Anyone else?

🤣 just pick a number between 169686 an 250,000 👍

Lol! I was JUST about to write something similar :D
No literacy for this stuff required. For this particular guessing game it doesn't matter if you're the world's leading mathematician on Generalized Fermat primes or someone who has some D250,000 dice and gives them a roll. My number is based purely on probabilities and Rob's is based on his gut feeling and optimism (at least I think that's what it is based on; correct me if I am wrong :P ). Both are equally valid and equally likely to be correct in this case, so guess away!
P.S. In addition to being between the above range Rob mentioned, the guess should be an even number.
P.P.S. Imagine D&D with a D250,000 die. The DM's life would be Hell XD | |

182486
wow, very specific :)
Ok now i have to go and test it manually.
So (bmin 1814570322693370) + 182486 = 1814570322875856^65536+1
Running......
Will report back when finished.
It's as good a guess as any, as the "closest to" rule applies :)

Nice! I particularly like the last 3 digits, 182486, but I see a missed opportunity here by not going with 180486 :P
Any time someone picks a very specific number I wonder what they know that I don't, and apparently Rob has a similar feeling as he is now testing that one manually, lol! If it comes back as prime, let us know and I'll DC it straight away :) | |

Actually; my curiosity strikes high and I started running it as well. That way we can compare residues straight away if needed :)
Edit: More near-simultaneous posts! Lol! I will cancel the very short-lived test XD | |

As I said, I'm no super math weenie... :-) You said guess, and a guess is what you got! haha. I put a ton of time into sieving for the no prime left behind project several years ago (and another project that the name escapes me). Back before the intel 4core chips were in the game, as in 80286/386 chips. Sieving wasn't the preferred activity then. And that plus this project is my exposure to the prime number game. :-) | |

I'm no math head either, I just do probability and gut mixed. Running a program from command line is basic, not complicated. Genuinely. But familiarity certainly does help. 🙂
Finding primes is addictive. Thank heavens its this and not drugs 😆😆😆🤣

Think I might take my guess back. I dont think one will be found in the range. We may be at this a while. Hopefully I'm wrong! 😥
Edit: by range I mean 74,000.

Getting close to the point where Renix1943's win turn into Rob's win! The mid-point between those guesses is 183,743.
I have pulled my computers off of GFN-16 Mega for now and put them on SGS. I will be in bed when the challenge starts so I want everything on just PrimeGrid before the end of the weekend. Makes it easier to wake up for a few minutes, change some preferences, then go back to sleep ;) | |

Haha, it's just going to slide right on past us all and that means Kellen will be the closest!!! lol.
Yup, it looks like I'm just going to miss the beginning of the challenge. But it's for the good cause it's going to give me more power for the farm :-) I made the trip over to a GOOD computer parts store yesterday to gather more goodies. Theoretically the only thing left to purchase now is one or two killer gpu's so I can keep my garage warm this winter and chase Robish on those primes!! haha
Sadly the last time I was in Ireland was in 1988, so I think all that good luck stuff for me has faded into eternity. :-( | |

Cool.. holiday or business? I had just left school and started college. Where did you stay?
Small sacrifice for moar powah 😆 is totally acceptable and correct decision 🙂👍

At that time I wasw the command master chief on us navy ship, we were in Cobh. We were there a couple of times for a week each. I really enjoyed it. Lovely place and the people were just super! First time was in 87, and then 88. The 88 trip was after we had been up above the arctic circle off Norway. | |

At the present moment there is a ~92% chance that this is exactly what will happen, lol! Still; it could drop at any moment and you or Rob could take the win :)

That's awesome! How did you enjoy your time in the north? We're you there in summer or winter? I spent 8 months working at a mineral exploration site in the Arctic. Got to see both 24 hour days and 24 hour nights. An interesting experience to have had, but one I'm not keen to repeat, lol. | |

We were up there in the late fall, was getting pretty cold and the weather was deteriorating. Had a lot of sick guys. The Northern Pacific isn't nice in the winter either. It falls in that category of been there done that, but not one of those things I'd rather not stand in line to do again. lol. But the older I get, looking back on life, there's many things like that that you see that others never see and it's an amazing world. Everyone doesn't get the chance. So I also count myself lucky to have seen a bunch of it, as you have, and it makes for a full life! :-)
I have a good buddy that was a flight engineer on the c-130's flying back and forth from NZ to Antarctica during the Deep Freeze days in the Navy. He sure had some pretty hairy experiences during those years. Life gets really harsh in that cold part of the world as you've experienced. :-) | |

