Tour de Primes 2022
Welcome to the 13th annual Tour de Primes. 2 is the first prime number...and the only even one. This makes it unique among prime numbers. Therefore, February is declared Prime month...being the 2nd month of the year. :) And there's no better way to pay homage to a prime number than to go out and find one. :) More precisely, a Top 5000 prime.
Special rule for 2022: Even if PPSE drops off the T5K list, it will still be eligible for TdP.
For the month of February, an informal competition is offered. There are no challenge points to be gained... just a simple rare jersey at the end of the month to add to your badge list. No pressure or stress other than what you put on yourself. :)
For 2022, we're bringing back the badges introduced in 2018:
 Red Jersey -- discoverer of largest prime
 Yellow Jersey -- prime count leader (tiebreaker will be prime score)
 Green Jersey -- points (prime score) leader
 Polk-a-dot Jersey -- on the 19th of February we'll have a "Mountain Stage" and award the Polk-a-dot Jersey to the one who finds the most primes on that day (tiebreaker will be prime score for that day).
 Prime badge -- awarded to everyone who finds an eligible prime during the month of February. This is a counter badge, so if you find more than one prime it will show how many you've found, up to 99.
 Mega prime badge -- awarded to everyone who finds a mega prime during February. This is a counter badge.
 Mountain Stage prime badge -- awarded to everyone who finds an eligible prime during the Mountain Stage. This is a counter badge.
 Mountain Stage mega prime badge -- awarded to everyone who finds a mega prime during the Mountain Stage. This is a counter badge.
Results will be available at http://www.primegrid.com/challenge/tdp_2022.php.
As we've done for the last couple of years, there will also be a "just for giggles" Double Checker scoreboard at http://www.primegrid.com/challenge/tdp_2022_dc.php.
As with the last few years, for all primes (BOINC and PRPNet) we're using the new reporting system whereby the prime's date of discovery determines whether it's eligible for the Tour de Primes. Prior to 2014, the date of verification for BOINC primes was used while the discovery date was used for PRPNet primes. The current system is more intuitive and fairer.
Note that SGS-LLR and GFN-15 are too small to be reported to the Top 5000 primes list and are therefore not eligible for the 2022 Tour de Primes.
Currently, the fastest opportunities to find Top 5000 primes is with the PPSE (LLR), and GFN-16 (65536) projects. Of course, should someone find a prime in the mega-prime searches, this would certainly give them a good shot at the green or red jerseys. Not a guarantee, however, as in 2021 there were 67 mega primes found in the Tour de Primes. Overall, in 2021 we averaged over five mega primes per week for the entire year, so you might need more than "merely" a mega prime to take home green.
All ports in PRPNet are available for the competition.
To participate in BOINC PPSE (LLR), GFN-16, or any other eligible LLR or Genefer project, all you have to do is select it in your PrimeGrid preferences. AP27 sequences are not reportable at T5K, so are not eligible for Tour de Primes. WW primes are also not reportable to T5K.
Sieve projects don't find primes, so PPS-Sieve can't find anything in TdP.
Good Luck, have fun, and enjoy! :D

Tips and Strategies:
Tip #1: For all GFN and for PPSE, he (or she) who finds the prime FIRST is the discover of the prime. It's a competition between you and your wingman. While having a fast computer helps, your computer is only useful when it's running a task. If you have a cache of tasks sitting on your computer waiting to run, chances are your wingman will return the task before you've even started it. Setting both BOINC cache settings to "0 days" is strongly recommended. People with slow computers find primes all the time because their wingman downloaded the task yesterday but won't start running it until tomorrow. Set your cache to 0 days!
However, larger LLR searches (PPS or larger) use LLR2, and you're not competing against another user to be first. For LLR2 projects, tip #1 does not apply.
If you're going to ignore tip #1 for GFN or PPSE, don't even bother reading the rest. Seriously.
Tips for LLR:
- Your mileage may vary. What works for me may not work for you. Before TdP starts, take some time and experiment and see what works best on your computer.
- If you have a CPU with hyperthreading, either turn off the hyperthreading in the BIOS, or set BOINC to use 50% of the processors. (But see below for exceptions.)
- 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.
- Use LLR's multithreaded mode. It requires a little bit of setup, but it's worth the effort. Follow these steps:
- Use multi-threading on larger tasks. What constitutes "larger" varies according to how fast your CPU is and your personal tastes.
- It's no longer necessary to use app_config.xml to set up multi-threading. On the PrimeGrid preferences page, set "Multi-threading: Max # of threads for each task" to "No limit" to use the maximum number of threads for each task, or select a specific thread count if you prefer.
Tips for GFN:
- Only run GFN on a GPU. Use your CPU for LLR tasks where it will be much more efficient.
- Unless you have a really slow GPU and a really fast CPU, leave a CPU core free to service the GPU. You'll want the more powerful GPU running at full speed, even if it slows down the CPU somewhat. A hyperthread should be sufficient if your CPU supports hyperthreading. For example, on a 4 core CPU (without hyperthreading), you could set BOINC to "use 75% of the CPUs" to reserve one core for the GPU.

