Welcome to the Double Top Secret Mystery Challenge

What's up with the name? Well... I could tell you, but then I would have to kill you seeing how it is a riddle, wrapped in a mystery, inside an enigma.


An 15 day Challenge is being offered on PrimeGrid's Prime Sierpinski Problem (LLR) application. To participate in the Challenge, please select only the Prime Sierpinski Problem (LLR) project in your PrimeGrid preferences section. The challenge will begin 1 March 2014 18:00 UTC and end 16 March 2014 18:00 UTC.

NOTE: In your PrimeGrid preferences section, set "Send work from any subproject if selected projects have no work" to no to guarantee that no other work will be sent.


Back in 2010, when we had the last challenge on PSP, John posted this:

This is the 2nd Challenge for PSP LLR and will be by far, the most demanding Challenge yet.


Although a 15 day challenge with units taking 114 hours on the average system is still quite the challenge to be had, we have faced far more taxing challenges like the Genefer short and world record this year.

How to participate:
In order to participate select (only) the Prime Sierpinski Project in your preferences

NOTE: In your PrimeGrid preferences section, set "Send work from any subproject if selected projects have no work" to no to guarantee that no other work will be sent.

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 45-55 hours on fast/newer computers and 110+ 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. :)

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 1 March 2014 18:00 UTC and received BEFORE 16 March 2014 18:00 UTC will be considered for credit. [color=red]We will use the "prime score" method
which is based on the n value (k*b^n+1) to score the challenge. The only difference is that the primary and double checker of a WU will receive the same score.

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 kindly ask users "moving on" to ABORT their 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. :)


About the Prime Sierpinski Problem

Waclaw Franciszek Sierpinski (14 March 1882 - 21 October 1969), a Polish mathematician, was known for outstanding contributions to set theory, number theory, theory of functions and topology. It is in number theory where we find the Sierpinski problem.

Basically, the Sierpinski problem is "What is the smallest Sierpinski number" and the prime Sierpinski problem is "What is the smallest 'prime' Sierpinski number?"

First we look at Proth numbers (named after the French mathematician François Proth). A Proth number is a number of the form k*2^n+1 where k is odd, n is a positive integer, and 2^n>k.

A Sierpinski number is an odd k such that the Proth number k*2^n+1 is not prime for all n. For example, 3 is not a Sierpinski number because n=2 produces a prime number (3*2^2+1=13). In 1962, John Selfridge proved that 78,557 is a Sierpinski number...meaning he showed that for all n, 78557*2^n+1 was not prime.

Most number theorists believe that 78,557 is the smallest Sierpinski number, but it hasn't yet been proven. In order to prove it, it has to be shown that every single k less than 78,557 is not a Sierpinski number, and to do that, some n must be found that makes k*2^n+1 prime.

The smallest proven 'prime' Sierpinski number is 271,129. In order to prove it, it has to be shown that every single 'prime' k less than 271,129 is not a Sierpinski number, and to do that, some n must be found that makes k*2^n+1 prime.

Seventeen or Bust is working on the Sierpinski problem and the Prime Sierpinski Project is working on the 'prime' Sierpinski problem. The following k's remain for each project:

Sierpinski problem 'prime' Sierpinski problem 10223 10223* 21181 22699* 22699 67607* 24737 79309 55459 79817 67607 152267 156511 168451 222113 225931 237019 '*being tested by Seventeen or Bust

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 Penné 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:

For LLR, HT "off" is generally preferred. "Your mileage may vary".

Go Aggie.

Is it worthwhile to run with HT Off ?

Thank You


Yes.

General rule of thumb is it's better to run LLR with HT off. During challenges, this is especially true.

If you have a CPU with AVX, it's even more important to run with HT off.

There's no benefit to using HT with LLR, so, at best, with HT on everything runs at half the speed as you crunch twice as many tasks. That's not good during a challenge because you want tasks to complete as qucikly as possible. Completing X tasks AFTER the deadline is worse than completing X/2 tasks BEFORE the deadline.

But "at best" does not describe this situation. Since LLR, especially with AVX, suffers from memory contention problems, 8 LLR tasks don't run at half the speed as 4 LLR taskz -- they run slower than half speed. Overall, your total throughput will be less with HT on.

And, finally, since with LLR you're looking for prime numbers, if you have two identical computers start crunching the same number at the same time, except one has HT on and the other has HT off, the computer that has HT on will finish that task much later and the other guy will get credit for finding the prime.

For all those reasons, HT should be off. The only time you'd want HT on is if you're running TRP-Sieve or PPS-Sieve (on the CPU), where there's an advantage to using hyperthreading. Even then, during a challenge it might not be worth it.

I am a bit confused. The announcement talks about the end of a hiatus for PSP., but doesn't specify LLR or sieve. This thread says it is the LLR version of PSP. But the hiatus has been for the sieve version of PSP, not LLR. Is there going to be work available for sieve? That is the badge I need to work on.

Hiatus from being used in a challenge.

It is the LLR.

The "hiatus" that was referred to is the long time since the last PSP-LLR challenge.

This is a PSP-LLR challenge. There is no plan to restart PSP-Sieving any time in the near future.

(Well, almost. If we move ESP from PRPNet to BOINC, we'll probably need to do more sieving for ESP. Since SoB, PSP, and ESP are all part of the same big conjecture family, the sieving is the same for all of them. If we have to do sieving for ESP we might do it under the PSP BOINC project rather than set up another BOINC app. At this time, that's the most likely scenario for restarting the PSP Sieve.)

I think you get better performance if you actually turn HT off in the BIOS rather than just tell BOINC to use 50% of the cores. This will force LLR to run on separate cores, otherwise I think you could have multiple instances of LLR on the same core and a core not doing anything.

It's much better to turn it off in the BIOS. If your BIOS allows you to do that, of course. Not all do.

If you can't turn off HT, then yes, set BOINC to run on 50% of the threads.

Will be there too, I hope ;)

Is it worthwhile to run with HT Off ?

Thank You

HT..what`s this? ….Hyper Threading?


Yes.

So we should set 50% of CPU usage right?


It's much better to turn it off in the BIOS. If your BIOS allows you to do that, of course. Not all do.

If you can't turn off HT, then yes, set BOINC to run on 50% of the threads.

Or use software such as ProLasso to set the affinity to all even or odd CPU cores for better core distribution so that HT is minimally used.

For Mac LLR crunchers - I've tried several things to disable hyper-threading on my Mac Pro and finally in this thread found the winner:

From inside the terminal app, run:

sudo nvram SMT=0


It has survived reboots and one system update. Happy crunching!

If you have a 4 cores PC, (8 virtual core) ( or what you have ) they put in the settings to 39%. 1 core you need for the> graphics card

It run 3 cores

If the graphics card is not running (Genefer or PPS sieve), then they can also run 4 cores, so 50%

Some people do not know that.

How to do this Settings ?

Open BoinC Manager


Advanced-->Preferences-->processor usage-->on multiprocessors, use at most 50% ( or 39% )

Its better I write it again, before the challenge starts. So we have all a better result.

The best is, "It's much better" to turn it "off" in the BIOS. If your BIOS allows you to do that. ( what Mike`ve wrote :) this is better fpr "ALL" LLr`s

You do not have to reserve a core for the GPU. The GPU needs very little CPU, and it's entirely possible to run all the cores on LLR and also run a task on the GPU.

As with all other "tuning" advice, actual results results will vary from system to system and you should try it on your specific hardware. I personally have never seen a significant speed increase in the GPU app by leaving a core free for it.

