PPS (LLR) Milestones, Goals, and Progress

This thread will be a general continuation of this previous effort: Getting k < 1200 to n=1M before Challenge. We are attempting to fulfill our original intentions with the Proth Prime Search which are two-fold: 1) find primes for k < 10000; 2) push lower k's higher. The effort will now search lower k's to higher n's intermixed with the 1200<k<10000 range from 670K towards 700K. The current groups are as follows:

    k<10 to 3M (note k=3 is excluded since it's part of the 321 Prime Search)
    10<k<32 to 2.5M
    32<k<100 to 2M
    100<k<500 to 1.5M
    500<k<1200 to 1.3M
    1200<k<4000 to 800K
    4000<k<10000 to 700K

    Note: Lower k's provide better opportunities to find primes with (x)GFN divisibilities and even an elusive Fermat Number divisor.

We are also doing our best to balance both the SGS (LLR) and PPS (LLR) projects as they have a direct impact on each other in regards to the Top 5000 primes list. Please see this post for more details.

The current status is: The leading edge for PPS (LLR) k=5,7,9 has reached n=2.48M (that's 150k in the last 24 hours). Testing times now are ~4.9x's longer than they were at n=1M. They will continue to increase. There are 46k candidates remaining to reach 3M.

Regular updates will be posted to this thread.

Progress Update

The leading edge for PPS (LLR) has reached n=2.6M (that's 120k in the last 24 hours). Testing times now are ~5.2x's longer than they were at n=1M. They will continue to increase. There are 36k candidates remaining to reach 3M.

The first success in this extended effort: 9*2^1807574+1 (544135 digits - ranked 111th) found by Reuben Gathright (Reuben Gathright) of the SETI.USA team. A top 30 prime at PrimeGrid. :)

[EDIT] WOW!!! The second success quickly followed: 9*2^2543551+1 (765687 digits - ranked 57th) found by Scott Brown (Scott Brown) of the Duke University team. A top 20 prime at PrimeGrid. :)

Can we bump it back up to 200k/day to finish this off in the next couple of days? Afterwards, our first intermixing will occur as 1200<k<10000 for 670k<n<672k will be inserted.

Throwing 3 cores at the task (after trashing 24 WUs because I forgot to make the binaries executable after copying them into the project directory and modifying my app_info.xml). One core is reserved for the GPU.

Prime Fermat Divisor

Scott finds one of those "elusive" prime Fermat divisors. As hoped, searching the lower k's to higher n's has paid off. After further testing of Scott's k=9 prime, it was shown to divide F2543548. See news post for more info. Testing is complete:

    9*2^2543551+1 Divides F2543548
    9*2^2543551+1 Divides GF(2543549,3)
    9*2^2543551+1 Divides xGF(2543549,3,2)
    9*2^2543551+1 Divides xGF(2543549 ,4,3)
    9*2^2543551+1 Divides GF(2543549,6)
    9*2^2543551+1 Divides xGF(2543549 ,8,3)
    9*2^2543551+1 Divides xGF(2543542 ,9,2)
    9*2^2543551+1 Divides xGF(2543547 ,9,8)
    9*2^2543551+1 Divides GF(2543550,11)
    9*2^2543551+1 Divides xGF(2543550,11,2)
    9*2^2543551+1 Divides xGF(2543550,11,3)
    9*2^2543551+1 Divides xGF(2543550,11,4)
    9*2^2543551+1 Divides xGF(2543550,11,6)
    9*2^2543551+1 Divides xGF(2543550,11,8)
    9*2^2543551+1 Divides xGF(2543550,11,9)
    9*2^2543551+1 Divides GF(2543549 ,12)
    9*2^2543551+1 Divides xGF(2543550,12,11)

This is not only a success for Scott but for everyone else participating as well. Congratulations to you all!!!

    ? will be updated once testing is complete.

This is not only a success for Scott but for everyone else participating as well. Congratulations to you all!!!



I am somewhat aware of what Fermat numbers are, but what do the notations GF(a,b) and xGF(a,b,c) mean?

GF(a,b) is the Generalized Fermat number b^2^a + 1.
xGF(a,b,c) is the extended Generalized Fermat number b^2^a + c^2^a.

Progress Update

The leading edge for PPS (LLR) has reached n=2.75M (that's 150k in the last 24 hours). Testing times now are ~8.1x's longer than they were at n=1M. They will continue to increase. There are 22k candidates remaining to reach 3M.

A lot can happen in 24 hours. Two primes and a World Record Prime Fermat divisor. Congratulations to everyone for this success. While we didn't bump it back up to 200k/day, 150k/day is quite respectable considering testing times continue to increase.

Note: Next range will be 1200<k<10000 for 670k<n<672k.

[EDIT] WOW!!! The second success quickly followed: 9*2^2543551+1 (765687 digits - ranked 57th) found by Scott Brown (Scott Brown) of the Duke University team. A top 20 prime at PrimeGrid. :)

Congrats Scott.

At http://www.prothsearch.com/fermat.html, I noticed that a Fermat divisor was found on March 12th within PrimeGrid: 7333 · 2^138560 + 1 divides F138557.

What's the story behind this discovery? Was a mistake made back in March?

In short, it was discovered on 12 March 2011 but was not realized until a double check effort of all Proth primes n<210k revealed it had been overlooked. Please see news post for more info.

Progress Update

The leading edge for PPS (LLR) has reached n=2.99M (that's 240k in the last 48 hours). Testing times now are ~8.2x's longer than they were at n=1M. They will continue to increase. There are 1.7k candidates remaining to reach 3M.

We'll complete the last of the 3M work today and enter the next range of 1200<k<10000 for 670k<n<672k. There are 262k WU's in this range.

