Welcome to the Reign Record Challenge

We here at PrimeGrid love our records! In recognition of Queen Elizabeth II's (most likely) record of being the longest reigning monarch of Great Britain as of September 10th, PrimeGrid is hosting a a 5 day challenge on the Cullen LLR subproject.

To participate in the Challenge, please select only the Cullen Prime Search (LLR) project in your PrimeGrid preferences section. The challenge will begin September 10th 2015, 18:00 UTC and end September 15th 2015, 18:00 UTC. Application builds are available for Linux , Windows and MacIntel 32 bit and 64 bit. CPU's with AVX capabilities will be significantly faster than the ones without, as this instruction set allows for more computing power.

ATTENTION: The primality program LLR is CPU intensive; so, it is vital to have a stable system with good cooling. It does not tolerate "even the slightest of errors." Please see this post for more details on how you can "stress test" your computer. WU's will take about just under a day on fast/newer computers and two to three days on slower/older computers. If your computer is highly overclocked, please consider "stress testing" it. Sieving is an excellent alternative for computers that are not able to LLR. :)

Restricted airflow is one of the primary reasons for overheating. Take the time to monitor the fans and review the dust buildup. Please, please, please make sure your machines are up to the task.


Time zone converter


    The World Clock - Time Zone Converter

    NOTE: The countdown clock on the front page uses the host computer time. Therefore, if your computer time is off, so will the countdown clock. For precise timing, use the UTC Time in the data section to the left of the countdown clock.

Scoring Information


    Scores will be kept for individuals and teams. Only work units issued AFTER September 10th 2015, 18:00 UTC and received BEFORE September 15th 2015, 18:00 UTC will be considered for credit. We will use a similar, but not the same, scoring method as for BOINC credits .

    Therefore, each completed WU will earn a unique score based on its n value. The higher the n, the higher the score. This is different than BOINC cobblestones! A quorum of 2 is NOT needed to award Challenge score - i.e. no double checker. Therefore, each returned result will earn a Challenge score. Please note that if the result is eventually declared invalid, the score will be removed.

    For details on how the score is calculated, please see this thread.

At the Conclusion of the Challenge
We would prefer users "moving on" to finish those tasks they have downloaded, if not then please ABORT the WU's instead of DETACHING, RESETTING, or PAUSING.

ABORTING WU's allows them to be recycled immediately; thus a much faster "clean up" to the end of an LLR Challenge. DETACHING, RESETTING, and PAUSING WU's causes them to remain in limbo until they EXPIRE. Therefore, we must wait until WU's expire to send them out to be completed.

Please consider either completing what's in the queue or ABORTING them. Thank you. :)


Best of Luck!!!

Cullen Primes
Cullen numbers are a special kind Proth number. They were first studied by James Cullen in 1905 and are of the form n * 2^n + 1.

As of August 2009, the largest known Cullen prime is 6679881 * 2^6679881 + 1. It is a megaprime with 2,010,852 digits and was discovered by a PrimeGrid participant from Japan.

A Cullen number Cn is divisible by p = 2n − 1 if p is a prime number of the form 8k - 3; furthermore, it follows from Fermat's little theorem that if p is an odd prime, then p divides Cm(k) for each m(k) = (2k − k) (p − 1) − k (for k > 0). It has also been shown that the prime number p divides C(p + 1) / 2 when the Jacobi symbol (2 | p) is −1, and that p divides C(3p − 1) / 2 when the Jacobi symbol (2 | p) is +1.

It is unknown whether there exists a prime number p such that Cp is also prime.

You might be interested to know, that on Weds (when apparently she becomes the longest-reigning monarch at about 4.30pm, I read!) the Queen will be officially opening the new Borders Railway, which runs close to where I live. You can read about it here.

The railways actually opened to the public today (Sunday), and I was one of the lucky 500 or so people to take a 'Golden Ticket' trip on the Saturday. Here are a few photos (more on my Twitter Feed)

I agree. We should limit challenge names to scientific types including Scientist, scientific events and discoveries, including astral events like eclipses, solstices & equinoxes. Even a certain harvest type would suffice. Political people and events should never be a reason for a challenge even if a now weak political figure is involved.

I'd like to point out the previous challenge names, none of which are scientific in nature, and none of which has had any controversy:

Shakespeare's Birthday Challenge
Sovereign Challenge
World Animal Day Challenge
Saint Nicholas' Challenge

And that's just from last year.

The place to talk about challenges (and challenge names) is during the planning we do each Fall for the following year's schedule. If you have a problem with the name, that's the time and the place for it.

If you object to this kind of name for a challenge, please raise your objections when we start talking about the 2016 challenges. That's your opportunity to be heard.

Let's keep THIS thread all about the challenge itself, and keep the politics out.

Michael laying the hammer down....

Anyway, this'll be a dull challenge for me. My CPU took a bit over 4 days to crunch each WU, and being a triple-core, I'll only be able to get 3. I'll just show up on the ranks at the very end of the challenge. But hey, I'll see you guys there.

keep the politics out.


I agree. PrimeGrid should keep politics out, so rename the challenge to something not so blatantly disrespectful to those of us who take serious issue with monarchs/royalty/undemocratic figures.

This is supposed to be a math project, not a practice in royalty-worship. I absolutely HATE royalty in every single country where it exists. All kings and queens owe their subjects deep apologies and should step down from their undeserved positions of power & influence.

I will certainly not be participating in such a challenge, and if the name is not changed, I will stop participating in PrimeGrid altogether.

As for previous challenges with non-scientific names, I don't know what exactly "Sovereign" is supposed to refer to, but Saint Nicholas is not a good idea either. I don't see problems with Shakespeare or World Animal Day.

"Politics and religion"...

To host a math challenge in order to celebrate Queen Elizebath II's reign of blatant entitlement is extraordinarily offensive to me and others. I'm an American libertarian. I utterly HATE royalty.

Obviously, you can do what you want with your own property/website, but you should certainly be aware of how offensive royalty-worship can be to Americans or people of various political orientations...

My intention is not to upset anyone here but to point out that I am upset with the idea of such a "celebration". You would run into the same problem with an "Adam Smith" or "Karl Marx" celebration. Please stick to math and science.

I will voice my opinion when and where I want to. If you wish to operate in such an authoritarian manner, that will just further motivate me to leave. I don't appreciate such attitudes when it comes to freedom of expression. You have to respect the people who contribute their CPU cycles to this project. I can certainly go back to GIMPS or find another project to contribute to.

keep the politics out.

THIS IS the reason for the comments, to remove any politics from this or any future challenges. The comments by Christopher Siegert is surely felt by many VOLUNTEER crunchers that are being treated here in a similar authoritative manner, commanding us to not speak about certain aspects of this challenge. A lot of people don't even read the preseason naming thread and some are afraid to create waves on the issues. So discussing about the name of THIS challenge in THIS thread is more than appropriate I believe, especially before the challenge actually starts.

We're not trying to censor anyone, we were just trying to keep this thread on-topic. Since that's probably not going to happen, I'll post here too. Let's try to keep this civil, no need to start flaming others. A political discussion is unlikely to change anyone's point of view, so I'd just as soon avoid it.

In the division of labor here at PrimeGrid, Charley is the one in charge of the challenges. He does a very good job with them and I'm reluctant to immediately step on his toes and change the name of this challenge. As I post this, it's around 3am where he lives and so I don't expect him to see it immediately. He needs to be involved in any discussion over the challenge name and whether it needs changing.

