! ! ! URGENT WARNING Re: Task Bunkering ! ! !

This subproject uses LLR2, which means dumping bunkers will be disastrous for the server. It will fill up the server's disk drive. That's really bad.

As a result, the server will stop accepting uploads. That will be bad for all users, of course, but it will be worse for the people who have been holding bunkers. You may miss out on uploading your entire bunker if we shut down uploads. The end result is that if we have to protect the server, people who are bunkering will be severely disadvantaged.

So we're asking everyone who has been bunkering tasks for our challenges to not do so in any challenge where we're using LLR2. This is to protect our ability to keep the server running during the challenge. But it's also in your best interest: you'll be the people hurt the most if uploads get suspended.

TL;DR: This will be our first LLR2 challenge, so please, please, please refrain from bunkering. Thank you!!!

That being said...



Welcome to Évariste Galois's Birthday Challenge!

The seventh challenge of the 2020 Series will be a 5-day challenge celebrating the 209th birthday of Évariste Galois, French mathematician and political activist. The challenge will be offered on the PPS-DIV (LLR) application, beginning 20 October 06:00 UTC and ending 25 October 06:00 UTC.

Évariste Galois (25 October 1811 – 31 May 1832) was a French mathematician and political activist. While still in his teens, he was able to determine a necessary and sufficient condition for a polynomial to be solvable by radicals, thereby solving a problem standing for 350 years. His work laid the foundations for Galois theory and group theory, two major branches of abstract algebra, and the subfield of Galois connections. He died at age 20 from wounds suffered in a duel.

For more about the life of Galois, check out this fantastic biography: https://mathshistory.st-andrews.ac.uk/Biographies/Galois/
Also stay tuned for the biopic starring Timothée Chalamet! (not really)

To participate in the Challenge, please select only the Fermat Divisor Search LLR (PPS-DIV) project in your PrimeGrid preferences section.

Note on LLR2 tasks: LLR2 has eliminated the need for a full doublecheck task on each workunit, but has replaced it with a short verification task. Expect to receive a few tasks about 1% of normal length.

Application builds are available for Linux 32 and 64 bit, Windows 32 and 64 bit and MacIntel. Intel and Zen2-based AMD CPUs with FMA3 capabilities (Haswell, Broadwell, Skylake, Kaby Lake, Coffee Lake, and Ryzen 3rd gen) will have a very large advantage, and Intel CPUs with dual AVX-512 (certain recent Intel Skylake-X and Xeon CPUs) will be the fastest.

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. Tasks on one CPU core will take about 2.5 hours on fast/newer computers and 5 hours+ 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. :)

Highly overclocked Haswell, Broadwell, Skylake, Kaby Lake or Coffee Lake (i.e., Intel Core i7, i5, and i3 -4xxx or better) computers running the application will see fastest times. Note that SGS is running the latest AVX-512 version of LLR which takes full advantage of the features of these newer CPUs. It's faster than the previous LLR app and draws more power and produces more heat. If you have certain recent Intel Skylake-X and Xeon CPUs, especially if it's overclocked or has overclocked memory, and haven't run the new AVX-512 LLR before, we strongly suggest running it before the challenge while you are monitoring the temperatures.

Please, please, please make sure your machines are up to the task.


Multi-threading is supported and IS recommended.

Those looking to maximize their computer's performance during this challenge, or when running LLR in general, may find this information useful.


  • Your mileage may vary. Before the challenge starts, take some time and experiment and see what works best on your computer.
  • If you have a CPU with hyperthreading or SMT, either turn off this feature in the BIOS, or set BOINC to use 50% of the processors.

    • If you're using a GPU for other tasks, it may be beneficial to leave hyperthreading on in the BIOS and instead tell BOINC to use 50% of the CPU's. This will allow one of the hyperthreads to service the GPU.


  • The new multi-threading system is now live. Click here to set the maximum number of threads. This will allow you to select multi-threading from the project preferences web page. No more app_config.xml. It works like this:

    • In the preferences selection, there are selections for "max jobs" and "max cpus", similar to the settings in app_config.
    • Unlike app_config, these two settings apply to ALL apps. You can't chose 1 thread for SGS and 4 for SoB. When you change apps, you need to change your multithreading settings if you want to run a different number of threads.
    • There will be individual settings for each venue (location).
    • This will eliminate the problem of BOINC downloading 1 task for every core.
    • The hyperthreading control isn't possible at this time.
    • The "max cpus" control will only apply to LLR apps. The "max jobs" control applies to all apps.