Thanks for all the help as we begin this new phase of the search. We'll return to low k work (10<k<100 for 1M<n<1.5M) probably in a few weeks.

[EDIT] As of this edit, new work is now going out.

I did the same thing Honza. I may set my grid back to PPS though if the PSPs aren't gonna run well on my older chips. If the PPS runtimes increase too, I suppose credits will as well? As I recall, PPS never game a ton of credits but it's got a great chance of finding (or in this case, rediscovering) primes.

Progress Update

All work for k=5,7,9 up to n=3M is out. Current work is being drawn from the 1200<k<10000 for 670k<n<672k range so testing times have returned to "normal". We'll use n=1M as the base testing time. These WU's are almost 2x's faster than tests at n=1M. Depending on completion rates, n may be increased to n=675k.

Thanks for all the help as we begin this new phase of the search. We'll return to low k work (10<k<100 for 1M<n<1.5M) once the current range is out.

FYI, k<1200 for n<1M is complete. This is a major accomplishment! Congratulations everyone!!!

Progress Update

All work is out for 1200<k<10000 for 670k<n<675k range. Yes, the range went quickly so it was increased to 675k.

We have returned to low k work (10<k<100 for 1M<n<1.5M). Testing times are back up to the 1M baseline. In fact, we are already at 1.14M so times are about 1.3x's that at 1M. These will continue to increase as n increases.

A lot of the work up to 1.2M will be double check work from previous efforts. A bit more first pass will open up from 1.2M-1.4M. Afterwards, over half the range will be first pass.

Thanks again for all your help and support.

Progress Update

k=5, 7, 9 for 1M<n<3M is COMPLETE!
1200<k<10000 for 670k<n<675k is COMPLETE!

EXCELLENT work!!! Well done everyone.

10<k<100 for 1M<n<2M is the current range. Progress now is at n=1375289. Testing times are about 1.8x's that at 1M. These will continue to increase as n increases.

Our double check work is getting less and less as you can see here:

    31% first pass at 1.2M
    44% first pass at 1.3M
    62% first pass at 1.4M
    69% first pass at 1.5M
    78% first pass at 1.6M
    87% first pass at 1.8M
    91% first pass at 2.0M
    96% first pass at 2.5M

At n=2M, we'll pause again and complete a PPSE range of 1200<k<10000 for 675k<n<680k or 685k. Afterwards, we are looking at 10<k<32 to n=2.5M.

Thanks again for all your help and support.

Is the plan still to work on 1200<k<10000 afterwards..?

PPS and SGS (and I think one other) have adaptive handout. If your machine proves itself for a set amount of period it can be considered good enough to do work without a wingperson. It will get dual jobs and most of the time you will be the second receiver to a person who's not been deemed good enough to work on their own.

Enjoy the pleasures of getting work that is immediately validated.

No, SGS (LLR), PPS (LLR), and TRP (LLR) use Adaptive replication. That's why sometimes you see a minimum quorum of 1.

I *think* that any WU where the result is a prime is double-checked, even if the initial replication is 1.

I guess the question is more to do with if there is double-checking eventually for the candidates where adaptive replication only sent out one WU and it was reported as composite. There could be missing primes in there. If you're just looking for top 5000 primes, it doesn't matter too much per se, but it does mean that recording the limits of the search are more complex. It does matter a lot more for conjecture proving, and also as n increases the error rates get higher.

I guess the question is more to do with if there is double-checking eventually for the candidates where adaptive replication only sent out one WU and it was reported as composite.

This was my question.

Hi all crunchers :)

We only have ~13k numbers left on PPS (n=1M-2M) so all help is needed to finish them.

If you can ? please switch to PPS LLR to get all wu's out there done.

I will raise buffer on frontpage to 10k That way you can see progress.

When it get close to zero I will load PPS n= 675k-680k.

Why ? We have a challenge soon :) We need to try to get all 1M-2M done
before the challenge


Thanks

First we will do n=675k-680k (maybe higher)


After that we follow the plan k= 100-500 up to n=1.5M

I'm pretty new to this whole thing. Will the crunching times go up with the increase in k, or is the amount of actual work done in a WU the same? (that should show my ignorance of the math behind it)...

Just trying to figure out if it is the size of "n" or the size of "k" which has the most impact on crunching times...

Thx

Edit: I said "size" when I really meant "k"

It is the size of n that increase time. There is a little increase when k's get bigger but nothing you will notice here on pps.

The range we will start now (675k-680k) is much faster then those we are running now ( n=1M-2M)

Edit: I said "size" when I really meant "k"

Short answer: just the n. The k's effect is essentially negligible.

Long answer:

It's mostly the n that makes the difference in crunching time. Think of it this way: if you have two sequences of numbers, like this:

1*2=2; 2*2=4; 3*2=6; 4*2=8; 5*2=10
versus
2^1=2; 2^2=4; 2^3=8; 2^4=16; 2^5=32

the latter increases in size much more quickly, being an exponential sequence instead of a linear one. The numbers being tested in the Proth Prime Search are defined by the sequence k*2^n+1. Since n is an exponent and k merely a multiplier, the n will have a much greater effect on the size of the number, particularly as we generalize this to large values of k and n. The k does still have an effect, but it is minuscule compared to that of the n. And since crunching time is proportional to the size of the number (read: number of digits), it is by extension affected primarily by the n.

