Sierp base 3 - mini-drive Ib
 
We have started mini drive Ib for Sierp base 3. The range is k=50M-100M and n=25K-100K.

There were 220 k's remaining to begin with. The drive found 145 k's with primes so there are now 75 k's remaining for this k-range.

This is a low-intensity drive. The files will be relatively small and you should be able to complete them in 2-4 CPU days. As we find primes, like we did with primes that were previously found, we'll remove k's from files for larger n-ranges. Files up to n=100K are fully sieved to P=150G. Many thanks to KEP for the sieving! :-)

I presume that you're verifying the PRPs with PFGW, right?

gd_barnes 2008-11-19 14:05

Max, If we don't hear anything on them being proven, I'll check them later today.

In the mean time, I got an Email of results yesterday from Cedric that clearly shows the range complete so I will show it as such and post more files after elminating some k's.

Hmm...did you forget to run PFGW with the -t option when proving your primes? Because your results only say that your primes are 3-PRP, not proven prime. (3-PRP is, actually, the same thing thing that LLR does on these kinds of numbers.)

I re-ran PFGW on these with the -t command line switch so that it actually proves them prime instead of just doing a PRP test as is the default:
68232896*3^38780+1 is prime! (26.7541s+0.0091s)
72086978*3^38982+1 is prime! (27.0359s+0.0039s)
76479688*3^39859+1 is prime! (27.9304s+0.0026s)
98486582*3^39962+1 is prime! (27.5949s+0.0029s)

(Note: If you're using PFGW to prove Riesel primes, such as those in the Riesel base 3 mini-drive, you'll need to use the -tp command line switch in place of -t.)

I'm still learning all this stuff. Thanks, I'll fix my routines. -t for sierp and -tp for Riesel

I have to admit I've ignored this thread for a long time while I was on my business trip due to the amount of time it takes to update the web pages, remove k's from files, and post files for this base.

I'm getting to it now and will have files posted sometime on Thurs.

I found this prime during a fixed n-search a few months ago, and I didn't know that this was one of the remaining k's left in the base 3 conjecture until I checked this thread yesterday.

I don't know whether or not there are any other primes in the 64K-65K range.

Okay, then, in that case I'll mark it down as found by you but with a special side note indicating that this was found independently of the 64K-65K range in this drive.

Thanks for letting us know about your prime! :smile:

Gary, should we mark this down as found in the 64K-65K range on the reservations table when we get to that point?

Mike,

That was a most astute observation from an old effort! Thanks for sharing it with us.

Do you have any others that we have remaining?


Max,

This is no big deal. Yes, show it as found by Mike as you have done. For the n=60K-65K range, I will just show it as (plus 1 other) like I've done with the Riesel and Sierp base 16 drives where primes are found by other efforts such as when a prime was found for Riesel base-2 odd-n that converted to a Riesel base 16 prime.

Ian,

Please go ahead and include the k in your searching of the n=60K-65K range to see if we find a smaller prime for it. I like to find the smallest prime for each k. Otherwise, we could just search for huge primes n>200K and list those to make us look good. That would be "cheating". lol :smile:

This is bound to happen from time to time. I found a Riesel base 256 prime for k=1478 here that NPLB confirmed for k=739 base 2 two weeks later.

For the very high Riesel base 16 prime for k=13854 shown in the 1st post of that drive, I was doing a search for the Riesel base 2 odd-n conjecture for k=6927. It just so happens that the effort overlapped with bases 4 and 16.

The nature of this effort will overlap a few different other efforts at times, although we attempt to minimize it as much as possible. In other words, if I know someone else is searching something that will encompass all of an effort that we have here, I will show it as reserved by them and not hand it out in the drives. An example is k=443 that Curtis at RPS is working on for base 2 but that overlaps our Riesel base 16. I show it as reserved by him on base 16 so that we don't include it in our drives. Since it's so low weight, he is well past where our drives are at so it's not an issue.

