This is a thread for general news for No Prime Left Behind (NPLB)

A few topics of interest to get us started:

1. Please post all results files in the status thread upon completion of your ranges or alternatively you can Email them to me at:
gbarnes017 at gmail.com. Also, if you can please post or mail past results to me that you still have available, that would be helpful. My apologies for my initial indecision on this.

2. Karsten (kar_bon) is working on a scoring system for NPLB. Please post your opinions and thoughts in the 'statistic pages' thread.

3. We just picked up our 9th top-5000 prime, which moves us into a tie for 8th place among all prime search projects. With ~20 more, we'll be in 6th place. This is where the action is at! :smile:

4. We are currently in the process of sieving 300<k<400 for n=260K-1M. The entire range so far is sieved to P=100G with a portion of it sieved to ~P=300G. Look for a 'sieving help' thread late this week where you can help us with the sieving if you like.

On #4, when sieving is complete, this will be an exciting range to test with many more possibilities for varied-type searches. Although we will have a drive #3 for a large portion of it that is similar to drive #1, we will leave ~7-10 k's for individual reservations. Small 'mini-drives' amongst 2 or 3 of you are good possibilites for this range. There are other k's where testing can be started at n=500K or n=600K for those of you who like BIG primes but don't want to wait for the big team drive to get there!

Karsten has completed an excellent scoring system for NPLB. See [URL="http://www.mersenneforum.org/showthread.php?t=9930"]this thread[/URL] for info. about how the scoring was arrived at. There is 'bonus scoring' for helping out with some of the lower ranges in drive #2.

Let's get some friendly competition going. Karsten is kicking our behinds right now! :grin:

24-hour NPLB LLRnet rally 2/23 7 PM GMT
 

There will be a 24-hour NPLB LLRnet rally this weekend beginning at 7 PM GMT Saturday 2/23.

If you've never participated in a rally before, they are great fun with individuals competing against each other and teams trying to knock each other off! Check out all of the details in the [URL="http://www.mersenneforum.org/showthread.php?t=9973"]24-hour rally thread[/URL].

Port 100 for 24-hour rally
 

Just a note in case you missed it: The rally this weekend will be on port 100 to get ranges of primes filled in.

Everyone bring everything you've got and have fun! :smile:


Gary

I kindly asked to Kirk Pearson, from [URL="http://distributedcomputing.info/index.html"]distributed Computing site,[/URL] to add NPLB as a math distributed computing project. Check [URL="http://distributedcomputing.info/ap-math.html#nplb"]here[/URL]. With time NPLB will gain visibility.

After I finish a range and report the lresults.txt, should I delete the old lresults.txt so the file doesn't just keep growing? Is it recommended to report the lresults.txt after every range, or run a couple ranges before e-mailing it? Also, do you have a preference for receiving them by forum or e-mail?

I'm fine with you posting them here or Emailing them. As long as they're not too big, posting them here is slightly preferred but the size limit restricts that for very large results. I can't access my Email from work.

It's best to have separate lresults files if there is a gap between the ranges tested. So if you reserve several consecutive files at once, you can let the results 'pile up' in one file and send or post them all at once. But if you reserve one range, then others reserve some, and then you reserve another range, the files should be separate. If there is a gap between the ranges in a single results file, I have to separate them because there will be other results that come in in between them. I need to be able to see at a glance that we have results files for all ranges.

Please see [URL="http://www.mersenneforum.org/showthread.php?t=10034"]this new thread[/URL] about future project direction and server needs.

Sieving for 300<k<400 for n=260K-600K has completed. Drive 3 will start late Friday/early Saturday for the new k-range.

The big file is now prepared and ready. We will be sending a large top-5000 range to IronBits for his new LLRnet server after doing some calculations as to how much will be needed for ~2 weeks including a rally. We'll also post some n=2K files for individual reservations.

This will be an exciting range to process. With < 1/6th as many k's, we'll progress quickly upwards until we catch up with drive 1.