Just for myself, I'm wondering if anyone has an alternate name? I note there's a new moon right in the middle of this challenge, but those happen every 28 days or so. A quick look didn't show any birthdays of mathematicians that I recognized as involved in primes. Does anyone have any serious suggestions?

Came up with a somewhat big deal:
2008 – The Large Hadron Collider at CERN, described as the biggest scientific experiment in history, is powered up in Geneva, Switzerland.

Via Wikipedia:
Operational history

The LHC first went live on 10 September 2008, but initial testing was delayed for 14 months from 19 September 2008 to 20 November 2009, following a magnet quench incident that caused extensive damage to over 50 superconducting magnets, their mountings, and the vacuum pipe.[46][47][48][49][50][51]

During its first run (2010 - 2013) the LHC collided two opposing particle beams of either protons at up to 4 teraelectronvolts (4 TeV or 0.64 microjoules), or lead nuclei (574 TeV per nucleus, or 2.76 TeV per nucleon).[30][52] Its first run discoveries included a particle thought to be the long sought Higgs boson, several composite particles (hadrons) like the χb (3P) bottomonium state, the first creation of a quark–gluon plasma, and the first observations of the very rare decay of the Bs meson into two muons (Bs0 → μ+μ−), which challenged the validity of existing models of supersymmetry.[53]

Could carry the name: The Large Hadron Collider Powers Up Challenge

Just to be clear, when I posted above I was not in any way particularly condoning the monarchy (in fact I tend towards apathetic republicanism). I was much more excited about the trains, as you can see from the pics. The only link between the two is the title of the challenge...

For my 2c, I think the challenge name is not so much worth worrying about. It's clear that the project is no more supporting the concept of Monarchy than it does Chinese Astrology (Year of the Sheep etc.), Catholic religious festivals (St. Valentine's Challenge) or Mozambique nationalism (Sovereign challenge).

As already said, every year when we make the challenge schedule there is plenty time to comment on proposed names and we make every effort to keep accommodate all opinions. Making such a change at the last minute as a result of a vocal minority does not help, in my opinion.

(Hopefully not pouring oil on troubled waters, but still...)

Something just occurred to me, as I downloaded the new LLR app and wrapper in preparation for this challenge. Would it now be possible for WUs that don't entirely complete by the end of the challenge to get "partial credit" for their trickles? Perhaps losing that credit if they don't finish the WUs?

I imagine this would be a lot to do in less than 24 hours, but maybe for the next challenge? Or next year?

Theoretically possible (although obviously not for tomorrow), but the trickles weren't designed with that in mind and one problem that I foresee is that they're not designed to report in before the end of the challenge. There's going to be a 0-24 hour variance in how much partial credit people would get.

It's something we can think about down the road a bit.

5 days - 24 hours is better than nothing. Which is what it looks like my Core 2 will get on this challenge - each Cullen looks like it will take 6 days.

Every once in a while, a participant begins a challenge a little too early or a little bit late due to their computer's system clock being different than the actual time.

Is it possible to display a countdown clock on the front page as the time given by one of those sites like www.time.gov that show a government's official time, or a similar clock that shows actual UTC time? Just something that doesn't show a simple reflection of our own computer's internal CMOS clock time.

The server clock time is shown on the front page, but you need to hit refresh.

5 days - 24 hours is better than nothing. Which is what it looks like my Core 2 will get on this challenge - each Cullen looks like it will take 6 days.


Is it a quad? Try running only 2 tasks instead of 4, that might be enough to speed it within the deadline.

One of my computers is an AMD, so I am curious if it will be able to do only 6 or 12 wu's on its 6 cpu's. Looking forward to the challenge.

Yes, it's a quad. I'd been running 3 tasks, but that wasn't enough. I dropped to two, and that looks like it may just barely meet the deadline.

For my two duo cores I show 270 hrs (13.5 days) for the tasks to complete. I have no problem with this scenario if it holds since they have been running for only 15 minutes and the final estimate may change.

Since I will be getting credit anyway but not for the challenge, I can live with the 13.5-day runtime. As for the challenge itself, can the administrators live with the 8.5-day overshoot and delay?

My I7 quad core is showing 96 hrs for the time to completion and all eight cores running (for now) and well within the window for the challenge.

As an aside, what is the typical credit for these work units?

Sounds like the duo will aid clean-up, so all good,

8 cores?! You need to turn HT off. Try 3 cores then you'll get up to 9 fitting into the challenge period.

Credit is just over 10k.

I did one recently as a test and it got just over 10000 credits.

Oh, running 8 tasks on a quad core is almost certainly a bad thing. At best, you will get 8 in twice as long as running 4 at a time, but probably worse than that.

I would suggest going into the Boinc client, and in the menu select Options > computing preferences then set "use at most of CPUs" to 50%, so you only run 4 at a time. The other 4 will continue when the first 4 are done. Or like Dave says, 3 might be more efficient for the challenge, but it will depend on the exact PC configuration.

Thanks Dave and mackarel.

As for the credit, a silver badge (100k) should be doable as an added bonus. :-)

Looks like all three computers are running hotter and slower doing the CUL, as opposed to doing he PPSE wu's. The AMD may make it in time in 5 days, but it could be a squeaker. The other two seems to predict about 40+ hours per.

PPSE might be small enough to fit in modern CPU caches, but Cullens are much bigger and will hit ram bandwidth hard. You might even get better throughput running less tasks than cores.

For my two duo cores I show 270 hrs (13.5 days) for the tasks to complete. I have no problem with this scenario if it holds since they have been running for only 15 minutes and the final estimate may change.

The estimate could be wrong anyway. Check these workunits tomorrow at same time (after 24hours). If they did more then 20%, you'll be in time. Otherwise try to pause one of tasks (I assume your CPU has two cores). Cullen tasks requires high memory bandwidth, but core duo memory interface was slow, comparing to modern processors. So a single task on core duo could be run, depending on configuration, about 30% faster comparing to when you run them in pair - and you'll have a chance to complete at least one task in time on this PC.

We use a newer method for the time estimates, and once the task has been running for a few minutes the estimate should be fairly accurate.

That's fine. The deadline is 15 days. It's okay if you take the full 15 days (or even longer) to return the task. In fact, with the new deadline extension system, the server will give you up to 60 days as long as the computer keeps working on the task.

With 5 hrs of run time now behind me, I am now looking at about 225 hrs per task or under ten days. In other words, all is well.

For my two duo cores I show 270 hrs (13.5 days) for the tasks to complete. I have no problem with this scenario if it holds since they have been running for only 15 minutes and the final estimate may change.

The estimate could be wrong anyway. Check these workunits tomorrow at same time (after 24hours). If they did more then 20%, you'll be in time. Otherwise try to pause one of tasks (I assume your CPU has two cores). Cullen tasks requires high memory bandwidth, but core duo memory interface was slow, comparing to modern processors. So a single task on core duo could be run, depending on configuration, about 30% faster comparing to when you run them in pair - and you'll have a chance to complete at least one task in time on this PC.


Thanks, stream! No question I will look into it.

We use a newer method for the time estimates, and once the task has been running for a few minutes the estimate should be fairly accurate.


Not on my machine! Currently showing 77 hours left with 5.3% done after 5:45. By my calculations that should show 103 hours left.

Maybe I need a new BOINC version? Currently on 7.2.42.

Maybe.... Checking... Having trouble finding the information, but if your BOINC client is more than a year old it probably doesn't have that feature.

Yep, this race is for brand-new computers only, due to its short duration in combination with very long running tasks.

