The March to the Solstice

Come join the March to the Solstice (24 Nov - 19 Dec). We'll be pushing PPS (LLR) as far along as possible before the final Challenge of the year, the Winter Solstice Challenge (19 Dec - 22 Dec). We have established intermediate goals for PPS (LLR) and are within striking distance of completing them (excluding k=3) by the end of year 2011.

Proth Prime Search Update
k=3 to 25M is ongoing in the 321 Prime Search (currently at n=7505609)
k=5 to 5M (currently at n=3M)
k=7 to 4M (currently at n=3M)
k=9 to 3M (currently at n=3M)
10<k<32 to 2.5M (currently at n=2.5M)
32<k<100 to 2M (currently at n=2M)
100<k<500 to 1.5M ongoing (currently at n=1M)
500<k<1200 to 1.3M (currently at n=1.3M)
1200<k<4000 to 800K ongoing (currently at n=710k)
4000<k<10000 to 725K ongoing (currently at n=710k)

This by no means is a "walk in the park". :) It will take a concentrated and sustained effort to reach these goals. A by-product of this effort will be the most complete and organized proth prime collection in the world… hint: it already is but this just pushes the envelope once again. ;)

The final Challenge of 2011 is on the PPS (Sieve) application. The current range is from 3M<n<6M. n<3M was completed earlier this year…sieved to p=100P. We are now working our way through this range with primality testing (LLRing). This March to the Solstice will be a nice "segue" into the Challenge…exhausting one range while preparing for the next. :)

There are still plenty of primes to go around both in the 100<k<500 and 1200<k<4000 ranges. Also, we are still hoping for one or two high value primes in the k=5 & 7 ranges. To participate, simply check the Proth Prime Search (LLR) application in your PrimeGrid preferences.

Best of Luck to everyone!!! And have a Happy Holiday Season!

____________

Switching over 100% now, as soon as some other project WUs work their way through. Can't resist the chance of more top5000 primes :)

Hell i got two primes in the last two days!
Switched on another i5-2400 for ppsLLR to crunch away WUs until the start of the next challenge.

The March to the Solstice - UPDATE

We'll attempt to do regular updates to see how progress is advancing and how close we're coming to the end of year goal. Only remaining goals will be listed.

Hi girls and boys :)

Lets do a one week BOOST on PPS ....................


We have a goal so what are we waiting on ?


Lets crunch those 1M-1.5M fast now. :)

"A by-product of this effort will be the most complete and organized proth prime collection in the world…"

And where might a person find this complete and organized Proth prime collection?

Does anyone have a link?

• Proth Search
  
• Riesel and Proth Prime Database
  

A searchable/sortable prime list remains on PrimeGrid's wishlist. :)

Wow, looks like you guys used up all the glory...I can't get any WU's for the PPS(LLR)...I guess PPS(Sieve) will have to do until more WU is available...

I just installed Win 7 x64 to crunch PPS(LLR) with my two GTX460's, but alas. I'll do some protein folding while I wait.

I was under the impression that GPU LLR WU's aren't yet available via BOINC, despite the selection being available on the website.

My lucky number is 75898⁵²⁴²⁸⁸+1

Looking forward to seeing llrCUDA in production!

Not sure how often updates are planned, but it'd be nice to see them more often than not just to see how progress is going. Plus its good to see what we're on track of doing by the Solstice.

On the PRPnet ports I am crunching proths at n=290k. As PG is at a much highter n am I just rediscovering primes or does PG just start at a higher n range?

NOTE: It is impractical to put PPSElow work into BOINC due to the short testing times. The server has its hands full with the 10 minute PPS (Sieve) tasks and would probably crumble under the stress that 1 minute tasks would present. :)

Unless they were "bundled" with 20 or 25 tests together. ;)

The harder part is on the server side. It's not just the bundling and unbundling relating to serving the tasks to the clients that has to change. It's everything in the server that happens after that which will get complicated.

4000<k<10000 to 725K (currently at 725k)

The current active range is 100<k<500 to 1.5M.

NOTE: There are some active ranges in the 1.2M-1.5M range reserved at Proth Search. Therefore, at n=1.2M we will switch to 1200<k<4000 and take it to 750k. This will allow the Proth Search reservations more time to complete. We'll review the status again at 750k and go from there.

Are you able to share the current or recent probability of finding a PPS, John?

I am still at 0.0203% - that is 1:4926.
But with the current 6.11/6.12 app we would need longer to reach the goal since lots of WUs are trashed.

Thanks Roadrunner. That fits with my overall odds. I just wonder about the effect of bigger numbers and better sieving.

Actually it is been ages since I found a prime and I can't cope with the randomness of prime finding!

I found us another prime, 241, still (or back again?) at 0.0203%

The March to the Solstice - UPDATE

The march is going strong and we're making good progress. There's 14 days till the solstice and we look to possibly reach another goal...leaving the remaining three goals for after the Challenge. Therefore, now is no time to sit back and relax...there's plenty of work to do before then.

Please spread the word as more help is ALWAYS welcomed. Thank you and have a Happy Holiday Season!!! :)

I think i will skip the next challenge as i would stand no chance at the ppsSieve-challenge with my tiny count of GPUs. I will crunch ppsLLR until new years day in exchange with full throttle.

The March to the Solstice - UPDATE

There's 11 days till the solstice and progress has slowed a bit. However, a good amount of work is still being accomplished. One thing for certain, we need a lot more help if we wish to complete all of these goals by the end of the year.

The March to the Solstice - UPDATE

There's 8 days till the solstice. We still need a lot more help if we wish to complete all of these goals by the end of the year.

In preparation for the upcoming Winter Solstice Challenge, after 775k is reached with the current range, we'll be switching to k=5 & 7 from 3M to 4M. This should lower the stress on the server considerably.

FYI...in the next few hours, 1200<k<4000 will reach n=775k. We will enter the k=5,7 for 3M<n<4M range next. Expect testing times to jump considerably. This will reduce the server load quite a bit in preparation for the upcoming Winter Solstice Challenge.
____________

The March to the Solstice - UPDATE

There's 5 days till the solstice. We have entered into the k=5 & 7 from 3M to 4M range. Before there's any celebration about a new prime, one was sent out. 7*2^3015762+1 is prime and was found in 2008. Our apologies.

k=5 is a DC effort for the entire range and k=7 is DC to 3.7M. NOTE: The last prime found for k=5 was at n=1777515. It's been eerily primeless since then compared to the other k's<10.

Around 400 minutes on a Xeon W3520/i7-920...

The March to the Solstice - UPDATE

This must be some kind of record...we blew right through k=5,7 3M-4M and have now entered 4M-5M. A snafu in loading the next range allowed k=7 to also be included. Therefore, we'll be taking both k=5 & 7 to 5M. This will weaken our chances of finishing the goals by the end of the year.

We are doing our best to remain optimistic. The Winter Solstice Challenge is just a day away so we expect to see resources move there. However, we hope many of the CPU's stick around afterwards to do a final push to the end of the year.