The intent for ~1-3 weeks is to have 3 servers running until drive 2 is complete. One will be processing ranges at n=~340K, another at n=~370K, and the other at n=~290K. So there will be many flavors of primes to search for! :smile:

Sieving for 300<k<400 for n=600K-1M is continuing...ETA is mid-late March.

Edit: The drive has started!


Gary

We have added a [URL="http://www.mersenneforum.org/showthread.php?t=10042"]new thread[/URL] that shows all info. about the LLRnet servers that are currently running at NPLB and where they are currently at in testing.

Great work in getting the info. together Karsten! :smile:

It is now official. k=400-1001 for n=320K-340K is complete and verified! :smile:

NPLB found a total of 49 new primes and verified 9 others for a total of 58 primes.

Karsten, I have double-checked your rieselprime site, the NPLB pages for team drives 1 and 2, and the top-5000 site against primes in all the results files that I have. All primes are listed and are correct. I also double-checked my listings in the first post of each drive. 1 prime that was missing is now listed.

I was only missing results files for 4 out of 100 n=200 ranges! Very nice job in sending them everyone!! :smile: I messed up on 2 of them and didn't get them pulled from a web link and the person no longer had them available. I should be getting the other 2 this weekend.

I will start listing the primes and completing the ranges on Primesearch tonight.

Great work everyone. Let's keep it going!

Sieving k=300-400 status and individual-k searches
 

k=300-400 will be done sieving for n=600K-1M by ~April 1st.

Some of you may have wondered about individual-k reservations like we mentioned in our initial project definition. To keep things a little simpler for scoring purposes, we have intentionally maintained the current file reservations process. But when the k=300-400 sieve is done, we will start taking some reservations for individual k's for n>600K and providing sieved files for them. For any k=300-400 "presumably" already contiguously searched to n=600K by others, we'll start doing some searching on those individual k's above n=600K.

7 k's currently fit the criteria. There are also many more that were previously searched up to n=300K and from n=480K-600K. So once we reach n=480K on drive 3 to effectively fill the gaps in them, we'll also open those k's up for individual reservations above n=600K if people enjoy searching them in that manner.

Keep in mind that we won't stop searching these k's up to n=600K in drive 3. We still want that partial double-checking to be done.

This should add a little variety to our standard methods here and get us a nice score boost on the top-5000 site whenever a prime is found. I don't want things to become too stale. As Anon said, variety is the spice of life. :smile:

Are you sure (April 1st) ?:cool:

[quote=em99010pepe;129730]Are you sure (April 1st) ?:cool:[/quote]

lol; no, really, it's not an April fools joke. Actually the sieving should be done April 1st but it'll take me a little while to pull the factors together off of 10 machines, remove them from the big file, set up a thread with appropriate instructions, divide up the files, post them on my web site, post them in links here, etc. So if you want an exact date, make it April 3rd and maybe April 2nd if I'm not too busy on that day.

Our work is never done but it's a FUN work and that is all that counts! :smile:

Ranges / primes reported at Primesearch
 

I have now reported primes and completed n-ranges at the Primesearch site for n=20K ranges that I have all the results files for. With just a small percentage of our current total reported, we're already 6th place on digits in our primes and 12th places both on # of primes and ranges completed at the site.

See [URL="http://www.mersenneforum.org/showthread.php?t=10166"]this thread[/URL] for more detailed info.


Gary

Individual-k reserves for high n-ranges available
 

We now have individual-k reservations available for 5 low-weight k's for k=300-400 and n=600K-1M. See the [URL="http://www.mersenneforum.org/showthread.php?t=10179"]individual-k reservations thread[/URL].

Port 5000 a priority for a while...
 

I'd like to make port 5000 a priority for a while due to some prior missing results that need to be processed at the end of the current set of k/n pairs that are in the server. See particulars in [URL="http://www.mersenneforum.org/showpost.php?p=130747&postcount=9"]the results file thread[/URL].


Thanks,
Gary

Top priority for temporary LLRnet port 8000
 

IronBits has created a temporary LLRnet server to process the n-range of 425K-437K for drive 3 to fill in a large gap in testing. We'd like to get this range filled in as quickly as possible. This is a potent range with low k-values and no known primes.