If I'm lucky I'll manage to get 8 WUs done inside the race. Another 16 or 24 will finish shortly after the race ended. I'm completing these only to help with the cleanup, but further races of this style going without me.

I strongly disagree with the characterization that this is a challenge for "brand-new computers only." Is it short? Yes. A lot of computers will only be able to do one set of tasks. Most computers will only be able to do 2 or 3 sets of tasks, and maybe some really, really fast computers can do four. Maybe.

But most computers are fast enough to participate.

This challenge is 120 hours long. In the database, there are currently 2288 validated Cullen results. 1918 of those completed in less than 120 hours.

(Also note that the 370 tasks that took longer than 120 hours weren't necessarily too slow for this challenge. I was being conservative and looking at elapsed time rather than cpu time. The computers may have been running other programs that would slow down the BOINC tasks. Also, many people run with hyperthreading enabled, which doubles the run times of these tasks. Therefore, at worst, 370 out of 2288 tasks were run on computers too slow for the challenges, but the actual number is almost certainly lower.)

CPUs that have completed Cullen tasks quickly enough for this challenge include:

AMD Athlon(tm) II X2 255 (2010) (no AVX)
Intel(R) Celeron(R) CPU 1005M @ 1.90GHz (2013) (1.9 GHZ laptop CPU without AVX)
Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz (2007) (no AVX)
Intel(R) Pentium(R) CPU 2020M @ 2.40GHz (2012) (laptop, no AVX)
Pentium(R) Dual-Core CPU E5300 @ 2.60GHz (2008) (no AVX)

And 233 other CPU types, many of which are at least as old or as slow.

Brand new Atom processors won't be able to finish a task quickly enough for this challenge.

Some CPUs nearly ten years old are fast enough.

It's definitely not a challenge for brand-new computers only.

Note there are ways to make older systems do units faster and maybe get some units in time (had you started them early enough).

For example, on my stock Q6600 at 2.4 GHz, I'm only running 2 challenge tasks. Last time I looked, it was predicted to take near enough 119 hours overall, with the challenge lasting 120 hours. It is going to be close! Although it is a quad core, by only running two tasks I've effectively doubled the memory bandwidth available per unit. It will help, but how much, I didn't have time to test before just doing it. If it looks like 2 units wont make it, I'll try reducing it to 1. If that doesn't help enough I could try a blind overclock. No time for stability testing, it will be all or nothing.

While boinc reports the CPU types, it doesn't give other details of the system performance, except possibly indirectly through the built in benchmark results. For example, we don't know if the CPUs have been overclocked or how much, or similarly if the ram has been too. It would be interesting to see average run times for those CPUs listed above, particularly the Q6600 to compare against mine.

Good news and bad news. The good news is I can get that information. The bad news is there's only one task that ran on a Q6600 in less than 120 hours.

That one task:

+----------+---------------+---------------+---------------+-------------------+-------------------+-------------------+ | count(*) | min(cpu_time) | avg(cpu_time) | max(cpu_time) | min(elapsed_time) | avg(elapsed_time) | max(elapsed_time) | +----------+---------------+---------------+---------------+-------------------+-------------------+-------------------+ | 1 | 408603.092 | 408603.092 | 408603.092 | 419652.67085 | 419652.67085 | 419652.67085 | +----------+---------------+---------------+---------------+-------------------+-------------------+-------------------+


There's 8 tasks in total:

+----------+---------------+--------------------+---------------+-------------------+-------------------+-------------------+ | count(*) | min(cpu_time) | avg(cpu_time) | max(cpu_time) | min(elapsed_time) | avg(elapsed_time) | max(elapsed_time) | +----------+---------------+--------------------+---------------+-------------------+-------------------+-------------------+ | 8 | 408603.092 | 523606.03967500007 | 575002.6308 | 419652.67085 | 537889.367791 | 615995.818496 | +----------+---------------+--------------------+---------------+-------------------+-------------------+-------------------+


Individual times:

+-------------+---------------+ | cpu_time | elapsed_time | +-------------+---------------+ | 511983.4531 | 512319.440462 | | 567356.6361 | 589209.429659 | | 575002.6308 | 615995.818496 | | 408603.092 | 419652.67085 | | 526823.5359 | 539611.734909 | | 529509.0619 | 542041.088308 | | 529409.8764 | 542946.508034 | | 540160.0312 | 541338.25161 | +-------------+---------------+


120 hours is 432000 seconds. My Q6600 died a while ago, or I'd do some tests on it. Just from the data, I can't tell whether the 1 fast task or the 7 slower tasks represents the nominal run time.

One thing which we may want to remember for next year is that this schedule was made up a year ago. Between then and now, these tasks undoubtedly have gotten longer. Although I'm not sure when this was measured, the last time I timed a Cullen task on this machine it took about 23 hours. These tasks are running running 40 hours. Some of that is due to me lowering the memory speed. But some is due to the tasks getting longer. When deciding how long to make the challenges, we should keep in mind that some of the tasks may grow in length by the time the challenge is run.

Without knowing more about the hardware configuration we'd only be guessing.

I just checked in on my Q6600 box. The 2 units are currently looking like 117 hours overall so I have a little breathing room.

On the faster end I see we have a unit on the scores now. I'll be joining in shortly with hopefully 2 units in the next refresh.

If some factors like HT enabled/disabled or using only one core, keeping the other cores idle are counting that much as we see here in this race, it's definitely the wrong style of race FOR ME.

MY opinion is that even slower computers like a stock un-oced Q6600 without maximizing-RAM-performance-by-disabling-cores-tricks should be able to deliver at least one "set" of WUs (four on a Q6600) within the race. The race duration needs to be long enough to ensure that.

But that is MY opinion, I didn't want to start a discussion/war on race duration times. And its MY choice to participate in such races - or not. Nobody needs to follow my opinion if I found these short races with long tasks unsuitable to me in the future.

If it is your wish I could startup a standard Q9550 machine to show the WU run time on these CPU. I assume it will *never* finish inside this race.

Fortunately it is not my job to organize races. :D

Hi Dj Ninja,

When determining the length of a challenge I take a look at the recent average runtime which you can find when editing your PrimeGrid preferences. For pure CPU challenges I always make sure the challenge is at least a day longer than the average time. Then some rounding happens to make the challenge a full amount of days, rather than silly numbers like 4 days 13 hours, 47 minutes and 58 seconds.

When I'm drafting up next years schedule (somewhen in October), I'll see if Michael can Goetz me some numbers on cpu types/speeds. Once I have those we'll see where it takes us :)

For ALL LLR or Genefer tasks -- that's the vast majority of what we run here -- hyperthreading doubles the time of each task. You run twice as many tasks at once, but they're running half as fast.

That's not going to change, and we *do* expect people to know about that. For sieves, hyperthreading is good. For everything else, it's bad. But no matter what, by definition hyperthreading will always slow down all tasks significantly. The only question is whether it's slowing them down by more (bad) or less (good) than 50%.

MY opinion is that even slower computers like a stock un-oced Q6600 without maximizing-RAM-performance-by-disabling-cores-tricks should be able to deliver at least one "set" of WUs (four on a Q6600) within the race.


I agree! I think what happened here is that in the 10 months or so since the challenge schedule was announced the tasks got longer. We should try and take that into account in the future. As you say, a Q6600 should be able to run these in time. It's not much slower than the pre-AVX Core-i CPUs, and I do expect all of those CPUs to be able to do the challenge. If they can't, we dropped the ball. We're not perfect.

If it is your wish I could startup a standard Q9550 machine to show the WU run time on these CPU. I assume it will *never* finish inside this race.


