FYI, Greg reached out to me (at Carlos’s suggestion) re: becoming a 14e/15e mod. I’m willing to do it but will likely need some handholding early on.[/QUOTE] Excellent!

Yeah, all polynomials between posts #1566 and #1593 inclusive should now have been entered into the 14e and 15e management pages, and 5 14e numbers + 4 15e numbers are now in the SIEVING state :smile:
Hungry clients immediately restarted chewing WUs, and more than half of those in queue were already consumed, so it looks like I need to start at least another number to prevent starvation by tonight... Dmitry: the "type: gnfs" line is missing from the Aliquot polynomials you posted :wink: Historically, this caused an immediate rejection of the polynomial by the siever, and therefore WU failures; things are probably still that way, the Web interface has no check against that. So I've fixed the polynomials while queuing them. Sean: good to see that Greg contacted you at Carlos' suggestion. I'll provide the handholding early on :smile: You can double-check the current bunch of numbers in "QUEUED for SIEVING" and "SIEVING" states, as well as expand the ranges when needed. You'll notice that I usually trim the comment lines in the polynomials, to make them easier to review: for instance, 5419_67_minus1 and most OP tasks with simple (two-coefficient) polynomials don't need scrolling in the input dialog, they fit exactly the default number of lines displayed, so I use that as a quick double-check. Then, you can create entries in either queue, and I'll do my best reviewing them - I did my share of mistakes over time, we all did anyway... Suggested Q ranges, test sieving yields and target number of relations are definitely nice for queue managers, but I didn't have those for most of the hundreds of numbers I dealt with since 2009, so maybe they shouldn't be a requirement - or better, this is a good opportunity to further share the test sieving infrastructure and knowledge among "project scientists" :smile: I usually target 55-60M raw relations for a 29-bit LPs task, 110-120M for 30-bit, 210-220M for 31-bit. I seldom handled 32-bit and 33-bit tasks, but I know that the targets almost double for every additional bit of single large primes. |
Hey Sean, glad you were contacted by Greg.
Lionel, what about a Skype call with share screens with Sean so he can easily familiarise himself with the management system, might be a good idea.. |
Well, I don't use any communication system of that sort outside of work, and even at work, only very infrequently :smile:
I forgot to mention that the "Add Number" button is at the very bottom of the management pages. |
Please note, C200_224xx917_19 on the 14e queue is really a 31/32 hybrid which only needs about 330M relations.

Perhaps this is a good time to remind submitters to include a suggested Q-range to hit their target relations count.[/QUOTE] Any ideas on Q range for [url=https://www.mersenneforum.org/showpost.php?p=494880&postcount=1577]C200_224xx917_19[/url]? It’s tricky and I don’t have my handy homemade integration tool, er, handy. The poly file does have the line [code] lss: 0[/code] Which IIRC is the flag for -a sieving, so that seems good. ETA: Assume Q0 = 20M. That value is already in 14e and I’m reluctant to change it at this point. As RichD points out in the post previous to this, we need ~330M relations. I could just keep raising the upper value of Q behind the scenes until we have sufficient relations if necessary, but that seems the less than optimal method. Thanks to all helping here. So far queue wrangling doesn’t seem too bad, but Lionel did most of the work. |

I use a quick eyeballing tactic. The first range is about 6100 to 9900 so the midpoint (or average) is 8000. So I take 8K divided by the 5K block and multiple by the 40M range which yields 64M in this range. Next range is 5800 to 6000 or 5.9K average. 5.9/5 x 40M = 47.2M. Running total of 111.2M. Next is 5400 to 5800 or 5.6K average. 5.6/5 x 50M = 56M. Running total 167.2M Next is 4000 to 5400 or 4.7K average. 4.7/5 x 50M = 47M. Running total 214.2M Next is 4000 to 4000 or 4.0K average. 4.0/5 x 50M = 40M Running total 254.2M Next is 4000 to 4600 or 4.3K average. 4.3/5 x 50M = 43M Running total 297.2M The two 4000 yield seems to be a bit out of line so a good starting point might be Q=20-350 or 360. Then add more as needed. My two cents. |
RichD nicely wrote what I generally do. :tu:
Yields below 1 make me sad. |
As long as the number is in QUEUED for SIEVING state, the starting q value, and other parameters, can be changed.
The 14e clients are going to starve by the end of this European morning, so I'll start this number very soon anyway, unless Sean is in a comparable timezone and beats me to it. That's a persistent issue with the 14e grid: clients chew through WUs very quickly, which makes for a poor management effort / amount of food for clients ratio. |

