Some one please verify

Great news - fewer k's for us to PRP now.
New .dat for sieving needed?

I don't see it in Chris Caldwells pending list.
Has anyone submitted it yet?
Has it been double-checked by Dave/Louie anyway?

Congratulations all...
:cheers:

Not necessarily needed, but ~4% speedup according to Mike with the new dat.

It's been verified by a second test with the SB client. Since the Proth test is a proof for these numbers, that rules out everything except coding errors. The probability of a coding error causing a zero residue is roughly 1 in 2^64, so I wouldn't worry about that. Even clobbered memory wouldn't produce a zero residue because there's some post-processing involved. Just in case, though, we are running two more verifications with Woltman's PRP and Yves Gallot's proth.exe, and on different hardware. The PRP run should be done sometime tomorrow I think. Proth.exe will take another 5 days or so.

We notified Caldwell last night, but asked that he wait until the 2 remaining verifications are done before adding it to the database.

Excellente!!
Not that I'm surprised you have it in hand - you're getting the practice! ;)