WOW! command master chief!! Awesome! Lot of responsibility!
Cobh in Cork is really nice part of Ireland however even I have difficulty understanding their accent there :) They kind of sing when they speak :)
It can be easy to assume they're not speaking English at all :)

I just loved it there. One of my favorite spots on the planet. Also lived eight years in Japan, four years in Northern Japan, and 4 years in the Greater Tokyo area. I really enjoyed Northern Japan. Winters got pretty cold there. Also got into Perth, Australia a few times, among a lot of other places. But I often look back with fondness on Cobh. :-) | |

It most certainly can be pretty rough in the far north or south. I think that, until you've been there, it's hard to grasp really just how isolated these places are. Despite the modern world and all of our technology when you are in those places and something goes wrong, you're really on your own. We had some weather related troubles too; ran completely out of food and heating fuel because the supply planes couldn't come in for a few weeks. One of the local Inuit communities (local = 160km away, lol) brought us some fuel, half of a narwhal and a caribou by snowmobile and stayed in our camp until the weather cleared. Despite how crummy it was; I agree with your "full life" view on it! A good experience to have had and something to compare any bad present situation to to make yourself feel better, lol!

Very nice!!! I took Japanese language courses while in university and visited once, but didn't leave the Greater Tokyo area. It was more of an extended stopover on my way back from Korea, but I'd love to go back someday! Can you still speak any Japanese? Mine is very rusty, but I'd like to think I could still get around there :) | |

Lol! We have a place like this in Canada too. Newfoundland is technically English-speaking and part of Canada, but I need a translator half the time to understand the dialect.
This is a music video from one of the Newfoundland rappers in case you want to hear the accent https://www.youtube.com/watch?v=RFs-Qmc3IcU. There is some talking at the start. I should note that this song made it onto the radio here; this is the kind of crazy music you can find in Canada; a song about being forced to choose between your girlfriend and cold beer XD | |

Japanese was also my language study in college. I'm definitely rusty on it now as it's one of those things you really have to keep speaking or it just fades quickly. That said, sometimes I amaze myself when talking with folks as some Japanese will pop into the brain about what we're talking about. Just to start speaking it now I'd have problems, but I'm sure that stuff would start coming back fairly quickly if I was to go over there for a bit.
I got over to South Korea a few times but I didn't enjoy it like Japan. And that kimchi with the fish in it was just too aromatic for me. lol | |

That's brilliant! I believe most of Newfoundland was populated by Irish and its obviously true. I can here a few tweaks that are unique but mostly its an Irish Accent!!! Cant believe hundreds of years later they still have an Irish accent!! Superb!
as for Cork accent...have you ever heard of Sminky Shorts?
Short Funny cartoons by a Cork Guy. Good examples of the accent.

I love these but not sure how well they travel :)
See what you think :)
Edit: ...and yes they're supposed to be stupid :)
Lol! Those were pretty good, especially that first one! I find that the humour of Ireland and the UK is very similar to that of Canada, at least where I grew up here anyway (or perhaps just within my family/family friends). I watch a staggering amount of Monty Python, Fawlty Towers, Are You Being Served?, etc. reruns when I was growing up, and love anything with that type of silliness.
Glad to hear that the accent has remained relatively unchanged in Newfoundland! I'm not too surprised though, given how different it is from the local accent where I live (which doesn't change much across the rest of the English-speaking portions of the country actually). Newfoundland didn't join Canada until 1949 and before that time was a self-governing British Dominion, plus, being an island (and a relatively remote and underpopulated one), has remained pretty isolated even after joining the Canada.
I was curious, so I looked up some distances. The distance from the capital of Newfoundland (St. John's) to Dublin, Ireland is 3,288km. The distance from St. John's to Vancouver, on our west coast, is 5,022km. The city in Canada that is most similar in distance from St. John's to Dublin is Winnipeg, Manitoba, which is commonly considered the half-way point for driving across the country. Newfoundland is closer to Ireland than to much of Canada, lol! | |

Yup, I got in to a bunch of them! So the wiring evolution has started as the electricians are now out in the garage. :-) | |