  • If you want to continue to use app_config.xml for LLR tasks, you need to change it if you want it to work. Please see this message for more information.
  • Some people have observed that when using multithreaded LLR, hyperthreading is actually beneficial. We encourage you to experiment and see what works best for you.



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 at the very top, above the countdown clock.

Scoring Information

Scores will be kept for individuals and teams. Only tasks issued AFTER 20th October 2020 06:00 UTC and received BEFORE 25th October 2020 06:00 UTC will be considered for credit. We will be using the same scoring method as we currently use for BOINC credits. 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.

At the Conclusion of the Challenge

    We kindly ask users "moving on" to ABORT their tasks instead of DETACHING, RESETTING, or PAUSING.

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

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


About the Fermat Divisor Search

In mathematics a Fermat number, named after Pierre de Fermat who first studied them, is a positive integer of the form Fn = 22n+1, where n is a nonnegative integer.
The first few Fermat numbers are 3, 5, 17, 257, 65537, 4294967297, 18446744073709551617, … (sequence A000215 in the OEIS).

Only five Fermat primes are known, and the Fermat numbers grow so quickly that it may be years before the first undecided case: F33 = 2233+1 is shown prime or composite - unless we luck onto a divisor. Ever since Euler found the first Fermat divisor (divisor of a Fermat composite), factorers have been collecting these rare numbers.

The largest known prime Fermat divisor is the megaprime 13 * 25523860+1, discovered by PrimeGrid this January, which divides F5523858 = 225523858+1. Will we break this record during the challenge?

Euler showed that every divisor of Fn (n greater than 2) must have the form k*2n+2+1 for some integer k. For this reason, when we find a large prime of the form k*2n+1 (with k small), we usually check to see if it divides a Fermat number. The probability of the number k*2n+1 dividing any Fermat number appears to be 1/k.

Any prime Generalised Fermat Number Fb,n = b2n+1 (with b an integer greater than one) is called a generalised Fermat prime (because they are Fermat primes in the special case b=2), Ribenboim (1996).
Riesel (1994) further generalised by defining Extended Generalised Fermat Numbers xGFn,a,b = a2n+b2n.

In the Fermat Divisor Search we focus on special k's that are either small (generally gives high chance of dividing a Fermat number) or have special properties that makes them attractive.
First we searched k=19683 up to n=4M, (now complete).
Then we searched five additional k's, 1323 (even n only), 2187 (even n only), 3125, 3267 (even n only) and 3375, up to n=3.322M, (now complete).
Finally, we're currently searching 5<=k<=49 up to n=9M.

What is LLR?

The Lucas-Lehmer-Riesel (LLR) test is a primality test for numbers of the form N = k*2^n − 1, with 2^n > k. Also, LLR is a program developed by Jean Penne that can run the LLR-tests. It includes the Proth test to perform +1 tests and PRP to test non base 2 numbers. See also:



What is LLR2?

LLR2 is an improvement to the LLR application developed by our very own Pavel Atnashev and stream. It utilizes Gerbicz checks to enable the Fast DoubleCheck feature, which will nearly double the speed of PrimeGrid's progress on the projects it's applied to. For more information, see this forum post.

Highly overclocked Haswell, Broadwell, Skylake, Kaby Lake or Coffee Lake (i.e., Intel Core i7, i5, and i3 -4xxx or better) computers running the application will see fastest times.

So, which is it? Use Multi-threading or not? Sounds contradictory to me.

I'm guessing you you just copied and pasted from previous challenges but don't know.

My mistake. Sorry. I often get the two confused.

I don't suppose there would be any way possible to get the short "proof" tasks to run on hyperthreads would there?

Or to only get the "proof" tasks? I've still got to read the thread about LLR2 to learn more about it.