Even longer answer (continuing from the long answer): :-)

Note that the k does have a secondary effect which can make a more significant difference in crunching time. For calculations of this type, the most efficient way to run them on a computer is to use what's called a Fast Fourier Transform (FFT). The full details of such an algorithm are, needless to say, very complicated, but the part relevant to this discussion is that computers are programmed to handle FFTs in such a way that their sizes increase in a stepwise manner. It's somewhat like gears in a car with a manual transmission, where (for instance) first gear is good for everything up to 15 MPH, second gear up to 20-25 MPH, third gear up to 35-40 MPH, and so on. You can drive at 40 MPH in first gear, but you'll waste a lot of gas and probably ruin your engine; the reverse, however, is not true, for you'll stall the car if you drive at 10 MPH in third gear. With FFTs, you can safely use too big an FFT (at the expense of additional crunching time), but using too small an FFT will produce an inaccurate result. The trick is to find the lowest FFT that you can use safely. The LLR code at the core of PrimeGrid's worker application does this automatically, and makes its decision by looking at the k and n and comparing them with a hardcoded table of what's safe to run with what FFT. So the k does have some effect on the crunching time, though still not so great an effect as the n; and the difference still evens out to an exponential progression as n increases with k held constant. For this reason, the lowest k's are considered the most desirable, because you can find primes of the same size with less work. That said, the difference isn't huge until the size of k increases greatly (for instance, k=500 will not take much longer to test than k=10, but k=100000 will take noticeably longer).

Hope this helps! :-)

Actually both answers were helpful. Thanks to you both! My trade is as a systems administrator and starter programmer, not as a scientist (or mathematician more accurately). Wikipedia is woefully full of too much information on primes in general to grasp in one go (and generally terrible at describing the different search algos from a computing perspective) :)

Any suggestions on what sub-project could benefit most from an additional 336 2.6Ghz Nehalem cores crunching on them (That's sort of tongue in cheek since I'm posting to the PPS LLR status thread)? I've got an (actual) small server farm to burn-in which comes online within the next couple of weeks if I do my job right :p . Most of the project status posts (and the preferences pages) seem to be out of date.

The good news, is that the administration of the server farm is under my control (including whether or not it runs primegrid after business hours :D).

Thanks

First we will do n=675k-680k (maybe higher)


After that we follow the plan k= 100-500 up to n=1.5M

Lennart

We're already at 680K, so John's suggested 685K looks
likely if we're going to have any of these left for the Challenge?

I've been running TRP LLR's on the 32-bit blade cluster
(looking for "gold"), but am planning on finishing those
before/during the Challenge, to get mostly PPS LLR's.

I though that you were referring to n=680k-685k (which
John had previously mentioned), but I'm seeing valid tasks
from 682k already. Any chance "maybe higher" might stretch
to 690k?

Nothing wrong with some portion of the contest running in
"k= 100-500 up to n=1.5M", but I can certainly confirm that
these n < 700k are giving a lot more hits (of the type appealing
to people dropping in for the contest) than the larger n's we
were running just before. -Bruce*

Hi all PPS freak :)

We did load all up to 700k.


After 700k ther are 2-3 options. We will decide after the challenge what will come after 700k.


Happy crunching...

Apparently the decision was already made as I see tasks for n>700000 going out for k>1200. What was that decision?

This doesn't sound like the previously mentioned

"After that we follow the plan k= 100-500 up to n=1.5M"

looks more like

Thanks; so I can stop counting 9's to find when the next range
starts arriving. That's n=690xxx, n=6990xx, n=69990x that I've
been seeing in my valid task list, PPS LLR. -Bruce

I was looking for an explanation why my PPS LLR units suddenly increase from a 9 minute runtime to 80 minutes runtime.
I guess this has something to do with it?

Yes and no. Yes it is because of the larger n's, but not the ones mentioned here if I'm not mistaken. I guess you're getting pps_llr instead of pps_llr_extended, like me and some of other power cows on our own forum? If you look at the results you'll see that _extended is with n's in the range of 700k - 7??k, but the non extended are for n's over 2M. This apparently costs a lot more time.

Credit is not the most important for me on LLR, I am more interested in finding primes, so just wanted to know what the impact is of these longer WU's for finding a prime.
If the chance prime/not prime stays the same, then the chance of finding a prime has decreased (ie. 9 times smaller).

TheDawgz are frequently fuzzy on these type of things so please correct us if we are wrong ... but
It looks like we have moved into a range that John had mentioned back in July consisting of low k's and n's > 2M.
If so, then this should be mostly 1st pass work and the primes should make the Top 100 with digit counts >600k.

Looks like a mixture of ranges on my end. I've got wu's running between 15 minutes and 1:30 hours on the same machine. So, here's hoping to find one of the "big" primes.

Message 40085 - Posted: 7 Sep 2011 | 17:32:24 UTC - in response to Message 40063.

I was looking for an explanation why my PPS LLR units suddenly increase from a 9 minute runtime to 80 minutes runtime.
I guess this has something to do with it?

Our apologies. The tasks were from our next range: 10<k<32 from 2M<n<2.5M The work was uploaded yesterday and the WU generator started sending them out prematurely. There's still ~100k tasks remaining in the 709k-710k range. The issue has been resolved and the work has returned to that range.

Here's an update to the remaining PPS ranges on the todo list:
    10<k<32 from 2M<n<2.5M
    100<k<500 from 1M<n<1.5M
    500<k<1200 from 1M<n<1.3M
    1200<k<4000 from 710k<n<800k


Additionally, we are looking at splitting out the single digit k's to achieve the following levels:

    3 @ 7M (321 Prime Search - ongoing effort)
    5 @ 5M
    7 @ 4M
    9 @ 3M (already at 3M)


So basically, it's only 5 & 7 that would increase. Our effort remains to search lower k's to higher n's intermixed with work from the 1200<k<10000 lower n ranges.

As I maintain prothsearch.com, I recommend taking 5, 7, and 9 to 5M.