If you are currently running port 5000 or would like to otherwise assist, I'd like to suggest a change over to port 8000 for a while until the server is dried. The server info. to put in the llr-clientconfig.txt file is:

server = nplb.ironbits.net
port = 8000

Everthing else should be the same.

Since this is only a temporary server, after all k/n pairs have been processed, it will go away unless it is needed to fill in 'holes' somewhere else.


Thanks,
Gary

Delays on my reservations...
 

Due to unforseen circumstances, there will be approximately a 1-week delay in continuing with and completing most of my manual reservations. My LLRnet processing on port 8000 is mostly not impacted.

I'll let everyone know if anything else changes.

In other news, we're doing great on port 8000; we're already at n=426.7K of the 425K-437K range. At this rate, we should be done with it in just over a week.


Gary

Upcoming vacation April 17-19
 

Now it's my turn to take a vacation! :lol: I'll be on vacation from early on the 17th to late on the 19th; I may or may not be able to get on mersenneforum at all. This shouldn't have much of an impact on my various responsibilities, since it's only a 3-day trip. Just wanted to let you all know ahead of time, though, so you won't just think I went AWOL. :wink:

GREAT WORK Karsten!!

Many of the missing primes for n=100K that I had already found will be corrected in the next month. I had to wait for Michael Hartley to uncomplete them for the people who originally completed the range and then wait another 2 months for them to get in expired status, which most of them will be by the end of April.

Most of n<100K should be corrected by the 2nd week in May. Any range that someone missed a prime in and didn't correct will be expired by Mike, reserved by NPLB, and completed by NPLB. This will have the effect of removing a range completed by someone else and giving it and a prime to us.

Moral of the story...do your ranges right or correct them or you lose credit for them.


Gary

There will be an LLRnet rally on May 3rd-4th on port 300. See related info. [URL="http://www.mersenneforum.org/showthread.php?t=10256"]here.[/URL]

the pages for Team Drive #1 and #3 and the 300<k<2000 page are updated!

PS: the last one without new completed ranges so far.

I'll be going on vacation from June 28th to July 5th. I hope to be able to get on mersenneforum at least once a day, but I won't have any access to my LLRnet processing tools and whatnot. I'll be sure to make sure everything on that front is all up-to-date and ready to go before I leave. :smile:

my vacation begun 2 days ago and ends on 07.Aug (perhaps 2 weeks longer, don't know yet).
so the stats for the race have to wait some more days.
i need the results from L6 only and i'm able to compile them the next days.
sorry for the delay and much success on finding more primes!

Edit: i got the results per mail from Anon yesterday, thanks.
so i can make the stats now.

hello to all,

Sieving k=401-1001 for n=600K-1M has started!
 

Bruce has kindly dedicated a good portion of his substantial computing power to sieving NPLB's next attack: k=401-1001 for n=600K-1M.

The new goal now is to complete drives 1 and 3 to n=600K by Oct. 31st and that is when Bruce is shooting to have sieving done.

With speedy 64-bit sr2sieve running on speedy 64-bit Linux machines, a very rough estimate of the optimal sieve depth is P=25T, although that has not been determined yet.

To give you an idea of the substantial resources it takes to properly sieve 300 k's at such a high n-range, I estimated that it will take 4-5 CPU years! It looks like Bruce will have no problem meeting that date himself but if we need help from the team, I'll post sieving reservations as needed.

With the newer speedy sr2sieve and 64-bit systems, we will also look to do some additional sieving on drive 3 for n=600K-1M after completing the drive 1 sieving. I'm estimating optimal to be P=20T-25T there but it is only currently sieved to P=14T, which was optimal for 32-bit systems at the time.