1.BOINC automatically uses all the threads available, which includes hyperthreads.
2.Alas, that's not possible. I'd really like another subproject with all the proof tasks but I don't think it'd be realistic. Probs I'd be the only one crunching them. ;)

It seems that a new world record Fermat divisor has been found outside PrimeGrid. 7*2^18233956 + 1 divides F(18233954). Prime found by Ryan Propper, divisibility of a Fermat number apparently found by Serge Batalov.

After this, our PPS-DIV project is only capable of finding the 2nd largest Fermat divisor.

Bunkering is holding onto many results - so to then upload them at once - the motivation to do this is it may hide how many tasks you have done until you upload them - a challenge strategy.
As far as I know downloading many tasks at once is fine.
Edit: I think bunkering may more accurately be described as making a choice to hold onto results rather than sending them back as they are finished. Some people may not have an internet connection 24/7 and may not be able to always send back results exactly when finished - this is necessity.

When you download only one task at a time, and return the task as soon as you can, you are doing the right thing!

But note that after LLR2 has come to PPS-DIV, your 1st percentage will always be 100, no matter what you do.

Bunkering could be downloading many tasks early, instead of downloading tasks "continuously" during the five days. The worst thing people could do would be to hold back the tasks they have already finished, with the intention of uploading everything in the last minute before the challenge ends. That might bring down the server.

So do not download too many tasks, and be sure to upload continuously as you finish your tasks.

I'm not trying to be mean or rude, but did you tell the whole world your server(s) have essentially a DoS vulnerability? Maybe fix the issue rather than plead the community to do the right thing, which I'm sure they will. However with that said, there are always malicious people out there. If there wasn't we wouldn't have Cyber Security.

I understand the resources required for a malicious person to submit enough bunkered tasks to fill the storage on your computing resources, but it could happen. How can the community help fix this problem? We need to buy more storage? Maybe I don't fully understand the issue here.

1.BOINC automatically uses all the threads available, which includes hyperthreads.
On software side, is there even a difference between a hyperthread and a normal thread? Hyperthreading just means two threads run on the same core using a scheduler. But it's not like one is a hyperthread, the other isn't.

That means as long as HT is on, even if BOINC is set to use only 50% of available CPUs, there will still be threads running alongside BOINC threads on the same core. That's not a bad thing per se, as the OS needs to run other tasks and HT allows to do that efficiently.

It's only a bad thing if the same task is split into so many threads that more than one thread of the same task runs on the same core.

1.BOINC automatically uses all the threads available, which includes hyperthreads.
On software side, is there even a difference between a hyperthread and a normal thread? Hyperthreading just means two threads run on the same core using a scheduler. But it's not like one is a hyperthread, the other isn't.

Not quite. Hyperthreading is a hardware resource - it duplicates the CPU registers of a core to allow 2 (software) threads to maintain execution state on the same core. A core contains a set of diverse hardware execution units - instruction decoder, floating point and integer ALUs, barrel shifter, address computation, etc. arranged in a pipeline to overlap different stages of hardware instruction execution. The execution units use data in registers and it takes time and consumes L1 cache bandwidth to transfer data between the L1 cache and the CPU registers. During these transfer times a thread's execution stalls and parts of the pipeline become idle. The second set of registers in a core allows the CPU to have alternate work available for execution to reduce the idle time of the core's execution units. To software and the O/S, it looks like 2 CPU cores are available, but in hardware the core is just sequentially switching between a pair of threads. Only one thread at a time is being actively "worked on" by the core while the other thread is waiting for data to be moved. So HT is really a trick to reduce demand on L1 cache bandwidth and reduce core idle time.

That means as long as HT is on, even if BOINC is set to use only 50% of available CPUs, there will still be threads running alongside BOINC threads on the same core. That's not a bad thing per se, as the OS needs to run other tasks and HT allows to do that efficiently.

Correct. PrimeGrid tasks are CPU intensive so the point of limiting BOINC threads is to reduce demand on shared resources, especially per-core cache. LLR tasks use long arrays of numbers which have to be moved between the CPU and memory.

It's only a bad thing if the same task is split into so many threads that more than one thread of the same task runs on the same core.

I disagree. A thread runs more efficiently if it is able to use data already found in the per-core cache. If a task flushes data from cache which is being used by it's co-resident alter-thread, that's a bad thing. This comment applies to any thread.