Just because you add or subtract 1 from a given number, you do not necessarily end up with a prime number.

But in my guess it could be either even or odd.

If they are even, they should not be prime numbers.

What about this example number: 8867383 .

Put that number into a formula and try deduce whether it is prime or not.

Anyway, I just put it together a little bit and wrote 37*49*67*73 into my calculator.

Only 49 (7*7) is not a prime, the other three numbers are.

So, if a given number happens to possibly return a factor in it, that number is not prime, but what about any number in it (like 73)? They could be prime numbers on their own.

The fundamental theorem of arithmetic says that every integer greater than one can be written as a unique product (up to ordering) of primes. So the prime factorization of the number you gave is 7*7*37*67*73.

Yes. 10<k<32 from 2M<n<2.5M is now in the queue. It will be followed by 500<k<1200 from 1M<n<1.3M and then an n range in 1200<k<4000 from 710k<n<800k.

[...].


The number they add or subtract 1 to/from is always even, because it is a multiple of 2. Therefor every number tested must be odd, exactly because every even number other than 2 can not be prime.

Yes. 10<k<32 from 2M<n<2.5M is now in the queue. It will be followed by 500<k<1200 from 1M<n<1.3M and then an n range in 1200<k<4000 from 710k<n<800k.


Great, thanks for the update.

Progress Update

Progress through the 10<k<32 for 2M<n<2.5M range has been surprisingly quick. We are currently at 2.375M after only a couple of days. At this rate, we should reach 2.5M in 3-4 days. That is quite IMPRESSIVE!!!

Next up is the 500<k<1200 for 1M<n<1.3M range. We are skipping over the 100<k<500 for 1M<n<1.5M range (for now) to give participants at the Proth Search Site time to complete their reservations. Afterwards, we'll complete a section of the 1200<k<4000 to 800K range.

Proth Prime Search Update
k=3 to 25M is ongoing in the 321 Prime Search (currently at n=7457987)
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 is ongoing (currently at n=2004074)
32<k<100 to 2M (currently at n=2M)
100<k<500 to 1.5M (currently at n=1M)
500<k<1200 to 1.3M (currently at n=1M)
1200<k<4000 to 800K is ongoing (currently at n=691891)
4000<k<10000 to 700K is ongoing (currently at n=691891)

Progress Update

Faster than expected, work for the 10<k<32 for 2M<n<2.5M range has been emptied. We are now in the 500<k<1200 for 1M<n<1.3M range. Next up we'll complete a section of the 1200<k<4000 to 800K range...most likely 710k-725k, more if necessary.

Hi all,

I have some questions concerning PPS:

When i look at the range statistics page, I wonder why there are only 1186 tasks completed for k=4801 when 21210 are done for k=4785 ?

On the 5, 000 largest known prime list, I read for instance that 27*2^2218064+1 is prime and it was found in 2009, but it is in the n=2-2.5M range we just finished to check. So, my first question is what project found this prime in 2009 ? The second is how do you take this former discovery into account ?

I found mentioned prime on PRPNET (27121 Prime Search subproject: k=27 & 121 for k*2^n+-1 for n<10M)

This particular range of k=27 (now n~3,77M) was already covered, same apply for k=121 (now n~4.39M)

When i look at the range statistics page, I wonder why there are only 1186 tasks completed for k=4801 when 21210 are done for k=4785 ?

The k's have different densities. After sieving, k's have a different number of candidates remaining. In this case, k=4785 has a great deal more candidates remaining than k=4801.

Nash weights are typically used to compare remaining candidate densities between k's. Chris Nash created the Nash Sieve. From this, in collaboration with Paul Jobling, came psieve. psieve offered an option that would calculate the Nash weight of k's. This is simply the count of those n remaining after applying the Nash sieve. The standard Nash weight is calculated over the range 100000 < n < 110000.

Another comparison tool is Jack Brennen's Proth Weight applet. If you input 4785 to 4801 with step 2, you'll see for that range that k=4785 is the highest weight and 4801 is the lowest weight.

Note that these are general comparison tools.

On the 5, 000 largest known prime list, I read for instance that 27*2^2218064+1 is prime and it was found in 2009, but it is in the n=2-2.5M range we just finished to check. So, my first question is what project found this prime in 2009 ? The second is how do you take this former discovery into account ?

As Honza points out, 27*2^2218064+1 was found in a previous PrimeGrid effort in PRPNet. When new work is loaded, we mark all known primes so they are not tested again.

Additionally, there are individual searchers who are prime finding on their own. We invite all individual searchers to upload their residues to save PrimeGrid time in (double) checking their ranges.

Most of the time. There are those few that sneak through every so often. Take it from someone who had one :-)

Progress Update

Progress through the 500<k<1200 for 1M<n<1.3M range has been trudging along. Today we have reached n=1.1M. At that rate, we have AT LEAST 24 more days to reach 1.3M.

Next up is the 1200<k<4000 to 800K range (710k-725k). It is probably while we're in this range that we'll see the end to SGS single primes making it into the Top 5000 list. :(

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 (currently at n=1M)
500<k<1200 to 1.3M is ongoing (currently at n=1.1M)
1200<k<4000 to 800K (currently at n=710k)
4000<k<10000 to 700K (currently at n=710k)

FYI, as of this post, n entry levels in the Top 5000 list:

350th - n=1338620
400th - n=1269198
500th - n=1168975
600th - n=1086798

The leading edge is now at n=1280000 close to the 1,3M edge.
If the suspension of PPS prime reporting continues, may I suggest PPS continues at k=5 (and/or 7) instead of 1200<k<4000 since there are fewer primes in the higher n range (lower k)...

