S720 is complete to n=100K; 1 prime was found for n=50K-100K shown below; S720 is now a 1ker :smile:; base released.

Prime:
90*720^99529+1

This was a rather remarkable feat. 2 bases in a row that I've tested for n=50K-100K...2 top-5000 primes at n>95K that made both of the bases 1 kers! This last one came with only 34 tests remaining in a 3525 line sieve file. :george:

S748 is complete to n=100K; 1 prime was found for n=50K-100K shown below; S748 is now a 1ker :smile:; base released.

Missed a top-5000 prime by < 30 digits. :no:

This is the 4th consecutive 2k base that I've worked on that has found exactly 1 prime for n=50K-100K leaving 1k bases in all 4 cases.

S991 - Chucking it in

1 Attachment(s)
I probably shouldn't have started with such a large effort there. I have about 150-160 results, but due to the lack of time that I have had to run PFGW, I haven't been able to accomplish much. I think I'll work on some smaller efforts here - sorry about that.

Results attached.

 f1pokerspeed 2012-09-15 21:46

Sorry for double post - reserving R894 - note that I am only taking k = 6. Will go as far as to prove it hopefully.

 rogue 2012-09-15 21:59

Why don't you just continue with S991 and take it to n=50000? We're in no hurry.

 f1pokerspeed 2012-09-15 22:13

In 15 days, I got 160 work units done. There were about 4,000 workunits in the initial batch - at that rate, I'd be done in a year. 25,000 to 50,000 would take about 4 years and two months.

That kind of timeframe is overdoing it for the first reservation I ever make. At the current rate i'm rolling now, I'll be at n=30k for k=6 in the next hour - n=100k in about 12 hours of wall clock time. That's a lot more achievable - I could do that this weekend.

[QUOTE=f1pokerspeed;311760]Sorry for double post - reserving R894 - note that I am only taking k = 6. Will go as far as to prove it hopefully.[/QUOTE]

Be sure and use the sieve file link on the Riesel reservations page. It is sieved for n=25K-100K to P=1T. You can quickly use the srfile program to remove all k's that are not = 6. Note that there are "only" 1074 tests for k=6 for this n-range and sieve depth. On a base of this size sieved that far for just one k, that gives you only about a 13-14% chance of finding a prime by n=100K. Therefore even testing all the way to n=100K where the tests can push a half hour each, the chances are small that you will find a prime.

Just figured I'd give you a heads up on the amount of CPU effort required on large bases here at CRUS.

How many cores do you have? You might want to recheck those calculations for CPU time needed on k=6 for R894. See my previous post.

 f1pokerspeed 2012-09-16 09:43

I have a quad-core laptop and a dual-core desktop. The laptop has AVX, but as a consequence of that it runs out of battery quickly.

I thought that a prime before n=100k might be possible

(NB: I extrapolated on the total testing time for a single core - oh well, it may be a couple of days then. Time to fire up the desktop...

I would suggest leaving the laptop plugged into an outlet and removing the battery. Then you have no worries about battery life. Also, the heat generated by the testing lowers the life of the battery quite a bit.

My estimate for k=6 n=25K-100K was around 15 CPU days. So yeah, 2-3 days if running 6 cores 24x7.

pl_mob are for k that are multiples of b.
pl_remain are k that have no primes for n <= the limit specified in the script
pl_trivial are k for with k*b^n+1 are trivially prime.

Correction and clarification on the last one:

pl_trivial are k with a single trivial prime factor for all n. There are no primes and they are not included in the conjecture.

All that I need for tests n<=25K are the pl_prime and pl_remain files.

Good luck. This base will take a very long time.

Handing this back - unreserved. Sorry about that, but my machines are just too slow for these high bases. I also haven't been able to find much time to do all of the work and sort all of the results files sorted, on multiple cores, etc. etc. I might go for something different, either a different project or a much smaller target that could be done in a few hours to a day or something like that.

What you choose to do depends upon how much involvement you want and what you want to accomplish. If you don't have the time to babysit and want smaller work units, then I suggest the CRUS PRPNet project. If you want even smaller workunits, then I suggest PrimeGrid's PPSelow project.

[QUOTE=rogue;322251]Taking R507 to n=100000.[/QUOTE]

I thought I better check: Do you mean R507 or possibly S507? R507 has 44 k's remaining at n=25K with no available sieve file, which would be a lot of work. S507 has 4 k's remaining at n=50K with a sieve file.