One acceleration strategy is to use CPU affinity to confine all non-BOINC tasks to a single core so that the BOINC work's cache is undisturbed. You will get less BOINC work done on that core and everything else will also run more slowly, but all the other cores will be fully busy with BOINC work. But O/S tasks are so limited in their CPU requirements compared to LLR that their CPU utilization is very low. The gains for BOINC are really by confining threads that consume CPU without doing much, like running javascript in a web browser (if your system is not dedicated to BOINC work).

It depends on what you mean by “software”. Normally, apps don’t know the difference, but the operating system does. The OS should try to use hyperthreads last in order to maximize performance.

But even some apps are cognizant of hyperthreading and will try to use real threads first.

When I say “real thread” I mean restricting usage to only one of the two hyperthreads. There’s no actual difference between one and the other. You just want to avoid using both of them at the same time if there’s other cores available.

Not quite. Hyperthreading is a hardware resource - it duplicates the CPU registers of a core to allow 2 (software) threads to maintain execution state on the same core.
Doesn't that amount to the same? There is no such thing as a hyperthread, just the mechanism of hyperthreading. The threads only see the emulated/duplicated registers.

I disagree. A thread runs more efficiently if it is able to use data already found in the per-core cache. If a task flushes data from cache which is being used by it's co-resident alter-thread, that's a bad thing. This comment applies to any thread.
But even if the data is still there for the other thread, isn't there a loss of efficiency due to overhead? Say you have two physical cores, what would be the advantage of running four threads on it instead of two?

One acceleration strategy is to use CPU affinity to confine all non-BOINC tasks to a single core so that the BOINC work's cache is undisturbed. You will get less BOINC work done on that core and everything else will also run more slowly, but all the other cores will be fully busy with BOINC work. But O/S tasks are so limited in their CPU requirements compared to LLR that their CPU utilization is very low. The gains for BOINC are really by confining threads that consume CPU without doing much, like running javascript in a web browser (if your system is not dedicated to BOINC work).
That's an interesting strategy, never thought about it. Is there special software to do that? Or do you have to do the assigning manually?

My mistake. Sorry. I often get the two confused.

I don't suppose there would be any way possible to get the short "proof" tasks to run on hyperthreads would there?

Or to only get the "proof" tasks? I've still got to read the thread about LLR2 to learn more about it.


1.BOINC automatically uses all the threads available, which includes hyperthreads.
2.Alas, that's not possible. I'd really like another subproject with all the proof tasks but I don't think it'd be realistic. Probs I'd be the only one crunching them. ;)


The problem with having such an option is that the double-check tasks are much shorter than the first-run tasks. What this means is that you'll end up having no tasks to run most of the time - your computer will just be sitting idle waiting for someone to complete a first-run task.

This would especially be the case if too many people decide to switch to the "double-check only" mode; if everyone switches to double checks only, who's doing the first-run tasks? There won't be any results to double-check!

There's no loss of efficiency, actually the opposite, if you take efficiency to mean utilization of hardware. If you mean getting a task done in the least possible time, there are other factors to consider such as cache collisions.
There's no doubt that running 2 threads on one core with HT is slower than running 2 threads on 2 real cores, but it's faster than running 2 threads on one core without HT. A core processes only one thread at a time even with HT - HT just makes switching between threads very fast because the O/S doesn't have to save and restore registers in memory.

The advantage of running 4 threads on 2 cores is that HT gives you the performance of roughly 3 cores. This means the same amount of work gets done sooner.

There's no point to designing a CPU with 3 HT threads per core because 2 HT threads soaks up essentially all the idle core time.

Guys, having a DC only project would be a TERRIBLE idea. It's like having a car that drives perfectly at 50 MPH. But if you increase your speed to 51 MPH, all four tires explode, and if your speed drops to 49 MPH, the engine stalls.

(Yes, we considered this option.)

If there's too many people on the DC project, which I think is likely, everyone on the DC project runs out of work. Yes, you can choose to also run a regular project, but then you're essentially doing the same thing you're doing today -- you'll be getting mostly long tests, and very few short tasks. So why bother?

