Message 139463 - Posted: 6 Apr 2020 | 17:21:54 UTC

The Sierpiński problem already leads to three subprojects here at PrimeGrid: Seventeen or Bust (SOB), the Prime Sierpiński Problem (PSP) and the Extended Sierpiński Problem (ESP).

Here is an idea for a similar subproject. Recall that a prime k*2^n + 1 is called a Proth prime only if 2^n > k. So why not try, for each k, to find an n that gives a Proth prime?

So I require n > log2(k).

To give an example of a multiplier that may need to be included in such a new subproject, consider k=12743. Note that 12743 is not a Sierpiński number because n=9 gives the prime:

12743*2^9 + 1

But 12743*2^9 + 1 is not a real Proth prime because 2^9 < 12743. The traditional Sierpiński projects have not considered k=12743 because a prime is known. But I want a prime with n > log2(12743) ≈ 13.6.

What I propose is to find the first real Proth prime for k=12743 and for other values of k for which it is not obvious. Let us consider k up to 78557 (the first k known not to produce any (Proth) primes).

If such a "Proth Sierpiński problem" is interesting to people, the first thing we should do is to come up with a list of k to cover. An interesting k has a small prime with 2^n < k, but no "easy" or known prime (in PrimeGrid's or the Prime Pages' databases) with 2^n > k.

I found some Proth primes for k=12743:
12743*2^41205+1
12743*2^49113+1

My next candidate is k=22249.

I quickly sieved and tested 22249*2^n+1 for n up to 100,000 and didn't find any primes. This one might be a little more tricky.

Edit: I'm going to try up to n = 250,000 and see if I can find anything.

It may end up with same concrete wall as SoB currently is.

I have a list of all 'n' for SoB project numbers (also there is a oeis sequence A046067 for first 5000, but it had wrong entry for 7413, afair).

33990 candiates are primes with, roughly, n <= 17. I didn't compared log2(n) for each one so it'll drop a bit.

Next, you can exclude candidates wihere primes were found by PPS/PPSE search.

I quickly sieved and tested 22249*2^n+1 for n up to 100,000 and didn't find any primes. This one might be a little more tricky.

Edit: I'm going to try up to n = 250,000 and see if I can find anything.

Don't use newpgen, it has a bug and removes small n (when k*2^n+1 = p). Use srsieve + sr2sieve, then remove only necessary small candidates manually.

22249^2+1 is prime.

22249^2+1 is prime.

Any number small enough to be removed by NewPGen from that issue was going to be too small for the 2^n > k requirement anyway - or would be trivial to check otherwise.

I sieved to about p = 3.5 billion before beginning the prime searching; log2(p) is about 31.7. I confirmed using Mathematica that 22249 * 2 ^ n + 1 is not prime for any n ≤ 50 (except 2) - so NewPGen didn't inappropriately remove any candidates.

And yes, 22249 * 2^2 + 1 is prime but 2 ^ 2 < 22249.

Not true. I've calculated this limit some time ago. Don't remember exact numbers, but you'll have a gap to... 60 or may be 80, depending on sieving depth (max p).

or would be trivial to check otherwise.

Yes, it could be simple testing of all n up to 100, even without sieving. May be it'll take just one second per k, but it must be done.

Note that I tested all n up to 100,000 with k=22249, with PFGW with an ABC2 file, and using -f from the command line (-f was the only kind of sieving). So I am sure we did not miss anything with this k.

I am in the process of producing a gross list of relevant k. Expect to see it here later today.

Do post any new primes with these k in this thread.

If I did everything correctly, I have already checked up to n = 100,000 in each.

If I did it correctly, the list is complete. I.e. it contains all odd k for which an n with 0 < n < log2(k) does exist, but an n with log2(k) < n < 100,000 does not exist (and also no n > 100,000 is published edit: not needed).

Multipliers k for which no n is known at all, are covered in the "classical" Sierpiński problem (so Seventeen or Bust).

