Team drive #10 k=1400-2000 n=500K-1M
 

[COLOR=black][FONT=Verdana]This is team drive #10 for No Prime Left Behind. We will be searching all k=1400-2000 for n=500K-1M.[/FONT][/COLOR]

Karsten (kar_bon) has created a web page that shows details for the drive [URL="http://www.rieselprime.de/NPLB/Drives/NPLB_Drive10.htm"]here[/URL]. He maintains a site that has almost all known Riesel primes. There is a page for the range of 300<k<2000 [URL="http://www.rieselprime.de/Data/00300.htm"]here[/URL]. The ranges searched and primes found from this drive will be shown there.

Please report all reservations/statuses/completions for this drive in this thread. Please report all primes found in the 'Report top 5000 primes for k=1003-3000' thread. Please post all results files in this thread or send them to me at: gbarnes017 at gmail dot com.

Please report all top-5000 primes with a project ID of 'NPLB'.

[/code]There should be plenty of new top-5000 primes in this drive so let's roll! :smile:

[FONT=Verdana]Gary[/FONT]

Reserving n=500K-510K for port IB8000.

David, please post here when you have loaded the file. Thanks.

File loaded, server started.

There is now a ton of work to do on this drive. If anyone moved their machines away from port 8000 waiting on the sieving drive, feel free to move them all back here.

Once I get back, I'll probably put 4-5 quads on this drive so that we can make a little more serious move in the top-5000 standings.


Gary

do I smell a BBQ?

sniff...sniff...

[quote=AMDave;167746]do I smell a BBQ?

sniff...sniff...[/quote]

Funny you mention that. I just sent off a PM to several folks about a rally but it only allows one to send it to 5 people. I'll forward it to you now.


Gary

ah.... those Aussies and their barbies. :smile:

Drive#10 added to the Drive Progress chart: colour is Black

AMDave would it be possible for this chart

[url]http://stats.ironbits.net/statsnew/nplbstats.php?content=drive_progress[/url]

to be clickable so as it could be maximised? I find it a little hard to read and think if the chart was maximised and the left hand column removed it might be clearer.

What a cool idea.

I sometimes forget that I am now spoiled with a large wide-screen LCD.

I'll see what can be done :D

Reserving n=510K-520K for port 8000.

There are no more known (already found) primes from here up to n>520K so keep right on plowing for many NEW primes! :smile:


Gary

Reserving n=520K-560K for port 8000 with our nice new file sieved to P=20T.

This should keep it well stocked through the rally and then some. :smile:

David, the file has been sent.


Gary

Gary, the file has been loaded.

Results and primes up to n=520K have been verified against the usual places. No problems found.

Note to the admins:

I'm keeping a spreadsheet of all primes found since n=528K as per the Emails that are received from the servers due the speed at which they come in shortly before, during, and shortly after rallies. If any primes go more than a day without being reported, I'll Email or PM folks.

I'm reporting primes for LaurenU2 at top-5000; under his name of course. I'm not familiar with a couple of the ID's in the server. The possibility exists that we may need to report some primes for others or give them detailed instructions for doing so.

MrOzzy now has 2 primes that he needs to report. I PM'd and Emailed him with the 1st one that is now close to a day old. He should see the 2nd one and report them both since the regular notification Email went to him.

At the current rate, we'll likely past n=545K with the rally but I think people are still adding cores so we may be able to get close to n=550K! :smile:


Gary

Reserving n=560K-600K for port 8000.

Karsten,

Please process results to me for n=520K-540K for this drive. As of the close of today, all pairs for n<=540K should be in the server results.


Thanks,
Gary

David,

Later tonight, I'll take the factors from the sieve drive for P=20T-25T and apply them to that file. I'll then send you a file for n=600K-650K to load into port 8000. We're blowing through this drive at break-neck speed.

