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

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 ).

100% correct, 🤗

182486

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 :)

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 still going to stick with +205,000 for my guess :)

Kellen + 205,000 Rob + 185,000 Renix1943 + 182,486

Anyone else?

:)

No sadly + 182,486 not prime but closest to wins so it has a chance still :)

Up to +176274 now. Hmmmn. Guess we'll have to wait n see :)

Up to +179174.

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 ;)

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 🙂👍

Haha, it's just going to slide right on past us all and that means Kellen will be the closest!!!

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.

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.

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 :)

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. :-)

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. :-)

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 :)

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 :)

Loved all the youtubers!! -)

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

I started a new thread for just general talking rather than keep hijacking this thread. :-)

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

415,000

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 :)

I threw a few droplets on this for the duration of the challenge just to keep things moving along.

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!

Ah no. "Several expletives" and several more..... and one more ... hrmph! 😡

Ok hands up. I ordered an i9 9900k laptop with a 2080 gpu. Hopefully will add to the party 👍

bmin+189888

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 :)

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!

Thanking you :)

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. 👍

bmin+193720

And Kellen is in play bmin+195726. 👍😉

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!

so how do you join this effort? GPU or cpo? Totally ignorant on this effort.

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.

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.):

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 :)

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