[QUOTE=paulunderwood;596903]It is imminent. A week or so. :smile:[/QUOTE]

R49081 is actually down to 62k bits and phase 2 has to be run yet, plus a verification of the certificate. So it could be another month. I hope this 18 month run will be tickety-boo on a machine which does not have ECC RAM. Fingers crossed! :smile:

Primo took in phase 2 the hardest points first so I guess it will done this week (or next week).

It is still in phase 1. That should be done within a week. I reckon phase 2 will take a few weeks and the certificate verification about a full day.

Cybertronic 2022-01-10 13:04

Ah ,still phase 1.

Okay , that took a lot of time....maybe left time : (18,6/49)^3.75*18 month~2weeks.

[QUOTE=Batalov;595326]But why? this number has no significance.[/QUOTE]

Why not? I simply want to. :rolleyes: You are fully correct that the amount of work (and brain work) needed for this is near zero.

R49081 is in phase 2. The certification page shows one slight change after more than 3 days. Marcel Martin, Primo author, warned me of the lengthy tasks of phase 2 at ~49k digits. Therefore, expect a further delay for the certification. Let's say another 5 weeks!

On 10th January, I wrote left time Phase 1 will be two weeks. This was correct :smile:.
The most time-ratio Phase1/2 is 4:1 ... so it tooks maybe another 3 or 4 months.

With some trickery I could farm out all of the phase 2 work units to the cloud and run them all in parallel.

Cybertronic 2022-01-24 21:24

I understand ! :smile: ...so to get a valid certificate tooks an extra day.
I remember me to 2010 , where I finished also a certificate parallel under Primo for Windows.

Your guess is about right. The first phase 2 number involved 3 weeks of factoring a degree 206 polynomial at ~49k digits. It nice to see that one finally cracked. So I am thinking the ides of May for the completion and verification of the certificate.
