P-1 Stats Website!!!
 

Well, after a lot of digging, I have gone through all the missions ever done by mersenne-aries and sorted them all out. I have also started to post the stats on my website.

[url]http://harman.customer.netspace.net.au[/url]

Now, please keep in mind that this my first ever attempt to create a website, so please go easy on me.

I have started this thread as a spin-off of the "missions" thread. The main things that I woud like to be posted in this thread are

1) Suggestions for things to be added to the website
2) Things on the website that need to be fixed
3) etc

There are a few problems with it at the moment (the major one being that there is very little information on it).

1) Some people aren't in the "top p-1ers yet" due to "complications" but I will put them in there ASAP. These people are....
tha
axn1
cruncher
adpowers
chrisblore
call apple
cold fury

2)koekie is in the "everyone's largest factor twice". I will fix this.

3) none of the pages have a "back to home page" yet. I will try to do this. However getting more stats is probably a higher priority at the moment.

This are the problems that I already know about and plan to fix. Any suggestions/bugs/problems, just post them here and i will try to fix them as soon as I can.

Oh, most people are in there using their primenet user name, if you would rather have it changed to your forum name or something else, just let me know.

Ok, I just did a mojor update. Well..... it was a major update in my view anyways...

Things that have been changed

1) koekie now only appears once in "largest factor found by each person"
2) all those people that were missed out in the initial "top p-1ers" should be there.
3) In the "top p-1ers" it now shows their largest factor and the exponent that it is a factor of
4) you can now click on names in "top p-1ers" and it will take you to a new page where it shows all the factors that they have found since the beginning of mersenne-aries
5) every page (that is not the index page) should contain a link to take you back to the homepage.

Could everyone that has done p-1 work, please check their stats and make sure they are correct. I know that you won't know [I]exactly[/I], but if my website says that you have done 50 p-1s and you know that you have done over 200, then let me know and I will see what I did wrong.

If you would like another name other than your "primenet user name", just let me know. However, I would prefer it if it was still a name where everyone knows that it is them. For example, S130260 is James Heinrich. So in that sort of case it would be good to change the name because no one knows him as S130260.

So, what else needs to be changed/added/deleated from the website. One more thing that I would like to add is some stats on the length of exponents that we have found. (Like how many with 20 digits, how many with 21 digits etc.)

All and any suggestions are welcome. It doesn't matter how small.

Oh, one more thing that I should mention is that only the stats in "completed missions (plus my own results.txt files of my computers) have been included in the stats. I realise that there are some sets that are finished in the forum, but just while I am trying out some different things with the website, I won't be including the new sets for the next week or so. Once I have worked the kinks out of the website and added the stuff that is suggested (hint, hint) I will include all stats and move all the completed missions into the "completed missions" sub forum.

On [URL=http://harman.customer.netspace.net.au/lf_top20.htm]http://harman.customer.netspace.net.au/lf_top20.htm[/URL] factors are not strictly in decreasing order.

Well spotted. Should be fixed now. I mustn't have set a 2nd sort value.

Missed this one :wink:

A few of the largest factors are composites.

Ok, I know why my program didn't pick that one up. So at least that is a start.

[QUOTE=smh]A few of the largest factors are composites.[/QUOTE]

All the factors on my page haven't been checked to see if they are prime. This is probably something that should be considered though. It is a pity that prime95 doesn't "factor the factor" in the first place...

from the homepage: the column "P-1er" has a link to show "all factors found by..." . Would be possible to sort that page descending, by factor, instead of ascending, by exponent? Not that it is of any importance, just for a matter of "graphical order"... :whistle:

You did it fast and well, thank you!

Luigi

Thank you Dave for your effort. I like it very much. :cool:

[QUOTE]It is a pity that prime95 doesn't "factor the factor" in the first place...[/QUOTE]

Or at least says it's prp or composite.

Same for the cofactor, especially for ecm on low numbers. Wouldn't be to hard to add in a next version, would it? :bow:

How about adding a column showing the number of bits in each factor?

All p-1 missions 1300 49[/CODE]

Ok, assuming that I haven't made the same error again (which I might have) these are some other ideas of why we get different answers...

1) You have inlcuded your entire worktodo file, which contains sets that you have half finished but have not reported on the forums.
2) You have done p-1 work that was not a part of mersenne-aries - either through doing first time LL tests or doublechecks.

This is what I have come up with. Please, please don't take it as "I am right and you are wrong" because that is not what I mean at all. I was wondering though if you could compare these stats to your stats and see if there is any sets that I have not included in my stats that I should have.