A small increase, yes, so if I'm participating in a GPU challenge I might leave a core free to try to squeak in one more task. Likewise, if participating in a CPU challenge I'd leave the GPU turned off hoping to squeak in on more CPU task. But normally, I'd run everything.

But "your mileage may vary", as they say, so try it both ways to see what the real results are on your hardware.

(You should ignore what appears to be 100% CPU usage by OpenCL GPU apps. It's a byproduct of the way the driver works and the app is NOT really using 100% of one core, despite what the system utilities are telling you.)

My experience

If you're running Gfn WR, save with the disconnected core in the bios 48mins or 1 hours. For PPS sieve do not notice them

As long as no challenge standings are final, there are no overall standings. I would guestimate that the first update to the overall standings will become available near the end of April.

You have to wait until there are some standings to be included in the overall standings. That's probably another 6 weeks or so.

There are no overall standings yet because there are no individual challenges that are completed. The January challenges and the March challenge are both for very long tasks with long deadlines and hence very long cleanup times of about three months. I expect the January challenges to finish the cleanup phase sometime in April, and the March challenge to finish its cleanup sometime in June. It's possible that the April challenge, for PPS-LLR with a 3 day deadline, could be the first challenge to have official results.

How long we have to wait for the Current Overall Standings?


You have to wait until there are some standings to be included in the overall standings. That's probably another 6 weeks or so.

There are no overall standings yet because there are no individual challenges that are completed. The January challenges and the March challenge are both for very long tasks with long deadlines and hence very long cleanup times of about three months. I expect the January challenges to finish the cleanup phase sometime in April, and the March challenge to finish its cleanup sometime in June. It's possible that the April challenge, for PPS-LLR with a 3 day deadline, could be the first challenge to have official results.

Thank you :-)

Is it worthwhile to run with HT Off ?

Thank You

HT..what`s this? ….Hyper Threading?


Yes.

So we should set 50% of CPU usage right?


It's much better to turn it off in the BIOS. If your BIOS allows you to do that, of course. Not all do.

If you can't turn off HT, then yes, set BOINC to run on 50% of the threads.


Could you please elaborate on how this is beneficial?

I have 4 physical cores, which gives me 8 threads. When running 100% CPU usage, all tasks get about 11-12% of the cpu.
Running at 50% gives me 4 threads, each using 17.1 - 17.3% of CPU.

I can not understand how HT is a bad thing in this case. More of the CPU is active, and more tasks are being completed in a close to equal time span.

Let's say an arbitrary LLR task takes 2 hours to run without hyperthreading. LLR is the kind of task where hyperthreading doesn't help at all. If you turn on hyperthreading, you'll be running two tasks simultaneously, but each task will take 4 hours to run instead of two. The net throughput is the same: 1 task every two hours. The only difference is you're running two four-hour tasks at once rather than two two-hour tasks sequentially.

So it seems like it doesn't matter and you get the same amount of work done either way, but it's more complicated than that.

Let's say you have 2 hours left to go in the challenge. If you have hyperthreading turned off, you can complete one more task in those two hours. But if you have hyperthreading turned on, at the end of two hours, instead of one completed task (which will count for the challenge) you'll have two tasks which are only half done, and neither will count towards the challenge. By running without hyperthreading, you can potentially get a few more tasks completed during the time frame of the challenge.

Finally, there's the memory contention problem, and this is a big one.

With LLR running with reasonable size numbers (which includes everything done at PrimeGrid), the CPU is somewhat limited by the speed of main memory. The numbers are large enough so that the CPU cache isn't big enough to hold all the data for 4 LLR's running at once, If you run 1 copy of LLR and it takes, say, 1 hour to run, running 2 copies (on two real cores) might take 65 minutes. Running 3 copies might take 75 minutes. Running all 4 cores might take 90 minutes. As you run more and more copies of LLR, they all slow down. If you use hyperthreading and run eight copies, it gets even worse. Because of the memory contention, the LLR taskls run faster when you're running fewer instances of LLR, so the last thing you want to do is double the number of tasks and cause even more memory contention.

My example of the top was simplified. In reality, if you run without hyperthreading on your 4 cores and can run 4 tasks in 2 hours, what will happen if you turn on hyperthreading is that your 8 tasks don't complete in 4 hours. Your 8 tasks will likely complete in 5 hours. By turning on hyperthreading, you're dropping your throughput from 2 tasks per hour to 1.6 tasks per hour.

It's not how "busy" the CPU is. That measurement has its limitations and in this situation isn't giving you useful information. It's how much work is being done, and you'll get a lot more crunching done running with hyperthreading disabled.

The 2 benefits of running LLR with Hyperthreading off,

1. Speed - Tasks complete faster

2. Heat - CPU runs cooler (air-cooled 3770k)

I'm guessing the first results will start showing up around 31 hours into the challenge (3-Mar 01:00 UTC).

(31 hours was my guestimate based on how fast my PC is running vs. what a heavily overclocked Haswell or IV-E i7 aught to be able to do. The database shows the fastest valid PSP task taking 31.5 hours.)

One day into the challenge and there are 6370 tasks being worked on. I believe about 7000 tasks total were crunched the last time we ran a PSP challenge several years ago. Not all of those will complete successfully, or complete during the challenge, but that's still an impressive number of tasks out in the field!

Although the tasks are longer now than they were back then, our computers are a lot more powerful with AVX and more cores. The fastest computers can crank out 1 PSP task per core in less than a day and a half. The first results should be coming back about 7 or 8 hours from now.

Curious about what people are running that's REALLY fast? So was I. Here's the fastest PSP results along with the CPU. Note that in the few cases where 8 cores are shown (i.e., hyperthreading is turned on), either BOINC was being run on no more than 50% of the CPUs, or hyperthreading was turned off at the time the PSP was crunched.

Here's the 50 fastest validated PSP tasks currently in the database:

One day into the challenge and there are 6370 tasks being worked on. I believe about 7000 tasks total were crunched the last time we ran a PSP challenge several years ago. Not all of those will complete successfully, or complete during the challenge, but that's still an impressive number of tasks out in the field!

Although the tasks are longer now than they were back then, our computers are a lot more powerful with AVX and more cores. The fastest computers can crank out 1 PSP task per core in less than a day and a half. The first results should be coming back about 7 or 8 hours from now.

So good ! Keep crunching PSP ! :)

Michael, looking at your 50 fastest chart, it appears that the data being pulled is what Windows would report as the CPU speed (at default) and not the overclocked speed. It would be interesting to know what actual speeds all those CPUs are running to get a feel for what it really takes to be in the "fastest 50".

I believe that's what the CPU itself is reporting -- its processor string reflects the factory speed, not the actual speed.

There's no way for a BOINC server to obtain the actual speed from the BOINC client, and I'm not even sure the BOINC client can obtain that information. Regardless of whether it can obtain that information, it certainly doesn't at the present time.

I too would be very interested in that information. :)

That's about 29 hours, which is a good 2 hours faster than anything in the database. What are you running, and at what speed?

My first results should be coming back in about 1 hour from now… :-)


That's about 29 hours, which is a good 2 hours faster than anything in the database. What are you running, and at what speed?

He apparently was only running one core. One copy of LLR will run significantly faster than 3 or 4 copies. The difference between running 1 instance and 4 instances can be as much as a 25% change in speed.

AVX2 (Haswell) doesn't help LLR.

The reason 4930 doesn't have AVX2.0 is because of Intel's marketing department. Not sure it is really newer (EDIT:- Ok, it did come out later than 4770K)

Have a look at http://ark.intel.com/products/family/79318/Intel-High-End-Desktop-Processors/desktop and
http://ark.intel.com/compare/77779,77780,77781,70845,63696,63697,63698. You can see that 4930 is in fact 3rd gen Ivy Bridge-E processor, not a Haswell.