So come along and load up your machines as we attempt to complete drives 1 and 3 to n=600K by Oct. 31st! :smile:


Gary

my ftp-login for [url]www.rieselprime.org[/url] works again so all changes i made will available there today!

i updated all ranges for 301<k<1001 on the summary page.
i inserted the missing primes Gary wrote in the threads for drive #1 and #3.
the page for the Riesel-problem is ok now too (edited the error Siemilink found), and the corresponding k in 10^5-page.
i plan to insert all primes found in the last month (mostly by Burt in the range 1000<k<3000 and higher ones).
the menu (left side of [url]www.rieselprime.org[/url]) shows the old dates but the pages itself contains the last edit date.
i will change these in the near future.
while my vacation i fill in some small primes for 10^7<k10^9 for n<50k to delete all phrases like "(90 primes to 50k)".

OUTSTANDING Karsten!! And I was thinking about assisting you in some way with that effort. I know what a huge undertaking it must be.

Thanks for updating things!


Gary

next updates are online.
perhaps there're some primes missing in the team-drive-pages.
i begun to convert the date-format from dd.mm.yyyy into yyyy/mm/dd for the data-pages (first NPLB team drive #1 and 300<k<10000-pages).
next pages will follow.
(to Gary: also "nnn (...)" into "nnn, (...)" !)

For those interested, the sieving effort for: k=401-1001 for n=600K-1M.

is now at 2.35T and moving.... :smile: and a backup of the dat file has been sent to Gary. Only have to go to like 20 to 25T

sieving is completed to 4.1T

Second spot to PrimeSearch on total of number of primes. Well done.

i updated now all edited files on [url]www.rieselprime.org[/url] (without any problems this time).
so no need to refer to the de-server. (will make a note there)

i finished also updating other pages like 1001<k<1999 for 10k<n<35k (data from henryzz and me and small primes from lavalamp (coming soon)).

i got no access to rieselprime.org again!

so for now and next times:

if [url]www.rieselprime.org[/url] is not available, try [url]www.rieselprime.de[/url]!

there's a notice to go to the org-domain but if not available go further (second link there)!

this time i made some changes and many new primes from lavalamp (20000<k<200000,0<n<10000(0)).

hope this helps.

the k<300 page on [url]www.rieselprime.org[/url] is available again with current data so far.

i also updated the 'Historicals and Milestones' thread with some new data!

EXCELLENT WORK Karsten! And thanks for checking and finding some errors on my page.

I think you mentioned in a PM removing the 'missing at Primesearch' verbiage from the k=300-2000 page. Here is what I would suggest instead:

Just put an asterisk by the primes that are missing at Primesearch with a note at the top about what the asterisk means. Or you can use some other method of highlighting them to let us know that they are missing. I think that will save us a lot of time in the future knowing which ones are missing.

SOME day we will have our threads, your k=300-2000 page, the top-5000 site, your k<300 page, my k<300 page (which I may stop updating now that yours is up to date), and Wilfred Keller's Prothsearch k<300 page all in sync with one another! :smile:

does anyone noticed that NPLB is the second listed project on 'Prime Search Projects'?
i used to click on the last entry there but not today!
thanks ????

Yes, I also wondered first. The reason is that 321Search was archieved and Xyzzy rearranged the projects.

--nuggetprime

Yeah, I had noticed. I had requested it a few months back. Nice to see us moved up a little. :smile:

The CRUS project was also moved up...to the #3 spot.

Life is good. :smile:

Due to the fact that most of are very busy with efforts elsewhere or here and most of the Free-DC folks are running OGR mostly full time, we'll be holding off running another rally for ~2-3 weeks yet; preferrably after the OGR project is complete and after David has completed the automated stats set up on our servers.

David is working almost non-stop in his spare time to get the automation set up. Thanks David! :smile:

Sorry for the delay!

We have great news! We now have files sieved up to P=24.65T for our individual-k reservations drive! Sieving has paused for a while but will be continued up to P=26T a little later on.

Come and reserve some well sieved files for k=300-400 and n=600K-1M now! :smile:

Out of town Friday-Saturday
 

Hi all,

I will be out of town beginning tomorrow (Friday, Nov. 7) and returning late Saturday (Nov. 8). I will most likely have limited or no access to mersenneforum, but regardless I should be back on Sunday whereupon I will of course have full access. :smile:

I apologize for the short notice--I had intended to mention this at least a week in advance, except that it completely slipped my mind. :rolleyes:

Max :smile:

the new page for the Race #8 is online now!