PCZ and Vaughan,

Could I talk you guys into moving most of your port 8000 machines over to Ironbit's ports 4000 (5th drive) and 5000 (6th drive) within the next 1-2 weeks? Within that time, we really need anywhere from about 5-10 quads running those instead of port 8000. It'd be good if about an equal # were on each port. I have 6 quads running port 5000 on the 6th drive but it is well behind the 5th and 7th drives. Ian has what appears to be about 4-5 quads running the 7th drive. With it ahead of the other 2 drives, we don't need any more on port GB4000 at this time. Only ports IB4000 and 5000 are lacking.

Several reasons:

1. Those drives will test a little faster at the same size for some n-ranges. You'll find slightly more primes per CPU hour at the same size.

2. There are slightly less already known primes on them.

3. The project intent is to keep the lower k's at deeper searched depths than higher k's for the above 2 reasons. I'd like to avoid a situation where k=1400-2000 is at n>650K and k=600-800 is at n<650K. Also, Benson's k=1005-1400 will not be at n=600K by the time we hit n=600K for k=1400-2000.

I don't want to inconvience the non-regular Free-DC searchers so I'm choosing to inconvience the regulars instead. :-)

Initially, the tests will take a little longer than port 8000 because the drives are at higher n-ranges but they won't be for much longer with so many cores on 8000. When all are testing the same size, the lower k-ranges should test faster for some n-ranges.

The next couple of rallies will be run on a combination of ports 4000/5000/8000 assuming that they are at close to the same search depth.

What an excellent situation to have to deal with! :-)


Gary

It sounds like your going to have to jump through some hoops Gary.
Free-DC is here to stay for the month of May.
In a few more days, there will be even more knpairs being consumed. :big grin:

Those are some hoops we don't mind jumping through. :smile:

Reserving n=600K-650K for port 8000. The file has been sent to David.

We're now using a file sieved to P=25T. :smile:

Lauren will suck port 8000 dry on his own :)

I will look at changing the ini files a bit later today.

I moved 12 cores from port 8000.

I put the I7s on ports 4000 or 5000 as their sieve jobs finished.

Current allocation
20 cores on 4000 (12 now, 8 more by tomorrow morning sometime)
24 cores on 5000
09 cores on 8000 - all 64bit Linux

OK, transition underway.

All results for n=520K-580K have now been processed. Results and primes have been checked against the usual places. No problems found. Excellent work everyone. For as quickly as we blew through this range and the large # of primes, it was a nice job keeping up with everything accurately.

Karsten, on your 10th drive page, you can complete the 557K-558K range.


Gary

All results for n=580K-600K have now been processed. Results and primes have been checked against the usual places. No problems found. :smile:

With the sieving drive now complete, I have now sent a file sieved to P=45T to David for n=630001-650000 for reloading into port 8000. This will involve stopping the server temporarily, deleting the current k/n pairs in that range at the end of the file, pasting the new pairs in at the end, and restarting the server.

I debated whether to go through with this hassle but ultimately felt it was worth it. It means that 4000+ composite k/n pairs will NOT have to be tested meaning that we should find primes around 2% faster than before when we get to that range, which should be in < 2 days. :smile:

Thanks to everyone for the excellent and fast job of sieving the range. Now, n=630K-1M will all test 2% faster, which amounts to nearly 75,000 k/n pairs that will not have to be tested! This will especially save a huge amount of testing time for n>900K, where tests will take, on average, more than twice as long as the current n=~625K range.


Gary

Done.

Karsten,

Can you process the results for n=600K-620K to me for this drive?


Thanks,
Gary

Reserving n=650K-680K for port 8000.

Results and primes for n=600K-650K for this drive have been verified against the usual places. No problems were found.

does anybody noticed this close high-n pair!?

1495*2^659159-1
1815*2^659158-1

it's a new highest difference-1 n-pair for all k < 2000 so far!

Primes and results for this drive for n=650K-660K have been verified against the usual places. No problems found.