Great.

I should also announce what I am doing. I am running a somewhat slow PFGW test of all the k in the list, from n = 100,000 and up. It is currently near n = 129,700 and has not found other primes than the one I "published" above.

At this time, PrimeGrid has no interest in putting this project on BOINC or PRPNet. We may reconsider this later at some point, but that would be at LEAST a year or more down the road. The admin team has a few other things on our plate that are higher priority than this currently, such as bringing back GFN Sieving, WW, and more. You're welcome to coordinate the effort here, but that will be all of PrimeGrid's involvement for now.

Clear.

Well we should make a repo for all the reservations here if anyone's interested. Maybe a github project?

I checked 150k-160k overnight (assuming that someone else would go up to 150k), nothing new. Starting 160k-170k.

Your assumption was right. My search is past 150k. So with your result every k is searched to 160k (soon 170k).

numbermaniac has taken 22249 and 68633 to 250k.

Kellen is running far with 76877 and 50777.

With 13 remaining k's, based on estimates of their weights from here, we would need to multiply the current n by about 30000 to have a 50% chance of eliminating them all. (Currently this means n ~ 5B, but the 30000x multiplier will stay true until we find another prime.) The lowest-weight k's are 76877 and 23971, so the luck we get (or don't get) with those k's will be the main determiner of whether it's feasible to finish this project.

Full table of weights, calculated with P=500K and N=5M:

k weight --------------- 22249 0.3253 23971 0.1180 28831 0.2716 44243 0.2793 45323 0.3053 50777 0.1900 50873 0.4702 54953 0.2429 57377 0.1988 68221 0.3995 68633 0.3066 71657 0.3850 76877 0.0929

Looks like I picked a good one with 76877. Testing up to n=1M is very nearly complete and nothing so far. Testing to n=3M begins tomorrow, along with sieving to n=10M (as there is a good chance we will need it and that sieve will take some time). Fingers crossed!

I should also mention that 57377 will be tested to n=1M in a day or two. Somehow I missed that one when picking the k's with the most 7's :)

Just FYI, my testing between 150K and 170K included all remaining k's (I didn't exclude those that had been reserved), so you can skip ahead to 170K if you want. Of course this is a negligible amount of work compared to going up to 1.5M.

Kellen, right now it's more important to eliminate k's at low n's than to go deep on a single k. I'd advise against going past n=1M solo.

Oooops! In that case then I will also grab, and test to 1M, 45,323 and 50,873.

There are a handful (20ish) candidates left for 76,877 up to 1M and no primes. I will finish those last few then stop. All residues and sieve files are saved if anyone needs/wants them (this goes for all k's).

I hear ya on that whole keeping-track thing! I have stacks of paper on my desk for the GFN 1-12 projects :)

And you are correct I am taking 45323, 50777, 50873 and 76877 to 1M. 76,877 is complete to 1M and 50,777 is almost there and the other two will take a bit more time, but should be there by the end of day Saturday.

At that time I will see what is left on the list and either start on one that I haven't done or start taking the ones listed above to higher n values, unless there is some other methodology you would like me to use; just let me know :)

@ everyone:

You can take this as a word of advice :)

I really like the idea of this project, but as a conjecture guy (11 years running almost just conjectures) I have learned how important it is to get things done correct from the very first test untill the last test/needed prime is found.

So here is what I suggest that you all do.

2. Test everything to n=1M
3. At n=1M, Jeppe checks all results and compare to the sievefile to make sure no n's is untested for remaining k's
4. Once everything for the k's remaining at n=1M is verified as fully first time checked, start sieving
5. Sieve from n=1 to n=10M up untill it takes 70% of the time it takes to complete a test at nMax, to remove a candidate by finding a factor. Example given: Test at nMax=10000 CPU seconds, factorremovalrate=7000 CPU seconds per factor, means that you are at optimal sievedepth
6. Do an unformal doublecheck, by running everything that remains from n=1. Make reservationfiles covering sets of 1000, 5000 or 10000 tests. The users can reserve a range here and download the matching workfile, from a googledrive account made just for this project
7 Test happily towards n=10M and verify as ranges completes, that actually all n has a result and therefor nothing is missed

Just my 2 cents, good luck on this "problem" - in case you need advise or have questions, feel free to ask and I will share my experience and help you the best I can :)

Excellent post by KEP.