As a previous owner of a Q6600, I can tell you that the Q9550 is a lot faster than the Q6600. (Internally, they're very different chips.) The Q9550 times for the Cullen tasks are a lot faster and they should be able to finish at least one set of tasks.

Going forward, we (and by "we" I mean the entire community, not just the admins) should review the length of the long-task challenges a couple of weeks before the challenge. Conditions can change over the course of a year, and what was fine in November might be too short the following October. Lesson learned.

A good standard, I think, is that modern, 64-bit, NON-AVX CPUs should be able to do one set of tasks. "One set" should be defined as one task per physical core, i.e., hyperthreading off.

32 bit CPUs? No. Ultra-Low powered CPUs such as an Atom? No. Modern laptop CPUs? Yes. 10 year old laptop CPUs? Probably not.

There was a suggestion to use trickles for "partial credit" for challenges. As I said elsewhere, that's a theoretical possibility. If we do that, then we don't have to worry as much about being able to complete the tasks by the end of the challenge. But that's something to think about for 2016.

In my setup, minimal Core Duo E-series processor which, I hope, will compete two tasks, is "Pentium(R) Dual-Core CPU E5700 @ 3.00GHz". It's estimated time is very close to 120h. May be it fits, may be I have to disable one task closer to the end. Everything below must have one task disabled.

Double-channel memory setup is mandatory. These my old boxes which also have only one DIMM installed will be not capable to complete even one workunit. I let them crunch, although they'll count only for next badge...

More modern non-AVX processors like G850, G860, G3220 have no problems (expected about 76h). I wish I could run 2+1 scheme, let's see.

AMD FX-8230 behaved very badly. Have to run only 4 cores of 8 and manually pin tasks to correct cores to assign one task per CPU "macroblock" (linux which I'm using cannot do this automatically).

This used to be less of a problem because I owned a working Q6600, and if I could comfortably do the tasks on that machine, then I was confident that most people could too. But it died. :(

The Q6600 is a good example of a fairly old but modern mid-to-low performance CPU and is, in my opinion, a good benchmark for the low end of challenge-capable CPUs. We need to make a point of checking with someone with an old machine like that when thinking about next year's challenges.

Along those lines, we have a 3-day TRP-LLR challenge in early October. I've got that listed as being about a 7 hour task on this computer. Looking at the database, there's 12 Q6600 tasks, the longest of which is a bit over 2 days and the shortest is a bit over 1 day. So we have a lot more margin with that challenge.

WOW there are already a lot of wu's for this challenge finished. I must be running dogs as I am not even close to being finished with one wu even on my two faster boxes...hummm.

Bear in mind that there are many participants with a veritable crunching farm of machines, some with the latest and greatest hardware and others with a room full of every old computer they've ever owned, all happily crunching away and heating up the living space.

Something just occurred to me, as I downloaded the new LLR app and wrapper in preparation for this challenge. Would it now be possible for WUs that don't entirely complete by the end of the challenge to get "partial credit" for their trickles? Perhaps losing that credit if they don't finish the WUs?


Thank you, Rick, for this idea. It's a really good suggestion, and I'm very much in favor of it.

Unfortunately, it's not going to happen.

There are some technical problems, but they're easy enough to solve and I've worked out most of the details. But there's two problems with such a system, and there are no easy solutions. Either problem by itself is a deal-breaker.

1) Fairness. The system is inherently unfair because the amount of partial credit each task would get depends on when the trickle happens. This is going to cause lots of complaints.

2) Cheating. This system would be very, very easy for someone to game by sending faked trickle messages. It would also be very difficult to detect such cheating.

As much as I liked the idea, it's dead in the water. Sorry.

WOW there are already a lot of wu's for this challenge finished. I must be running dogs as I am not even close to being finished with one wu even on my two faster boxes...hummm.

It looks like you are running all cores (HT enabled), this is a detriment to the work. Running half the cores (or HT disabled) could give you more than a 50% boost in speed.

The coding in the software really needs all the processing power it can. Doing two per core really causes them to swap in and out of the processor too often. Plus the size of these are also using a lot of room.

So try going 1/2 on your HT machines.

So try going 1/2 on your HT machines.

For LLR challenges, I recommend going into the BIOS and turning off Hyperthreading altogether. In my tests on Haswell, using 50% of the 8 threads made the CPU run significantly warmer compared to using 100% of 4 cores with HT turned off.

This may not make a difference if the cores are running at stock clocks, but if overclocked it very well might.

Not all motherboards allow you to turn hyperthreading off. But if yours does, you should turn it off when crunching LLR or Genefer.

I have a couple of water cooled boxes that are running about as fast as what is available CPU wise at low temperatures. Since there are no GPU's involved they must be doing something different as but I am not sure what it might be presently. Oh well I will sort it out...

Maybe the task duration times are greatly affected due to what hardware is used inside and outside a race. I think there are not many Q6600's left out in the field crunching LLR tasks aside a race. The few machines left doing it maybe highly tuned boxes, which are boosted to the max so that they're ready for the task. This could make the processor look much faster than it is on "normal" machines (un-oced all cores used). When these "normal" boxes are attracted by a race, they never can catch up with the tuned ones.

If I'm allowed to make a suggestion - I would prefer fewer challenges, but longer ones.

I have always been happy with my results in these races with the pc's I have until now.
This race has been a waste of my time as even my intel 4790K has not finished one set of tasks. Looks like most or all of my other pc's will not finish in time. I wish I had read the posts on this one earlier as I would have not participated in this race. This was my fault for not looking into this one better. I will complete these tasks and move on. I won't run a race like this one in the future as the complete time for the race is much too short. I am not willing to turn off hyperthreading or run a pc with only half the cores as this is a waste of my time. As I stated earlier this was my fault and I should not have even participated in this one.
Disappointed.

I have always been happy with my results in these races with the pc's I have until now.
This race has been a waste of my time as even my intel 4790K has not finished one set of tasks. Looks like most or all of my other pc's will not finish in time. I wish I had read the posts on this one earlier as I would have not participated in this race. This was my fault for not looking into this one better. I will complete these tasks and move on. I won't run a race like this one in the future as the complete time for the race is much too short. I am not willing to turn off hyperthreading or run a pc with only half the cores as this is a waste of my time. As I stated earlier this was my fault and I should not have even participated in this one.
Disappointed.


Your DC Haswell can complete these tasks in under 40 hours. (My non-DC Haswell, Core i5-4670K without overclocking, takes about 40 hours and you have a larger cache and a higher clock speed.) I've got about 12 more hours to go on the second set of tasks and I started the challenge almost half a day late.

You might want to look into why your computer hasn't finished yet. It should be fast enough to have done two sets of four by now.

I have a I5-4690K and yours appears to be running faster. You must be using faster ram. I am trying to figure out where my first 4 WU units went as they finished hours back but show at Primegrid to still be in progress. They are not waiting to upload so I am not sure where they are at presently.

They did not upload. I checked all four jobs and the upload files do not exist for any of them. They all appear to still be in progress. Take a look at the event log on your BOINC client and see what that says.

I have ram rated for faster speeds, but I lowered it to stock speeds at the beginning of the year after I started experiencing some instability. I'm running at 100% stock speeds now. AND this is my daily driver, so I'm running all sorts of things that steal CPU cycles from BOINC. Not sure what to tell you.

Gosh I wonder where the first 4 work units went for this window10_wfast box? I hope the next set do not disappear. I have never delved into the logs much but I did not see any sign of them on my box. The ones in progress are in my projects/www.primegrid.com folder. That is plain odd...