The leading edge is now at n=1296000, hours away from the 1,3M cut.
Since the PPS prime reporting halt is still ongoing, i'd like to re-visit my suggestion below to continue with lower k's (5 and/or 7) instead of 1200<k<4000....
Any thoughts/comments...?

...
Here's an update to the remaining PPS ranges on the todo list:
    10<k<32 from 2M<n<2.5M
    100<k<500 from 1M<n<1.5M
    500<k<1200 from 1M<n<1.3M
    1200<k<4000 from 710k<n<800k


Additionally, we are looking at splitting out the single digit k's to achieve the following levels:

    3 @ 7M (321 Prime Search - ongoing effort)
    5 @ 5M
    7 @ 4M
    9 @ 3M (already at 3M)


So basically, it's only 5 & 7 that would increase. Our effort remains to search lower k's to higher n's intermixed with work from the 1200<k<10000 lower n ranges.


Alternatively, if 5 & 7 were split out, people could switch from PPS LLR to the
5-split or 7-split projects. I might run some of each; keeping an eye on the top20
list (by number, not by score! tied at twelve, but with enough backlog for 11th).

Meanwhile, the return of electric here has produced a SGS hit; my first since April 14.

The queue is filled again --- not sure what with, but something. One
of my managers was reporting no tasks for c. 5 hours. -Bruce*

(Two SGS hits ... These don't seem to be getting reported either;
nothing from PrimeGrid in the past 48 hours --- only one,

Yes, looks like
3061*2^710016+1 is not prime.

Given that not even SGS primes are being reported, looks like
our Admins are busy elsewhere. If one compares SGS and the
present PPS LLR range, n = 710000 is going to be well above
the lower edge of the Top5000, for a while, at least.

Alternatively, if 5 & 7 were split out, people could switch from PPS LLR to the
5-split or 7-split projects.

I apologize for the miscommunication. I should have said "singled out within the PPS (LLR) project" instead of splitting out. k=5 & 7 will remain within the PPS (LLR) project. There are currently no plans on separating them out like k=3 which btw was a collaboration with the 321 Search project. :)

But the PPS-reporting-halt is a mess

Yes, the lack of prime submissions external to PrimeGrid has caught us by surprise...meaning that PPS primes will have to wait a little bit longer before submission is resumed. However we view this as a positive as it allows more users searching SGS to submit their primes into the Top 5000 list.

PPS prime submission will continue to be suspended until SGS falls out of the Top 5000 list. The bottom 50 can be viewed here. Current PPS primes awaiting to be submitted will enter at position ~330th to 690th. Their expected lifespan in the Top 5000 list is upwards of a decade. Therefore, there's no concern of them falling out any time soon.

The 710k-725k primes will enter at position ~3260th. Again, no concern of falling out any time soon.

Thank you for your patience as we navigate through SGS's end to the Top 5000 list.

...meaning that PPS primes will have to wait a little bit longer before submission is resumed. However we view this as a positive as it allows more users searching SGS to submit their primes into the Top 5000 list.



Might I suggest that at this point, all that is being accomplished is delaying the inevitable, at the cost of artificially withholding submissions that by all rights aught to have already been submitted.

Although I consider it unlikely, it is conceivable that someone other than PrimeGrid might also submit the prime to the top 5k list. I don't think you want to be in the position of defending the non-submission to the prime finder if someone jumps ahead of him/her and submits it manually while the primes are being withheld.

My opinion, for what it's worth, is that more harm than good is being done right now.

I think the idea is that no one will do SGS if they do not get into the top 5000.

I think it is rubbish, consider that many happily do Sieves and SOB with no chance of finding a prime (SOB = very little chance with only 5 left to find and 17 for the whole project).

I agree that admins should let nature take its course. I have no personal gain in ths as I have not got any primes (not even waiting ones).

No, that is not the case. It's simply to optimize the end of SGS on the Top 5000 list. BTW, TPS continued quite well after it fell from the Top 5000 list and eventually, the twin was found.

That would be the pair with n = 333333, 8/13/2009. Sounds like
n = 333333 fell off of the top5000 in 2009, with n = 666666 falling
off in 2011. Would a plausible extrapolation be that n = 999999
will fall off some time in 2013? If so, n < 1M lasts only two years.

That's a longer time-frame than the next couple of weeks, to one
month, maybe for PPS LLR reporting to be unfrozen. My first result
in distributed computing was c. 1/3 of the sieving for breaking RSA-120
in June 1993. I'm starting to wonder whether the next two years
of PPS LLR might merit a higher priority than weeks 3 and 4 of keeping
SGS in the top5000; which would suggest a hard deadline of
Nov 21. My current backlog of 20 hits (18 PPS, 2 SGS) is a moderate
career's-worth. My most recent was 10/14; next week will be a month's
worth of computing with no feedback on results. Just wondering ...

We are well into 1200<k<4000 to 800K range (710k-725k). SGS has officially dropped out of the Top 5000 list and the backlog of PPS primes have been submitted.

Next up is the 100<k<500 to 1.5M range. We expect to enter that range within the next two weeks.

...

Looks like these are starting early, n=1M, before the finish to 725k --- likely
to keep traffic down for the duration of the Challenge?

I'm still seeing a mixture of the two, but the earlier range is still in
n = 722k, so perhaps the two weeks worth is being deferred.

Looking to get my gold on 321 during or soon after the Challenge,
then maybe work on TRP. -Bruce*

It's the nature of the WU generator. When both PPS (4<k<1200) and PPSE (1200<k<10000) work is in the queue, both will go out together. Otherwise, it's typically by n.

At the rate PPSE (1200<k<10000 for 710k<n<725k) was going out, we were going to be empty in a day or two.