We're about 41 hours into the challenge and results are starting to come back in. We're at the point where non-overclocked (or lightly overclocked) Core i5s and Core i7s with AVX could have completed a set of 4 tasks, so I expect lots more to be coming in within the next day. At this time, 66 results have come back, and all but two are from unlocked ("K") series Core i7s. There's one Core i7-3770 that's presumably not overclocked that's returned two results.

Good luck and happy crunching.

Yes, I have lost my mind, so we need a slogan.

"May the primes be with you!"

"Use the over-clock, Luke!"

"May the primes be ever in your favor." (This is a prime finding contest to the death?)

I'm seeing something interesting in the results that are coming in. This may be of interest to anyone planning to build a new computer.

At this point, the list is completely dominated by Sandy Bridge, Ivy Bridge, and Haswell K series Core i7s. That's hardly surprising. There's one not-unlocked (non-K) i7 in there, one Sandy Bridge Xeon, and my i5.

What's surprising is that I sorted the list by CPU time, and my i5 comes out fairly close to the top. It's not just faster than 4770K i7s; it's faster than some quad-channel IV-E Core i7 Extreme CPUs too.

The i5 is not that fast and I certainly don't have it overclocked until it's glowing. The i7's with their larger L3 cache are faster, and the quad channel -E CPUs have a huge advantage. It's the 2400 MHz memory that's making the difference.

What's important here is that 2400 MHz memory is no longer exotic and expensive. I was able to buy 8 GB (2x4GB) for about $80 or $90, and it was essentially the same price as the equivalent 1600 MHz parts.

So if you're looking to build new (or looking to boost the performance of your current system and your motherboard supports it), putting in 2400 MHz memory might be the way to go.

EDIT: Adding some numbers:

I had run a set of 4 PSP's last week with the memory set at 1600 MHz, and I just completed 4 more for the challenge today. The PSPs that finished today were about 10% larger than the ones last week, but they finished about 17% sooner. The computer is therefore about 25 to 30 percent faster with the memory set to 2400 MHz. (It's possible that 6% of that might be due to the CPU being slightly overclocked. The CPU appears to be running at a higher clock rate, but I didn't explicitly overclock it. I'm not sure if the BIOS did that on its own or if the instrumentation is misleading.)

Temperatures are at most 2 or 3 degrees higher. That's excellent for a 25 to 20 percent speed increase!

What's surprising is that I sorted the list by CPU time, and my i5 comes out fairly close to the top. It's not just faster than 4770K i7s; it's faster than some quad-channel IV-E Core i7 Extreme CPUs too.

The i5 is not that fast and I certainly don't have it overclocked until it's glowing. The i7's with their larger L3 cache are faster, and the quad channel -E CPUs have a huge advantage. It's the 2400 MHz memory that's making the difference.

What's important here is that 2400 MHz memory is no longer exotic and expensive. I was able to buy 8 GB (2x4GB) for about $80 or $90, and it was essentially the same price as the equivalent 1600 MHz parts.

So if you're looking to build new (or looking to boost the performance of your current system and your motherboard supports it), putting in 2400 MHz memory might be the way to go.


Good stuff there! However it will have to wait until the next build. :D

I think that I'm seeing something "interesting" as well. That is, "don't bring Servers to a PC fight". A lot of Server processors can dump a bunch of WUs, but may only get one shot at it over a 15 day period (due to very long run-times). Looking at the various rigs of those that are already posting numbers, I too see a pattern. Lots of 4-processor rigs! From what has been shared here about the LLR WUs, I believe there is a "best strategy" and unfortunately in my case, I brought the wrong hardware. :)

It depends on how many server chips you bring to the fight. The people who are likely to end up on top of the charts will do so with tens or hundreds of cores, although they won't necessarily be very fast. (If Randy were participating, it would likely be thousands.)

The server chips (at least some of them) have triple or quad channel memory buses, which are a big advantage with LLR. The BIG server chips with lots of cores and support for multiple CPU chips on the same motherboard usually A) don't have AVX, B) run at lower clock speeds, and C) may suffer from more memory contention. So the tasks will take longer, but you will be doing a whole lot of tasks at once.

There's a few hex-core machines (with either 6 or 12 threads) that have already turned in tasks, although it's almost certain they're running no more than 6 tasks at once.

For challenges, especially for long tasks, crunching fewer tasks faster is always better than crunching more tasks slowly. You may get stuck in the situation where you have time to finish 1.99 tasks per core. :(

Michael, by my own calculations (not BOINC's estimator), my 4P AMD 6180 Server (48 CPUs total) at 2.5Ghz is going to take so long that I'll likely only complete (1) stint of work in the 15 day period. My calculations currently indicate that it will finish that 1st stint on 3/10 and then can't do another before the contest ends. So, it is a one-shot 48 WU performance. The length of the WUs (as you and others have pointed out) are better suited for processors with less cores. Now if I had a Server Farm of 100 Servers, yes that would be fun to watch when that total pile hit the fan! :)

If you finish 48 during the challenge, you'll still beat someone with a 4-core machine that only takes a day and a half per WU. So don't despair! :-) Of course the downside is that during the last few days of the challenge, you'll have to sit there and watch quietly as people with *multiple* really fast machines move ahead.
Cheers,

Gary, I'm not despairing at all. :) Just facing a dose of reality because of how these WUs play with differing CPU counts. Of course, there is no comparison between a 48-core Server and a single 4-core machine. But, to highlight what we are all knowing, on the other hand, (4) 2600K (or better) PCs @4Ghz, with a total of 16 Cores, at 72hrs to haul-in (4) WUs each will best that 48-core Server with almost double the production by the contest end. So, as you said, multiple 4-core rigs is where it is at (the sweet spot)! All in good fun though and hopefully useful somewhere! :)

Unfortunately, server or not, AMD CPUs these days are always at a severe disadvantage when running LLR or Genefer because of the lack of a decent AVX implementation. At least in terms of raw speed. An argument might be made that AMD is competitive in the credits/dollar equation, but in terms of raw speed AVX is just too much of an advantage.

It gets rather more complicated when you figure in space and power requirements and the use of GPUs as well as CPUs. Would you have someplace to put those 4 quad-core systems? What's their power consumption compared to your rig?

I find that I'm better served with dual-socket workstations than single-socket systems. I can run 3 dual-socket workstations with good GPUs on a single power circuit without tripping breakers (as long as there's not too much else on that circuit). Maybe I could run 4 single-socket systems with good GPUs, or 3 and a couple with minimal or no GPU, but that would be about it. It's the power circuits that limit what I can run, so if I want to run GPUs the dual-socket systems are better overall. If I wanted to maximize my production in CPU challenges, that might be different.

Ahhhh, yep I forgot about that AVX feature that you guys have been talking about. My 6180SEs don't have AVX...hafta get to the 62xx series for that feature I believe. I'll still finish up the LLR work that I have in queue and then move the server to some other work. Nothing will be wasted for sure.

Tng, space-wise (4) rigs certainly would exceed the footprint of my 4P Server. From a wattage perspective, my 4P (less monitor) is using 760W while crunching 48 threads of LLR. My 2600K @4Ghz by comparison (less monitor) is consuming 243W. So, you would have to exceed (3) 2600Ks to climb over the Watts that my 4P is consuming while crunching.

I wasn't really caring about wattage, foot-prints or any other costs. Just looking at it from a contest production perspective and solely within the results for these LLR WUs.