With jst under a day to go, it's time for the usual end of challenge reminder:

At the Conclusion of the Challenge

We would prefer users "moving on" to finish those tasks they have downloaded, if not then please ABORT the WU's instead of DETACHING, RESETTING, or PAUSING.

ABORTING WU's allows them to be recycled immediately; thus a much faster "clean up" to the end of a Challenge. DETACHING, RESETTING, and PAUSING WU's causes them to remain in limbo until they EXPIRE. Therefore, we must wait until WU's expire to send them out to be completed.

Michael one of your average Cullen WU took 138,630.76 seconds or 38.5 hours or so. Almost 2.5 times as fast as the 5280k of mine (349,090.39 seconds...96.969) which was running default clocks at 100%. and no other apps running. I checked a couple of others that have finished some and their time was similar to Michael's. What am I missing as far as setting this up to run under Windows a bit faster? Time Machine!

1 Cullen WU with a Intel(R) Core(TM) i7-5820K CPU took 349,090.39 seconds...96.969 or some hours. I thought that horse might run faster....


Looks like you have HT running. Running 6 instead of 12 at a time would be more than a 50% improvement in times. It isn't just that the HT is engaged, but with 12 units you are filling up even that larger Haswell-E cache. Your times would be closer to my E-1650 v3 Xeon that is running them in about 32 hours or so doing 6 at a time.

Scott, would similar advice be applicable with next month's challenge? Ample time to test and confirm.

Any time you're running LLR or Genefer (not just during challenges) you should turn off Hyperthreading. Only for sieves is hyperthreading advantageous.

It would be nice if they could make it like folding SMP work units. Where many cores work on just one work unit, not one core per one WU.
Think primegrid would ever go in that direction?
I don't know how hard it would be to program the project to do that, but it could bring in some multi socket servers in to a challenge like this.
I could not run my AMD 4 processor 48 core server this challenge. One core on its own is too slow to do one WU in time. But 48 cores all working on one WU could bang out WUs in time no problem.
Just some food for thought.

Their have been occasions where the authors of the various applications have tried it occasionally, but too much efficiency was lost trying to parallelize the application. It's therefore very unlikely to happen any time in the foreseeable future.

That's too bad, I know a couple folks with 4P that didn't get used or make the deadline.

On another note, my Xeon x5660 CPUs running overclocked to 4ghz on X58 boards finished 6 units each in 70-73 hours or so.
No AVX on those CPUs hurts their times.

Two or three weeks ago I tried my first Genefer WR and which was a huge disaster. I let it run for just over 4 hrs in my attempts to get an accurate estimate of total run time and I could not get it below 490 hrs.

I will go into the BIOS and turn off HT and try again over the next month or so.

Sorry, I should have been clearer. My comments about HyperThreading ONLY applied to programs running on the CPU. It's irrelevant for GPU programs, like the GFN-WR task you were running. (We will be starting GFN-WR tasks on the CPU in the near future, but as of right now it's GPU-only.)

Unfortunately, you have a fairly slow GPU (almost ANY mobile GPU can be considered "fairly slow" -- they're much slower than desktop GPUs despite having model numbers that sound similar), and that's probably about as good as you can get with that computer.

On the positive side, however, it's okay if you return the task a bit late. You'll still get credit most of the time. Furthermore, we'll be turning on our "deadline extension system" for GFN tasks in the near future, which means your laptop's deadlines will be extended, as needed, as long as it keeps working on the task (within reason, anyway.)

This of course assumes that the laptop is computing 24/7. If it takes 490 hours AND is only running 4 hours a day, you probably should only be running shorter tasks. :)

(I'm calling this a laptop because it's using a mobile GPU chip. Some desktop computers, such as "all-in-ones" and puck style computers use laptop parts. Even if your computer isn't a laptop, as far as the electronics are concerned it acts like a laptop.)

Scott, would similar advice be applicable with next month's challenge? Ample time to test and confirm.


Any time you're running LLR or Genefer (not just during challenges) you should turn off Hyperthreading. Only for sieves is hyperthreading advantageous.

Two or three weeks ago I tried my first Genefer WR and which was a huge disaster. I let it run for just over 4 hrs in my attempts to get an accurate estimate of total run time and I could not get it below 490 hrs.

I will go into the BIOS and turn off HT and try again over the next month or so.

Well, it's not as if the 660m was a good card anyway. My 970 takes around 100h, I imagine a mobile GPU from 3 gens older and from a lower series would do much, MUCH worst, regardless of HyperThreading.

In all honesty I wouldn't try Genefer-WR with that card. I would give it a shot at GFN "Short" or maybe the Manual Sieves.

The laptop is dedicated 24/7 .... glad to learn of the forthcoming CPU version of Genefer.

This is what I have done for the gold badge (GFN Short) and I am interested in the next badge in the series which obviously now means more GFN Short.

In the near future (i.e., probably a few weeks) we will be opening GFN searches on much smaller numbers. Those tasks will be a lot shorter.

Maybe because of this: http://www.primegrid.com/forum_thread.php?id=6135&nowrap=true#83276

For big tasks, using all 4 cores increases overall performance, but drastically decreases the individual performance of each WU. To put it another way: each WU takes longer to complete with all 4 cores active at once.

For those of you who have Nvidia GPUs in a Windows computer, are looking for something to do after the challenge is over, and don't mind getting your hands a little dirty with running some work manually from the command prompt, we are especially in need of some sieving for GFN 65536 and GFN 131072.

We're planning on opening up those two Genefer ranges with the new OCL2 and OCL3 apps, but we need to do more sieving first.

Manual sieving is run from the "Manual Sieving" link on the left side menu, or just click here: Manual Sieving.

Information about manual sieving can be found in this forum topic: http://www.primegrid.com/forum_forum.php?id=22

One more thought for those wanting to get their feet wet on GFN World Record tasks on either the gpu or the upcoming cpu app - I suggest running a few GFN short tasks and seeing if they get validated. If your machine isn't entirely stable for the shorter tasks, you want your computer to avoid getting an error after putting in many days of work on a World Record task.

FYI, it's officially no longer called "short" tasks. It's now the "GFN-21" project. The so-called short GFN tasks are now pretty huge -- they're crunching numbers 6 million digits in length, and rising rapidly. We'll have shorter GFN projects available in the not too distant future, but for now your choices of GFN sizes are "Humongous" and "Even Bigger". :)

One more thought for those wanting to get their feet wet on GFN World Record tasks on either the gpu or the upcoming cpu app - I suggest running a few GFN short tasks and seeing if they get validated. If your machine isn't entirely stable for the shorter tasks, you want your computer to avoid getting an error after putting in many days of work on a World Record task.


FYI, it's officially no longer called "short" tasks. It's now the "GFN-21" project. The so-called short GFN tasks are now pretty huge -- they're crunching numbers 6 million digits in length, and rising rapidly. We'll have shorter GFN projects available in the not too distant future, but for now your choices of GFN sizes are "Humongous" and "Even Bigger". :)

Is that "20h average" accurate, or is it a remain of the older not-as-short-but-shorter tasks?

Looking at that page, it's saying 20 hours on the CPU and 3.5 hours on the GPU, and those are clearly n=19 numbers. Figure on about 16 hours for a reasonably fast GPU and 72 hours for a Haswell FMA3 CPU task and a minimum of about 130 hours for anything that doesn't have AVX.. All those numbers are based on a single task running with the computer otherwise idle, so the times will be higher if all the cores are running.

