Default S128 / S512

For those of you who are interested, I have a list of 1074 candidate n to be tested for S128 and S512, courtesy from John over at PrimeGrid. In this list are n that meet the following criteria:

n (base 2) from 5.33e6 to 6e6
n is for S128 or n is for S512 (in some cases n is for both S128 and S512)
n sieved to 30P (3e16)
n not tested by ProthSearch searchers (many n < 6e6 have been tested, but the range is incomplete)

In other words, if you find a prime with this list, then you have proven either S128, S512, or both S128 and S512. (Assuming that I picked the correct n from the much larger list that I started with.)

If someone here decides to take this on, I recommend 64-bit pfgw over 32-bit llr because it is much faster. If Jean ever releases a 64-bit llr, then all bets are off. I expect that 10 cores could crunch this in about two months.

I will be getting a more current sieve file from John in the coming weeks, but I don't expect it to remove more than 5% or so of the candidates.
