We have 34 files to be booked out to reach the end of September goal of getting to 3.45 million bits, in order to be on track for 3.6 million bits by the end of the year. join us!

A cursory inspection of (~7k) double checked 321 numbers revealed 1 unknown mismatch, but not prime :wink: I am still planning the script to scan for double checks...

Please keep up the good effort; We could find a mega-prime any day soon :unsure:

Thanks again to Xyzzy for uploading and hosting the new input files, which will take this project to 3.6 million bits. If we can do these by the end of 2007 that would be wonderful.

There will be about a further 100 files at the current FFT size; At 3.7 million bits I will reduce the input files to a range of 500, each containing about 29 candidates.

Although we expect the next 321 prime to be about 4 million bits, it could be found sooner. Give it a go -- you never know your luck! :wink:

We have reached 3.5 million bit candidate testing. Thanks to all participants for the help :tu: With more help, we could be the first "[URL="http://primes.utm.edu/bios/top20.php?type=project&by=ScoreNormal"]project[/URL]" to find a "[URL="http://primes.utm.edu/glossary/page.php?sort=Megaprime"]mega[/URL]-llr" prime. As a "[URL="http://primes.utm.edu/bios/top20.php?type=person&by=ScoreNorma"]person[/URL]" you could receive the credit. Join us, if you have not already.

Welcome PrimeGrid
 
We are proud to announce that PrimeGrid will be helping 321search from today.

This is how "credit" and "points" will be allocated:
[LIST=1][*]PrimeGrid will be treated as a "person" or individual with respect to [URL="http://www.mersenneforum.org/showthread.php?p=50474#post50474"]321's internal points system[/URL]
[*]If a "321 prime" is found by PrimeGrid credit will be shared between 321search and PrimeGrid at the Prime Pages database [I][URL="http://primes.utm.edu/bios/top20.php?type=project&by=ScoreNormal"]as teams[/URL][/I]
[*]If a 321 prime is found by anyone and PrimeGrid have reached at least 3rd position in 321's internal scoring system, then PrimeGrid will share Prime Pages points with 321search [I]as teams[/I].[/LIST]
Note that individual people who make a reservations on 321search's "[URL="http://www.mersenneforum.org/showthread.php?t=6808"]reservation system[/URL]" will get full credit for a prime as a "[URL="http://primes.utm.edu/bios/top20.php?type=person&by=ScoreNormal"]person[/URL]" at the Prime Pages; It has been left up to [URL="http://www.primegrid.com/"]PrimeGrid[/URL] as to how they share the Prime Pages points, if PrimeGrid finds a prime.

Cool! :cool: I already crunch for PrimeGrid, so when work is available for 321 I'll simply check the box in my preferences! (I was already hoping to do some 321 work on the one "core" [actually just a hyperthread] of my system that I reserve for non-BOINC stuff, but it's all booked out right now with other work, so this is especially great for me right now.)

BTW, is that why jmblazek reserved that humongous range yesterday? :wink:

paulunderwood 2007-11-19 16:15

It should be live already: [url]http://www.primegrid.com/apps.php[/url] :smile: but only Windows so far...

:lol: I am grateful to John for negotiating between Rytis and me over the PG-321 partnership.

It isn't shown on the home page in the box that lists how much work is available for each app, though...usually that means that it's still in testing. (But since the LLR app has already been developed there, it shouldn't be in testing long, I would think.)

I've already got it selected in my project preferences, though, so when it does go live I should get some work.

P.S.: Rytis said the estimated date is in 2 or 3 days:

Update: 321 work on PrimeGrid is now available.

[quote=Rytis (on PrimeGrid forums, link to thread is in my last post)]
Work should be flowing now. Validation is off for the moment, also no frontpage status update yet.

[quote=paulunderwood;96856][quote]IF you find a million digit prime soon (which I hope you do), will you still continue to LLR to 5 M? [/quote]Hardly, No. Personally, the main goal is a 1 million plus digit prime. The effort would have to be redoubled to find the following prime, most likely and that could be greater than 5M bits :cry: So it just a final push now. Help us :smile:[/quote]
I noticed this post up a ways in this thread...which prompted the question: If 321 finds a 1 million digit prime before they reach 5M, what is to be done with the rest of the sieve file? Is it going to be made available publicly in case another person or project wants to use the rest of it? Or, would all the sieving work from the point at which the project is stopped, up to 5M be wasted?

I'm thinking that even if the 321 project doesn't want to continue searching after they find a 1 million digit prime, it would be nice if maybe PrimeGrid still continued the search up to 5M--it would be a shame to waste all that sieving work. And since PrimeGrid is already planning to do tests that big in the future with their Cullen/Woodall prime searches, it's not like tests of that size will be bigger than they'd otherwise be doing.

paulunderwood 2007-11-28 21:15

I plan to hand over the remaining files to PrimeGrid, if and when we find the next prime. I have already discussed this John in emails between us.

PrimeGrid has two advantages. The first is they double-check results -- larger numbers are more error prone. The second advantage is people can just point their Linux and Windows boxes at the server -- Mac Intel too?
