n=1.7M and n=3.322M Twin-Sophie record attempts

When you hold back the big primes, you get the big smileys?

Hmmm...

Anyway, I've done some additional sieving on the n=1.7M file and sieved it to p=1047T (the previous uploaded file was sieved to p=540T). We're at k=178G now, so I've uploaded k=200G - 20T. The file contains 5,709,024 candidates: https://pixeldrain.com/u/LDBtrkJa

Gary, could you replace the k>200G candidates in the server with the candidates in that link? I swear I didn't hold back any primes this time...

I don't know. I think you're removing the rest of the primes! :-)

This is done.

Balancing n=1.7M for future reference:
k<200G: 62,568 candidates sieved to 540T
k=200G-500G: 93,562 candidates sieved to 540T removed from port 12000
k=200G-500G: 86,602 candidates sieved to 1047T added to port 12000

Currently 62,568+86,602=149,170 candidates in port 12000 for k<500G.

Looks good, thanks!

Michael,

What sieving software are you using for this? I'm curious to know how you run the quad sieve for twins and Sophies.

NewPgen have this feature. [select Twin/SG...]

I checked the "Lucky Minus" option on NewPGen, clicked "verify results", and let it run until p=300T or so.

After that, I fed it into TwinGenX to take advantage of the multithreading. IIRC, the header had to be changed a bit since NewPGen and TwinGenX used slightly different formats.