Even if PPSE drops off the T5K list during TdP, it will be eligible for TdP for the entire month.
The PPSE leading edge is like a person climbing on a ladder while the ladder is constantly moving downwards. The steps on the ladder the PPSE climbs on, are (among others) 3-4 years old GFN-16 entries. What constantly pushes the ladder further down is all the new primes that are being reported on more prominent places on the Top 5000.
It is hard to predict if the PPSE leading edge will drop off the Top 5000. Soon. Or ever.
One day, PPSE (growing exponentially) will overtake GFN-16 (growing polynomially). But this could happen while both subprojects are off the Top 5000 list, or while both are still on it.
It all depends on how many people decide to do PPSE, and on how many people do work in fruitful (not, say, DYFL) projects producing primes that "move the ladder down".

Also of interest in this tour is the half-mega-digit limit. At some point, every prime in the Top 5000 will have at least 500'000 digits. (And at some point, PPSE will go over 500'000 digits.) /JeppeSN |

I don't think it's that hard to predict. I think it will fall off the T5K in mid-late February, and I would be very surprised if it stays on forever.
Between this time last year and the end of TdP, PPSE grew by about 6300 digits, while about 320 larger primes (262 of them on PG) pushed it down; the net effect was falling 200 ranks. It is currently right around 4900th place at 498k digits. If 2022 were like 2021, it would reach about 504300 digits (climbing 150 ranks), but the T5K cutoff would climb to 506800 digits (70 ranks above it).
While in principle people could #SavePPSE for the duration of TdP by running it ~50% more (or by running GFN16 and other small projects less), I think its only real hope in the long run is for LLR2 to be enabled. (This won't happen during TdP, but might happen later.) Without LLR2, once it falls out of T5K, people will have less reason to run it, so its fall could be accelerated. Having said that, it should rise back up and possibly back into the T5K as it approaches and passes GFN16. |

I don't think that it is so hard to predict. As indicated by Ravi, PPSE will drop off T5K in February.
Here is the number of new primes larger than PPSEs added to T5K per month in 2021:
Jan: 87, Feb: 283, Mar: 62, Apr: 36, May: 94, Jun: 43, Jul: 131, Aug: 79, Sep: 70, Oct: 61, Nov: 59, Dec: 86.
That's about 1100 primes in 2021.
It is difficult to imagine that PPSE would be able to be back into T5K before the discovery of 5000 megaprimes.
Also of interest in this tour is the half-mega-digit limit. At some point, every prime in the Top 5000 will have at least 500'000 digits.
With 283 primes > 500k digits added in February 2021 and 4866 known primes > 500k digits, this milestone should be achieved during TDP. |

#SavePPSE
At least until Mountain Stage Day, so we can get those last TdP badges! 😃 🏅
I'll even commit to running CPU on it exclusively until then, and forgo running GFN-16/17 while PPSE is still in the Top5K.

The initial announcement specifies " Even if PPSE drops off the T5K list during TdP, it will be eligible for TdP for the entire month."
This does leave open the possibility that PPSE will drop off of the T5K list *before* the TdP, but this seems unlikely (if that is indeed even the intent).

When gurus Ravi and Yves agree PPSE will drop under 5000th during February, it must be correct.
It is going to be a bit tricky for the people who report to Top 5000 when the leading edge stands very near 5000th while many new ones are discovered each day. There are going to be primes reported that survive only a few hours before being pushed out. Right now, the PPSE primes falling off the list are less than 70 days old. These entered near position 4750th.
During the tour, PPSE is run much more than normally. But at the same time, subprojects just above PPSE in size, including GFN-16, are also run more than otherwise.