The times on that page will take a little while to adjust. It averages the times of the last 1000 validated results, and we're still getting residual n=19 results trickling in -- probably more than the n=21 results. Also, those numbers are only calculated once a day.

The challenge is over!

Final statistics:

Challenge: Reign Record
App: 4 (CUL-LLR)
(As of 2015-09-15 18:00:45 UTC)

15167 tasks have been sent out. [CPU/GPU/anonymous_platform: 15134 (100%) / 0 (0%) / 33 (0%)]

Of those tasks that have been sent out:

5371 (35%) came back with some kind of an error. [5371 (35%) / 0 (0%) / 0 (0%)]
5517 (36%) have returned a successful result. [5490 (36%) / 0 (0%) / 27 (0%)]
4279 (28%) are still in progress. [4273 (28%) / 0 (0%) / 6 (0%)]

Of the tasks that have been returned successfully:

2182 (40%) are pending validation. [2165 (39%) / 0 (0%) / 17 (0%)]
3251 (59%) have been successfully validated. [3241 (59%) / 0 (0%) / 10 (0%)]
5 (0%) were invalid. [5 (0%) / 0 (0%) / 0 (0%)]
79 (1%) are inconclusive. [79 (1%) / 0 (0%) / 0 (0%)]

The current leading edge (i.e., latest work unit for which work has actually been sent out to a host) is n=13916933. The leading edge was at n=13676807 at the beginning of the challenge. Since the challenge started, the leading edge has advanced 1.76% as much as it had prior to the challenge!

We normally do about 150 Cullen tasks a day, and over 1000 per day were returned during the challenge. Nearly as many additional tasks are still being processed. Well done everyone!

... and the cleanup begins!

I expect the cleanup to take about 45 to 90 days to complete. Mostl likely somewhere in the middle of that range.

Cleanup Status:

Sep-15: Reign Record: 2259 tasks outstanding; 2259 affecting individual (234) scoring positions; 1669 affecting team (52) scoring positions.

Apologies in advance as my Q6600 box has two inconclusive units. So either the box is bad (it was fine previously so I didn't check recently) or I had bad luck to be paired up with two bad wingmen. Given I have known problems with my other Q6600, I suspect it is me. Has LLR changed much in say the last year that may stress boxes even more than they have in the past? I really should retire those Q6600s... or maybe just sieve a bit.

No, the changes to LLR generally are all about making use of the latest instruction set extensions, such as AVX and FMA3. This has no affect on Core2 CPUs.

Electronics do age, however, so it's not unheard of for once stable computers to become less so as time goes on. And, of course, you should get rid of the dust inside. "Intel Inside" == good; "Dust Inside" == bad. :)

I'll check on those 2 tasks and see if it's obvious which one is faulty...

... and, unfortunately, it's your Q6600 that appears to be faulty in both of those tasks.

In both cases, it detected an error in the calculations, restarted from the last checkpoint file, and then continued without further detecting an error. Meaning it did the same part of the calculation twice with different results each time. It's time to either figure out why that's happening and correct the problem (if possible), or retire it from primality testing. Sieving is a lot less stressful and it may be able to do that without error. But if you can't find and correct the problem, its LLR-crunching days are probably over.

On the other Q6600 box I found reducing the ram speed seems to have resolved its problems, but I haven't done much testing on it. The speed penalty was ~5% for PPS or was it mega I was testing on? This box was still on the higher ram speed so maybe same applies here. Had I lowered the ram speed, it wouldn't have completed in time for this challenge anyway.

Something just occurred to me, as I downloaded the new LLR app and wrapper in preparation for this challenge. Would it now be possible for WUs that don't entirely complete by the end of the challenge to get "partial credit" for their trickles? Perhaps losing that credit if they don't finish the WUs?


Thank you, Rick, for this idea. It's a really good suggestion, and I'm very much in favor of it.

Unfortunately, it's not going to happen.

There are some technical problems, but they're easy enough to solve and I've worked out most of the details. But there's two problems with such a system, and there are no easy solutions. Either problem by itself is a deal-breaker.

1) Fairness. The system is inherently unfair because the amount of partial credit each task would get depends on when the trickle happens. This is going to cause lots of complaints.

2) Cheating. This system would be very, very easy for someone to game by sending faked trickle messages. It would also be very difficult to detect such cheating.

As much as I liked the idea, it's dead in the water. Sorry.


I've been giving this idea some thought, and I think there's a way to do this without relying entirely (or at all) on the 'trickle' ...

Since a task must always be submitted - and eventually verified - in order to count for a challenge score, could you not calculate the 'eligible' time for a late task to be the minimum (cpu) time the task took overall, minus the time from end of challenge to task submission.
This effectively bases the partial score on the assumption that the task started as late as possible and ran with perfect efficiency until submission, giving the lowest possible effective time the task could have been running during the challenge.
This would 'fairly' penalize all late tasks to the same degree without the need to rely on the timing (or validity) of trickle messages..??

It may still be theoretically possible to cheat this system by faking both trickle messages and CPU times, but it would still require the tasks to be crunched within the requisite time during and after the challenge, possibly by faster computers, so I can't believe it would be worth the effort, and should be fairly easy to spot!
You could also perhaps require any challenge entrant to continue (cleanup!) work on ALL computers until all tasks, downloaded before the last 'late' task is submitted, have been completed and returned as well.. - just to ensure any faster computers used during the challenge are not used to 'help' with the slower tasks..!

Estimating how fast a computer "should" run is incredibly difficult. You would not believe how much effort went into modeling the LLR tasks so we could figure out how fast one computer should be able to run each task. Figuring it out generically is next to impossible.

LOL I might not be that observant but this sure sounds a lot like an a "royal" statement. Of course I'm just messing with ya Steve.

However in all honesty I do not believe for a moment that a requirement to continue work on a challenge project after it is done would ever fly.

The true beauty of all of this is the fact that we as volunteer crunchers are encouraged to participate in all facets of PG but given the freedom to choose how we do that.

It has worked well enough through voluntary cleanup. I try to continue cleanup work for the equivalent length of the challenge itself, but at a less extreme rate (reduced overclocking or fewer cores). Sort of like a cooldown lap :/

I've been giving this idea some thought, and I think there's a way to do this without relying entirely (or at all) on the 'trickle' ...

Since a task must always be submitted - and eventually verified - in order to count for a challenge score, could you not calculate the 'eligible' time for a late task to be the minimum (cpu) time the task took overall, minus the time from end of challenge to task submission.
This effectively bases the partial score on the assumption that the task started as late as possible and ran with perfect efficiency until submission, giving the lowest possible effective time the task could have been running during the challenge.

It may still be theoretically possible to cheat this system by faking both trickle messages and CPU times, but it would still require the tasks to be crunched within the requisite time during and after the challenge, possibly by faster computers, so I can't believe it would be worth the effort, and should be fairly easy to spot!
You could also perhaps require any challenge entrant to continue (cleanup!) work on ALL computers until all tasks, downloaded before the last 'late' task is submitted, have been completed and returned as well.. - just to ensure any faster computers used during the challenge are not used to 'help' with the slower tasks..!

I don't know if this is what you thought of, but here's my suggestion (based on yours).

*Assuming we have the task was sent during the challenge (so it would be ellegible to get credit), and it was sent and validated AFTER the challenge period (so one can't get full credit for the task),

First, take T = (CPU Time) - (Time since the end of the challenge). If T<= 0, it would mean that you either started the task after the challenge was over, and thus shouldn't be awarded challenge points, or you did start before the end of the challenge, but returned the task so much later that you don't even deserve your challenge points (same idea as a "no quick return bonus").