First time I went to Ireland was in September 1980, with my, at that time to-be, wife, my brother and a friend. Lot's of nice memories.
Among which one of the biggest mystery in my life. Now that I think of it, that was certainly the well-known Irish luck. We were camping and we planted our tent in a field in the middle of nowhere in Clare County. Then we went to town (Ennis, maybe), found a pub, drank a pint of Guiness, drank a whiskey, drank another pint of Guinness, sang folksongs, drank some more pints of Guinness, sang songs in support of IRA (remember the 80's), and so on for some time. And then I drove us back to our tent in a field in the middle of nowhere. And found it without a wrong turn. I still have no clue on how on earth I did that. | |

That's probably the nicest spot, scenery wise in Ireland. Good choice. The burren Co. Clare very rural and mostly unspoilt and things move slower down there, no rush. Really nice spot to visit. :) The only mildly annoying thing is having to stop the car every mile or so to take another breathtaking photo along the coast anyway. Theres just so many picture postcard views and no two alike. :)

Edit: goes past 195,000 Kellen wins 🙂 unless we guess again 🤗 well I kind of already have saying it won't be in the range at all. But shortly afterwards

I think if it hits 250,000 we should all (or at least whoever wants to) guess again, with an upper limit of 1,000,000 :)
If we go past 250,000 then I guess 455,000. Basically just add 205,000 to whatever the lower limit for the guess range is and that's my guess :P | |

Ok I'm going for 375,000 which is an awful long way off (not as far as you Kellen but a guess is just that) hey we all know its a lottery 🙂 and a bit of fun 😉

Another curiosity struck me, so I went to Yves' trusty probability calculator (http://yves.gallot.pagesperso-orange.fr/primes/stat.html) and messed around a bit. If b reaches bmin+290,900 then I'd say we have become quite unlucky with this search. That is the value at which we have equal probabilities of having found two primes in the range searched as having found no primes; 24.31% chance for each of those occurrences (with a 34.38% chance of having found a single prime, and the remaining 16.93% being for finding 3 or more primes).
Let us hope that we find one before then :) | |

Scratch that. Digitalocean decided that I was abusing their systems (no details about what the problem is, just an email from Digitalocean Abuse mentioning "recent atypical account activity") and shut everything down, then locked my account. Trying to get it sorted out, but they don't seem keen to respond. Hopefully things get sorted out before the tasks time out! | |

Lol! That is several expletives more than I used :P
My frustration is predominantly that it's going on 15 hours and I haven't heard a peep from them about my response. Browsing through their support forums and the Aggie the Pew message board though; this seems pretty typical.
This experience did spark my interest in acquiring an AVX-512 capable CPU of my own and I noted this one https://ark.intel.com/content/www/us/en/ark/products/198012/intel-core-i9-10920x-x-series-processor-19-25m-cache-3-50-ghz.html. It is supposed to be released Q4 2019, and is being sold for $750. Not too bad and should be equal to about 8-12 droplets, due to the droplet CPUs being much lower clock speeds and each droplet vCPU is actually 1 hyperthread and not a physical CPU.
If Santa is really nice to me and crams fistfulls of cash into my stocking, perhaps I will start the new year with a new PC :) | |

Nice! After 26 hours and a public forum post on DigitalOcean they unlocked my account, so I can finish the tasks that are on those droplets (unless they lock me out again...). The experience that I had trying to get ANYTHING out of DO though has left me pretty salty, so I'm going to finish those up (again, unless they lock it out...), and destroy the droplets, so it will be a few days before I am back to 16MEGA on my own PCs.
I was looking more into the 10th gen X series CPUs and am pretty blown away by the price point compared to 9th gen. Assuming I can actually get my hands on one, I will throw a 10980XE towards 16 MEGA in the new year :D | |

I was just thinking about this and the goal of the project being to find the smallest proven megaprime. I wonder if anyone (other than myself) would be interested in finding the world's largest sub-megaprime XD
How many leading 9's can the prime have? I propose a small search very close to the bmin value of this project. Perhaps bmin-100,000 to bmin.
I just plugged this into my calculator and log(1814570322593370)*65536 shows as exactly 999,999. I think I need a better calculator.
Edit: Using a better calculator: 999,998.99999843147959 :) | |

That would be cool too. Maybe we can ask stream after this one finishes 👍

Starting in about 10 hours I will have computers unable to complete another GFN-21 during the challenge and will begin moving them back over to GFN-16Mega. I'll help DC that 400+ task backlog of yours, lol! | |

I didn't bother with cpugfn21 and kept everything on 16mega. Thought I might get lucky while everyone on gfn challenge. Sure I'll keep at it till it drops.
I dont think youll get only dc tasks 😳 i think boinc sees to that. 👍

Haha, nope! I certainly won't get only DC tasks, but you do have a pretty good pending queue right now! We will get that sorted out soon. You may have found the prime and we just don't know yet ;) | |

Even though we are pretty close to that magical 195,000 threshold there is still a reasonable chance that you'll win the closest guess! As a matter of fact, there is actually a 1.18% chance that you have already found the prime and it is just waiting for a DC ;) | |

Ah I would think it would appear on T5K as soon as is found. On the other hand even stream has stopped processing them .....hmmmm.
Anyway the magic threshold is almost here ....