Those 3 sets above that I have mentioned haven't been moved to "completed missions" have not been added to your stats yet. However, as soon as I make sure that everything that is currently in "completed missions" has been counted properly, I will update all the stats and move the completed missions that people have done into the "completed missions" sub forum.

[QUOTE=dave_0273]This is what I have come up with.[/QUOTE]And that looks right to me: including the not-yet-moved missions comes pretty close to the numbers I have; I imagine the last found factor and few others checked come from the last two sets of 100 I'm working my way through now. So I don't think you have any errors, sorry to make you do that extra work :redface:

Is there any status file on PrimeNet that can be parsed to get this information? I'm relying on user-submitted [i]results.txt[/i]; Dave - it sounds like you're relying on user-posted data in the forum, or did I misunderstand that? I'm curious how you're extracting that data? And how you're generating your stats site in general actually :)

This might be too much work to be worthwhile, but it might be interesting to collect stats on the minimum B1,B2 bounds that would have found each factor. (i.e. if P is the factor of 2^N-1 find the two largest factors of P-1 other than N).

[QUOTE=dave_0273]Could everyone that has done p-1 work, please check their stats and make sure they are correct.[/QUOTE]
One of these batches was not counted. Note the thread title on one of them says 100 exponents but it is actually only 50. In total I have tested 100 exponents and found 5 factors.

Ok, I just did another update on the site. Nothing "new" but i just included the rest of the sets that were in the forum that were completed.

From now on, to recieve credit on my site for the mersenne-aries work that you do, you could please do the following things to help me out...

1) Post the entrieds from your results.txt file that corespond to the work that you did for that set
2) Please make sure that the copy of prime95 that you are using is registered with primenet

ie) all the "important" lines in results.txt start with "UID: ..." otherwise my program doesn't know who to credit the work to.

If there are any errors on my site, or any bugs that you find, or any suggestions in general, please post them here or PM them to me.

This is my first website so it is taking me a little while to get it up and running properly.

Hi Dave,

I found a 20 digit Factor

26613239 65
F 46466134729650936071 15-Aug-04 18:28 Team_Bundu3

Does it count?

Cheers, Mark

My website only keeps track of work that has been done by mersenne-aries. The reason why I keep track of it is because we don't get any (primenet) credit for the work that we do. Therefore, to keep us competitive and interested in mersenne-aries work, I keep track of the stats.

I am assuming that your factor was found through an exponent assigned through primenet, so you won't get credit for it on my site but you will have primenet credit for it. Just go to [url]http://mersenne.org/ips/accounts.html[/url] and log into your account and it will show you the credit that you recieved from it.

Sorry bud. I obviously didn't read the posts closely enough :blush:

A question for Dave and James:

Dave, I did 3/4 of my work, and already found 8 factors. Should I wait that you move the thread on "completed missions" after the end of my factoring task to see the stats on your site?

James, If one pastes his results.txt more than once on your page, is there a filter that cut out the duplicated rows? If so, I could start my update by now... :whistle:

Luigi

[QUOTE=ET_]James, If one pastes his results.txt more than once on your page, is there a filter that cut out the duplicated rows?[/QUOTE]With my stats, you can submit [i]results.txt[/i] as many times as you like and old work will be filtered out and only new results accepted. That way you don't need to remember exactly when you last submitted results, or worry that you might have missed some.

ET_: Wait until that you have finished the entire set (I assume that it is the block of 99 that is currently assigned to you in the forum) and then paste the corresponding results from the result.txt file into that thread.

When the "weekly" status files come out, I make sure that all your work was reported to the server properly and then move the thread to completed missions. It is on this "weekly" basis that I will update my site.

If you ever do any work and it hasn't been moved yet to the completed missions thread, it won't be on my site yet.

Thank you dave, thank you James.

Luigi :rolleyes:

Ok, I just updated my site again.

Nothing new on the site, I just updated all of the stats again....

I updated all the stats again....

If you find any errors, please let me know.

You are never going to belive it, but I just updated my stats site again.

I don't update it very often as I have to do it all manually, however, starting now I am going to try to update it every 1-2 months rather than how much it has been getting updated at the moment.

Please have a look at your stats. If you find an error, post it in here and I will try to resolve it.

If your name doesn't appear, let me know. The way that I have written my program, I have to manually enter each new person's name (which takes like 2 seconds) but, if it is not there, it disregards all your results lines as it comes upon them. All I would have to do is add your name to my program and re-run it and you would have all your stats there.

Any other suggestions, please feel free to post them here, however, please be gently, as this is the first webpage that I have ever made.
