It's not always bad to be crazy

Just curious, what p value constituted optimal sievedepth on GPU for a 1G range for S3 for n>25K to n=50K? (For those interested, sieving on a CPU had an optimal sievedepth of p=10G for that kind of n-range)

Good luck with your effort, once I get back to this project, hopefully late next year or early 2024, I will have some new monsters, of wich some of those ressources will also be dedicated to clearing some k's from S3 among other conjectures

If the removal rate ends around 46%, per doubling of n, you will remove about 350,000 k values

Looking forward to follow your progress - take care

5e10 seemed to be appropriate, but this is probably a little less than optimal. Took a less than 2 days per range of 1G to sieve to that depth. This leaves about 3.6M tests per range of 1G. Some of my cores will complete PRP testing range of 1G in a little over 30 days. Some will need closer to 50 days.

Attached are the primes for n < 50000 for 20e9 < k < 30e9.

Thanks!

Confirming that you have the range of 6G-123G reserved for S3 n=25K-50K ?

Prefer if they are done in k-range order so there are not so many temporary gaps. :-)

Yes. How I submit the results are dependent upon the computers working on the 10G ranges. Two are fast enough to complete a 10G range in about 5 weeks. The others take about twice that time. My "back of the envelope" estimate is to complete in December based upon the progress I have made.