Done. I think I got it but please check my work. While I was in there, I also corrected the poly for C241_148_110 - it was missing the "n:" in the first line. I checked my original posting and I own the error. :blush: At least it was corrected before sieving started, Also added some postprocessor names to 14e that appeared tonight. |
I have no immediate numbers to add. Maybe one or two in the next 5-7 days.
Are there other projects that would like to submit numbers, at least for the 14e queue? Aliquot? |
Sean: doh. Good thing you found the error I failed to detect as well :smile:
The poly looks alright, it has the appropriate number of lines for a two-coefficient polynomial without lss: line anyway. Neither ^, nor - are reserved characters for Windows or *nix, so the "5009^73-1" prefix for filenames will be alright. Historically, we've avoided such names - in fact, yesterday evening, I created and immediately deleted an entry for this exact reason, that's why there's a hole between #1448 and #1450 - but AFAICT, we don't [i]have[/i] to avoid such names. |

I should have remembered this fact about naming conventions but did not. Why don’t I change it to 5009_73m1? Or can the name be changed now? If not I’ll delete this entry and add it back with the better name choice. Even if it shouldn’t break NFS@Home, why risk it? You mention “lss:” - should this always be present in the poly or only lss:0 if sieving on the algebraic side? |
At best, the "5009^73-1" prefix could now be changed only by Greg, or whoever else has direct write access to the database. It's the only non-editable field in the Web form, and I've just checked that the comment for that database field in the SQL schema reads "number name (cannot be changed)".
It's simpler to create a new entry, copy the contents, and delete #335. The "lss:" line needn't be present if the sieving side is the one corresponding best to the "type:" line. Most polys I managed over time do not have "lss:" lines. Or put another way: if the original poly has one, I usually keep it, but I don't add it if it's not there. I've just noticed that polys for e.g. C215_46988659_29 and C210_35111_47 (14e) and C253_131_98b (15e) do [i]not[/i] have "type:" lines - so the fact is that the whole chain works without it, but I didn't remember about that... There doesn't seem to be any code to fix up the poly, so the sievers seem to be able to cope without these lines, I guess. I remember that missing "skew:" lines caused immediate failures for several past RSALS and/or NFS@Home. |
C179_374xx231_19 has a high dup rate (which doesn't surprise me). Can we get a few more relations added to this guy? My last 31-bit job had 178M+ unique relations and built a matrix at TD=120. This failed at TD=112 with 154M unique. I may peek ahead at a couple others. In the mean time I will take another number - posting in the appropriate thread.
[CODE]Found 154649059 unique, 65501730 duplicate, and 6681 bad relations. Largest dimension used: 568 of 1200 Average dimension used: 472.0 of 1200[/CODE] |
Alright, I raised the upper bound for C179_374xx231_19 to 300M.
The poly doesn't have a "type:" line, but since it has a "lss:" line, I'd expect it to have been sieved on the right side anyway. |

(not 2x lpba) and high alambda 3.7 sieving on [U]algebraic[/U] side (I thought SNFS were mostly sieved on the rational side???) :confused2:[/QUOTE] [B]VBCurtis[/B] did a great job explaining the mechanics of the polynomial, let me see if I can explain the logic. The OPN numbers are pretty much cookie cutters once you get a working polynomial. Each exponent would have a general form. For p^5-1 and p^7-1 you can divide out a p-1 to make a quartic or sextic. For p^11-1 and p^13-1 a degree halving technique is used to get a quintic or sextic. For p^17-1, p^19-1 and p^23-1 these are troublesome SNFS jobs because of the large coefficients. For sizes suitable for the 14e queue it is better to sieve on the algebraic side. Beginning with p^23-1 and up, these are more traditional SNFS jobs with smallish coefficients. But if the coefficients get too big (say, greater than 7-8 decimal digits) then the algebraic side should be considered. I think I had a large p^31-1 (or a p^29-1) on the -a side not too long ago. The number you question is a SNFS-235. I had a recent (C179_374xx231_19 - SNFS-239) job that barely fit as a 31-bit job. For some reason the yield was not good at all for the SNFS-235 number. When I bumped it to a 32-bit job, it seemed to be an overkill wth yield above 3:1. To squeeze more yield one can expand the lim’s but that usually only adds about 10% more with a 30% or so penalty in relations time. Another option is to use 3LP on one side. (You can’t use 3LP on both side because GGNFS will barf.) This is more beneficial with OPN numbers. Occasionally the time per rel will slightly decrease but generally one can get a 10-20% bump in yield with only a small penalty in time. So I decided on a hybrid. Most of my 32-bit post-processing jobs take 2-4 weeks while the 31-bit jobs are around 5-8 days. Split the difference, 2-2.5 weeks??