When PPSE drops Top5K, next project is GFN16 to post T5K primes.
The only other non-MEGA is PPS, 954k digits as of now - and closing on PPS Mega as well.
We will have GFN-16 as entry-level primes and then only MEGA in future.
Or new project needs to be introduced...

How about SR3?
(For those not familiar with SR3, that's a joke. SR3 has an absolutely ridiculous number of k's to be proven. There's over three quarters of a million k's remaining.)

And here I was thinking that SR5 has always been a tall order. I won't be shooting for an SR5 during TdP, but I will probably focus most of my efforts the remainder of the year on it.

FYI, that count comes from here: http://www.noprimeleftbehind.net/crus/vstats_new/crus-unproven.htm. I know because I wrote the code that generates the tables on this page. If one sorts by relative difficulty, then you can see the conjectures that are harder than R5 and S5, which are currently worked on by PrimeGrid. IMO, these are the best options for PrimeGrid to take on as it is unlikely that any sane person would try to work on them on by themselves. I took most of R3 to n=100,000 and most of S3 to n=25,000. So that tells you how "sane" I am.
For S3 about 75% of the k will be removed by primes under 50,000 digits. Unfortunately it would require a lot of manual sieving and testing. The sieving would need to be broken down into a few thousands of k at a time to avoid generating overly large files used for testing. srsieve2cl would be the way to go with sieving. It is significantly faster than any other option that I am aware of. With how quick the tests are, standing up a server might be work than it is worth, at least for n <= 50,000, if one considers the amount of disk space needed for the database.
But if PrimeGrid is interested it should coordinate with gd_barnes over at mersenneforum to avoid poaching or stepping on the toes of others who want to search for primes independently.[/list] |

Yes, it is a lot of numbers of k's to be proven, HOWEVER, R3 in itself is "much easier" than R2 to prove. Everytime you double n, about 46% of all k's are removed due to having a prime, so when it comes to prove R3, as insane it may seem, it is still not far fetch.
At n=1M we will have about 15,820 k's remaining (removed about 84,915 k's)
At n=10M we will have about 2,205 k's remaining (removed about 13,615 k's)
At n=100M we will have about 307 k's remaining (removed about 1,898 k's)
At n=1G we will have about 43 k's remaining (removed about 264 k's)
At n=10G we will have about 6 k's remaining (removed about 37 k's)
At n=100G we will have about <0.9 k's remaining (removed about 5 k's)
At n=1T we will have about <0.1 k's remaining (removed about 1 k's)
So with a bit fortune, R3 will prove around n=100G and most likely before n=1T.
Due to the amount of k's that need handling before n=1M, it would make up for a good PSA project. For ages, once level is good enough for BOINC, the project would be interesting for those who want to run small and fast workunits :)
It is definently worth a consideration for Primegrid in near or shortterm future :)
Take care everyone. |

Right now there are 1,230 known mega primes. Last year we found 269. If that rate continued, only mega primes would be in the Top5K within about 14 years. I expect that rate will increase.
So, if you want to introduce a new project for entry-level primes, maybe it should be one that will take less than 14 years? Maybe much less? |

I believe it will that less than 14 years for PPS close the gap to PPS Mega.
By then, there will be solely GFN16 eligible to T5K...unless we introduce new project.
So, I'm more concerned about PG not having non-MEGA candidates and still T5K primes than T5K with only MEGA...which will eventually happen as well, but later on.
Bottom line - there will always be primes to hunt.

PrimeGrid is not alone, 355 megaprimes were found last year. The number of known megaprimes per year is an exponential function.
It can be accurately approximated using the simple formula n = 1.4^(Y - 2000), where n is the number of megaprimes and Y the year.
Then the number of megaprimes found within Y is about (1 - 1/1.4) · 1.4^(Y - 2000) = 2/7 · 1.4^(Y - 2000). With this formula, the actual and expected number of megaprimes per year are:
Year Actual Expected
2007 3 3
2008 8 4
2009 5 6
2010 4 8
2011 11 12

2018 116 122
2019 174 171
2020 233 239
2021 355 335
The estimates for next years are