I'd like to add that there's no need to rush testing after n=1M. You need to do it correctly, so that nobody has any doubt that the range is searched thoroughly. Also, new testing schemes may help to speed up the process.

Thank you very much for the good advice. We may want to double-check ranges of tiny n at a later point (for those k that survive, at least).

I am in the process of taking 54953 and 71657 near n = 300k.

dannyridel, can I ask you about the status of your multiplier, 44243? What program/method are you using to test it, and how far have you come?

Hi, I'm near 200k for k=44243, and I am using LLR multithreaded. If I'm allowed, I'll continue to 1.5M, because at my rate every other k will be at 1M when I reach that. I've already sieved to 2*10^11 using sr1sieve.

Thank you everyone :)

I may add, that a good way to test that everything was in fact tested, is to use create a bogus factorfile, with the tests that you have a residue for. On SR383, I do as follows:

1. Create a list of k*383^n+/-1 that has a test, example given: 128*383^200000+1
2. In a spreadsheet, put this code in column 1 "3333333333333333333333 | " and in column 2 "k*383^n+/-1"
3. Copy both columns to a notepad and insert
4. Remove tabseperation
5. Save in a DC folder as anygivenname.txt
6. Copy srsieve.out to the DC folder
7. Run srfile in DC folder using shift+right click and push Open Commandwindow
8. Run following command: srfile -k anygivenname.txt srsieve.out - this will remove the completed tests from srsieve.out
9. Run following command: srfile -G srsieve.out - this will create a version of base 383 tests remaining untested.
10. Check that the highest n for each k in your resultfile is in fact lower than the smallest remaining n you have for each k --> dependant how clean your search is, then you may in step 9 want to run following command: srfile -g srsieve.out, then you will easier be able to compare the resultfiles with the n remaining and if for each k remaining, n remaining is higher than highest n for each k in your bogus factorfile, then you will know that nothing has been missed. You will not know if the quality of the test is good or bad, you will ONLY KNOW that nothing was missed.

Hope this made sense and please remember to work on a copy of your original srsieve.out file, else you may loose a lot of work. Also remember, that unless you are determined to find the absolut smallest n that makes a prime (the first n) then there is no need to check the already primed k's.

It is a good question. I guess you can try that. Or ask Yves Gallot if it is appropriate.

On Discord, Pavel Atnashev suggested we use his version of LLR in which you can say -oGerbicz=1 to get a Gerbicz check. That should catch problems with hardware errors (which might otherwise incorrectly skip a prime).

50,777 is now tested to 1M, and no primes were found.
45,323 is at ~525K and 50,873 is at ~640K. No primes for those ones either yet. As those two have a lot of candidates they will take a bit longer to test than I had originally anticipated, but I'll split the upper ranges onto a few computers tomorrow or Sunday to speed things up with the goal of completing them both to 1M by end-of-day Monday :)

Major storm forecast for tomorrow and the power will likely go out, but if it doesn't, or if the outage is short, these will likely be finished tomorrow night. Tuesday night is a certainty, barring some electrical grid catastrophe :)

I stroke luck!!!!
On this wonderful day, I eliminated k=44243 from this problem with the prime:
44243*2^440969+1 is prime! (132750 decimal digits) Time: 123.927 sec.

I am going to USAP about an hour later....will this be a sign of good luck today.....

Dear all,

Before we go to exponents n > 1'000'000, maybe we should double check our work for the candidates not yet eliminated? What are your thoughts?

