Why you make sieving ? We can collect you sieve , send to YOYO and it will be over in ten days at depth you will never reach by yourself.

Dear,

This number I am crunching for a long time on my own...
Thank you for your recommendation, but I have to politely decline your offer

Kind regards,
Valerie

 2020-12-16, 09:08 #87 bur     Aug 2020 79*6581e-4;3*2539e-3 503 Posts I find it really inspiring how long you've been working on this k. I started sieving for Proth k=1281979 some months back, now I'm at around 250T as well, but only for n < 4.1M. So 2 cores produce a factor aprroximately every 2000 s between them. Primality testing will be done using Proth20 on an older GTX7xx GPU, which takes 3.5 h for a = 4M so I'll continue sieving for a while. If I will do this with the same dilligence as you, I'll still be at this k it in 2035... :) Last fiddled with by bur on 2020-12-16 at 09:09