In the case of a fixed-n search like this, there's no way that it can encompass an entire k on any base that we have so there's no way to show it reserved by anyone.

Oh, duh--I had forgotten at the time about how we have already been using the "plus x other" notation for primes found in an individual-k reservation on team-drive bases. Thanks for reminding me. :smile:

One other question, though: When I marked it down I counted it in the "this drive started with x k's, has found x k's with primes, and has x k's remaining" section. Is this correct? Or do we not count it there for non-drive k's?

[/QUOTE]
Unfortunately, no :sad:

I didn't even start from k=1 or anywhere near k=1 for this fixed-n search, so there weren't many base 3 primes found. I was quite surprised that one of them turned out to be a k that CRUS was working on.

gd_barnes 2008-12-27 08:52

More files have been posted with k=54320036 removed...a total of 108 k's remaining.

Ian, if you find it useful, I reposted your reserved file below the reservations with all of the k's removed that you found primes for n=50K-60K. I didn't remove k=54320036 so there are a total of 109 k's remaining in the file.

Yes, we definitely remove the k from that count even though we haven't technically searched up to that range yet. I checked that and you had it correct. The reasoning:

1. Balancing: The # of k's remaining shown in the 1st post must equal the # of k's we started with minus the # of primes found as shown in that post. I use that constantly as a double-check against k's remaining on my web pages that include far more ranges than just this drive.

2. Several other prior efforts: There were a # of top-5000 and other previous base 3 primes that we used to eliminate k's before searching for n>25K. The montra was: Search everything to n=25K and see what remains to attempt to find the lowest primes. For the k's remaining at that point, then use higher primes found from other efforts to eliminate them. In this case, Mike's effort is one of those "other" efforts.

I'm not going to be overly anal about finding the lowest prime on all k's; just most of them. lol Had Mike's prime been n>~100K, I would have had us remove it from the rest of our drive like we, in effect did, for other efforts before the drive started. But since we're close, we may as well see if it is the lowest. The thinking being that we don't want to spend too much extra CPU time to find the lowest prime but a little bit is OK.

Thanks, but I removed the k's myself before I started. (k=54320036 is still in there)

If you want to post the rest of the Drive's pairs, I'll take the whole thing to 100K and thus finish this drive. It should only take me ~ 20 days.

OK, I'll post the rest of the drive in one BIG file sometime late Sunday.

Keep in mind that the testing time at n=100K is double that at n=70K. You have large enough resources that even if you hadn't considered that, I'm sure it won't make much difference.

I already have a fully sieved file from KEP for k=100M-200M for n=25K-100K for this base. So within a few days after you reserve the "BIG" file, I'll start "Mini-drive II - Sierp base 3".

For this next mini-drive, I'm going to run it differently. We'll be searching by k-value but within larger n-ranges and the files will be sorted by k-value. For instance, the first file might contain k=100M-120M for n=25K-40K, the next k=120M-140M for n=25K-40K, etc. for the rest of n=25K-40K. Then we might do the same with 5 different k-ranges for n=40K-55K, 55K-65K, etc.

This will make these drives much easier to administer. I also think that with the files sorted by k, individuals will find it easier to come up with scripts to stop processing after a k finds a prime and start with the next k. So not only will it save administrative time, it should save CPU time also.

Oh, VERY funny he says sarcastically with egg on his face as he bangs his head. :blush::smile:

Yes, I totally forgot to send you the file and you nailed it on the head: I was busy deleting primes posts at NPLB and didn't check any except 1-2 threads at CRUS last night. Look for the file in your Email in the next 10 mins. and I'll show you with the reservation shortly. Sorry about that.

Thanks for the offer to finish things up with this drive! It'll allow us to get the next mini-drive started in the next few days. It can run while you're still working on this one.

To make it official:

Ian is reserving the final range of n=65K-100K for this drive.

Ian, if you can post primes and status every n=5K or 10K as you are progressing with the range, that would help me/Max greatly. I've found it very easy to get way behind quickly here so any time stuff is broken up, it helps.

Thanks again.