If there's not enough people on the DC project, everyone's tasks on all the real projects take a long, long time to validate because the DC queue will keep building and building and getting longer and longer. Run like this long enough, and the time you wait to get tasks validated will be measured in years.

The only way you don't have major problems is if the demand for short tasks exactly matched the supply. I'm 100% sure that's not going to happen because if supply matched demand, we wouldn't be having this conversation!

It works much better with the DC tasks being part of the same project as the main tasks. :)

Bottom line is you can not opt-in for just DC tasks, and likely never will.

Another consideration is that a DC task uses the same FFT size as the main task. It means that a DC subproject with tasks from all other projects will have wild swings in FFT size, from 192k to 3072k. This will make computing them efficiently hard.

The advantage of running 4 threads on 2 cores is that HT gives you the performance of roughly 3 cores. This means the same amount of work gets done sooner.

For Intel this is only true on newer machines than at least Core-i 4th gen.
On older ones using two hyper-threads per core slows down llr tasks.
Well, that's my experience.
Don't know about pre-ZEN Ryzen processors, but with ZEN it's full power on all threads as well.

As someone who still runs oldish hardware besides newer machines I consider this as quite important. ;-)

Configuring all that with app_config and PrimeGrid preferences is a little bit annoying, but we want the best experience for all machines, don't we?

What is bunkering? To keep first as high as possible I'm setup to only download one task at at ime.


Its like blood doping. People load up on work units then withhold sending them back until the race starts. Then they upload the work and get a boost to the team score.

It's within the rules so people do it. It can get quite complex for the diehards.

You see that especially on projects that aren't time-critical.
Well, for the most part that includes about every project apart from some PrimeGrid subprojects (think I don't need to elaborate on that ;-) ) and in a way GPUGrid, als you get a bonus for fast turnaround.

The advantage of running 4 threads on 2 cores is that HT gives you the performance of roughly 3 cores. This means the same amount of work gets done sooner.

For Intel this is only true on newer machines than at least Core-i 4th gen.
On older ones using two hyper-threads per core slows down llr tasks.
Well, that's my experience.
Don't know about pre-ZEN Ryzen processors, but with ZEN it's full power on all threads as well.

As someone who still runs oldish hardware besides newer machines I consider this as quite important. ;-)

Configuring all that with app_config and PrimeGrid preferences is a little bit annoying, but we want the best experience for all machines, don't we?

HT performance is highly dependent on the specific workload as well as the CPU model. I've considered the idea of having a pair of hyperthreads cooperate to get one task done faster: one thread does all the computational work and the other fetches data from memory into cache just before it will be needed (so the latter thread spends most of its time waiting for cache lines to be loaded from RAM). One way to keep the worker thread operating solely within L1 cache is to keep the amount of memory it uses small, while the other thread has the job of copying data to and from the worker thread's memory buffers. This scheme will work only if the buffer locations can be used many times repeatedly before needing different data, the concept being that useful work is getting done instead of waiting for data to move through the cache hierarchy.

What is bunkering? To keep first as high as possible I'm setup to only download one task at at ime.


Its like blood doping. People load up on work units then withhold sending them back until the race starts. Then they upload the work and get a boost to the team score.

It's within the rules so people do it. It can get quite complex for the diehards.

and ultimately completely pointless. It's not as though other teams are suddenly going to spin up 1000 servers to compete.

And what's the use? It's not like I'll stop crunching for the challenge just because some guy has lower score.

It might impact people who rent servers. They MIGHT cancel the severs before the end of the challenge because they think they are safely on #1. But does that ever really happen?

To me it sounds like trying to use complicated strategies in a simple game. Basically it's: use all available ressources to crunch the challenge subproject. I doubt any strategy has any significant influence. But I'd love to be convinced otherwise.


Regarding HT'ing on Intel CPUs. In the wake of LLR2, now that throughput is generally more important than fast returns, I tried running 4 WOO tasks on an i7-4750k - the thruput (love that spelling) was smaller. I imagine doing HT will slow things down even more.

How reliable is using Prime95's benchmark?

That is only in best case scenario which are extremely rare. I think I've only seen it in two cases, and old distributed computing project called Life Mapper, and the AMD Ryzen benchmark for Blender using the version of software available at the time, which I understood was not AVX optimised so pretty inefficient anyway. Repeating that with a current version would likely give very different results.