And less than 24h later bmin+197012
We are most certainly progressing the leading edge quickly now :D | |

bmin+199512
Almost at 200,000!
I'm not big on following "gut feelings", but I have one right now that says that we found the prime. Not too sure why, but something feels different looking at the stats page. I hope that this gut feeling is right! I may not win the prime, but I'd at least win guessing the range, lol! | |

Here's hoping :) keep an eye on T5K every so often 😉

Cpu, and no time limit, dc issues when your finished yours. Great for slow laptops etc. Put http://boincvm.proxyma.ru:30080/test4vm/index.php into your add project in boinc and you're set 🙂👍oh and select 16mega only .....or have fun with seconds lasting gfn 13 and 14 on your gpu 😉

So is the object here like primegrid to get your result back faster than a wingman or is the double check done as a separate thing?
Have 13 running at the moment. | |

Havn't done 13 or 14 in a while but 16 theres no race like pg. The dc task issues when your (1st) finishes. Yes we all get dcs but I think it's fairer than PG. No pressure to get fast kit. 👍

Welcome aboard Renix1943!
I have found that on most of my computers the best throughput is by running tasks with two cores for GFN-16Mega, although your experience may be different depending on RAM speed and CPU. If you are running GFN-13 or GFN-14 GPU workunits at the same time make sure to leave lots of CPU available as they are extremely CPU-intensive for GPU tasks, and running multiple tasks concurrently will maximize output.
In case it helps, and in case you are interested, here is my app_config.xml for Stream's GFN server for my i7-2600k before I upgraded the RAM. (After I upgraded the RAM from 1600MHz 11ns CAS latency to 2133MHz 11ns CAS latency I found that running 4 simultaneous single-thread tasks was marginally faster than running 2 two-thread tasks.):
<app_config>
<app>
<name>gfn16_mega</name>
<max_concurrent>2</max_concurrent>
</app>
<app_version>
<app_name>gfn16_mega</app_name>
<cmdline>-t 2</cmdline>
<avg_ncpus>2</avg_ncpus>
</app_version>
<app>
<name>gfn13</name>
<max_concurrent>10</max_concurrent>
<fraction_done_exact/>
</app>
<app_version>
<app_name>gfn13</app_name>
<plan_class>opencl_nvidia_gfn_101</plan_class>
<avg_ncpus>0.01</avg_ncpus>
<ngpus>0.1</ngpus>
<cmdline>-x ocl4</cmdline>
</app_version>
<app>
<name>gfn14</name>
<max_concurrent>10</max_concurrent>
<fraction_done_exact/>
</app>
<app_version>
<app_name>gfn14</app_name>
<plan_class>opencl_nvidia_gfn_101</plan_class>
<avg_ncpus>0.01</avg_ncpus>
<ngpus>0.1</ngpus>
<cmdline>-x ocl4</cmdline>
</app_version>
</app_config>
You'll notice that the GFN-13 and 14 tasks show 0.01CPUs use. In reality it is way more than that, but BOINC doesn't handle that command well, so I just cram a tiny number in and control the number of tasks running with the <ngpus> and <max_concurrent> tags. Depending on the GPU I run between 3 and 12 tasks per GPU, and I try to stagger their start and stop times so that one finishes and another one starts every few seconds. This keeps the GPU in a relatively constant use state and also avoids the inefficiency of not having the GPU running during task initialization (which takes about 3 seconds for GFN-13 and GFN-14 tasks, which is a significant portion of their 8 and 15 second run times on an RTX 2070).
That config file should work well for your 8100, and with a tweak to the max_concurrent to "3" should work well for the 8700 too.
As for the 5960X, it will probably run best with 4 concurrent tasks as each task uses about 2.7MB cache, so running 8 tasks on the 5960X would exceed the 20MB cache, but 6 single-thread tasks would still fit within cache and may be more productive than 4 two-thread tasks too.
Feel free to experiment to your heart's content, and if you already know all this, or if you don't want to experiment, feel free to ignore it :D
Have fun and good luck! | |