Thanks Bill
Still having download issues with CPU and GPU tasks.
I will have 1 or 2 GPU tasks and 2 CPU tasks running but sometime it downloads a 3rd GPU task instead of a CPU tasks and then sits waiting to run while the other or 2nd CPU task never downloads.
It looks like I will have to way over MT tasks just to keep only tasks running and none waiting.
But then I have One GPU and One CPU task set to run but never get a CPU tasks.
Running 16 and PPSE or PPSMega or 17 and PPSE or PPSMega.
I added <max_concurrent>#</max_concurrent> to see if this helps!. It is Not Helping. |

I am seeing more of an issue of getting PPSE Tasks and this might be why.
Or just downloading CPU tasks over GPU tasks.
Looks like I can only run one or the other CPU or GPU Tasks now.
Going back to boinc_7.16.11_windows_x86_64 to see if it works any better |

I know there was a reason I stayed with and rolled back to BOINC 7.14, maybe that was it???
Can't hurt to roll back to BOINC and see if it helps. Can always go back to 7.16. |

Had this issue last year with the Tour De Primes.
The only quick solution I could come up with, was to setup 2 instances of BOINC, one for CPU and one for GPU on the same computer.

Yup, look at the home page.
That being said, the only projects, that find primes, that are *NOT* mega primes are:
SGS (not eligible for TdP)
PPSE
PPS
GFN-15 (not eligible for TdP)
GFN-16
Everything else is a megaprime.
Projects that don't find primes (or at least not big primes):
AP27
WW
PPS-Sieve

Thanks, I did not know you could do this.
I am going to see how to do this being when you update the software you cannot make changes and only updates what is installed.
What's your "Job Control and Multi-threading" settings in preferences for that venue?
Like on one rig I have 1 GPU and a 10 Core CPU so I set to run 2 Task and have the MT set to 6. This would download 1 GPU task and 1 CPU task, while a GPU task is running and the CPU reports in it then downloads another GPU task and Not a CPU task so I end up with a GPU task waiting to run and no CPU task.
I always roll back to 7.14 for TdP. It's the only way I've found to avoid that work unit sitting there waiting.
This causes all kinds of issues with other BOINC Projects, so it takes a lot of work fixing other projects. |

I don’t run any other projects during the Tdp.
Yes it’s a headache to change all my pc’s though.
Yay… the challenge starts just in time for a heatwave in the East coast of Aus :(

PG often run into task problems with both CPU and GPU enabled at the same time.
You either get too many CPU tasks, and starve your GPU, or too many GPU tasks, and starve your CPUs.
The solution is to NEVER run PG with CPU and GPU switches set at the same time.
The method I use is to decide which CPU and GPU tasks I want to run. Then determine if CPU or GPU tasks runs longer.
Then select CPU or GPU only for the longer running task, and using Job Control, select the number of long running tasks I want to download.
After downloading my longer running tasks, I switch CPU/GPU switches to the shorter task only,
and bump Job Control by the number of shorter tasks I want to download.
And then I leave it alone until I need to replenish my longer running tasks.
Then I flip my CPU/GPU switches, replenish my longer running tasks, and then switch the CPU/GPU switches back.
If your long running tasks run for a couple of days, or you have a large enough queue,
you can determine how often you need to replenish your long running jobs.
And you never have to worry about running out of short running tasks again!

That makes this event kind of a waste that PG knows this is a problem.
I would think that PG should have fixed this KNOWN Issue a long time ago.
I only run Tasks on hand and Never have tasks waiting to run. |

Yep. Everything I tried didn’t work except for rolling back to 7.14.
After the TDP is over, I’ll go back to the current version.

For the most part all but one rig is running fine with both GPU and CPU Tasks, only my Z590 RTX 3090 rig has issues running both, sad that I can only run only my GPU for this event. |

We're cooking now! Very toasty lounge room.
I am baby sitting 2 computers in particular.
The 3090 and 9960 was losing the plot - 96 degrees on the mosfets on the MB and over 80 average CPU temp. Another computer - it's 2080Ti seems extra keen. Both GPUs I've reduced power to the them - I think I'm trying 75% now.
There are 2 solutions for the CPUs - run most cores with 2 thread tasks or about 1/2 to 3/4 cores with 1 thread tasks.
And today is a cool change - in a couple of days it will be mid 30s C.
I think I should turn this room into a sauna. |