A more well known example of HT/SMT friendly software would be Cinebench R15 or R20. In both cases the benefit from HT or SMT is around 30%. So your 2 cores is more like 2.6 cores. A nice benefit, but not that great. And this remains a better than most example. I think the CPU sieves here also saw nice improvements but I don't recall the scaling factor.

I don't know what the average improvement would be if you took a very wide selection of software, but I'd expect it to be much lower.

In fact it is really annoying to get Ninja'd when you have outlaid hundreds or maybe thousands of dollars on renting hardware for a challenge. Personally, I closely watch the stats and if necessary rent more crunchers from AWS or TSC. Actually, within a challenge, I wish the stats were updated hourly but that would add to the load on PrimeGrid's and bok's Free-DC servers.

Actually bunkering is downloading a massive amount of WU's as the project begins and then holding onto the completed tasks to make a massive dump of WU's and move up the ranks all at once.

Only WU's downloaded after the Challenge begins are tallied. So saving up results prior to the start won't help anyone.

Don't intentionally delay returning results back to the server. When the tasks complete, let BOINC return them to the server. That's all there is to it. Your cache settings (as described in Nick's post) don't matter.

Message 144202 - Posted: 15 Oct 2020 | 4:27:13 UTC

Hello, I've been away from PrimeGrid for a bit due to only having a laptop available for some time. I recently acquired a Ryzen 3600XT, and I'm a little confused about the new multithreading settings.

Prime95 64-bit version 30.3, RdtscTiming=1
Timings for 384K all-complex FFT length (6 cores, 1 worker): 0.28 ms. Throughput: 3520.39 iter/sec.
Timings for 384K all-complex FFT length (6 cores, 2 workers): 0.41, 0.40 ms. Throughput: 4947.41 iter/sec.
Timings for 384K all-complex FFT length (6 cores, 3 workers): 0.64, 0.73, 0.60 ms. Throughput: 4630.21 iter/sec.
Timings for 384K all-complex FFT length (6 cores, 6 workers): 1.12, 1.14, 1.13, 1.14, 1.16, 1.13 ms. Throughput: 5287.88 iter/sec.
Timings for 384K all-complex FFT length (6 cores hyperthreaded, 1 worker): 0.30 ms. Throughput: 3300.74 iter/sec.
Timings for 384K all-complex FFT length (6 cores hyperthreaded, 2 workers): 0.37, 0.37 ms. Throughput: 5384.34 iter/sec.
Timings for 384K all-complex FFT length (6 cores hyperthreaded, 3 workers): 0.53, 0.60, 0.54 ms. Throughput: 5370.18 iter/sec.
Timings for 384K all-complex FFT length (6 cores hyperthreaded, 6 workers): 1.03, 1.03, 1.05, 1.03, 1.04, 1.04 ms. Throughput: 5784.13 iter/sec.

It says in this thread's first post that multithreading is recommended, yet I still seem to get better results running one task per core. Is this because of the large cache size of the new processors?

The result for the 6 cores, 3 workers test looks a little strange. Is this because of cache boundaries or something similar?

Also, I'm a bit puzzled by the apparent increase in performance when hyperthreading is used. Last time I checked, hyperthreading was always supposed to be disabled for LLR, but now I seem to get a ~10% performance increase with hyperthreading enabled, at least with the Prime95 benchmark. This also comes with a ~15% power consumption increase, however, and this processor already runs hot, even with a good cooler.

Are these results normal, specific to the new Ryzens, or is there something unusual with my setup?

I have also seen that in this subproject, throughput is highest without multithreading, i.e. each worker uses just one thread. Before LLR2 with Pietrzak certificates (or what we call them), many people multithreaded despite lower throughput because of the desire to be 1st. This is irrelevant now.

I do not know about hyperthreading and the other things you ask.

With Ryzen it's fastest to run 1 task per core for this project.
What I believe the prime95 results mean is that it's also best to leave hyperthreading switched on with processor usage set at 50%.
People have also found it's faster to set the affinity for each task to a core: in this case a pair of processors: 0+1, 2+3 etc.