And your assessment was entirely correct from that viewpoint. I was just voicing some idle thoughts about other viewpoints that your post triggered. Mostly just turning my mind to lighter things after a day at work.

Realistically, I buy most of my hardware either because there's something cool about it, or because it's a bargain.

Interestingly, the box that's the fastest on these tasks was one of the few that I've bought for purely functional purposes. While I looked for something that could do some good crunching, I didn't pay much attention to details. Need to look at that system more closely . . .

Here's at least two big servers that are really rocking it...

| 2014-03-01 18:00:41 | 4712134 | 13,978 | 197,603 | Intel(R) Xeon(R) CPU E5-2697 v2 @ 2.70GHz | 48 | | 2014-03-01 18:00:41 | 4721757 | 14,035 | 198,607 | Intel(R) Xeon(R) CPU E5-2697 v2 @ 2.70GHz | 48 | | 2014-03-01 18:00:42 | 4712520 | 13,292 | 200,516 | Intel(R) Xeon(R) CPU E5-2695 v2 @ 2.40GHz | 48 |


48 cores and they're cranking out tasks in about 200K seconds. Of course, they're likely hyperthreaded with half the threads idle, but that would still be 24 tasks every 55 hours.

The mysterious numbers are the size in digits, the challenge points, and the cpu seconds.

(Someone will probably notice that the third result a has more digits but a lower challenge score than the first result. That's because the third result used a larger FFT size and was actually a larger calculation despite the number having fewer digits.)

Impressive numbers on those E5 Xeons Michael. Wish I had some! Looks like they are finishing in ~55hrs? Now those are Servers that put some hurt on number crunching. I like that and thanks for sharing it.

If you're like me, you've figured out an optimistic estimate of how many tasks you might be able to squeeze in during this challenge.

If you're like me, you might be noticing that it's not working out as planned. Here's why.

Last week I figured I'd prepare for the challenge by running a set of PSP tasks to see how long they take. They took X hours, and 360/X times the number of cores tells you how many tasks you can complete. Very simple.

Too simple, actually.

We're mashing through PSP at a pretty good clip, and the tasks are getting longer rather quickly. I noticed this morning that the in-progress PSP tasks were taking a lot longer than the last set. I wasn't sure if the computer was running more slowly or the tasks were just longer. The tasks ARE longer.

I've run three sets of PSP tasks on this computer so far.

Set number 1, run last week had challenge scores ranging from 12,120 to 12,124 . The challenge score, like credit, is proportional to the amount of time it takes to crunch the task.

Set number 2 (at the start of the challenge) had scores ranging from 13,283 to 13,329.

Set number 3 (running now) ranges from 13,431 (that's a resend) to 14,965.

14965/12120 is an increase of 23% over the course of 1 week. If you downloaded a bunch of tasks at the start, you won't be affected by this, but if you download the tasks only when needed like I do, each new task may be significantly longer than the last one. Predicting how many tasks you'll be able to complete is probably impossible.

(I actually like the uncertainty. Now that I know I can't actually do 36 tasks during the challenge, I'm less stressed about trying to do so.)

Status after a bit less than three days:

642 tasks returned.
9533 are currently in progress.

Michael,

Yes, (hand going up) I have been looking at how many tasks I can do (by rig). I've been doing my own calculations (daily) based upon actual %complete and actual elapsed hours.

But, I'm pretty new to these LLR tasks, so I don't quite get why they would increase in size (~23%). What causes that to happen (if it isn't too technical to describe)?

Good question. One simple answer and one not as simple answer.

The simple answer is that we're essentially crunching numbers in sequential order, and each number is larger than the first. As time goes on, the tasks naturally get longer and longer.

The not so simple answer is that in addition to the numbers getting larger, the internal mechanics of the calculation have thresholds. As you pass each threshold the calculation needs to use a larger FFT (Fast Fourier Transform), and the larger the FFT, the longer each step in the calculation takes. FFT sizes also increase as the size of the number increases, but it's not a linear relationship. Some larger numbers may use a smaller FFT than some smaller numbers do, and therefore some larger numbers take less time to compute than some smaller numbers.

The credit and challenge score formulas take all of this into account.

All of the BOINC tasks grow in this manner except for the sieves (which are always the same size) and SGS. SGS grows, but its growth is so slow you'll never notice it. (That's because with SGS it's k that is increasing while with all the other LLR projects it's n that increases.)

The GFN projects grow, but unlike with LLR, the FFT size doesn't change so the credit/score calculation is somewhat simpler.

Challenge: Double Top Secret Mystery
(As of 2014-03-04 14:50:54 UTC)

17773 tasks have been sent out. [CPU/GPU/anonymous_platform: 17753 (100%) / 0 (0%) / 20 (0%)]

Of those tasks that have been sent out:

7509 (42%) came back with some kind of an error. [7509 (42%) / 0 (0%) / 0 (0%)]
686 (4%) have returned a successful result. [678 (4%) / 0 (0%) / 8 (0%)]
9578 (54%) are still in progress. [9566 (54%) / 0 (0%) / 12 (0%)]

Of the tasks that have been returned successfully:

603 (88%) are pending validation. [597 (87%) / 0 (0%) / 6 (1%)]
75 (11%) have been successfully validated. [73 (11%) / 0 (0%) / 2 (0%)]
0 (0%) were invalid. [0 (0%) / 0 (0%) / 0 (0%)]
8 (1%) are inconclusive. [8 (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=15999653. The leading edge was at n=15683076 at the beginning of the challenge. Since the challenge started, the leading edge has advanced 2.02% as much as it had prior to the challenge!

As with the GFN challenges in January, you'll notice a large number of errors. And, just as with the GFN tasks, those errors represent a small number of hosts that are returning a prodigious number of errors. The number of errors isn't in itself very significant.

I had a Linux install blow up and contributed nine of those errors :/ It's all better now so hopefully my machines will behave from here on out. I'm sure the PrimeGrid BOINC servers will appreciate the reduced load from this challenge vs. the previous one.

As with the GFN challenges in January, you'll notice a large number of errors. And, just as with the GFN tasks, those errors represent a small number of hosts that are returning a prodigious number of errors. The number of errors isn't in itself very significant.


I had a Linux install blow up and contributed nine of those errors :/ It's all better now so hopefully my machines will behave from here on out. I'm sure the PrimeGrid BOINC servers will appreciate the reduced load from this challenge vs. the previous one.


The servers really don't care. It's a few more records in the database and that's not a problem.

From inside the terminal app, run:
sudo nvram SMT=0

It has survived reboots and one system update. Happy crunching!


Just an update on this for Mac users - this worked on my 2009 Mac Pro with Mavericks, but did not work on an i7 Mini with Mavericks :( And in doing more searches for the Mini it looks like using the tool in Xcode is the only thing that works - except it doesn't survive a reboot :(

The good news is it keeps all 8 "cores" visible so if you set PrimeGrid to cruch with 50% of the CPU's that still works with no modification. But to get that extra boost if you want to disable HT you have to manually go in and disable them again.

To do it, download Xcode from the app store, then right click on Xcode (in your Applications folder) and select "show package contents". Once it's open click on contents, then applications and finally open Instruments. Once you have the Instruments app open, open the preferences for Instruments and mid way down you will see a checkbox for "Hardware Multi-Threading". That's it.

Hopefully there will be a new way via EFI eventually to turn it off. The people who use ProTools and other audio software are up in arms over this - apparently we aren't the only ones who see the value in turning HT off :)

Michael, do you have an estimate for the memory footprint of a single task? I'm wondering if the larger cache sizes of the E5 Xeons might be used to huge advantage by fitting just a single task in their 20+MB cache and avoiding memory accesses entirely.