Threads for team drives 5, 6, & 7 have now been started for the huge range of k=400-1001 and n=600K-1M. Keep right on crunching along with us as we undertake this huge endeaver and find many big primes! :smile:

The applicable servers are in the process of being loaded with the appropriate ranges at this time. Manual files will be posted after the 1st drive is complete.

Karsten, in the next few days, can you create a new web page at your site for each of our new drives and provide me with a link to them? I'll then add the link to the 1st post in each of the drives like we've done with our other main drives. Thanks!

Sometime in the next week or so, we'll get the k=1005-2000 drive kicked off for n=50K-350K. In late Jan., I'm hoping we'll be ready to start that range for n=350K-500K. There are 100's of small and medium-sized primes that still need to be found in that area. Likely, we will start a sieving drive shortly after the 1st drive is done for the higher n-ranges of k=1005-2000 to guarantee that we will be ready to start searching for top-5000 primes in that area by late Jan.


Gary

It appears that Michael Hartley's Primesearch site may have gone the way of Riesel Sieve. There has been no way to connect to it in nearly 2 months.

Therefore like I recommended at CRUS for the Riesel Sieve site, I am recommending here for the Primesearch site that people remove all links to it from their various web pages, posts, and threads. I have already removed it in two places here. If you see other links to it, let us know and we'll get them removed. Having links that don't work in main project pages does not look very good.

I will send an Email to Michael shortly but the problem has never been this bad. I believe the site that it is hosted on has little space available unless he pays a fee. I suspect that we may have filled it up to its max when I entered everything through n=540K and starting reserving final ranges for n=560K-600K. It was at that point that it went down and I haven't been able to get back on it.

Because of the instability of the site, even if it comes back up, I would suggest that we don't provide permanent links to it in web pages, threads, or posts. Off-hand references to it can be made, perhaps in Email or PM's, but it looks very bad to any new searchers to have invalid permanent links in project pages, even if they are only invalid 20-30% of the time.

I have now verified the results files for the range of n=540K-600K. All primes are correct on the top-5000 site, the 1st post of the 1st drive, and Karsten's 1st drive page. There was a small problem on the k=300-2000 page:

The prime for 885*2^564282-1 is listed as [B]855[/B]*2^564282-1. Karsten, if you can take care of that, everything will be synced up.

If the PrimeSearch site ever comes back up, I'll attempt to get all of the primes and ranges submitted for n=540K-600K.

Once again, thanks to all for an excellent finish on the 1st drive to beat the year end goal by over a week. We could not have done it without everyone's efforts! :smile::flex:

The 1st drive is now considered officially complete!

Look for a new sieving drive for the k=1005-2000 range in the next few hours.

High-priority sieving drive...
 

A high-priority team sieving drive for k=1005-2000 has started [URL="http://www.mersenneforum.org/showthread.php?t=11204"]here[/URL]. Please consider helping us out as we attempt to get it sieved far enough to begin a testing drive before the 5000th-place prime reaches n=350K. :smile:

NPLB primes found records in 24 hours
 

Here are some interesting records for primes found by NPLB in any rolling 24-hour time frame. All times are GMT.

Most total primes found for n>260K where there were any number of top-5000 primes: 26
2 top-5000/24 non-top-5000; March 6th @ 12:01 AM to March 7th @ 12:01 AM.
(Same record for up to 2 top-5000 primes.)

Most total primes found for n>260K where there were 3 or more top-5000 primes: 25
3 top-5000/22 non-top-5000; March 5th @ 7 AM to March 6th @ 7 AM.

Most total primes found for n>260K where there were 4 or more top-5000 primes: 19
14 top-5000/5 non-top-5000; March 11th @ 8 AM to March 12th @ 8 AM.
(Same record for up to 14 top-5000 primes.)

Most total primes found for n>260K where there were 15 or more top-5000 primes: 18
16 top-5000/2 non-top-5000; March 11th @ 3 AM to March 12th @ 3 AM.
(Same record for up to 16 top-5000 primes.)