Multithreading is required for better usage of internal CPU cache. If your CPU have lot of cache and task FFT size is small (i.e. everything can fit inside cache without significant conflicts), running one task per core will be more efficient.

Note that it seems that during challenge we will start sending 400K and 480K-FFT tasks.

It says in this thread's first post that multithreading is recommended, yet I still seem to get better results running one task per core. Is this because of the large cache size of the new processors?

Zen 2 (and soon Zen 3) have a relatively large amount of cache per core, so some types of tasks may fit in that running one per core.

The result for the 6 cores, 3 workers test looks a little strange. Is this because of cache boundaries or something similar?

Yes, you have a 6 core CPU that's organised as 2x 3 core groups. When running 3x 2 core tasks, one of the tasks crosses the group boundary and can result in reduced performance.

Also, I'm a bit puzzled by the apparent increase in performance when hyperthreading is used. Last time I checked, hyperthreading was always supposed to be disabled for LLR, but now I seem to get a ~10% performance increase with hyperthreading enabled, at least with the Prime95 benchmark. This also comes with a ~15% power consumption increase, however, and this processor already runs hot, even with a good cooler.

I have not seen that on Ryzen myself, but in much earlier testing I found using hyper-threading on Intel can undo lost performance if something else is causing a reduction in performance.

There is a new consideration with Zen 2 CPUs, in that Windows doesn't work optimally at spreading the load and using other tools to keep tasks on a core group can increase performance. I wonder if this might be related.

It might impact people who rent servers. They MIGHT cancel the severs before the end of the challenge because they think they are safely on #1. But does that ever really happen?

In fact it is really annoying to get Ninja'd when you have outlaid hundreds or maybe thousands of dollars on renting hardware for a challenge. Personally, I closely watch the stats and if necessary rent more crunchers from AWS or TSC. Actually, within a challenge, I wish the stats were updated hourly but that would add to the load on PrimeGrid's and bok's Free-DC servers.


And its the renting of servers which is why I don't try to beat your stats in any projects Vaughan. I buy & own all my hardware so can't compete on the same level.

It's one of my few dislikes about the generic stats. It doesn't compare apples to apples (Account managers like Gridcoin, universities/business or those who rent crunching pc's vs the guy sitting at home.)
That's just the way it is, I've accepted that..... but it's eroded my competitiveness with regards to BOINC projects, challenges & stats.

Goodluck to all in the challenge. I hope someone finds a prime # :)

We'd need to advance about 40,000 digits to 1,998,833. That's an increase in n of about 135,000, so due to sieving maybe 4000-5000 WUs?

But it's 23 k's, so in total 120,000 WUs. According to stats PPS-DIV currently does 6000 tasks a day, so it would be 3 weeks at that pace. Seems definitely doable during the challenge, rank 98 is pretty close as well with 2,005,115 digits.


And I'll probably manage SGS amethyst just before the challenge, so I'm good to go!!! ;)

It appears that mighty firepower from my Xeon is not able to participate :(

Anyone care to tell me what the error "-226 (0xFFFFFF1E) ERR_TOO_MANY_EXITS" mean and what can be done to rectify it?

The host in question is this one: https://www.primegrid.com/results.php?hostid=946415

Thank you.

PS. Must add, there was some sort of a Win10 update about 2 days ago wich has also crashed the sound, so may it have something to do with that update? I'm having a Win7 computer it runs without incidents.

Looks like the error message is "too many exit(0)s". The program terminated with no error flag, more than once, without completing.

Have you tried resetting the project in BOINC Manager?

Already at 1970000 digits, so only 30,000 digits or 100,000 n to go. Apparently people were preparing for the challenge? Rank of 100+ is almost certain during challenge. Although T5K is so dominated by PG, that each prime we enter is likely to kick another one off... ;)

No, that I haven't tried. Very good suggestion. I think I'll try that and clear the slots, since 2 of the 6 very still holding files despite I aborted and I also had to LLR2 instances running in the RAM, despite the tasks being killed in BOINC. Very weird.

Now another question, the Xeon has 30MB of cache, am I correct that it is too many task to fit in the cache if I run 12 task, but memory being big enough to fit 6 task running on 2 cores?

