Project description

The goal of GFN-MEGA project series is to find a MEGA prime for each GFN exponent, until software limits allows. MEGA Primes for GFN-17 and above were found or being searched on PrimeGrid. MEGA Primes for GFN-16 and GFN-15 were already found in these series. Now it's a time for GFN-14 MEGA, GFN-13 MEGA and so on. Last project in the series (when we hit software and math limits) is not determined yet, it can be either GFN-12 MEGA either GFN-11 MEGA.

These projects are exactly the same as previous GFN-15 project, so for detailed description and instructions please read top post in GFN-15 MEGA thread: https://www.primegrid.com/forum_thread.php?id=9198 . Everything is the same except:

GFN-14 MEGA:


  • This is a GFN-14, so we're looking for MEGA Prime in form b16384+1
  • Search will be started from bmin = 10841645805132531666786792405311319418846637043199917731144080
  • Project name (for app_config.xml) is gfn14_mega


GFN-13 MEGA:


  • Prime have form b8192+1
  • Search will be started from bmin = 117541283763947820803514936063599937165870515987063348437723855381224452611844232886228245901292532817349347812678728888242
  • Project name (for app_config.xml) is gfn13_mega


Duration of all projects will follow same rules as GFN-15 MEGA - one month after prime will be found. Minimal duration will be 3 months (even if prime will be found faster).

For new users, please note once again that this is not a PrimeGrid project. It's running on separate server. Instructions to join are in the post mentioned above.

Current project status

GFN-14 MEGA: (stopping)
2020-12-05: Project started
2020-12-17: First GFN14-MEGA Prime found
2021-03-05: Work loading stopped, cleanup started.

GFN-13 MEGA: (running)
2021-03-27: Project started
2021-04-03: First GFN13-MEGA Prime found
2021-06-27: No new work will be loaded after this date

Good luck and happy crunching!

A misconfiguration of LLR2 parameters (they were tweaked in special way for more efficient processing of GFN tests) caused invalid tasks to be sent until (estimated) 15:00 UTC. These tasks cannot complete, they will fail during final "checkpoint compression" phase with error message "proof.xxx is missing or corrupt".

In most cases affected tasks should be aborted automatically when one of tasks completes and your computer connects to the server. If you don't wish to wait and you still have tasks sent before 2020-12-05 15:00 UTC (check "Sent" field in your list of tasks on the server), it's recommended to abort these tasks manually because they just will consume CPU time and fail.

GFN Double Silver: Earned 200,000,000 credits (305,042,960)
Message 146254 - Posted: 7 Dec 2020 | 12:32:42 UTC

Here is a bit of probabilities.
The expected number of GF primes in [bmin; bmin + d] (where bmin >> d) is Cnd / (2n log bmin).
The mean gap between two primes is (#primes = 1) 螖b = log bmin 路 2n / Cn.
With mega-numbers log bmin 路 2n = log 10999999 = 2302582.79.
For GFN-14, we have C14 = 8.009684535 then 螖b = 287475.

The range was sieved to pmax = 36路1018. The sieve removed 80% candidates.
If 螖cand is the number of candidates for one prime, we have 螖cand = (螖b / 2) 路 20% = 28747.

Note that we could have used the estimate 螖cand = e-纬 log N / log pmax = 0.5614594836 x 2302582.79 / 45.03 = 28710.

The likelihood of success is L = 1 - e-位 where 位 = #cand / 螖cand.
L = 25%, #cand = 8264,
L = 50%, #cand = 19912,
L = 75%, #cand = 39824,
L = 97%, #cand = 100733.

Here is a bit of probabilities.
The expected number of GF primes in [bmin; bmin + d] (where bmin >> d) is Cnd / (2n log bmin).
The mean gap between two primes is (#primes = 1) 螖b = log bmin 路 2n / Cn.
With mega-numbers log bmin 路 2n = log 10999999 = 2302582.79.
For GFN-14, we have C14 = 8.009684535 then 螖b = 287475.

The range was sieved to pmax = 36路1018. The sieve removed 80% candidates.
If 螖cand is the number of candidates for one prime, we have 螖cand = (螖b / 2) 路 20% = 28747.