Most total top-5000 primes: 16
March 11th @ 3 AM to March 12th @ 3 AM.


These will be some records to shoot for on our new k=1005-2000 drives in the near future! :smile:


Gary

I've added a team drive thread for our new k=1005-2000 and n=350K-500K effort as well as a separate primes thread for that k-range.

To make some room for 2 more stickies, I unstickied the 'join a team' thread.


Gary

I have temporarily stickied the thread about Peter Benson's search area that overlaps our upcoming 9th drive [URL="http://www.mersenneforum.org/showthread.php?t=11312"]here[/URL].

Please provide opinions if you would like.


Gary

i've updated the pages for Drives #5-#7 with all data to 2009-01-11 00:00 so far.

the page for Drive #9 follows the next days.

i also generated a new page for NPLB-Doublechecks!

all available under [url]www.rieselprime.de[/url]

We are starting a low-priority results file file-in effort for the missing results from Peter Benson's files that he sent us for k=1005-1400 for n=200K-479264.

See details in [URL="http://www.mersenneforum.org/showthread.php?t=11377"]this thread[/URL].


Gary

I have verified all of the results processed to me for the 5th, 6th, and 7th drives vs. our original sieved files. I also checked all primes vs. the top-5000 site, the 1st post in each thread, and Rieselprime.org.

Other than 1 prime not listed in the 1st post of one thread and 3 missing results from a manual range that have since been corrected, everything looked great.

Karsten the "official" contiguous search limits are now:

k=400-600; n=615K

k=600-800; n=619K

k=800-1001; n=610K


Gary

[quote=gd_barnes;159813]k=400-600; n=605K (will likely be n=615K upon the completion of a small part of a manual range shortly before or after the rally)[/quote]
I just completed my range and posted the results in the Drive 5 thread.

[quote=Mini-Geek;159820]I just completed my range and posted the results in the Drive 5 thread.[/quote]


...checking it now and will edit the above post about drive completion limits when done.

Edit: verification complete.

i made 2 quick graphs here: [url]http://www.rieselprime.de/NPLB/Graphs.htm[/url]

there you can see all listed primes in the PrimeDatabase for 2 different ranges of k and n.

the "great hole" in the 1800<k<1900 range is the eyecatcher! (2nd graph).

Excellent graphs Karsten! :smile:

Funny you should mention that about k=1800-1900. I just now submitted a k=1800-1900 prime. Also, LaurenU2 has a k=1800-1900 prime to submit from several hours ago. He got an automated Email for it. I also sent him an Email making sure he knows how to submit primes. I think he has 2 or 3 to submit now.

It's amazing that we had to wait until n>370K for a new k=1800-1900 prime when there was only 1 n=350K-375K ever previously found.


Gary

i made another Graph of all NPLB-Drives and some other ranges to 'see' clearly where/what we're crunching!

see the link 2 posts above!

PS: some (current) ranges will added the next days!

I have deleted the poll/thread titled "NPLB will help Primesearch overtake RPS".

While these kinds of polls can be fun, I felt that it would only serve to increase the rift between the projects.

Please PM me with any comments or complaints about this decision.


Gary

I am happy to report that Ian (MyDogBuster) has been added to the list of admins for the NPLB project. Ian has been a great help to NPLB and I need some time freed up to give a little more direction to the CRUS project so his help will be greatly appreciated.

Welcome to the world of tedious admin duties Ian! :smile:


Gary

I have some exciting news. After getting approval from Michael Hartley and Chris Caldwell, I have recently been given admin access to the PrimeSearch project ID at the top-5000 site. The ID [URL="http://primes.utm.edu/bios/page.php?id=518"]here[/URL] now has a link to our forum here and describes what we are doing with the NPLB effort as it relates to the, now defunct, PrimeSearch project.

This should provide much better exposure for the project!


:smile: Gary

That is great news Gary.

