I reserved 7 near-repdigit numbers for NFS@Home nearly three months ago. 3 of them need more ECM work (all the way to t55, unless the rule of thumb changed recently) before they can be queued, and [b]I need help for that[/b] :smile:
I'm saving the optimized polynomials here. The near-repdigit site suggests 30-bit LPs even for the SNFS difficulty 247 number, but in such conditions, the yield is usually horrible. Also, I raised alim and rlim a bit.

Are you sure about the lpbr and lpba size?
|
[QUOTE=pinhodecarlos;501617]Are you sure about the lpbr and lpba size?[/QUOTE]
I'm sure those were the values I was using when I collected the numbers I show during test sieving. Why do you ask? |
I’m just confused about your chosen sieve range and lpb sizes.
PS(nevermind , I didn’t look at the trial sieve values) |
Time for my periodic reminder that choosing LP bounds that cause average yield below 1.0 is distinctly suboptimal. It is a fallacy that matrices from such jobs are easier and smaller than the same job with 1 higher LP bound; matrix size scales pretty steadily with input difficulty, and not very much at all with LP choice provided LP is 32 or lower.
Q-ranges of 100M or greater should use 31LP, as using 30LP would mean a yield around 1.0-1.2. Q-ranges of 180M or greater should use 32LP, as using 31LP would mean a yield around 1.2-1.4. Q-ranges of 320M or greater should likely use 33LP, or 15e with a much smaller Q-range. An example of the last situation: I test-sieved 13*2^870-1 and found I'd need Q of 20-330M on 14e, but just 20-133M on 15e. I cut alim and rlim in half for the 15e tests. The only reason I know of to stick to smaller LP choices is to save disk space on the server; I've been submitting jobs that are faster at 33LP as 32 or 32-33 hybrid to save 200M relations' worth of disk space. |
Thank you Curtis for your last message.
Hope next year I can afford a new machine so I can do the 31-32 bit jobs. |

Change that rlambda to 3.6 rather than 3.0!
Or maybe I don't understand lambda at all.... I've usually used 2.x for 2LP, 3.x for 3LP, where x is 6 or 7. Sometimes I test-sieve x=6 vs x=7, results haven't told me much. I think if you test-sieved with 3.0, you were actually test-sieving 2 large primes rather than 3? |

So while I certainly don't know better than you here, I'm not terribly inclined to make this change without some further explanation. Edit: And by the way, saying "I don't really understand why, but this will speed up sieving by 10%" would be a perfectly fine explanation for these purposes.

Well then, here would be an opportunity to do a controlled scientific experiment. Use the suggested value and do trial sieving on the same regions. Voila! You now have data. |
I don’t thing we should care about the sieve speed since it is done by others. What we should concentrate is achieving smaller matrix. The former we can’t quantify when we are using the NFS grid (generally speaking).

My comments about 2.0 and 3.0 were meant as evidence that my first explanation of lambda couldn't be correct, because both standard practice and test-sieving shows that 2.5 or 2.6 is always better than 2.0 or 2.1; the idea I tried and failed to convey is that using 3LP means adding 1 to that side's lambda. If you accept that 2.6 works for normal 2LP jobs, please accept that 3.6 is what works for 3LP jobs. Or, as axn says, test-sieve a bunch of lambdas and let us know what you think. But be warned that test-sieves will show different effects at different Q values; it's messy, or else we'd have a clear best choice already. |