Bigger cache is absolutely an advantage. For example, even though hyperthreading is not useful for running LLR, it still should be beneficial to buy a Core i7 (with an 8MB L3 cache) rather than the equivalent Core i5 (with a 6MB L3 cache) just for the 33% larger cache.

The server chips DO benefit from both larger cache and more memory channels. Of course, there's lots and lots of different Xeon CPUs, and not all of them have more memory channels or larger caches, but those that do will run LLR faster.

In general, LLR running on an Intel AVX CPU is limited by memory speed. The AVX algorithm is so fast the memory can't keep up. Anything that speeds up the memory -- faster memory chips, larger cache, or more memory channels -- will speed up LLR.

The cache doesn't need to be large enough to hold the entire LLR data. The larger it is, the better, even if it can't hold it all. It won't hold it all: If you hit the properties button in the BOINC manager with a PSP task selected, you'll see that it uses about 50 MB. Each.

We have passed the 1000 tasks threshold! As of right now, 1012 challenge tasks have been successfully returned.

By comparison, normally about 120 PSP tasks are returned each day. That's not a great comparison, however, because that 1012 only includes tasks which were sent out starting three days ago and aren't due back for another 18 days. Just under 10,000 challenge tasks are currently being processed. Including non-challenge tasks, 1385 PSP tasks have been returned since the challenge started. All in all, this is fantastic progress!

You've made it clear that running just one PSP workunit at a time makes it faster than running two at a time on a hyperthreaded CPU core, and also faster than running two or more at a time on a multi-core CPU with all the cores sharing the same memory cache.

However, this does not make it clear whether running many workunits, one per multi-core CPU and then do it again when the first one finishes, is faster than running them all at once, either one per CPU core without hyperthreading, or running them all at once, with hyperthreading used to allow two per CPU core at once. Could you make this clear?

Without making this clear, it's hard to tell whether to reduce the number of workunits running at once will increase or decrease the total throughput of a multi-core CPU. It's clear, though, that decreasing the number of workunits running at once near the end of the challenge is likely to give then more chance of finishing before the challenge ends.

Could you make this clear?


As clear as I can make it:

A) Turn off hyperthreading.

B) Turn off hyperthreading.

C) If in doubt, refer to A and B. :)

The other question is whether to leave one (or more) cores idle. That's not an easy question to answer, because it will vary from computer to computer, depending on the CPU, the memory speed, the memory timings, and possibly the the motherboard chipset. The only way to know for certain what works best on your computer is to test it with all cores running and then with one or more cores idle. Do a little math and then use whatever works best for you.

So it seems I have to turn HT off.

But how? I have this Acer Aspire M3970 i7-2600, but I can't find any way to disable HT.

I can't see anything in Bios about HT, or number of CPU's.

Is there any other way to disable HT on this computer?

You can make it easyer by setting the CPU usage on 50%...

Not every BIOS lets you turn it off. If the BIOS won't let you turn off hyperthreading there's no other way to really turn it off that I'm aware of.

As was suggested, you can set BOINC to only run on 50% of the CPUs and it will only run on half the threads. In theory, this is similar to actually turning off hyperthreading, but in practice it doesn't work quite as well.

We're about one third of the way through the challenge:

Challenge: Double Top Secret Mystery
(As of 2014-03-06 18:45:41 UTC)

25962 tasks have been sent out. [CPU/GPU/anonymous_platform: 25930 (100%) / 0 (0%) / 32 (0%)]

Of those tasks that have been sent out:

12019 (46%) came back with some kind of an error. [12019 (46%) / 0 (0%) / 0 (0%)]
2364 (9%) have returned a successful result. [2346 (9%) / 0 (0%) / 18 (0%)]
11579 (45%) are still in progress. [11565 (45%) / 0 (0%) / 14 (0%)]

Of the tasks that have been returned successfully:

1722 (73%) are pending validation. [1710 (72%) / 0 (0%) / 12 (1%)]
626 (26%) have been successfully validated. [620 (26%) / 0 (0%) / 6 (0%)]
0 (0%) were invalid. [0 (0%) / 0 (0%) / 0 (0%)]
16 (1%) are inconclusive. [16 (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=16463831. The leading edge was at n=15683076 at the beginning of the challenge. Since the challenge started, the leading edge has advanced 4.98% as much as it had prior to the challenge!

There's 2 other options. You can add <ncpus>4</ncpus> to your cc_config.xml file and/or use ProLasso http://bitsum.com/processlasso/ and set LLR apps to use only odd or even threads so as to have each instance of LLR run on 1 PHYSICAL core each.

There's 2 other options. You can add <ncpus>4</ncpus> to your cc_config.xml file and/or use ProLasso http://bitsum.com/processlasso/ and set LLR apps to use only odd or even threads so as to have each instance of LLR run on 1 PHYSICAL core each.

And on many Linux distros, the utility you want is "schedtool". Free (of course!) download from the repos. It's just a command-line tool; no GUI. It allows you to set the core affinity, "nice" value, and scheduler class. The latter two are not necessary to change for BOINC, as the values are already the proper ones for LLR ("19" and "SCHED_BATCH", respectively).

The effect of these tools will not survive a reboot, and so would have to be reapplied, one more reason it's better to shut HT off in BIOS if possible (there's a separate thread here with that process for Macs).

We've had them by the tail most of the day. Like to get in front of them just in case.

After almost 6 days:

Challenge: Double Top Secret Mystery
(As of 2014-03-07 13:27:39 UTC)

29241 tasks have been sent out. [CPU/GPU/anonymous_platform: 29203 (100%) / 0 (0%) / 38 (0%)]

Of those tasks that have been sent out:

13661 (47%) came back with some kind of an error. [13661 (47%) / 0 (0%) / 0 (0%)]
3521 (12%) have returned a successful result. [3500 (12%) / 0 (0%) / 21 (0%)]
12059 (41%) are still in progress. [12042 (41%) / 0 (0%) / 17 (0%)]

Of the tasks that have been returned successfully:

2283 (65%) are pending validation. [2271 (64%) / 0 (0%) / 12 (0%)]
1212 (34%) have been successfully validated. [1203 (34%) / 0 (0%) / 9 (0%)]
1 (0%) were invalid. [1 (0%) / 0 (0%) / 0 (0%)]
25 (1%) are inconclusive. [25 (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=16512861. The leading edge was at n=15683076 at the beginning of the challenge. Since the challenge started, the leading edge has advanced 5.29% as much as it had prior to the challenge!

In total, about 15K tasks have either been returned or are still in progress. Furthermore, that number has increased by about 1500 since yesterday, which is in excess of 10 times the number of tasks normally done each day.

Keep up the GREAT work!

Not yet. It will be a big deal when we find one.

Bigger, you say? Funny, but I was just looking at that. You might be surprised at how much we've progressed since the challenge started.

In the last week, the tasks have grown in length by more than 1/3rd. If a PSP task took 60 hours to run last week, a new task today will take over 80 hours.

The size of the numbers being tested last week was about 4.5 million digits. Right now, it's just under 5.0 million. "N" has increased from about 15M to 16.5M.

That's huge progress in a very short time, especially considering how large these tasks are.

There are 1891 people and 3447 computers participating in the challenge.

The numbers may be a bit deceiving I still have over 200 of these waiting to be verified that date all the way back to Feb, 21. Judging from that I am assuming many people downloaded many of them in the beginning and they may get aborted when the challenge is over.

Very true. Many computers will download more tasks than they can process and those will time out after 21 days. Of course, many computers will take quite a few days to process each task, or downloaded enough tasks for the entire challenge at the beginning, and those will eventually be returned.