GFN-13 and 14 are a race, but 16 isn't ;)
I have 1 of my computers running with a 15 minute GFN-13 buffer right now, so you have a good chance of being first if you get one of the tasks from those workunits :) | |
|
|
I should also note that the app_config that I posted helps the throughput of the GFN-13 and GFN-14 tasks immensely by avoiding the benchmarking at the beginning. It ensures that the task is run with the OCL4 transform without having to run any tests. Saves a few seconds per task :) | |

Wouldn't have thought of that, ("OCL4 transform without having to run any tests") super tweaker Kellen, every electron counts😉👍

Thanks for the info. I am just running the 16 mega, nothing else. So single threading is fine for me. :-) | |

Haha; no worries! Turns out that my gut feeling that we had found the prime was also wrong :D
Leading edge is really moving fast now though! | |

bmin+208112
Also I thought it was 74k total, I read back and its 78k total for 1 prime. Not sure if will be but anyway we're about to pass 60k shortly.

I'm getting 64,200 total, but I see that Stream posted that we are expecting 3-4 primes in the test range, and Yves calculator is saying 4.86, so that is where the discrepancy lies. Either way; almost 1/4 of the way finished the search range and gaining speed! :D | |

I hope you are right! It looks like a bunch of people have piled into the search now too, which is great to see. Tasks in progress is through the roof! :D | |

Ok so there are about 156'000 candidates to test in total.
As 1 candidate == 2 tasks, that is at least 312,000 tasks to be done in the full range i.e. up to (1814570322693370^65536+1, lowest candidate with 1'000'000 digits +1000000).
We are at 65526 tasks done. 312,000 total tasks so 21% of total range done.
However it's expected to have 3-4 primes in the search range. So taking 4 primes as best case scenario, we have 4% of total to go, or 12480 tasks.
If its only 3 primes ……..we need to do more sums :P
Although they could be anywhere as we know...….

I'm really hoping that it drops before the end of the month. With February being a time where many people focus on PPSE tasks I think a lot of the computing power will disappear from GFN-16 Mega, plus; the suspense is killing me. I can't wait to see that prime show up on T5K :D | |

Absolutely. at this stage I don't care who finds it, even someone with 5 tasks will do 😉

Yup. I put a couple systems back on it. Was running into some heat issues for a while and then sorta forgot to turn them on again when it got cold again. duh! | |

If we go past 250,000 then I guess 455,000. Basically just add 205,000 to whatever the lower limit for the guess range is and that's my guess :P
I'm on the edge of my seat for JeppeSN's answer to your question about the expected distance always being the same no matter how far we progress!
Ultimately it is because there is no relationship between one prime and the next prime, and in order for the Poisson distribution to add up to 1 expected prime, at this prime size and for GFN16, you require an average progress of 205,000 for the b value (which is the reason I picked that number and why my guess is always that far ahead of whatever bmin someone selects, lol). This number will increase as b increases (very, very slowly at the b values we are at), but I've never seen a really good breakdown of exactly why.
It's one of those things that I understand enough to use it, but not enough to explain it, and I'm really hoping JeppeSN changes that! I'm glad you asked! :D | |

Ravi's answer is a good one. I was hoping for a detailed but understandable description of the math behind it, but I think it is one of those things where the theory is so complex that it is above my understanding so I've just gotta accept the lay summary as fact. The older I get the more this becomes the case, lol!!
On the plus side though; bmin+240,820! Getting pretty close to that magical 250k that resets our guesses :D | |

Yeah I understand the reasoning now, however it still smacks of ....erm pessimism and if we all believed it were 100% correct, none of us would in fact, bother at all to search.
I think we all have a subconscious need to cross our fingers and hope for the lucky drop which we have proven exists by the finds PG has found.
No matter how unlikely it is to toss a coin 100 times and get all heads in a row, given enough time and attempts, it will happen at some stage.
I'm very glad I didn't follow this until now as I honestly wouldn't have bothered at all :) Haha
Edit: Highly unlikely does not equal impossible :D

I'm also glad you didn't follow this until now! Your presence here would be sorely missed!!
If you want a more optimistic way of looking at things, ignore the "progress" altogether and consider each task as a separate entity with a dice roll's chance of being prime. Eventually you'll get the number you're rolling for. This particular die is just a little bigger than average :) | |