Ha!! Try sitting in my study with 6 pc's crunching away LOL.
It's even worse in my garage where the other 2 pc's are. It's 7:30pm and currently 38 degrees in there. I think my Threadripper in the garage is really struggling because for some reason it only has a 1st rate of 13.5% (429 PPSE's done with 58 firsts! :()
I think I'll also shut down my old 7990 GPU as it's not worth the power for a 1st rate of 17%
It's even hotter here in QLD tomorrow. Terrible time of year for this challenge for us southerners who own & run our own hardware. :(

That setting should almost always be left at "no limit". That is probably what is causing your problem.
It's only needed for special circumstances, and pretty much *only* when you're running tasks from multiple projects simultaneously.
I'm the person who added those settings to the PrimeGrid server, and I've never set "max simultaneous" to anything other than "no limit". I've never had the problem you're experiencing.
The purpose of that setting is "I want to run 6 tasks from PrimeGrid and 2 from WCG." It's all but *guaranteed* to fail badly if you're using both CPU and GPU. So don't use it.

Whoops hit the wrong button - not sure why I was trying to hit a button.
I really can't complain compared to that.
I suppose it is just the heat really slowing down your threadripper?
I only have 1 computer using all threads (except 1) and GPU at 100%
I have another GPU at 100% but using 3/4 of the threads.
Then a computer running 2/3 of the threads with GPU at 70%
And the struggler - 6 of 16 threads and GPU at 65%
I seem to have tamed them - each one so picky. |

I agree, setting "max simultaneous" usualy makes thing worse.
But if someone found an easy way to avoid dowloading tasks in advance, I would be grateful if they could share it. I know that running 2 BOINC instances, one for CPU and the other for GPU, is a way of getting around this issue, but it is not always feasible.

Personally, I'm just ignoring the preloading and living with it. But if I wanted to thwart it I would:
1) Use the earlier pre-bug version of Boinc. I think that's 7.14.xx, but I'm not certain.
2) Set resource share to 0.
3) Manually load the correct certificate file.
Alternatively, yes, you *probably* could use "Max simultaneous" and run 2 separate BOINC installations, one for the GPUs and one for the CPUs, but there's a lot more moving parts that way, there's a learning curve for running multiple BOINC installations, there's a lot more things to screw up, and a lot more things to manage on an ongoing basis. It should be possible, but it's not the way I would do it.

Man, I had to do a quick double take, there. My garage is also 38 degrees and I couldn't think why a computer would hate that! Then I realized you were down under, while I'm up north in a Fahrenheit country. (And if AtP didn't have its minions running all over my neighborhood, I would actually put a rig or two in there).
My furnace is hardly running at all this month. I think it's actually cheaper to run PG to heat the house during TdP than it is to buy heating oil at current prices...

I'm jealous of this guy, whoever he is, with his Apple M1 processor.
I got to thinking, M1 is ARM, and I have a Raspberry Pi 4 (the fastest they make) with ARM. So maybe I could run an emulator and get some primes that way? Well, I didn't get BOINC running, but I got mprime running on one core with Qemu...
[Work thread Feb 1 03:14] Test 1, 400 Lucas-Lehmer iterations of M2621441 using type-2 FFT length 128K, Pass1=128, Pass2=1K, clm=2.
[Work thread Feb 1 03:20] Self-test 128K passed!
For comparison, on one core of my aging Skylake...
[Work thread Jan 31 20:00] Test 1, 36000 Lucas-Lehmer iterations of M7998783 using FMA3 FFT length 400K, Pass1=320, Pass2=1280, clm=4.
[Work thread Jan 31 20:01] Test 2, 36000 Lucas-Lehmer iterations of M7798785 using FMA3 FFT length 400K, Pass1=320, Pass2=1280, clm=4.
[Work thread Jan 31 20:02] Test 3, 36000 Lucas-Lehmer iterations of M7798783 using FMA3 FFT length 400K, Pass1=320, Pass2=1280, clm=4.
[Work thread Jan 31 20:03] Test 4, 44000 Lucas-Lehmer iterations of M7471105 using FMA3 FFT length 400K, Pass1=320, Pass2=1280, clm=4.
[Work thread Jan 31 20:04] Self-test 400K passed!
Apple really pulled off a miracle with their x86 emulation on the M1! |

LOL yep!
That's 100F for you guys :D Poor old pc's.
@Nick..... yeah I dunno why the rate was so bad. It seems to have stabilised now and looks more in line with my other pc's although the 1950X is nearly twice as slow as my 3950X.
I'm now running 4*4 just to get a 1st rate of around 50%. Still pretty bad but meh..... early days.
I'll probably give up on PPSE anyway. Over the last 2 years I think I only found 1 PPSE prime during the TdP.