Note that we could have used the estimate 螖cand = e-纬 log N / log pmax = 0.5614594836 x 2302582.79 / 45.03 = 28710.

The likelihood of success is L = 1 - e-位 where 位 = #cand / 螖cand.
L = 25%, #cand = 8264,
L = 50%, #cand = 19912,
L = 75%, #cand = 39824,
L = 97%, #cand = 100733.



Thanks Yves

Nice to know :)

Cheers

Rob.

Likelihood of success before Great Conjunction Challenge is
1 - exp(-(4000 + 11000) / 28747) = 40% !!!

It's really interesting to see how both 'normal' and 'mega' GFN14 are being tested at the same time...

A quick success!

On 17 Dec 2020, 12:38:09 UTC, PDW found a prime 10841645805132531666786792405311319418846637043199917731150000^16384+1 (at bmin+5920). Congratulations!

As you can see, bmin is very small. If workunit wasn't timed out and aborted twice before PDW grabbed it, the prime could be found on the first day of the search.

Main goal of project is reached, first GFN-14 MEGA Prime found. Project will be active and new work will be loaded for 3 months since day of the start, until 05 March 2021.

Congratulations! Nice one.

Not sure if I find it relevant to continue until March when the prime has already been found.

It's for WUProp hours. Although finding an exotic prime (even not a first one) can be a good goal itself too.

A quick success!

On 17 Dec 2020, 12:38:09 UTC, PDW found a prime 10841645805132531666786792405311319418846637043199917731150000^16384+1 (at bmin+5920). Congratulations!

As you can see, bmin is very small. If workunit wasn't timed out and aborted twice before PDW grabbed it, the prime could be found on the first day of the search.

Main goal of project is reached, first GFN-14 MEGA Prime found. Project will be active and new work will be loaded for 3 months since day of the start, until 05 March 2021.

Thank you :)

3rd time lucky, 1st and 2nd would be kicking themselves if they knew who they were.

That's also my 2021 goals met a year early :D


I tried to go back and check, but I don't think it was me. I only see one WU in Error state for me, from Dec 5. It was finally completed by Robish, and it was very close to this prime:
10841645805132531666786792405311319418846637043199917731151866^16384+1

Thank you, there's still that obligatory second one left to find, just waiting for stream to post that it is unlikely to happen first !

Today, all candidates below bmin+5920 were returned as composites, so a prime found by PDW is an official first/lowest GFN-14 Mega Prime!

The GFN-14 MEGA prime search is close to planned finish, which will happen on March 05. After this day, no new work will be loaded and project will be shut down after cleanup of all currently loaded and pending tests. The goal of project has been successfully reached, finding 2 mega primes, and few last weeks project was run mostly for peoples who have own goals or need WuProp hours.

GFN-14 MEGA search will be replaced by next project in sequence, GFN-13 MEGA search. It's bmin will be much bigger, but still manageable and, I hope, we will be able to factor resulting b to prove that number is prime (otherwise, we can get mathematically proof only for PRP).

To avoid conflict with PrimeGrid activities (upcoming SoB challenge on March 14 and attempt to finish DIV project before SoB challenge), start of GFN-13 project will be delayed. Estimated start date of new project will be Saturday, March 27. It's possible that GFN-14 MEGA will be completely cleaned up before this point and no any GFN-MEGA tasks will be available for few days. In this case, feel free to join "LLR2 testing" subproject which is currently double-checking suspicious (single-residue) PrimeGrid PPS-MEGA tests and already found one missing PPS-MEGA prime.

GFN-13 MEGA will be started March 27, 2021 at 09:00 UTC

There are not much differences between GFN-14 MEGA and GFN-13 MEGA, so I combined all GFN-MEGA projects into single forum thread and wrote common top post.

GFN-13 MEGA task duration and granted credit will be very close to GFN-14 MEGA. The only difference is an application name for app_config.xml - it'll be gfn13_mega

Like in previous projects in series, mutlithreading (via app_config.xml) is highly recommended for most CPUs, but its efficiency is limited to 4 cores (i.e. using more then 4 cores will not give you noticeable boost, and extra cores will mostly stay idle).