It's hard to predict how many of the outstanding tasks will be returned before their deadlines.

I've already adjusted 3 computers to no longer take tasks. It feels weird this early in the game, but when 2 of computers will take 8-9 days to finish 1 task, I am moving them off after they finish the 1 task per core. I did have one that finished 4 tasks in over 5 days, but since this is only a 15 day, the second set will finish near day 11-12 and no room to get new. My AVX boxes on the other hand will help with cleanup, so I am not moving those. I may pause them after the challenge and install the newer LLR, but since I screw that up most of the time, I may not.

I still should make a decent showing.

These bigger units mean that people who got a big cache at the start & do carry on & complete them all will be processing more units & therefore will get a higher challenge score than someone with a smaller e.g 1 day cache, am I right?

Btw Pooh you're near your 100mlln.

Wrong. :)

The longer tasks have a proportionally larger challenge score. 15 days of crunching the shortest tasks should give you exactly the same challenge score as crunching 15 days of the longest tasks.

There might be a small advantage to running the smaller tasks if your last task just misses being completed at the end of the challenge. If, however, your last task does finish by the end of the challenge, you'll get more points than the guy with the smaller tasks who may have ended up with a lot of idle time at the end of the challenge. It could work out either way. With equal processing power, whomever comes closest to having all tasks finish exactly after 15 days, without going over, would have the advantage. Of course, no two people have exactly the same computers, and the difference in computing power dwarfs minor differences in task scheduling.

On the other hand, if a prime is found, the guy with the large cache is at a massive disadvantage and all the fame and glory will likely go to the guy running with the smaller cache.

FWIW, I'm running with no cache at all. BOINC downloads a new task about 60 seconds before the old one completes.

Yeah the G34's do just fine, the problem is these WU's push them pretty hard, I started popping circuit breakers right after I got the G34's switched over to PSP they went from 1050W @ 3Ghz to 1180W so I had to drop the OC a bit. But clock for clock they do pretty well against my e5-4650 rigs since I have to drop HT on the Intel's actually they beat the Intel’s clock for clock core for core.

Any prime found yet?


To put this into perspective.

So far, we have 2600 tasks returned, and another 12,000 in progress. Sound like a lot?

Since PrimeGrid started crunching PSP, we have tested 155,123 numbers (with double checking, that's over 310,000 tasks) and not one of them has been prime.

On the other hand, one could say we're due...

It will be a very big event when we find one.

This table represents how many tasks are being sent out each day, as well as how many of those have been returned. The deadline is 21 days, and the very fastest computers can crunch the smallest of the tasks in a little under a day and a half under ideal conditions.

The table does not include tasks that have an error; only tasks returned successfully or still in progress are included. Days start and end at midnight, so March 1st includes only 6 hours since the challenge started at 18:00. March 8 includes only about half a day.

+------------+------+----------+ | date | sent | complete | +------------+------+----------+ | 2014-03-01 | 4442 | 2493 | | 2014-03-02 | 2224 | 690 | | 2014-03-03 | 2106 | 605 | | 2014-03-04 | 1835 | 628 | | 2014-03-05 | 1701 | 288 | | 2014-03-06 | 2028 | 57 | | 2014-03-07 | 1992 | 0 | | 2014-03-08 | 780 | 0 | +------------+------+----------+

Michael,

I haven't looked at those numbers closely, but certainly that is true. I'm sure work on SoB has drastically declined, since any computer running SoB is a good system on which to run PSP as well.

Challenges draw a lot of participation (both people and computers) from outside PrimeGrid, but also draws a lot of participation from other PrimeGrid projects as well.

Overall, I think it's a good approach to add PSP to the challenge.

Indeed, especially from an organizational point of view :) As Michael posted, the other day we've done more than 5% in 6 days of what we did up to the start of the challenge in many years. That's an amazing result, even when you factor in the much improved CPUs :)

Yeah the G34's do just fine, the problem is these WU's push them pretty hard, I started popping circuit breakers right after I got the G34's switched over to PSP they went from 1050W @ 3Ghz to 1180W so I had to drop the OC a bit. But clock for clock they do pretty well against my e5-4650 rigs since I have to drop HT on the Intel's actually they beat the Intel’s clock for clock core for core.


1180W from one machine ( 4 x 12 core = 48 core ) or from all yours g34s?

I compared time and my xeon 1230 v3 ( hsw, 4 core @ 3.7GHz, AVX ) is 3x faster, some like ~148 000s/wu for 10 500 pts/wu, but has 3x less core pre cpu.

So 1 x g34 12c @ 3.0GHz = 1 x hsw 4c @ 3.7GHz. Need to check power consumption, but I think it will be around 120 Wh.

Hello !

Sorry for this question, but I cannot find any post about it.

Another team member of L'Alliance Francophone drew my attention on the fact that the points in the challenge don't match with the points earned per WU.

I checked on my side, and there is a 30 % difference.

In the challenge I have about 43956 points, while the total of my 3 WU's should be arround 33821.

Is this done on purpose or is there a problem somewhere ?

Thank You

Kind Regards

Philippe

It's intended, and working as designed.

The credit formula and the challenge formula are similar, but not identical.

Given a number k*b^n+/-1 to be processed by LLR, the challenge formula is:

(log10(k) + log10(b) * n / 10000) ^ 2 * CCF_FFT


whereas the credit formula is:

(log10(k) + log10(b) * n / 10000) ^ 2 * CCF_FFT * MCF * CONJ_BONUS * LONG_BONUS


The only difference between the formulas is the "* MCF * CONJ_BONUS * LONG_BONUS" part, and those numbers don't change, so the only difference between the two formulas is that one is always X percent larger than the other. If you get double the challenge points, you get double the credit, too. Make sense?

(And before someone asks why I don't just make them exactly the same, it's because I don't like making things more complex just for complexity's sake. The simpler it is, the less likely it is to break.)

1180W from one machine ( 4 x 12 core = 48 core ) or from all yours g34s?
.


That is correct per machine the 61xx series G34 are the best cpu's I have had clock per clock, core per core unfortunately they are power hungry. The E5-4650 rigs sip power compared to the G34 I get 25% more cores with the 4650 rigs and they are using 765W @ 3175Mhz on the PSP WU's so quite a difference there.

And just for comparison
G34 61xx @ 3000Mhz. = 464,860.00 Run Time sec. 464,860.00 cpu Time sec. (129 hrs.)
E5-4650 @ 3175Mhz = 550,885.00 Run Time sec. 554,883.00 cpu Time sec. (154 hrs)

Those numbers were the avg. I did on a run of PSP wu's back on Feb, 15 with HT on so as you can see the G34,s are a bit faster at lower clock speeds they just need more juice. That holds true for everything I use them on it is too bad AMD never figured out how to make them more power efficient.

Are (historical) daily Team results (total points progress for this contest) stored anywhere for public view? I know that I can get the current results from the PG main page. But I would like to chart our team's progress from the contest start if possible. I tried Googling and also looked over at BOINC Stats, but couldn't find any historical data for this current contest.

Such information isn't readily available, sorry. If it was easy to get, I'd want to see it myself, too. :)

That's Ok Michael, just wanted to check.

To the other suggestion of looking at that BOINC Stats link, I had found that place, but the data doesn't look right. That site says that our team (EVGA) has 4,262,996 in points for this Challenge. The PG site here currently says we have 2,445,562 in points. I also can't get prior days (if it was accurate for this contest) from that BOINC Stats page.

I usually take a daily snapshot myself at ~ the same time every day, but wasn't "on the ball" this time and just started doing it today. Thanks for the replies though.