Turns out the explanation is pretty straightforward! Apologies if it seemed I was accusing anyone of cheating - I was honestly curious and made a ham-handed attempt at a joke.
I think it is funny - I mean, what performance enhancers are available to Prime Gridders?
Edit: I replied to something now deleted - don't know what to do.
2nd edit: I reckon the exact correct amount of coffee may give an edge for changing settings. Everything else is a dehancer. Or maybe eating very well is an enhancer? These could be complicated rules. |

My first MEGA after 4 years of crunching PG. Like yourself though, not always focusing on a MEGA.
I'm pretty happy about it though.
I wonder if it will be another 4 years till I find the next one lol.

Just started Mega.
I'm going to compare computers using ((number of tasks running) / (average time of tasks in sec)) x 1000. Times a thousand so the numbers are easier. The larger the number, the better.
With limited data so far:
Computer 1 (the computer which is struggling) = 3.86
Computer 2 (9960X) = 5.68
Computer 3 (10980XE) = 5.57
I'm waiting on computer 4 - that one will be interesting.
Edit: computer 4 = 5.79
Each of the computers has only run through tasks once - I'll run them for a while and then make choices of number of cores to run. These CPUs cannot quite run all cores of 1 thread Mega tasks in cache. |

It would be really cool to be able to clear the tasks returned in the last 24 hours.
Useful to optimise crunching. |

Huzzah! My first primary mega after many years of PG was also a TdP find.

How likely is it that after about 50,000 WU (PPSE) you don't have a single hit? |

It looks like we are processing 250k PPSE and finding 7.5 primes per day. That would lead, if I am not mistaken :
k 1-q
1 0,00003
10001 0,25921
20001 0,45121
30001 0,59345
40001 0,69882
50001 0,77688
60001 0,83471
70001 0,87755
80001 0,90929
90001 0,93280
100001 0,95022
So for 50 k tasks returning first in a WU, probability of not finding at least one prime is 22%. |

Results are in after running about 100 Mega tasks on each computer (except the first one which is now 75).
The comparison I am using:
Tasks run at once x 1000 / average time in sec
The higher the number, the better.
I remembered about AVX512 offset for computer 1 (set it to minus 5) and will use the worst case - max time, as the average time is a mix of different things.
Computer 1 (9960X - 14 threads) = 4.67 (better than 3.86)
Computer 2 (9960X - 14 threads) = 5.79
Computer 3 (10980XE - 14 threads) = 5.46
Computer 4 (10980XE - 16 threads) = 5.84
Computer 2 has been ahead of 4 - there is nothing between them (edit: very little between them)
I will change computer 3 to 16 threads. |

This is my 3rd year doing the TdP. In that time I've only ever found 1 PPSE prime.
I'd say they are harder to find than you think :)
I notice in my signature graphic it says I've completed over 300K of PPS_LLR tasks for 8 hits :(
I don't have any pc's with AVX-512 though.

That is fairly close to my estimate of 7.5 for 250k, so this seems to be the current rate for PPSE. |

The PPS_LLR stat on free-dc contains all kinds of PPS including DIV and MEGA, so that might cause your stat to be a little lower than what would be expected for PPSE.

I managed to get a PPSE last year and this year, just over 17 minutes apart (and a year). |

For those who didn't notice, Michael Goetz has made some changes and now there is a "Team scoring list" table in the TdP Results page.
It's the 3rd table from top to bottom.
Nice feature.
Thanks, Mr Goetz !

Yes that's correct.
I guess it's not a good example then. If I spent heaps of time crunching DIV or MEGA that would be much harder to find a prime than PPSE.
On another note..... is nobody crunching GFN-21's? I completed some from 8-14th Dec and they are still waiting on validation. That seems like a long time?

