need to be checked), so they will require a different approach and a new application when the time comes.

Most of the participants have already started getting part 3 WUs. The new work units will require ~2.5-2.7 GB RAM on CPU, and the same amount of RAM on GPU (for GPU applications), so the minimum requirement for GPUs will be 3 GB RAM.

Right now I don't have an estimate on how long part 3 will take because I haven't accumulated enough statistics yet, and I haven't even finished generating all WUs for part 3.
