[quote=gd_barnes;209469]That's an apples to oranges comparison. The scaling is based on the aggregate size range of the numbers, not the n-value. It should sieve n=800K-1.6M base 2 at the same speed as n=100K-200K base 256. For the same reason, it should sieve the file that you're using at the same speed, regardless of whether it's base 2 or 4. After all, it will find the exact same factors either way.[/quote]
Ah, okay, that makes sense. In that case, yeah, I suppose it probably would be better to just convert the master sieve files and do all further work from those.[quote]Didn't I suggest using small #'s like k=10 and n=6 in the "math class" to begin with?[/quote]
Yes, but as I mentioned earlier I came up with a similar idea before I'd seen your post, hence why I went ahead with my own numbers. :smile:

Status Liskovets-Gallot-values
 
Riesel even (k=14361,19401,20049) at n=1136k base 2

Riesel odd (k=103947,154317,163503) at n=979k base 2

I will bring the odd side to the level of the even and test all 6 k-values together then.


k=351134 and 478214 (or 175567 and 239107) at n=1040k base 2.

Just to confirm: This equates to searching n=847K to 1040K for k=351134 and no work for k=478214 since your last status. Is that correct?

Yes, it's correct.

My progress on k=9519 ; New presieved files
 
Hi,

To-day, k = 9519 (Riesel base 2 even n's) is up to n = 1892296 no prime, continuing..

Also, I updated the 18 active files on [url]http://jpenne.free.fr/ConjRus/[/url]

They are now presieved up to 30T

Regards,
Jean

As stated in the "come join us" thread, I have added the Riesel base 2 1st conjecture and Sierp base 2 2nd conjecture even k's testing to this thread and am now testing the 3 remaining Sierp 2nd conjecture even k's. To make it official:

Sierp base 2 even k's 88996, 90646, and 101746 are at n=120K; no primes since n=100K; continuing to n=1M.