Here is a milestone of sorts -- My first prime I got since coming back to PG in July 2011 is now ranked 5035 -- It entered the top 5000 ranked 3513 in August 2011

5035 --- 2337 · 2^678383 + 1 -- 204218 -- L2522 -- Aug 2011

Progress Update

The March to the Solstice has made good progress towards accomplishing these goals.

NOTE: 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.

2012 Goals - Progress update

The 4000<k<10000 range has made some GREAT strides over the past week going from n=725k to n~747k. That's pretty AMAZING!!! And just as expected, producing a lot of primes for the Tour. BTW, the effort to get to 1.5M resulted in completing the first goal of 2012. Congratulations to all!

Thank you to everyone for participating. Should we reach n=775k next week, the 1200<k<4000 range will be added and both will be loaded up to n=800k. That should definitely last through the end of the Tour.

Would you consider testing all of these (or just 5 and 7) to the same n?

Will there ever be an expansion above k=10,000?

I like seeing discoveries of Fermat divisors, and there are probably some low n primes in the 10000<k<50000 range.

Top 5 Fermat factors with k>10000:

71007 * 2^49490 + 1
177795 * 2^38969 + 1
121531 * 2^30260 + 1
13323 * 2^19220 + 1
17217 * 2^14530 + 1

Those are some pretty low n values!

Perhaps a separate project dedicated to high k value Fermat divisors would be more appropriate though. I doubt we'd find many top 5000 primes, if any.

Will there ever be an expansion above k=10,000?

I like seeing discoveries of Fermat divisors, and there are probably some low n primes in the 10000<k<50000 range.


There is already a project that has a search, although it isn't coordinated with a client/server app. Go over to fermatsearch.org.

As rogue mentions, F E R M A T S E A R C H . O R G offers what you're looking for. Additionally, in their news section, you'll see PG's last two Fermat primes. :)

Also, if you take a look at Prime factors k · 2^n + 1 of Fermat numbers F(m) and complete factoring status compiled by Wilfrid Keller, you see at the bottom of the page Known search limits. In the 10000<k<50000 range you mention, here are the following limits:

up to k=10000 has been searched to n=210000 (actually, latest PRPNet progress shows n=313065)
up to k=20000 has been searched to n=77000
up to k=50000 has been searched to n=61000

k=5 to 7M - (currently at n=5M)
k=7 to 6M - (currently at n=5M)
k=9 to 4M - (currently at n=3M)

Would you consider testing all of these (or just 5 and 7) to the same n?

Once all the goals have been met for the year, this would certainly be considered. Note that k=5 is such a low weight that getting it to 7M would only take a week or so. However, k=7 & 9 are heavy weights and would take quite a bit longer. Even just getting k=9 to 5M will take some time.

What's the plan after n=800k has been reached for the current range? Will the next range of n's be loaded for 1200<k<10000 or will we be switching back to lower k's/higher n's?

500<k<1200 to 1.5M - (currently at n=1.5M)
1200<k<4000 to 1.25M - (currently at n=775k)
4000<k<10000 to 1M - ongoing (trailing edge n=728077; leading edge n=746811)

2012 Goals - Progress update

The Tour de Primes has really done a nice job advancing PPS (LLR) towards its 2012 goals. Well done everyone!!!

Work will continue for the 1200-10000 ranges up to n=800k. Afterwards, a decision will be made where to go next. Most likely the search will stay at this level and push towards n=850k or even 900k. It all depends on progress. The past 3 weeks have just been incredible moving through a 55k n range. If the pace continued, 850k could be reached by the end of March.

As for other ranges, there's definitely plenty of work to do. The path forward will be to "cherry pick" some of the easier goals to achieve. It's nice to see bold green in the list. ;) Expect a pattern of venturing off to another range and then back to 1200-10000. This will be repeated over and over for the rest of the year.

Thank you again to everyone helping out with this effort. :)

We are now at 799k territory.
Since now further annoucement was made, I assume we will simply continue in most likely scenario.

I wonder when it gets increased?

Work will continue for the 1200-10000 ranges up to n=800k. Afterwards, a decision will be made where to go next. Most likely the search will stay at this level and push towards n=850k or even 900k.

We are now at 799k territory.
Since now further annoucement was made, I assume we will simply continue in most likely scenario.

FFT length: 64K
I wonder when it gets increased?


Hi

800k-810k is loaded and I think we will go to at least 900k first and then we can discuss further directions.

All I ask is that Primegrid hold off on k=63 & k=87. I have been independently crunching those k values for n>2,000,000. Once I'm finished, I'll gladly share the results.

I have been crunching these two k values, even at lower n, for quite some time.

(edit): Please hold off on "32<k<100 to 2.5M - (currently at n=2M)"
____________
15547296^32768 + 1 is prime!
63 · 2^1356980 + 1 is prime!
63 · 2^1356980 + 1 divides xGF(1356973,11,4)!

You can check the progress here also: http://www.primegrid.com/stats_pps_llr.php

It looks like we are sitting at 856K complete for the 1200<k<4000 and 4000<k<10000 ranges. So we completed about 100,000 n for each k in the last two months. I think we can definitely accomplish these goals by the end of the year if we keep making that kind of progress.

I was mentioning passing Buster for 7th over on the credit milestone
thread; but perhaps it's worth noting that credit here on PPS (LLR) is
pretty good. I blew past both Buster and Mumps (who hasn't been
moving) into 6th --- my RAC took a dip while running some TRPs during
the Challenge, but it's gone back up after switching back.

With a clear field up to 870k in view (and perhaps somewhat further
after that, towards 900k), I starting to contemplate the nearly unthinkable.
Another 1000 points to catch Lennart!

Actually, I like this stats. It is a long way run and doesn't involve GPUs...yet.