Tasks are currently using 384k FFT, which should use about 3MB cache. They will likely go up to 400K and maybe some 480k FFT sizes, which wouble be a bit over 3.2MB and 3.8MB, respectively.

So yes, 12 tasks would overrun the cache size. 6 tasks should fit in the 30MB cache even at the larger FFT size with room to spare.

Since many people discuss FFT size and cache and how many threads were optimal:

it seems like just using the Prim95 benchmark isn't sufficient? Do the results deviate from real world applications?

As far as we can tell, you're the only person with this problem. However, this is not a problem that leaves a clear record on the server. We only know about it when someone complains. None of us are having this problem. Is this happening on more than one computer, or are you aware of it happening to anyone else?

EDIT: Also, are all of the upload files blocked, or just some of them?

EDIT2: Right now, we think it's a network problem on your side. Possibly a router with an incorrectly configured MTU, or blocked lost ICMP. If you're only crunching at PrimeGrid for the challenges, you would not have seen this before because this is the first challenge using LLR2, which uses sends much larger files back to the server.

Thanks for your reply,

this problem only occurs on Primegrid, all other projects work without any issues.
most of the files upload directly, but about 1/4 of the uploads get stuck, resulting on wus, which won't report -> no new wus, because to many wus uploading.
i just started primegrid again after a few months, first time with LLR2.
321sv works fine too.
i never had this issue before on primegrid. This problem occured once at climateprediction.net, because the server couldnt handle the amount of uploads.

Networking should be stable, never had any issues here.

I actually was thinking about asking if you had trouble with CPDN, because they're one of the few projects that has large uploads.

Unfortunately, we've been running LLR2 for a few months now and you're the only person that has reported upload problems, *and* you also have had problems uploading large files elsewhere. That points towards a problem on your side (or in the network somewhere close to you.)

I did notice that eventually the task you mentioned did get the files uploaded.

Message 144427 - Posted: 19 Oct 2020 | 22:23:00 UTC - in response to Message 144404.

it seems like just using the Prim95 benchmark isn't sufficient? Do the results deviate from real world applications?

It is a starting point, and there can be differences.

For example, I just did a fresh install on a 3700X system. I know it should be best with 1 task per core (although I have seen elsewhere that using SMT might improve it further, I haven't tested this). When I set it up with 1 task per core, I saw Windows being stupid, putting two tasks on the 1st core, with the last core idle. I had to manually set affinity to correct this.

From experience, Windows needs a nudge at times when running 1 thread per task on HT/SMT enabled CPUs. Something changes when running more than one thread per task and that requires less manual intervention.

Felix,

I have good news, and bad news.

The good news is I found a second person with the same problem. One of our admins, in fact.

So it's not you.

The bad news is he's also in Germany.

The really bad news is he's on the same ISP as you.

The problem appears to be your ISP, or at least it's somewhere in their network.

Hello!
Something weird with the current challenge stats!
If You look at the top 16 , they have gotten some real
big ones giving more than 100 000 in credit!

Guess the stats is not complete cleaned after the previous challenge?

Good luck everyone with the challenge!😷

Stats are currently broken, a fix is on the way. Please wait for few hours until it's done.

This is our first LLR2 challenge and a bug in new code slips somehow through testing.

I've got machines running way too hot! Even at just 50% I'm still registering temperatures in the "critical" range.

Felix,

I have good news, and bad news.

The good news is I found a second person with the same problem. One of our admins, in fact.

So it's not you.

The bad news is he's also in Germany.

The really bad news is he's on the same ISP as you.

The problem appears to be your ISP, or at least it's somewhere in their network.


No such problem here in Saarbrücken (Germany). ISP is Telekom Deutschland.

It'll be much better. Since all tasks are already returned and passed preliminary phase of validation, all what should be done is to wait for return of their corresponding certificate tasks. As usual, there can be hosts which times out, and we must wait for them. But deadline of certificates is fixed to 3 days. It means - LLR2 cleanup time will not depend on project. It's be same for DIV and SOB.

Second, Final score will not change significantly. Tasks which passed preliminary phase but failed certification do exist (user's hardware was extreme faulty), but it was less then 10 tasks for all period of existence of LLR2 on PG.
