Taking R66 to n-25000.

Yes, I know that I'm a little crazy taking on this large conjecture. I've sieved a small range to 1e7 and I estimate about 25 years on a single core. Fortunately I have multiple cores and as I sieve deeper that number will go down. I just don't know by how much.

I did run into a bug in srsieve2 when starting at p=2 so I sieved to p=1e5 with srsieve. I compared srsieve to srsieve2 in sieving to 1e7. srsieve2 is about 70% faster than srsieve for this base and they have the same results at 1e7. I haven't looked the bug yet. Maybe tomorrow.

I have a sieve file to n=30k that is sieved to 40G. PM me your email address, and I'll send it along.

Hrmm, actually it's ~600MB. Still, PM me if interested, I think I can get it to you anyway.

That would save me time. I suggest you convert to ABCD format using srfile -a, then 7-zip it. My e-mail address can easily be found.

I have the file. I estimate about 3 years (worst case) on a single core).

Sorry, 21 years. I miscalculated. I’ll have a much better estimate by the end of the year.

That's more like it. :-)

VBCurtis (Mike) also sieved to n=30000. I'm going to remove n > 25000 because I don't want to test past n=25000.

VBCurtis · 2019-10-23, 15:47

I'll surely be happy to run 25k to 30k 21 years from now. :-P

K4 S53 at 1.5M

I will continue to 1.6M when sieve is done
Attached res file from 1M4 to 1M5

After one week the estimate is about half, somewhere between 10 and 11 years for a single core. Note that I test each k before going to the next k using the number_primes option so this should be fairly accurate.