We use CPU time here to ignore efficiency. For example, if my CPU shared resources with rendering a video, the elapsed time would go up, but CPU time would (in theory) remain the same.

-For a cruncher, even an uber slow computer would be rewarded some points, as CPU Time would be aproximately equal to Elapsed time, and thus T > 0 (unless starting at the very last second before the end of the challenge.

-For a 24/7 (so no pausing the tasks) cruncher that is also used as a daily driver (and thus Elapsed is considerably bigger than CPU), it would still get some reward, provided it didn't start at the last few hours of the challenge. With a task starting around 1d before the end of the challenge, it's extremely unlikely that difference in times would be that big, assuming just usual web browsing and light apps. I can only see it becoming that big of a difference if:
A- it was being used along a CPU hungry app, such as a game / render, but then you aren't dedicating yourself to the challenge, and thus you aren't worthy of being rewarded the extra;
B- the computer is REALLY slow. Like my Pentium E2180 daily driver 24/7 cruncher: it's doing EPS tasks (which aren't THAT big), currently at 35% and difference is at 8h already, so I estimate about 1d difference once the task complete. In this B cenario, though, we could make the argument that you took SO LONG to finish the task (remember, slow PC case), that you also shouldn't get a challenge bonus.

Last, T < 0 is also likely to happen if you don't crunch 24/7 (say, you turn your PC / Boinc off). In that case, it's once again very justifiable to say "you are not dedicating yourself to the challenge, and thus shouldn't be awarded".


Next,
if T > 0, it's likely that you did help during the challenge, but you weren't able to complete it in time. In that case, we calculate C = T / (CPU Time). It's easy enough to see that C is always lower than 1, as the upper number is the same as the lower one (sorry, don't know the math names in English...), minus something.

Challenge credit would be (WU Normal Credit)*C.

If the task is sent just a little bit over the challenge period, the time passed would be very small, and thus C would be very close to 1. The member would end up getting almost the full credit for the job, but not just quite 100% of it, as it went a little late.

This also adresses the problem with CPU resources being stolen by other apps. Suppose the exact same task was sent late with 100% CPU efficiency. We would a certain C. Now, if the CPU had to share time with something else, CPU Time would be the same, but the (Time since the end of the challenge) would be higher, and thus C would be lower. As fair as possible: you take longer to finish and didn't dedicate as much as possible, so you don't get as much credit, though you still get some.



This would have the benefits of not relying on the trickle system, and relying only on CPU Elapsed time, which would be extremely hard to cheat (I think?) and on a physical timer that would be calculated by the server, which is in control of Primegrid, so no cheating there as well.

Starting many WUs during the challenge and pausing them would be useless, as the time passed would just outweight CPU Time, causing a very small T or T<0. Running more tasks than the number of threads in your PC would increase elapsed time, but CPU time would stay constant (I think?), so it should easly cause T<0.

The only "iffy" cenario would be HT, where it would increase CPU time. However, it would also increase Time passed by a lot, so it should never cause T < 0, while still causing a small C. That's good, as it provides better rewards for people that know HT is harmful for the research and turn it off, but without punishing casual people that help the project, but don't know much about it (and non tech savy people).

So there you have it, this is my "Partial Challenge Credit" suggestion, throughtfully broken down into tiny pieces to help analysiz and implementation. Feel free to criticize, as I obviously think the methodology is perfect (otherwise I'd have fixed the problems already) ;)

I'm not sure what you mean by "CPU elapsed time", as "CPU time" and "elapsed time" are two different things. Assuming you meant "CPU time", then no, that's trivially easy to fake, sorry. Anything coming from the host computer must be assumed to be falsified if you're thinking about how the system can be cheated. The only thing you can be sure of is that the host actually completed the work if it returned the correct results.

You could also perhaps require any challenge entrant to continue (cleanup!) work on ALL computers until all tasks, downloaded before the last 'late' task is submitted, have been completed and returned as well.. - just to ensure any faster computers used during the challenge are not used to 'help' with the slower tasks..!


LOL I might not be that observant but this sure sounds a lot like an a "royal" statement. Of course I'm just messing with ya Steve.

However in all honesty I do not believe for a moment that a requirement to continue work on a challenge project after it is done would ever fly.

The true beauty of all of this is the fact that we as volunteer crunchers are encouraged to participate in all facets of PG but given the freedom to choose how we do that.

Cheers Rick



I Hereby Decree.... :)

... that this would most definitely NOT be a 'requirement' - but merely a 'suggestion' for those who intend to obtain plenty of 'late' credits and would like to provide 'proof' that these credits were not fraudulently obtained by running 'slow' tasks on 'fast' computers after the challenge!

While it's clearly possible to fake the CPU time in a reply, it can only be increased to the point where it's just less than the overall time from download to report of a task.. which wouldn't gain much extra credit at all, since under normal challenge conditions, this difference is generally quite small anyway!

Our cheater would need to download a whole heap of extra challenge tasks at the start, then crunch them all as quickly as possible on his fastest computers at the end of the challenge, before editing and submitting them with all valid data apart from faked CPU times to make them look like they have been crunching slowly all thru the challenge... all to gain an extra (smallish) percentage of challenge credits? I reckon anyone prepared to go to so much effort to fraudulently gain an extra place or two on the rankings is welcome to it, as I'm sure it would be far easier to make up that difference in an honest way..!

This would have the benefits of not relying on the trickle system, and relying only on CPU Elapsed time, which would be extremely hard to cheat (I think?)


I'm not sure what you mean by "CPU elapsed time", as "CPU time" and "elapsed time" are two different things. Assuming you meant "CPU time", then no, that's trivially easy to fake, sorry. Anything coming from the host computer must be assumed to be falsified if you're thinking about how the system can be cheated. The only thing you can be sure of is that the host actually completed the work if it returned the correct results.

Okay.... mission aborted, abandon the ship....

Anyway, the server can tell us "Sent time", "Reported time", "Original Deadline (without the extensions allowed by the trickle system)" and "End (of challenge) time". Those are all server based, so they would be trusty, no?

So here's another approach.

We first make ELAPSED = (Report time) - (Sent time).

Next, we call OVERDUE = (Report time) - (End time).

Be T = OVERDUE / ELAPSED

Finnaly, we make C = 1 - T.

This makes it so that, as long as you download the WU during the challenge, you will get some credit for it. ELAPSED starts out much bigger than OVERDUE, so in the beginning, C is very close to 100% credit. However, as time passes, OVERDUE catches up (same idea as Lim n/n+1), and C get's close to no credit at all. So the faster you return a task, the better. Downloading many WUs and let them overdue still remains a very bad idea.

To prevent abuse, we have to limit how many tasks will get credit this partial credit. Otherwise, one would just get max possible ammount of WUs, keep them alive via trickle system, and thus get that little bit extra credit, while making cleanup work a nightmare.

For that, a few propositions:
1- Each computer get's one "set" of extra work. Ex: if I have a quad core PC, I can get partial credit for up to 4 tasks reported by that computer.
2- A fixed cap per computer. Say, 1 extra task per PC, regardless of cores.
3- A fixed cap per host, regardless of number and type of machines

Assume for a second that you're correct that this can't be gamed -- this system awards the minimum theoretically possible challenge credit to people who miss the end of the challenge. Now you have people crunching and not get credited in the challenge for it -- and not understanding why because the system is too complex.