GFN-13 MEGA will be started March 27, 2021 at 09:00 UTC


When I asked, "Would anyone find it interesting to locate the first megaprime for GFN16?", I had not expected this!

The numbers are becoming silly to even write. Should we change notations? For example, the first GFN-14 mega is:
10841645805132531666786792405311319418846637043199917731150000^16384 + 1

This can in fact be written shorter if we allow:
(floor(10^(999999/16384)) + 5922)^16384 + 1

For GFN-13, such a notation becomes even more economical.

What do you think? The Prime Pages do have a few entries where the function floor is used. Maybe we should ask Caldwell?

Is this correct to make them use 4 cores? I'd been running single core on the 14s, I didn't know you could multithread them (shouldn't it default to 4 if that's best, like the main primegrid ones do?):

GFN-13 MEGA will be started March 27, 2021 at 09:00 UTC

There are not much differences between GFN-14 MEGA and GFN-13 MEGA, so I combined all GFN-MEGA projects into single forum thread and wrote common top post.

GFN-13 MEGA task duration and granted credit will be very close to GFN-14 MEGA. The only difference is an application name for app_config.xml - it'll be gfn13_mega

Like in previous projects in series, mutlithreading (via app_config.xml) is highly recommended for most CPUs, but its efficiency is limited to 4 cores (i.e. using more then 4 cores will not give you noticeable boost, and extra cores will mostly stay idle).

Is this correct to make them use 4 cores? I'd been running single core on the 14s, I didn't know you could multithread them (shouldn't it default to 4 if that's best, like the main primegrid ones do?):

<app_version> <app_name>gfn13_mega</app_name> <plan_class>mt</plan_class> <avg_ncpus>4</avg_ncpus> </app_version>



<app_config> <app_version> <app_name>gfn13_mega</app_name> <cmdline>-t 4</cmdline> <avg_ncpus>4</avg_ncpus> </app_version> </app_config>


Yes 4 at most, try this 馃憤

Thanks! That works. I accidentally downloaded loads of LLR2 tests, I had to change my prefs on the server as it seems the server prefers I do those.

My Ryzen 3900XT uses an average of a little over 3 cores when asked to use 4, and my Xeon X5650 uses 2.

New LLR2 application (LLR2 version 1.1.1 2021-02-04, Boinc version 116) is installed (Linux only, Windows will be updated soon)

This version includes major update of gwnum (version 30.4) so it may contain unpredictable bugs (although certification will catch any possible calculation errors). Please report here if you'll notice something unusual.

New version of gwnum has improved multithreading support - is about 10% faster on GFN-MEGA tests in multithreaded setup. Speed of single-code tests is unchanged. Time per iteration on my home PC (4 cores):

Old version: 930 ms/bit
New version: 825 ms/bit

CPU usage also increased from 3.1 to 3.5 (on 4 cores).

Speed of Proth testing, most probably, was not changed, but I didn't tested much.

Also this version should read checkpoint files for tests with b <> 2 significantly faster. This improves speed of checkpoint compression at the end of test, but only in cases when LLR was restarted and checkpoint data had to be read again from disk. (It'll not affect cases when test was run continuously from beginning to end without interruption, because in this case checkpoint data is kept cached in memory and no need to read anything). A function which reads checkpoint data was completely rewritten by gwnum author, it may contain any new bugs, so please report everything unexpected.

Yes, we have a prime! And it's proven. The base was successfully factorized in about a hour using yafu, and prime was proven by pfgw.

It seems to be a first T5K prime for mmonnin. Congratulations! mmonnin, please follow instructions I sent you in GFN Server PM. In short, the best way is just to edit your prime reporting preferences here on PrimeGrid.

And we have second GFN-13 MEGA prime! Congratulations PDW!

Since T5K site is currently under maintenance and reporting is broken, prime was not reported yet. All what I can say now is that base was factorized without any problems in a fraction of a second using YAFU, it had few small and one very big factor (109 digits).

Thanks.