That is a great relief and now it is more official...that we are having a great deal of fun :p

:smile: Gary[/quote]
Cool! :cool: I especially like the blurb you wrote for the project--nice writing! :smile:

A note of interest:

Karsten has begun sieving k=2000-3000 for n=20K-1M for NPLB's next big effort. Bruce had previously offered to do a lot of the sieving on our next effort after finishing k=1003-2000 for n=500K-1M to P=30T so I have suggested that he coordinate with Karsten when he is ready to.

I did not personally suggest this but was leaning that way. The other option was to start an even bigger sieve for k=300-2000 for n=1M-2M but I think that we can wait probably until early 2010 to start on that. That will be a monster effort that will likely need to be sieved to somewhere around P=100T-200T.

The nice thing about k=2000-3000 is that we'll be able to test all 500 k's since (at least as of this posting) no one project or person is searching a large contiguous k-range within the area and there will be far less already known primes, i.e. less double-checking.


Gary

I have posted a low-priority mini-drive for k=3010-3200 and n=420259-500000 with manual files only that Chris had started. Details are [URL="http://www.mersenneforum.org/showthread.php?t=11706"]here[/URL].


Gary

i've marked the range 1003 <= k <= 1399 complete upto n=500k!

next (perhaps today): range 1400<k<1600 upto n=520k!

i updated the k<300 page too!

I have sent a couple of questions to Chris Caldwell at the top-5000 site about changing the ProjectID from PrimeSearch to No Prime Left Behind. I can do it easily enough and it lets me do so but I'm unsure of the impact that it will have on existing and future new prover accounts.

If there is no impact and a prover account can be set up with the initials of "NPLB" for a project name, look for the ProjectID to be changed either on Tuesday or Wednesday. :smile:


Gary

That will be a great help! Nice work.

Everything is coming together nicely :smile:

[QUOTE]I have sent a couple of questions to Chris Caldwell at the top-5000 site about changing the ProjectID from PrimeSearch to No Prime Left Behind.[/QUOTE]

Yea? Another piece of the puzzle being solved. :cool:

Chris has questioned our intent in changing the project name since former PrimeSearch project primes are still in the top-5000...49 to be exact.

I will be following up with Michael Hartley on it. It may be a little while yet.

Politics that I love so much...:rolleyes:


Gary

Changing the project name to NPLB would be great.

If however that was to impact on the existing prover accounts there would be tears alll round.

Is Chris able to split those primes back to Primesearch?

There would be no impact other than the project name within the prover account would change.


[quote=henryzz;170312]Is Chris able to split those primes back to Primesearch?[/quote]

I would have to ask him. I believe it would be possible but I think it would be a huge undertaking both on my part and his. I'd have to send him a huge list of primes that either: (1) PrimeSearch previously found -or- (2) We have found since starting this effort. I think then a whole new set of proof codes would be needed, which I or someone here would have to do. Then Prof. Caldwell would have to take a lot of time to move them all over. I think it would be time-consuming no matter how it is done.

I'm composing an Email to Michael Hartley now. I think he'll go along with the simple name change. I am offering to continue respecting his contribution to our effort by continuing to show how PrimeSearch started in the description of our project as it is now. I would do that anyway because he deserves that respect. The original PrimeSearch site was very state of the art when it was created around 2000 or 2001. I'm sure he spent a lot of time at it.


Gary

The turn around was much faster on the top-5000 project name change than I expected. Here is the status:

Shortly before getting the approval from Michael Hartley to change the name, Prof. Caldwell had suggested that it be called "No Prime Left Behind (formally PrimeSearch)" when the project is displayed in the list of top 20 projects. I thought this was an excellent idea and Michael seemed happy that we decided to do that.

Then we get down to the nitty-gritty:

1. I have changed the "Username" from "Primesearch" to "NPLB". This is only a 16-character field so that is the only reasonable abbreviation that I could put in there.

2. Prof. Caldwell needs to change a "Surname" or something else so that it shows "No Prime Left Behind (formally PrimeSearch)" in the list of projects.

