Why 15 seconds? Tests for R3 at n=75K-80K run about 6-8 secs on a modern I7-9700 with all cores running. Plus there are many tests that will be removed by k's found prime. You could have probably...

That must be a fast siever.


I will have to try a range with srsieve on my new Ryzen 9 that I just got 3 months ago.

Are you sieving only k=35G-36G ?

I posted those sieve files for R3 as fully sieved to P=35G using srsieve. What is your test time at n=80K for R3? I suggest that you use n=80K for a test time. ...

I have Sweety blocked and just delete all of his posts now without even knowing what they say. It makes my job a lot easier.

I will leave this one since it was responded to.

Reb has graciously agreed to have BOINC take over this effort at n=6.65M. At that point we will drop PRPnet1400.

If I was going to split n=2.5K-10K by n-value, if would be in two: n=2.5K-5K and n=5K-10K. Splitting more than that saves so little CPU effort that it is not worth the manual effort to do so.

Optimum sieve depth on those averages P=~15G and they are currently only at P=1G. That is a serious effort for most folks, even for just sieving. Yoyo cannot do them because it's too many k's.