Could depend on how long T5K stays down and not accepting finds.
I could be wrong but I think the time/date of reporting on T5K dictates the order rather than the time/date actually found ?
If that's the case it might be reported as the 1000th when it wasn't ;)

Wow! Third GFN-13 MEGA prime, very close to previous one! Congratulations [SG-FC] dingdong! Very lucky find - according to stats, this user currently did only 64 tasks!

Again, base was factorized without problems. It had only two factors, first very small and second everything else.

Yes, and it's currently recommended (at least until we drop down below n=2M). Application name for app_config.xml is llr2

It depends on CPU. This is a Proth test and it scales well, so Intel is OK with 4 cores. I think that there is no need to go higher - when we finish k=7, tasks will be shorter and multithreading will be less efficient. On Ryzen, number of cores must match chip structure to keep task within single CPU block.

And is this right?

Yes, it's fine. Everything is same for all apps, just change application name.

I can't find Ryzen chip structure anywhere, I've seen it before somewhere. Google is not working! Any mention of "block" gives me water cooling blocks. And structure just gives me general specs and gaming benchmarks. It's a Ryzen 3900XT if anyone knows how they look inside. All my other machines are Intel, from an i5 8600K to an ancient DDR2 thing.

For the 3900XT, your best throughput right now will still be single-threaded. The second best would probably be 3 threads per task; but only if you are using some software like Affinity Watcher or Process Lasso to keep the tasks on adjacent cores in the CPU. The 3900XT can be thought of as 4 separate CPUs with 3 cores each. They can communicate with each other, but relatively slowly, so if you keep the tasks in each mini-CPU (CCX is the proper term in this case), you will see the best performance for multi-threading LLR tasks, as long as you stay under the 16MB cache limit.

Ultimately, for the 3900XT, for the remainder of the 100,000,000+ tasks on LLR2 Testing on Stream's server; single-threaded is your best bet.

And structure just gives me general specs and gaming benchmarks. It's a Ryzen 3900XT if anyone knows how they look inside. All my other machines are Intel, from an i5 8600K to an ancient DDR2 thing.


For the 3900XT, your best throughput right now will still be single-threaded. The second best would probably be 3 threads per task; but only if you are using some software like Affinity Watcher or Process Lasso to keep the tasks on adjacent cores in the CPU. The 3900XT can be thought of as 4 separate CPUs with 3 cores each. They can communicate with each other, but relatively slowly, so if you keep the tasks in each mini-CPU (CCX is the proper term in this case), you will see the best performance for multi-threading LLR tasks, as long as you stay under the 16MB cache limit.

Ultimately, for the 3900XT, for the remainder of the 100,000,000+ tasks on LLR2 Testing on Stream's server; single-threaded is your best bet.

Thanks. Sorry to ask, but can you give me an estimation of what's best for my other machines? They're all Intels. i5 8600K (6 core), Xeon X5650 (6 core + HT) x 2 CPUs per machine, and 3 older ones: N3700 (4 core), Q8400 (4 core), i3 350M (2 core + HT).

Also I'm assuming it's best to turn the HT off?

Do these estimates apply to the MEGA project?

I would guess that the i5-8600k and Xeon X5650 would do best running 3 tasks with 2 cores each, and that the N3700, Q8400 and i3-350M would do best running a single task with all cores, due to their smaller cache sizes.

You can turn hyperthreading off in the BIOS if you want, or you can tell BOINC to only use 50% of the CPUs if you leave hyperthreading on. For the dual Xeon system, it will also be important to use a program like Affinity Watcher or Process Lasso to make sure that the tasks are staying on the same CPU.

These estimates might apply to the MEGA project, but LLR2 Testing is well above that point right now in terms of test size, so they might be a bit off, but they'd probably be close.

Enjoy :)

Thanks very much. I run other projects, but I've started concentrating on one at a time (well one for CPU and another for GPU sometimes). Some projects don't care if HT is on, most go faster with HT, but Prime goes slower. So I'll set Boinc to 100% or 50% accordingly when I change project.

I'll take your word for it on the number of cores per task for each computer, as I don't feel like running a load of tests all day!

Since T5K site is currently under maintenance and reporting is broken, prime was not reported yet.

Everything seems to be working again.