[QUOTE=RichD;495886]
I believe you suggested a yield of 2:1 with an end point of no greater than two times lim, which I thought I followed. My bad.[/QUOTE] Well, that job turned out to run Q-range of 390M for 460M relations, which is a yield of less than 1.2. This is just the sort of job I'd run 33LP without a second thought; typically 70% more yield happens, which in this case would be ~2.0. At least you have enough relations to get TD140 to work! I agree about trying pretty hard to not have to sieve above 2*lim, though I'm coming to question whether setting lim above 268M is a good idea for jobs that sieve to ~600M or so. Siever memory use and matrix difficulty seem to both jump quite a bit when changing a lim from 268M to ~400M. I'm by no means sure this is correct, but I've been doing the following on both 14e and 15e queues: If Q max projects to between 130M and 160M, I use 134/134M for lims. If Q max projects to between 160M and 225M, I use 134/200 for lims (smaller lim on sieving side) 225-300 gets 200/268M (I test 134/268 also) 300-500 gets 268/268M (I may test 268/400) 500+ gets a *lot* of test-sieving and no firm plan, but 268/268 vs 268/400 vs 268/536 vs 400/400 are likely tests. |
I'm downloading copies of the C228_23827_53, C215_46988659_29 and C179_374xx231_19 raw datasets, all 31-bit LPs 14e tasks. The process should finish by 15 minutes from now; then, the raw datasets can be erased from the server to reduce disk pressure.

There were some concerns earlier about the memory use of the 14e client which was surpassing the guidelines. I guess you can’t make all the people happy all the time. :smile:
One thing I did notice on the more traditional SNFS OPN jobs, where the exponent is above say 40-50 which means the size of the coefficient would only be 4 or 5 digits, one can cut the rlim is half and have no affect on the yield. This might save client memory footprint. And might also save 1-3% in timings. For example: [CODE]rlim: 67000000 alim: 134000000 lpbr: 31 lpba: 31 mfbr: 62 mfba: 62 rlambda: 2.6 alambda: 2.6[/CODE] I suppose I should also look at pushing some of these to 30 or 31-bit jobs on 15e where larger memory usage is expected. |

Although it would be slightly less efficient than using 15e, a 31-bit LPs task of SNFS difficulty 247 would help filling the 14e queue.
But both queues are still broken anyway... |
This is definitely a 32-bit job if parameterized for the 14e queue. I was surprised how easy it worked as a 31-bit for 15e.
Edit: The best I could squeeze in 14e was 134/200 31/91a/3.6. The yield at 60M was 1.36. The kick in the pants is the seven digit coefficient. |

For the OPN numbers, can we please keep the filenames on the server and the displaynames on the statuspage as recognisable as possible? (see what happened in the 14e)
My personal preference is the C200_1234567_89 names and not the Phi123/Phi45/6789 etc names. Just my 2 cents |
In fact, the 14e management Web interface automatically copies the field containing the "name", used for filenames, to the field containing the "display name". In RSALS times, as well as for more than the first half of NFS@Home's 14e activity so far, the name and the display name matched.
We could ask Greg to modify several lines in crunching.php and crunching_e.php so that the "Now sieving", "Queued for post processing" and "Post processing" tables contain the (currently missing) name and the (currently displayed) display name.

Try 32/64, and 32/92-64 (92 on the a side). I've found fastest performance (though not best yield) with mfba =3*lpba -4. 93 could be tested also. I use a rule of thumb that going up an LP requires 70% more relations, so sec/rel should be approx. 1/1.7 the time of 31LP. If I try a hybrid 31/32, I aim for 30% more relations than I would have for the smaller LP size alone. If you'd like me to do some test-sieving, I'll have time (and interest) Sunday. I'm interested to test-sieve one of these large-coeff SNFS candidates, so if you wish I'll tackle it then and post a writeup about test results. |

Now I see the job is queued using the set that didn’t work very well at all. I am questioning whether we can get enough good relations to build a matrix with TD=120 or better using the bad set I had abandoned...

It does seem to be working out satisfactorily. Though not anywhere near optimal - but working. I was thinking 32-bit job when I looked at the accumulated relations with Q already at 400M. It should be fine. My blunder was bigger by grabbing the wrong dataset and claiming the job was completed so all the data can be deleted. Which strike me a bit odd since there are several OPN datasets still in the directory from last April. Why would such a recent job be deleted so quickly?? Thanks for re-queueing a second copy. |

Sextics usually sieve better on the algebraic side, ie pass -a to the siever. I've run my script to check .polys against it and there's not much in it but the algebraic side should be better. Or you might want to sieve on both sides if the yield drops too much at higher special-Qs.