That stupid ratio I did before is exactly the same as comparing tasks retuned in the last 24 hours. Maybe it could be very slightly more accurate, but very much not worth it.
(I have to deal with this 24/7 except every 2nd Sunday where 2nd head allows me to sit in the fridge with my favourite beers chilling)
OK - Mega tasks returned in the last 24 hours
Computer 1 (9960X - 14 threads and minus 5 AVX512 offset) = 410
Computer 2 (9960X - 14 threads) = 476
Computer 3 (10980XE - 16 threads) = 477
Computer 4 (10980XE - 16 threads) = 481 |

That is not because nobody is crunching them. It is because these particular tasks happened to be sent to people who are spending a long time with them. It does not help that many people (or few) are crunching the same subproject.
When it takes a long time, it is not because there is no-one to send the task to. It is because the task is already sent, and that particular user holds it for a long time.

This is true!
I was amazed at how tng found 4 x GFN-17 MEGA's in 4 days..... then I realised how many GPU's tng uses and I didn't feel so bad lol. :D
I've only got 5 GPU's and only one of those is NVIDIA.
All good fun!

PPSE is now larger than 500000 digits. But it is still moving towards the exit of 5k list. |

Yes! We can see it on the front page. And soon we will see actual primes (PPSE over 500'000 digits). /JeppeSN |

Right, the current rank is around 4950.
But, for this TdP, this won't matter. Any PSSE will count for the TdP. :)

We will have GFN-16 as entry-level primes and then only MEGA in future.
Or new project needs to be introduced...
How about SR3?
(For those not familiar with SR3, that's a joke. SR3 has an absolutely ridiculous number of k's to be proven. There's over three quarters of a million k's remaining.)
Sounds like a challenge.
With presently only 2 digits per badge,
either new badges would have to be widened to accomodate the extra digits,
or 3 SR3 badges can be arranged as base-100 units to make a 3-badge counter.
With the latter option you would get a second counter badge when you pass 100,
and a third badge when you pass 10'000. |

Congrats Pooh Bear 27 on the GFN-18!
That 3090 paid off :D
Not that it means much but fyi, last year there were 8 days between the 2 x GFN-18's which were found during the 2021 Tdp.
In 2020's Tdp... it was 4 days between GFN'18's.
(Watch the 1st rate drop now...lol)

Woke up with 2 PG emails received at the same time, got very excited that I might have had simultaneous finds. They were actually a little more than an hour apart, though, but still, pretty neat.
With one a megaprime, I've reached my TdP goal of a mega and more primes than last year. Now on to some stretch goals!

Excellent work! I got my goal of each of a PPSE and a GFN16. I got PPSE first and moved it onto Mega. When I shut off GFN16, I didn't know it was 1/2 an hour after getting another GFN16 first and also a 2nd. I obviously couldn't have known that at the time. A nice bonus. |

This is a trick I just did.
One of my computers stopped communicating.
When I re-set it, multiple PPS Mega tasks finishing at once which clashed with a quick return of GFN17.
So I paused the PPS Megas that were very close together and set them off at 1 minute intervals.
You won't be getting new GFN tasks while doing this.
But hey why not?
It is not worth the effort to negotiate both keeping new tasks being downloaded & running AND changing the timing of tasks by suspending them. I could do that - it is not worth it. |

Urgh.... I've been hunting for another MEGA both PPS & GFN with nothing for a whole week :(
Those buggers are hard to find.
There must be more people look for GFN-17's as my 1st has dropped by 10% in the last couple of days to around 45%.
I keep telling myself to persist but it gets harder by the day now that we are at the half way point.

Chooka you are better off than me. I may be heading for another 2020 and no primes. I am going for the MEGA primes though so may not get one this year. Good luck all. |

Almost halfway through the month, and I am past the point where I have gotten enough firsts on GFN 16 to have at least one expected prime. Hopefully some show up for me in the next two weeks.

I guess PPSE are only 10 larger primes away (maybe less as I write, considering pending finds) from being bumped out of the top 5k. Will they still count towards TdP scores and badges after that? Asking for a friend :)

It appears the hunt is on for a BIG prime. Going for that RED or GREEN jersey.

For the most part there are only 3 or 4 members that will ever see any T-Shirts or Jersey.
The only one outside of this would be the largest Prime found. |

It may have been to make sure it was in the new day - I sometimes have difficulty with knowing which day midnight is on. Only sometimes. I will think it through. Maybe something that could cause some confusion is, as an example, we consider a Friday night to extend into what is technically a Saturday morning? And as the mountain stage starts on a Saturday morning, it is quite likely that people's Friday nights are being extended with an inability to know which day it is? |

When it is stated entirely like that, it is obvious.
Midnight on say Wednesday is actually the start of Thursday.