3. Prof. Caldwell needs to change a "Surname" or something else so that it shows "NPLB" within the proof codes.

There must be 3 different fields but I don't know what they all are. For RPS, their Username is RPS, their project name in the top-20 list is "Riesel Prime Search", and their project name within each proof code is "RieselPrime"...all different.

My hope is this: When people enter new proof codes, they only have to enter "NPLB" for the project name. I don't know what that keys off of. I had thought it would key off of the Username but clearly that is not the case with RPS since theirs are different nor us because none of our proof codes changed when I changed the Username from PrimeSearch to NPLB.

Another admin duty (mostly) done. :smile:


Gary

Nice job Gary. :tu:

So we have to do a new prover account proof code for nplb? Just to make sure I understand you correctly?

[quote=Brucifer;170473]So we have to do a new prover account proof code for nplb? Just to make sure I understand you correctly?[/quote]

No. The project name within all of the existing proof codes will automatically change itself when Prof. Caldwell makes the change. It should all be seamless.

As for entering new proof codes, that only applies to new people who have not searched for us previously.

It is now official: Our project name at the top-5000 site is:
No Prime Left Behind (formerly PrimeSearch)

See our listing in the rank of projects at [URL]http://primes.utm.edu/bios/top20.php?type=project&by=PrimesRank[/URL].

Hooray! :smile:

The Username and the name in proof codes have also been changed to NPLB. This should be virtually seamless and will have no impact on people who have already set up proof codes for our project.

For new people creating a new proof code for primes, on the proof code page, after selecting Jean Penne's LLR under the software section, in the box that says "None" towards the bottom, you should enter:

NPLB, srsieve

There must be a comma in between and I believe it is case specific.

I have also edited our project description slightly to more specifically recognize the contribution that the original PrimeSearch project made, the # of top-5000 primes still remaining from its existence, and when NPLB started. See the new description at [URL]http://primes.utm.edu/bios/page.php?id=518[/URL].

Max, I am now in the process of changing the prime submission instructions on all of our applicable primes threads posts. If you have copied any of those over to the new forum, please make the same change.

I haven't copied anything over yet but the "Come join us!" thread. Actually, come to think of it, the instructions for reporting primes may not even end up getting copied over until we do the big post transfer from this forum; that's due to the fact that they're part of specific report-primes-here threads, rather than separate instructional threads. I may, however, create a new, non-drive-specific thread containing instructions for reporting top-5000 primes; we may want to eventually just link to that thread from the individual report-primes-here threads, with range-specific details specified in the specific threads. That way if something in the top-5000 reporting process changes, we only have to update one thread. :smile:

I have a prime to enter from my independent search so I'll be the guinea pig to see if everything still works.

Edited: Happy to report that everything works just fine.

I have moved the discussion about the manual stats import to our stats database to a new thread [URL="http://www.mersenneforum.org/showthread.php?t=11824"]here[/URL].

Due to the huge # of stickies that scroll off the bottom of the page on most monitors, I am unsticking the following threads:

The sieving drive since all ranges have been handed out.
The help needed on ports IB4000 and 5000. Most everyone should have had a chance to read that one now. Later on I'll delete it.
The join a team. I think that most new members have now stated a team preference.

At the end of 3 days from posting or when the prime is reported, I'll delete the MrOzzy report a prime thread.

The bottom of the stickies still seems to scroll off the bottom much of the time but it's not so bad now.

If anyone feels strongly that any of these threads should remain stickied, let me know.


Gary

i've marked all 1401 < k < 1999 tested up to n=660000 (some are higher)!

this was a great update for that range.

congrats to all who participated here!

thanks.

OUSTANDING!! That's music to my ears. An excellent achievement for the project.

The goal when we started k=1003-2000 was to clean up that area. Consider it officially "clean" now. :smile:

I'll follow up with Peter Benson to see if he has completed k=1005-1400 up to n=600K yet. It appears that he may be. Regardless, that area is "clean" also with all ranges officially filled in up to n=500K.

Karsten: Your next task: Update all k=400-1001 up to n=680K or 690K. :-)

The next major task for NPLB is to clean up k=2000-3400, which has now become quite messy.