Okay, well here's some data for the last number I posted (HCN 7+6,320): [code] 2.6 3.0 3.6 --- --- --- Q Yield sec/rel Yield sec/rel Yield sec/rel --- ----- ------- ----- ------- ----- ------- 20M 5235 0.20297 5264 0.20422 11022 0.13363 50M 7521 0.15008 7540 0.15242 12750 0.14660 80M 8104 0.14465 8117 0.14794 12003 0.15987 110M 9760 0.14617 9765 0.15100 13317 0.17087 140M 8957 0.15357 8960 0.15806 11798 0.18048 170M 8842 0.15327 8848 0.15776 11572 0.18024 200M 8993 0.15947 8998 0.16470 11802 0.18607 230M 8577 0.16492 8585 0.16982 11204 0.19071 [/code] As you can see, a lambda of 3.0 isn't appreciably different from 2.6. But moving it to 3.6 changes things substantially. And as you said, the effects are quite different for different Q values. Across the whole range, yields are quite a bit higher, but completing a given range is quite a bit slower. And for purposes of assessing total speed of sieving, these two effects run counter to each other. At lower Q values, the speed is greater (very much so for Q around 20M), while at higher Q values it's worse than using a lambda of 2.6 or 3.0. For determining which is the better choice for this particular number, I note that the higher yield with lambda=3.6 means having to sieve a smaller range (probably just up to about 120M), so we'd spend more of the time in the Q ranges where that higher lambda gives us better speed. Still, total sieving time probably ends up being fairly close, regardless of which value we choose. However, when thinking about this in terms of NFS@Home, the practical effect of using the higher lambda is that the smaller range means fewer work units get generated, and each one takes longer to complete. That cuts down on the parallelism that we get from having thousands of cores doing the sieving. So the higher lambda may slow down the completion of sieving this number. More generally, if other numbers have the same characteristics, then we get individual numbers potentially taking longer, but only because they are handed out to fewer cores. I.e. it increases the latency, but it should not affect the throughput of the grid as a whole. On the other hand, I don't know what effect the higher lambda has on eventual matrix size. My intuition is that the smaller range of sp-Q means a smaller matrix, but I don't have enough experience to trust my intuition on this point, so someone please weigh in. But if that's true, then I would argue it's a tradeoff worth making. I.e. increasing the latency of each number, but also decreasing post-processing time seems like a fine tradeoff, and all the more so if it doesn't hurt throughput. Any more knowledgeable thoughts and opinions are welcome. (Less knowledgeable ones are also welcome, but being more knowledgeable than myself is a low bar.) |
The similarity in yields between 2.6 and 3.0 tells you that 3.0 isn't actually using 3 large primes. The yield from 3.6 looks like the usual result of 3LP: much higher yield, and sec/rel that increases quite a lot more with Q than it does with 2LP. I'm quite interested to compare 3.6 to 3.7 to either.3.5 or 3.8; perhaps I'll do so next time I test-sieve for 15e queue.
I did a bit of comparing jobs in my 13*2^n-1 factoring personal project, running some with 3LP and other similar-difficulty jobs with 2LP. It seemed that 3LP produces matrices slightly larger than 2LP, such that I wanted to see a clear win in sec/rel for 3LP in order to use it. I didn't see that clear win until roughly SNFS-250+; on GNFS jobs I haven't done enough work to have a good estimate (I would guess 183 or 185 for 15e queue, but it's lower for CADO). |

I appreciate the vote of confidence, though I'm not entirely so confident myself. In particular, there may be limits to the predictive value of trial sieving on small ranges. One point on which I know I'm ill-informed is just what kind of effect using more large primes actually has. I vaguely recall getting the impression that a lot of the advantage of large primes doesn't show up until late in the sieving, when there are already a lot of relations gathered. If that's true, then an important effect of large primes is not captured by doing trial sieving, and I have heard no good guidelines on how to estimate that effect. So while I may choose the set of parameters that suggests the best times during trial sieving, it's still possible that your more "normal" parameters would still lead to a better outcome overall. Any additional education you (or anyone else here) can give me on this point would be welcome. |

Ah, well now this is an interesting point. The last time I messed around with quartics, a couple of years ago, I recall noting that an SNFS difficulty of 225 was the point at which it seemed better to use the 15e siever. However, I know I wasn't exhaustive in my investigation, so it's possible that the crossover point could really be a bit lower. But in any case, you raise a good issue. I should really add 15e to the mix and see what happens. Of course, trial sieving aside, the lag time before we actually know how well the parameters have been chosen is much greater for 15e because that queue is well-filled, unlike 14e, which is always begging for new candidates. |

yoyo@home clients have nearly finished raising ECM work for 99299_121, 50009_245 and 33833_123 to t55, so I'll be able to add them to the 14e queue soon...ish.

There is a 'type: gnfs' line in the poly, isn't this not enough to sieve on algebraic side? |
[QUOTE=unconnected;503213]There is a 'type: gnfs' line in the poly, isn't this not enough to sieve on algebraic side?[/QUOTE]
I’m not certain. The command line “lss: 0” definitely forces sieving on the algebraic side. |
Ok, no problem, next time I'll use 'lss: 0' for gnfs tasks. Thanks for explanation.

The 14e queue seems stuck on 5_2_760m1. I’ve reported the behavior to Greg, waiting to hear back. I’m hoping 44111_47m1 will process normally, and maybe even fix the glitch with 5_2_760m1. Otherwise it is in Greg’s hands. Or in a few days I kill the stuck job(s), and then resubmit after an appropriate amount of time has passed.
Any insights would be appreciated. |