Besides, this is the "PrimeGrid Challenge Series", not the "PrimeGrid Everyone Who Participates Gets a Trophy Like the Kids in Little League Series". Part of the challenge is getting the tasks returned in time.

I'm not interested in building an overly complicated system to replace one that's worked well for half a decade. To be worth doing, the benefit needs to outweigh the cost. This doesn't. Cost doesn't just mean "how long it takes to program". Users need to be able to easily understand where their scores come from, and this system is something we'll be explaining during each and every challenge because the numbers that go into creating the scores won't be easily visible.

Users need to be able to easily understand where their scores come from, and this system is something we'll be explaining during each and every challenge because the numbers that go into creating the scores won't be easily visible.

I'm sorry, but I don't think that's a valid argument. Understanding the mathematics described in the project's descriptions is, (at least to me) A LOT HARDER than understanding a very small formula that only uses the 4 basic operations. It would be very hypocritical to demand a new system to be easily understandable to be implementing, but not demanding the same for launching a new subproject.

I bet a pretty large chunck (if not the majority) of our userbase crunches for projects they have no idea how it works. And for the rest of the ones that do have a grasp at how projects work, I'm 100% sure they would be able to understand this new credit system, if they really wanted to.

The "ain't broke, don't fix it" argument is valid one to me, but the "ease to understand" is not.

I don't see a need for partial credit during challenges. The fun lies in completing x number of tasks using each computer's specific hardware in the time allotted.

Isn't that the reason for having a beginning and ending date for a challenge?

EDIT: I've read the comments and I'm trying to understand the reasons for its implementation, but I'm just not feelin' it ;)

Feel free to continue discussing this to your heart's content, and I'll be reading it, but understand as far as I'm concerned it's dead and I won't be putting any more thought into it. Unless you have a truly great inspirational idea I'm done with this idea. Got bigger fish to fry. It was a good idea worth discussing, but it isn't going to work.

I don't know if it extending the time by a few hours (or days for tougher subprojects) for any given challenge is agreeable or desirable by the staff, but would that satisfy those who might have a computer that struggles to finish one or two tasks?

Personally, I like the sweating and nail-biting that occurs in the dwindling last few hours of a challenge. Will the tasks finish on time? Does it look like I have time for just one more task?

I don't know if it extending the time by a few hours (or days for tougher subprojects) for any given challenge is agreeable or desirable by the staff, but would that satisfy those who might have a computer that struggles to finish one or two tasks?

Personally, I like the sweating and nail-biting that occurs in the dwindling last few hours of a challenge. Will the tasks finish on time? Does it look like I have time for just one more task?


For every minute/hour/day you make a challenge longer you will allow more units to be finished, but there's always that next group of users who will just miss the deadline by an hour or so. So no, extending challenges is no solution for the general problem. I will however look into challenge length/work unit length when drawing up the new schedule.

I completely agree, this is what makes the long task challenges special. If your timing is bad, you may lose a significant amount of time, but one WU can already make a difference even in the upper parts of the ranking.

After the challenge I hooked up 1 Cullen WU with the I5-4690K and it is looking like 24 hours with a single core pulling.

Two more inconclusive results, but more worryingly, from my new Skylake box. Any ideas? It was doing 4 units in about a day. The two inconclusive results were in the same batch, but the other 2 units in that batch were ok. No other problems before or after that. I think I did shut down that box during that set of units as I wanted to move a storage hard disk out, but I gracefully exited from Boinc before doing so. The wingmen on those inconclusive units don't appear to have any problems.

More worryingly I'm running SoB on that system right now...

One of them is almost certainly bad (something like 99.99999999% certainty it's bad, but not quite 100%). The other one it's impossible to tell which is bad.

One thing you might want to try is take the machine offline for a day, and manually run both of those tests again to see if you get the same result. (I can provide the original results from your computer to you privately.) If you get a different result when rerunning the test, you definitely have a problem. If you get the same result -- and that result turns out to be wrong -- it could conceivably be a problem with LLR.

Testing on SOB cpu run times. I tested and got 101.52hrs for one wu using one core no HT with the I5-4690K and 103.23hrs for one wu using one core no HT with the I7-5820K. Oddly the I5 was faster by a narrow margin..


That i5 has higher CPU clock so, if not limited elsewhere, it would be expected to be faster than that i7 when running a single task. But it is limited elsewhere... a single Cullen unit wont fit inside the i5's cache, but can fit inside that i7's, giving the i7 an advantage.

When we move to SoB, the units are too big to fit inside even that i7's cache, so we're back to hitting ram on both processors at some point. Here I don't have enough info on the ram configuration (speed, channels) to make an informed guess. If the i7 was running same speed ram in dual channel mode like the i5, then the i5's higher clock could give it the advantage (assuming the bigger cache of i7 doesn't help). If the i7 is running quad channel it would have higher bandwidth, and it is harder to say what happens in that case since I don't know the relative balance of CPU vs. ram bandwidth impacting the overall speed.

If you run 3 or 4 units at the same time, it will become much more ram bandwidth limited and I'd expect the i7 running quad channel ram to be faster in that case.

The WU on your I7 (648903721) was smaller than the WU on the I5 (648916119). But the I7 has a lower processor frequency so both times are nearly the same.

Good catch there with the different FFT sizes. It makes a difference.

All things being equal, the difference in FFT size by itself will account for a 7.3% longer run time on the larger FFT. The reference benchmark speed for the 2400K FFT is 16.314 ms/iteration and the 2560K FFT is 17.518 ms/iteration.

"Your Mileage May Vary", of course. The benchmarks are done on a Core-i5-4670K at stock speed with dual channel DDR3 memory, also at stock speed, while running 4 tasks simultaneously.

1 Cullen WU with a Intel(R) Core(TM) i7-5820K CPU took 349,090.39 seconds...96.969 or some hours. I thought that horse might run faster....


Looks like you have HT running. Running 6 instead of 12 at a time would be more than a 50% improvement in times. It isn't just that the HT is engaged, but with 12 units you are filling up even that larger Haswell-E cache. Your times would be closer to my E-1650 v3 Xeon that is running them in about 32 hours or so doing 6 at a time.



I am trying 6 Cullen wu's on the I7-5820K with 6 cores no HT to see if it compares with your Xeon. Their architecture seems to be similar

Looks like I am headed to around 46 hours for 6 WU's so the Xeon is a bit faster for unknown reasons (more hardware registers etc.) as the cache is the same and ram is probably close (mine running 2133).

1 Cullen WU with a Intel(R) Core(TM) i7-5820K CPU took 349,090.39 seconds...96.969 or some hours. I thought that horse might run faster....


Looks like you have HT running. Running 6 instead of 12 at a time would be more than a 50% improvement in times. It isn't just that the HT is engaged, but with 12 units you are filling up even that larger Haswell-E cache. Your times would be closer to my E-1650 v3 Xeon that is running them in about 32 hours or so doing 6 at a time.



I am trying 6 Cullen wu's on the I7-5820K with 6 cores no HT to see if it compares with your Xeon. Their architecture seems to be similar


Looks like I am headed to around 46 hours for 6 WU's so the Xeon is a bit faster for unknown reasons (more hardware registers etc.) as the cache is the same and ram is probably close (mine running 2133).


I just checked the last Cullen work units to run on the Xeon and they are about 33 hours (1440k FFT size). That FFT size could make a very big difference if the units you completed are using a larger FFT.

My RAM is also 2133, but I think your clock might be a little higher. That said, the Xeon and i7 may turbo mode differently, which might produce some difference also.

I am not clear on the FFT size issue. Can you fill me in please...