I hope to get 10th (by score) soon. 5th by total prime count...it will not last long, will it?

7821*2^889737+1 is not prime. 2447*2^889707+1 is not prime. 6041*2^889705+1 is not prime.

The options appear to be to staying with these k = 1200,4000;
k = 4000,10000 perhaps heading towards n=1M or switching
to one of the smaller k ranges. Judging by the above we may
know soon what Lennart et.al. have decided.

(Well, fairly close.)

Currently 3rd on the PrimePages Top20 by number of primes;
two behind Broadhurst for 2nd (actually 1+ epsilon).

Edit to my previous post, I thought we had transitioned ranges because my computer was now taking 7+ hours to do a PPS LLR, but it turns out some WU I had aborted didn't end their processes and were hogging up all my CPU resources. D'oh.

I am working on a new SGS range now so We will go up to 1M before we start on lower pps k's.

2012 Goals - Progress update

Good progress is being made in advancing PPS (LLR) towards its 2012 goals. Let's keep up the good work!!!

Work will continue for the 1200-10000 ranges up to n=1M. SGS is actively being sieved and we want to make sure PPS is high enough to remain on the Top 5000 when SGS starts.

After n=1M has been reached for 1200-10000, the path forward will be to "cherry pick" some of the easier goals to achieve. It's nice to see bold green in the list. ;) We will then return to 1200-4000 to push it to n=1.25M.

Thank you again to everyone helping out with this effort. :)

Proth Prime Search Update
k=3 to 9M - ongoing in the 321 Prime Search (trailing edge n=8374043; leading edge n=8399706)
k=5 to 7M - (currently at n=5M)
k=7 to 6M - (currently at n=5M)
k=9 to 4M - (currently at n=3M)
10<k<32 to 3M - (currently at n=2.5M)
32<k<100 to 2.5M - (currently at n=2M)
100<k<500 to 2M - (currently at n=1.5M)
500<k<1200 to 1.5M - (currently at n=1.5M)
1200<k<4000 to 1.25M - ongoing (trailing edge n=881184; leading edge n=891369)
4000<k<10000 to 1M - ongoing (trailing edge n=881974; leading edge n=891369)

Green represents a completed goal.

Some of the SGS timings appeared focused on n=1.29M with large k.
Is that the range of the new SGS/twin llr search? In a few years that
would bump all of 4000 < k < 10000 for sure, looks like all of
1200 < k < 4000 as well. Of course, all primes below 1000000-digits
will be bumped from the top5K eventually, presuming that we keep at this,
and a SGS search that far above 2^1M will find primes at a slower
rate than we're enjoying here below 2^1M.

To re-phrase the question, with the previous SGS search at
200700-digits, what's the new threshold? Looks like n=1.29M
suggests somewhere above 370000-digits, perhaps a round
400000-digits?

Best Regards, Bruce*

(currently 2nd on the PrimePages list by number of primes
on the top5K list)

Does the first range being done mean that SGS will start again, or will you go further into the sieve before the project is started again? And what n level is it this time?

Leading edge is almost ~915k and FFT size of 72K is stating to kick in with higher k's.
Expect some WUs with longer processing time of ~20%.

The pace slowed, it looks like we won't hit 1mil until late September/possibly early October, regardless, we should finish off <1mil before the challenge which will mean we should be able to destroy the next range during the challenge (I'm guessing that will be the 1200<k<4000 range to 1.25mil goal that we will work on during the challenge since they would have the shortest times of the remaining goals. Although Lennart did say:

After n=1M has been reached for 1200-10000, the path forward will be to "cherry pick" some of the easier goals to achieve. It's nice to see bold green in the list. ;) We will then return to 1200-4000 to push it to n=1.25M.
Perhaps we will finally have a PPS challenge that won't challenge the servers?

mean ...


Here's another week's progress (of a sort)
Added 109143 : 9071*2^983279+1 (296001 digits)


296K-digits, with another c. 17K bits left to go to k=1M.

-bdodson*

(rapidly dropping from 200 primes on the top5000,
down to 180 primes; and down from 2nd to 4th
place by number of primes)

(255K-digit Proth primes from April/May 2011 - April/May 2012
dropping out of the top5000 more quickly than I'm
finding new 296K-digit primes ...)

I asked Lennart about this when posting the challenge announcement. This was his answer:

We have to finish all up to 1M first so we might load 1M+ if we need more in the challenge and change to lower k's after the challenge. If we finish 1M before the challenge we might start on a lower k.


Seeing how we have a challenge that will only last 1 day I would think it's most interesting to load 1200<k<4000 to 1.25M is most interesting, as this will allow most people to participate.

I agree with you. I also don't think it will take too terribly long to finish off that range.

Good News Everyone! Leading edge is over 1M. But why 4000<k<10000 is also loaded over 1M? I thought we'll focus on 1200<k<4000 after we reach 1M.

I'm guessing code on the server needs to be updated in order for a new range to be sent out.

Lennart's June 2012 Update gives 1M as the target for the year
on 4000 < k < 10000. Of the recent Proth's above 1M, three have
k < 4000 (mine's 3791*2^1001609+1 (301518 digits)), while there
are fourteen with 4000 < k < 10000. (That's relative to the Prime
Pages window of 72 hours.)

Seems like a majority of our current effort is focused off of the annual
targets, which includes 1200 < k < 4000 to 1.25M. There's also the
usual odds for a Proth prime to be a Fermat divisor of 1/k, which favors
k < 4000; although searching k > 4000 gets credit (on the 'Pages)
for larger difficulty.

The leading edge is the same for 1200<k<4000 and 4000<k<10000, they aren't favoring either.