I was curious as to why a few of the WU's appear to have very short cpu time compared to all the others, they have been confirmed as valid and credited properly so there is nothing wrong with them is this correct or is there some type of bug or something in the tracking software.

As you can see the first one had (264,802.72 sec run time) and (16.00 sec cpu time)
The second had (265,018.90 sec run time) and (217.00 sec cpu time)
That really does not seem possible to me. There are a dozen or so of these out of around 450 completed PSP wu's about half have been verified valid and about half still pending verification.

Although it's unclear what the cause is, sometimes the cpu time is reported erroneously.

If those happen to be your computers, you are in a much better position to figure out what's causing that than we are. From the server side all we see is that the BOINC client is telling us it took X cpu seconds. If they're not your computers, you can safely ignore it.

I didn't know BOINC Stats carries info on Challenges.
Clicking on the graph symbol on the left hand side leads to a Completed Challenges list that's full of old, incorrect data.
However choosing a number of Users or Teams with the checkboxes then clicking the "Compare" button does give some cool graphs over time of credit and rank.
As an example check out these graphs of the top 8 teams in the Stallion Edition Challenge:
http://boincstats.com/en/stats/11/team/compare/pchallenge/110/0?id[]=1596&id[]=194&id[]=46&id[]=11&id[]=2833&id[]=394&id[]=343&id[]=103
I think it's really cool.

NB: Your going to have to cut and paste the link as message board can't handle the []'s.

Are (historical) daily Team results (total points progress for this contest) stored anywhere for public view? I know that I can get the current results from the PG main page. But I would like to chart our team's progress from the contest start if possible. I tried Googling and also looked over at BOINC Stats, but couldn't find any historical data for this current contest.


http://boincstats.com/en/stats/pchallenge/team/list/112/credits


Unforunately all the PG challenges for 2014 on BS was set up beforehand, not including the
Pony challenge (#2 on the PrimeGrid challenge list). Therefore "The Double Top Secret Mystery Challenge" stats showing on BoincStats gives the numbers for the Pony challenge - and none for the challenge it should show. If no one fix the links, this mistake will continue all through the year. As just means that the stats on BS will be to no use - and only show the total credit for each challenge - and also under the wrong name. ;-D

They are on my computers and It appears to affect all of them a small % 2.5% over time, I am guessing it is a software bug since all of the computers seem to be affected from time to time. It looks like the cpu tracking software freezes but idk.

Starting the challenge i saw FFT-length of 1440K and 1536K, ...with the second bunch of work the first 1600K WU appears, and now 1728K http://www.primegrid.com/result.php?resultid=530896749.

How much we will increase? A WU with bigger FFT-length will also need a (much) longer runtime.

FFT size doesn't only depend on N, so we haven't exhausted all of the lower FFT candidates yet. All of the 1440K candidates are in progress, but there's candidates with 1536K, 1600K, and 1728K FFT sizes that haven't even been started yet. (PSP tasks are generated in "N" order.)

I'm not sure where the next FFT size would start but it's beyond anything currently loaded into the server. We're likely to have to load more PSP tasks before the challenge ends, so it's conceivable we might get to the next FFT size before the end of the challenge -- but it's also possible we might not hit the next FFT size for another 6 months.

Also, computation times don't always go up when the FFT size goes up. In PSP, the 1440K FFT is very slightly faster than the 1152K FFT, and the 1536K FFT is faster than both the 1152K and 1440K FFTs. The size of the number is usually more important than the FFT size, although sometimes there's a big difference in FFT speed. 1024K is a lot faster than 1152K, for example.

Although I stand to be corrected I feel I need to point out what I perceived what I read in the results of the challenge. PSP LLR is known to take over 114 hours to complete and the rules for the challenge states that 'Only work units issued AFTER 1 March will be considered for credit.

Please check results for I have noted that (correctly or incorrectly) some teams have shown result in the hundreds of Thousands within the first few hours after starting the challenge. This could only be if those teams bunkered days before the challenge which would give unfair advantage to the rest of the participants.

If I am wrong, my apologies for I can not prove what I perceived what I read. I am not really into this challenge and therefore it is not that important to me as I joined late, it is just an observation.

Some computers are faster than others. While the average might be 106 hours (I'm not sure where you saw 114), many computers can process these tasks much quicker than that, while others take much longer. The computer I'm typing on right now has been computing these tasks in as little as 35 hours, for example. This is a fast computer, but it's not the fastest participating in the challenge.

Also, so there's no confusion, the challenge score is not the number of tasks completed. It's the sum of the score from each task, and a single task is worth between 13,000 and 17,000 or more points, depending on the length of the task. A score in the hundreds of thousands therefore represents less than 100 tasks. Also consider that not everyone is using run of the mill personal computers. There's several large servers participating with as many as 48 cores. They're not very fast, but they crunch a lot of tasks simultaneously. One set of tasks on a 48 core server is at least a half million points.

You talked about teams having hundreds of thousands of points? I personally have hundreds of thousands. I have 238,900.94 points so far, which represents 16 completed tasks, which is 4 sets off 4 tasks each on this quad core Core i5.

I can assure you that nobody is cheating. The standings only include tasks sent to hosts after the beginning of the challenge. Our server knows when the tasks were sent out, and there's no way for a user to alter or fake that.

I guess that fast ram is paying off.

I finished 8 tasks on one box which I only ran while awake. When I turned off HT in the BIOS of that Intel box two of the 4 cores did not run at all. Very odd so I just left it on. I also did not run at 100%. After those tasks I set it to 25% so only two tasks would download and run and they are running over twice as fast at about 2.2% per hour. I am going to add two more tasks and see what the speed is with 4 tasks. Okay with two more it slowed down to 2.05-2.15% per hour. I7-3770 running in the low 70's C with the four tasks. The chip is only pulling 45-46 watts with that load.

My AMD A10-5800K has about 16 hours left on 4 tasks. It also has only been run while I am awake and not at 100%. It barely hits 60C.

My I7-920 Bloomfield box may just barely make it on the 15th. I may suspend 4 of the 8 tasks on the 14th to see if speeds things to finish 4 anyway if required. it is running 24/7 at 92.5%. That chip runs warm with all cores near 80C.

Not sure if that was a typo, but the challenge ends at 18:00 on the 16th, not the 15th.

Need to pick the collective brains here. This is the first Challenge/contest where I've found the need to manage a given PC's allocation of WUs for a project with all cores still available for processing.

My problem: I have an AMD Server with 48 processors. I've already spent the last (11) days allowing it to run PSP LLR on all 48 processors. Can't do another fully loaded stint and finish by the deadline.

My Desire: I'd like to put 12 of 48 processors on PSP LLR and assign some qty of the remaining 36 processors to WCG (FA@H).

I've attempted to use the "Resource Share" setting for the profile assigned to my 4P Server to manage this desire. I set the profile in PrimeGrid to 32% and the same profile over at WCG to 100%. I know about the "use at most CPU %" setting in the Local BOINC Manager and can set that to 25% to limit PrimeGrid to just 12 processors out of 48. But doing it that way leaves the other 36 processors idling for days and is wasting available resources.

When I tried the above Resource Share settings, here is what I did.

- Set the individual Resource Share settings for the 4P's same profile in PrimeGrid (32%) and at WCG (100%).
- Set the Local BOINC Mgr to limit CPU usage to 25% of the processors just to initially limit PrimeGrid to 12 WUs total.
- Enabled new tasks for PrimeGrid and downloaded (12) WUs.
- Enabled new tasks for WCG.
- Result, my active work queue filled up with a bunch more PrimeGrid WUs and appeared to ignore the WCG WUs.