There is one candidate which is especially interesting. The heaviest of all our seventeen original k candidates, with weight 0.4702, has found no primes for n between 15.6 and 1,000,000. Maybe someone is going to post here the Poisson-ish distribution of the numbers of primes expected in that n range (i.e. Probability(0 primes) = ###, Probability(1 prime) = ###, … etc.; average number of primes, etc.)?

Maybe it is just a coincidence? Maybe I did a mistake when I included it in the list? Maybe someone who tested it did a mistake, or had an unnoticed hardware glitch? Maybe this k has some property not reflected in the way we estimate its weight?

Yes, DC is good. I will take them up to 250K for a start.

For n>1000000 I suggest to use new LLR2-testing project on my server.

Coincidence? I think so. The last assumption seems a bit unlikely, but I think someone out there has a suggestion.

It is a good idea doing a doublecheck. This can be done, without removing too many ressources from sieving.

There is nothing special to any of your k's. I've tried all of them, using srsieve and none of them came back with algebraric factors. They simply just are normal base 2 k's with various kind of factorisazion rates.

If we look at the removal rate, it is also pretty desent. In average going from n=100K to n=800K (might not be complete to n=800K) you have a removal rate of ~25.1% of the k's being primed, each time you double your testrange. At n=100K you had 17 k's remaining, at n=200K you had 13 k's remaining, at n=400K you had 11 k's remaining and at n=800K you for now have 7 k's remaining. In average that gives a removal rate of ~25.1% over the entire range from n=100K to n=800K.

There could be a hardware glitch, but most likely, nothing has been missed. Nothing can be derived from looking at the weight. To give you an example, I have a lowest weight and a heaviest weight k on S383. K=128, has from 537500 1140 candidates remaining and k=186 has 15658 candidates remaining below n=1M. The low weight candidate accounts for 0.425% of candidates remaining and the heavy weight accounts for 5.839% of candidates remaining. So as you can see, despite being 13.735 times the weight of k=128, k=186 still remains at n=350K.

The best way to assertain wether something were in fact missed, is to do full double check, however does the ressources to that not excist, then as the removal rate "normalize" you should start using the average percentage of k's being primed each time n doubles, to get an idea wether something was missed.

If you ask me, there is nothing more than regular "normal" k behaviour at play.

If you have in fact tested to n=800K, you can expect to have these amount of k's remaining at following n:

n=800K 7 k remaining
n=1.6M 5.243 k remaining
n=3.2 3.927007 k remaining
n=6.4 2.941328243 k remaining
n=12.8 2.203054854 k remaining
n=25.6 1.6500880857 k remaining
n=51.2 1.2359159762 k remaining

So with a little luck, you might actually proove this "problem" at around n=50M and you should have no more than 3 k's remaining at n=10M.

If you choose to sieve from n=1000001 to n=10000000 you will have more or less these amount of candidates remaining at following sievedepth:

p=100M 57122 (FACT)
p=1G 51929 (calculated by saying previous steps of candidates remaining div 11 x 10)
p=10G 47208 (calculated by saying previous steps of candidates remaining div 11 x 10)
p=100G 42916 (calculated by saying previous steps of candidates remaining div 11 x 10)
p=1T 39014 (calculated by saying previous steps of candidates remaining div 11 x 10)
p=10T 35467 (calculated by saying previous steps of candidates remaining div 11 x 10)
p=100T 32242 (calculated by saying previous steps of candidates remaining div 11 x 10)
p=1P 29310 (calculated by saying previous steps of candidates remaining div 11 x 10)

Sieving should be fast and 1P may be too high a sievevalue.

This is DC of PrpNet k=121 work (currently) and k=27 (planned if we run out of k=121 candidates)

To load this problem, DC of small ranges and sieving must be done first. I'm working on sieve file up to n=10M.

Here's the real bad news though:
my sieve file for k=68633 is corrupted, so I can't search until another 5hrs of sieving, I'm going to abandon this K value.

So 68633 from 250k and up is available now.