2012 Goals - Progress update

Good progress is being made in advancing PPS (LLR) towards its 2012 goals. Let's keep up the good work!!!

Work will continue for the 1200-10000 ranges up to n=1.1M. SGS is online and we want to make sure PPS is high enough to remain on the Top 5000.



Thank you again to everyone helping out with this effort. :)

Proth Prime Search Update
k=3 to 9M - ongoing in the 321 Prime Search (trailing edge n=8.5M; leading edge n=8.62M)
k=5 to 6M - (currently at n=5M) (*)
k=7 to 6M - (currently at n=5M)
k=9 to 4M - (currently at n=3M)
10<k<32 to 2.5M - (currently at n=2.5M)
32<k<100 to 2.2M - (currently at n=2M)
100<k<500 to 2.2M - (currently at n=2M)
500<k<1200 to 2.2M - (currently at n=1.5M)
1200<k<10000 to 1.03M - ongoing (trailing edge n=998493; leading edge n=1.005M)

Green represents a completed goal.

Good to know, but this makes me unsure of whether or not we will be able to hit all the goals for this year if we are pushing 1200<k<10000 that far, oh well. It amounts to less low range work for next year.

... Of the recent Proth's above 1M, three have
k < 4000 ..., while there are fourteen with 4000 < k < 10000. ...


The leading edge is the same for 1200<k<4000 and 4000<k<10000, they aren't favoring either.

They? I'm suggesting two counting questions. three -vs- fourteen?
is one. The other is 4000 - 1200 = 2800 k's -vs- 10000 - 4000 =
6000 k's. There are way-more k's in the 2nd range being sent out,
and that "favors" the larger k range by 28-to-60. More candidates
submitted to LLR and more primes found. Substantially.

But, of course, Lennart's right. For a short term 1.0M - 1.1M we
can tolerate a few extra early 2013 primes; I think we were wondering
about 1.0M - 1.25M, but that isn't happening. OK?

We should have changed to a smaller k but I will keep the low n in the challenge.

It is only 24hr.

Uhm; that's "low n" meaning large k, and continuing with
1200<k<10000 to 1.03M - ongoing (trailing edge n=998493; leading edge n=1.005M)

if I'm reading correctly. The smaller k's have n at/above 2M.

I'm seeing
7555*2^1010048+1 is not prime. 4869*2^1010097+1 is not prime.

for tasks that have just been sent, as in
4 Oct 2012 | 13:30:46 UTC 4 Oct 2012 | 13:47:48 UTC


With c. 27 hours to the start of the challenge, looks like
we'll be competing in n=1.01. -Bruce*

2012 Goals - Progress update

Good progress is being made in advancing PPS (LLR) towards its 2012 goals. Let's keep up the good work!!!

Work will continue for the 1200-10000 ranges up to n=1.1M. SGS is online and we want to make sure PPS is high enough to remain on the Top 5000.



Thank you again to everyone helping out with this effort. :)

Two things. First those numbers can not be primes which saves a lot of hard work. Secondly that you should join Aggie The Pew.

This means you have shown that many numbers are NOT prime, as you are sieving that has saved a lot of wasted effort in the LLR search as these numbers will be eliminated from that test.

A prime is a number without factors, factors are numbers that will divide into a number under test in an integer division process (i.e. with no remainder).

Often you will find more than one factor for the same number, technically you always find at least two if you find any, unless the factor is the square root of the number under test. I have over 50 per test reported on average.

2012 Goals - Progress update

Good progress is being made in advancing PPS (LLR) towards its 2012 goals.
Only about one month left. Let's keep up the good work!!!

Work will continue for the 1200-10000 ranges up to n=1.1M. SGS is online and we want to make sure PPS is high enough to remain on the Top 5000.



Thank you again to everyone helping out with this effort. :)

Proth Prime Search Update
k=3 to 9M - ongoing in the 321 Prime Search (trailing edge n=9.18M; leading edge n=9.2M)
k=5 to 6M - (currently at n=6M) DONE
k=7 to 6M - (currently at n=6M) DONE
k=9 to 4M - (currently at n=4M) DONE
10<k<32 to 2.5M - (currently at n=2.5M) DONE
32<k<100 to 2.2M - (currently at n=1.55M)
100<k<500 to 2.2M - (currently at n=2M)
500<k<1200 to 2.2M - (currently at n~1.6M)
1200<k<10000 to 1.03M - ongoing leading edge n=1.03M) DONE

---------------------------------------------------------

Shown here is the status right now.

We will not reach all goals but K=3 - K<32 is done.

32<k<100 & 100<k<500 will not reach the goals :(


We will not start anything above 6M We need to sieve more.

I suggest
k=3 to 10M
k5-k7 suspended to we have a good sievefile.
k=9 to 6M
10<k<32 to 3M
32<k<100 to 2.5M
100<k<500 to 2.2M
500<k<1200 to 2.0M - (currently at n~1.65M)[/color][/b]
1200<k<10000 to 1.1M If all other goals are reached we continue here.

Any thoughts ???

Hi Lennart, can you shed light on the status of 100<k<500? Your post says currently at n=2M, however PPS stats show n at 1.5M, (except for k=121, 157, 193, 225, 253, 265, 295, 385 all with n at 1.7M). Thanks

100<k<500 to 2.2M - (currently at n=2M)

According to http://www.primegrid.com/stats_pps_llr.php upper limit for this range is 1.55M. We run doublecheck now?

The PPS LLR status page was an incredibily heavy page to load (it performed thousands of SQL-queries per person that tried to view it). This has been improved yesterday, so it could be that something has gone wrong there.

Someone who actually knows what's going on with that upgrade will be along somewhen in the future to give a useful reply :)