Before this contest began, all this 4P Server ever worked was WCG projects. This was the first time (starting on 3/1) that I have used it for PrimeGrid. Is it possible that some of the "debt management" stuff interceded and gave preference to PrimeGrid anyway?

I successfully pulled off a smaller scale version of this on my 2600K, but with this 4P Server, I'm having no such luck. Any ideas or suggestions would be appreciated because I'd like to get in a few more PSP LLR WUs before the contest ends on Saturday.

BOINC software was designed at a time where most users had a PC with one CPU. Till today it will not do what you want....

Set PrimeGrid to 100% and WCG to 0%.
Disable WCG.
Download 12 WU from PrimeGrid, start the WU's, and set PrimeGrid to "no new work".
Enable WCG.

That is such an common-sense idea that I feel like a complete dummy for not realizing it myself. Thank-you...that will work for me! :)

Three days to go:

11795 challenge tasks returned.

12401 challenge tasks still in progress.

That's almost 1000 tasks returned per day, which is close to 10 times the normal rate. That is also undercounting the actual amount of work being processed because there's tasks the started before the challenge and tasks that will complete after the challenge, neither of which are included in the "tasks returned" number.

Tasks sent each day, along with the number of the tasks from that day that were returned:

+------------+------+----------+ | date | sent | complete | +------------+------+----------+ | 2014-03-01 | 4378 | 3682 | | 2014-03-02 | 2170 | 1388 | | 2014-03-03 | 2035 | 1284 | | 2014-03-04 | 1805 | 1141 | | 2014-03-05 | 1670 | 1006 | | 2014-03-06 | 1962 | 1335 | | 2014-03-07 | 1888 | 1085 | | 2014-03-08 | 1543 | 611 | | 2014-03-09 | 1542 | 601 | | 2014-03-10 | 1464 | 439 | | 2014-03-11 | 1599 | 247 | | 2014-03-12 | 1388 | 54 | | 2014-03-13 | 827 | 0 | | 2014-03-14 | 391 | 0 | +------------+------+----------+


It's interesting and encouraging that more than 75% of the tasks from the first day have already been returned. The deadline on those isn't until the 22nd.

As you can see from the number of new tasks sent out on the 12th and 13th, the work being sent out is tailing off as the end of the challenge draws closer and it becomes too late to finish additional tasks. (About 10 minutes from now this computer will download the last task it can finish before the end of the challenge.)

Which makes for a really nice segue into this public service announcement:


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.

(My thanks to our esteemed Challenge-Meister [DPC]Charley for that announcement, as well as for all the work that goes into organizing these challenges!)

Thanks for the post Mike. Good to see those numbers and how many have already been returned! :) I'll be returning one more unit before the end of the challenge and after that it's time to get cleaning :)

Here's some more numbers, with about 6.5 hours still to go:

Challenge: Double Top Secret Mystery
(As of 2014-03-16 11:29:25 UTC)

55173 tasks have been sent out. [CPU/GPU/anonymous_platform: 55078 (100%) / 0 (0%) / 95 (0%)]

Of those tasks that have been sent out:

29683 (54%) came back with some kind of an error. [29678 (54%) / 0 (0%) / 5 (0%)]
15958 (29%) have returned a successful result. [15875 (29%) / 0 (0%) / 83 (0%)]
9532 (17%) are still in progress. [9525 (17%) / 0 (0%) / 7 (0%)]

Of the tasks that have been returned successfully:

4869 (31%) are pending validation. [4839 (30%) / 0 (0%) / 30 (0%)]
10807 (68%) have been successfully validated. [10754 (67%) / 0 (0%) / 53 (0%)]
66 (0%) were invalid. [66 (0%) / 0 (0%) / 0 (0%)]
216 (1%) are inconclusive. [216 (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=16801223. The leading edge was at n=15683076 at the beginning of the challenge. Since the challenge started, the leading edge has advanced 7.13% as much as it had prior to the challenge!


There's two things I take from those statistics. The first is that we're going to finish with over 16 thousand challenge tasks returned, which is nearly 10 times the normal amount of PSP work and doesn't include non-challenge tasks that also occurred during the challenge. That's also more than double the number of PSP tasks returned during the last challenge.

The second is that "N" increased by over one million!

Cleanup Status:

16-Mar: Double Top Secret Mystery: 5080 tasks outstanding; 4195 affecting individual (296) scoring positions; 4398 affecting team (98) scoring positions.

Although there is a lot of cleanup to be done, almost all of it is already in progress and there is not a lot of cleanup work available. No special effort is needed to help with the cleanup. The amount of cleanup work waiting to be sent out is shown on the home page in red, and as of right now there's hardly any. Feel free to crunch whatever you want to crunch!

Results after deadline?

At the end of the challenge i was listed "place 16", now 17. How could this happen?


After the challenge ended, I noticed an error in the scoring formula. The correction lowered everyone's challenge scores by a small amount, but the adjustment was not the same for everyone. In a few cases where people's scores were very close together a change in position was possible. That's what happened here.

My apologies for any confusion or inconvenience this has caused.

I finally found out how to turn off hyperthreading on my computer where it is normally used. There is no program under Windows 7 that can do it, and no way that's mentioned in the help file. Instead, you have to go into the menus available after a restart or reboot, but before you tell it that Windows is the operating system you want to start (and before it chooses Windows by default), and one of those menus allows turning off hyperthreading.

I then found that, for my computer, turning off hyperthreading makes the workunit complete in approximately half as long. It also nearly stops the flashing of the light indicating drive accesses. Therefore, anyone else who's using an SSD drive as their main drive should test whether turning off hyperthreading actually speeds up the PSP workunits enough that more of them will be completed within a fixed time period with hyperthreading turned off.

That's the BIOS you're talking about, and that's the only way to turn off Hyperthreading. Unfortunately, not all BIOS's allow you to turn off Hyperthreading, and in that case there's no way to do it.

Hehehe, well the unreturned units of the first day(s) are now timing out. So I'd expect there to be "new" clean-ups available every day, all day during the next 15 days :)

We just hit the deadline for the tasks at the beginning of the challenge, so those tasks that were simply abandoned will have just timed out. We typically send out about 120 per day, but we'll probably also see more expiring tasks come back into the queue during the next two weeks.

Now would be a good time for people who want to help with the cleanup to grab some PSP tasks.

It's also a good time for an update:

Cleanup Status:

16-Mar: Double Top Secret Mystery: 5080 tasks outstanding; 4195 affecting individual (296) scoring positions; 4398 affecting team (98) scoring positions.
23-Mar: Double Top Secret Mystery: 3246 tasks outstanding; 2640 affecting individual (285) scoring positions; 2259 affecting team (84) scoring positions.

I wonder why this task was sent to me yesterday, a week after validation. Couldn't the server cancel unneeded, unsent tasks?

Also, how about an update on the cleanup?

Yes, that certainly seems a bit odd. It's not obvious at first glance what's happening there.


Or, not so odd. It seems I can't add today.

The second completed task was late and came in two days after the deadline. The server created a new task once the deadline was exceeded.

However, because of a substantial backlog of replacement tasks resulting from abandoned challenge tasks, the server didn't get around to sending that task out until yesterday. That particular task did not involve a pending task in scoring position, so it was a lower priority than tasks that could potentially change a scoring position in the challenge. It had to wait before all of those tasks were sent out.

Feel free to either abort it or complete it at your discretion.

Thanks for your reply and the update.

That particular task was nearly done so I allowed it to complete. I did abort another just like it.