I think I heard above (a couple of days ago), stream offering to run this project on his BOINC server, "private server". For n > 1'000'000.

I find that a generous and attractive offer. In my opinion, we should do that.

I am running (slowly) with 71657. It is currently near n = 688'000; no prime yet.

@JeppeSN Could you update the table with DC status? Range and how many passes were made.

I've tested everything up to 500M and now thinking should I go further to 1M myself or just collect existing one pass 500K-1M residues and load them to my server as a part of LLR2 testing.

Anyway, I'm sieving remaining candidates so future work could be distributed from my server.

These are now finished, but no primes found here either. I have sent my residues to Stream for the DC effort :)

You do not attract much luck, Kellen. With all the tests you have run, I think you have discovered only one prime in this "project". /JeppeSN

Lol! Yep! My luck with these k values has definitely been quite low. Hopefully I'll get 1 or 2 when we go over 1M :)

Well if this problem does have primes beyond 1M you'll definitely get at least one! Just look at the sheer computing power of yours!

k = 71657 is also complete to 1'000'000 now.

Should I send the residues for 500'000 to 1'000'000 to stream? If yes, how (send me private message if needed)?

Few small candidates were loaded as part of LLR2 testing, and...

71657*2^1146175+1 is prime! (345038 decimal digits) Time : 736.093 sec.

Congratulations to Pavel!

Note: this is not a "official" search yet. LLR2 testing may test any numbers which I need to. It may have tests from this problem, may have other types of tests, or may run of work completely. Only small candidates (less then 448674 digits, current T5K margin) coulld be loaded now. Also more sieving is required for future tests.

On the server everything up to 1,5M was tested.

The project is currently paused. To continue, two things must be done first:

1) more sieving (currently in progress);
2) new LLR with new amazing capabilities must be installed on server. Unfortunately, all my scripts must be rewritten again. The work is in progress.

Are you ready for action? :)

The project is moving on! New set of candidates, from n=1,5M to 3,0M, will be loaded on Saturday, 16 May 2020, at 09:00 UTC to "LLR2 testing" on GFN Server.
(If it's not a best time for your timezone, don't worry - it'll be about 1000 other workunits in the queue at that time, most of them must be purged before new could be served, so really it'll be few hours delay).

If you're new on my server, you must register on site first, using invitation code PrimeGrid. Project url is http://boincvm.proxyma.ru:30080/test4vm . After registration, go to "Your account" - "Private GFN Server Preferences". Edit settings, check "Run test applications" option and select "LLR2 Testing" project.

Primes will be big enough for T5K. This round of testing ends very close to Mega range.

Multi-threading is supported and recommended, via classic "app_config.xml" method. Use same "-t #" option (e.g. -t 4) - need a space between option and value. Application name is "llr2".

LLR2 will be configured to use Pietrzak scheme with 32 or 64 checkpoints (depending on how large tested number is), compressed to 5 or 6 upload files. Maximum upload size will be 3 MB per task.

For those who didn't heard about LLR2, it's main advantage that it contains new algorithms which do not require doublechecking. Since each task is sent to one user only, you always will be first prime discoverer.
A very short "certification", sent as a separate task, is used instead. It's like a electronic signature which could be verified quickly. The certification task should take only 1-2 minutes on modern processors. Attempts of mass abort of certification tasks will be tracked and punished.

A multi-threading for LLR2 requires a space between option and value, like '-t 4'. I've fixed post above.

IP address is correct and site is working. Unfortunately, it seems to be some net routing problems between you and me. You could try 'traceroute boincvm.proxyma.ru' (Windows: 'tracert boincvm.proxyma.ru') to see where it dies. I've seen some weirdness on the net in last few days; for example, berkeley.edu site was inaccessible for me for few days, routing died somewhere in the Finland.

Looks like my ISP (AT&T) gets "lost" after it leave their main backbone (hop 5) to the rest of the internet from my home network:

As I said early, strange things are really happening recently, big parts of the internet are losing connection with each other. I don't know are these problem caused by human/configuration errors or it's a another round of BGP hijacking. But alas, nothing can be done here. A routing between AT&T and Europe is definitely beyond our control. Also sometimes ISP becomes a big brother, "protecting" you too much, completely blocking IP addresses which he didn't like by some obscure reason (like "who ever need to connect to IP address belonging to the huge home network provider in Russia?") The online service which you've used have another exit to world backbone and is not affected by this problem.

I've tried to trace some of AT&T routers from my side; it dies either somewhere at gtt.net either at telia.net routers. I've tested it from home, using another ISP and exit path, and also cannot reach at&t.

Thanks for your help Stream. I have opened a support ticket with my ISP (ATT) pointing them to the forum posts here. Doubtful that they will be of any help, but you never know.

This is an independent search, it will not change your PG credit or prime counts.
Eligible primes will be reported to T5K under your name with GFN server credited as organization (in exactly same way as on PG).

No primes yet.

(Percentage is based on raw 'n', not on amount of work, so progress will slow down with time because tasks are getting larger and slower as 'n' grows).

I was reading the routing issues happening earlier and I suspect it may happen again. We see peering issues and probable web communication blocking a lot in today's world. The issue is the bots are not smart and will stop one way traffic on a site it think might be threatening. As we know BOINC projects have very random code in the files, some of it sets off malware, defender and virus alarms. If those are hit enough through the detectors at the ISP, they will block a site. Hence your ability to still ping/trace the site because that is still allowed, but coming back is blocked. One way block as not to make you suspicious. Having worked in network security I had this happen on private VPN connected lines. I had to prove it was the ISP and it was not always easy to get the block removed, since I was not the owner of the connection that was being blocked.
It was good you communicated back and forth with the traces, because it showed the exact spot, which was the ISP that was blocking the incoming traffic. So the HELO made it over, but the response never made it back.

I'd say we go up to 3.32M first :) Then we can sieve deeper to 10M, which I'd suspect is already underway. :)

Expecting that all remaining candidates will be, at least, sent to users within next 36 hours. Since we have no primes yet, search will be extended as far as current sieving depth permit, but no more then 4M.

Regardless of this discovery, since new work was promised it will be loaded.

Yes, using extra command line in app_config.xml. It's a bit tricky.
<app_config> <app_version> <app_name>llr2</app_name> <cmdline>-t 4 -c -oCPUSupportsAVX512F=0</cmdline> <avg_ncpus>4</avg_ncpus> </app_version> </app_config>

"-t 4" (note a space between two) and <avg_ncpus> are for multi-threading (using 4 cores in this example)
"-c" tell the wrapper to pass next word as an extra argument to the LLR
And finally, "-oCPUSupportsAVX512F=0" is an new LLR option which will be added to LLR command line (it can be checked in task stderr output), to disable AVX512.

Looking at the tasks I've gotten in the last day or two, it's either 68633 or 76877, and most likely 68633.

I have lots of the tasks for the other 4 k's with n's near the leading edge. 76877 highest n is about 3.0M, but I only have recent double check tasks for 68633 around 2.6 or 2.7M. So 68633 seems like the best bet.

Usually, you don't need to. You are notified as soon as the prime is submitted to T5K.
This one takes some time because it's the first reportable prime found by LLR2. T5K needs to approve LLR2 first.

Primes are reported manually (I do this for GFN server; on PrimeGrid any admin can).

When reporting a prime, it's good habit to specify all software used in the search. LLR2 currently is not registered on T5K as separate program, we're waiting for this to happen (it must be done manually by T5K owner). So why reporting of this particular prime is delayed.

I think I basically took all the tasks from 3.2M to 3.3M yesterday. Wonder if this will be my lucky range...... Also, I think it is 68633 that has been eliminated. Got tasks for each of the other multipliers but not 68633. Great job to whoever found the prime!