To speed along the transition of servers from David's to my machines, I have asked him to remove all pairs for n>670K from his port 8000. So to make it official:

UNreserving n=670K-680K for port 8000.

Reserving 670K-675K for LLRnet G8000 (to replace IB8000 when it dries out in ~2 days).

Edit: I just realized that I don't have the master sieve file for this drive. Gary, could you send it to me? Thanks.

Just noticed your post!

Fortunately there are hundreds of primes at n=666666 that should slow top-5000 down a bit. I've moved some cores here anyway. :smile:

Whoops, seems I haven't yet sliced out a sieve file for n>700K on this drive (so neither Gary or I can send you your file just yet). I'll do that as soon as I get the chance and send you 700K-701K.

[QUOTE=nuggetprime;256681]I'd like something to test offline for my new cruncher,1K seems reasonable to start.
So I'm taking 700K-701K.

Please bear in mind that you will need to provide the results files when you are finished.

Reserving n=701K-710K for port 8000.

Reserving n=710K-720K for port 8000.

Reserving n=720K-730K for port 8000.

Reserving 730K-740K for port 8000.

Reserving n=740K-750K for port 8000.

Max,

When you get back, can you do a quick spot-check of the primes in [URL]http://www.noprimeleftbehind.net/llrnet/primes_8000.txt[/URL]. I'm seeing one or possibly two missing for n>735K.

I see four primes for n>735K, both in the primes_8000.txt file and in the database's list:

Your three primes are listed in the first post of this thread; Chris's isn't yet.

Everything looks fine to me, at least as far as I can tell from this end; the only way something could be missing is if you had additional primes which were logged directly on your clients and not on the server, in which case we have a different sort of problem.

Oh, that list must only update once per day. Can you verify that? I think I was confused because the pair counts and results update every hour (or every 15 mins). I say this because when I checked for the first 2 primes above several hours after they were found, they were not there.

Chris's prime is in the confirmed list. There are 3 new and 1 confirmed for n>735K shown in the 1st post at the moment of this posting.

Ah, okay, I too thought that the DB's Prime List page updated on an hourly basis with everything else. I learn something new every day. :smile:

Dave, could you please confirm whether this is indeed the case? Just to clarify, the page we are talking about is the one at [url]http://www.noprimeleftbehind.net/stats/index.php?content=prime_list[/url].

Thanks,
Max :smile:

HUH? No!! Why would you think that I was all of a sudden asking about he DB prime list? I've never seen an issue with that. I asked about how often the prime list that you created at [URL]http://www.noprimeleftbehind.net/llrnet/primes_8000.txt[/URL] is updated. See my original link.

Dave, no need to respond to Max's question.

That one should be updated every 15 minutes with the rest of the status page. Looking right now at the llrnet-status-pagegen.pl code (which generates that page and handles the primes_xxxx.txt files), I confirm that it does indeed append primes to the respective log files immediately after counting up the totals for how many results each user has submitted since the start of the day.

I'm not sure how anything could end up temporarily missing from that log, then show up later; the script runs every 15 minutes (more precisely, at :01, :15, :30, and :45 after the hour) and at that time adds any new primes to the log. Any further script runs that day will see that the prime is already present in the log and not add it again. The only possibility I can think of is that a prime was reported in the forum before the 15-minute page update caught it, that is, you spotted the prime directly in one of your clients' logs rather than seeing it first in the notification email.

The 2 primes were hours old. I should have cut-and-pasted it here along with the time that I got the Email for them. Oh well, all appears well. If it happens again, at least we'll have a history on it.

We have an excellent offer from Ian. He has agreed to put up to half of his cores on this drive in exchange for an exclusive reservation for him up to n=1M. This will help NPLB tremendously. What we will do is finish up port 8000 through n=750K and he will take it from there. It will then become a private drive for him similar to Peter Benson's k=1000-1400 effort at RPS.

In the next couple of days, I'll move all my cores here to get the drive finished up to n=750K.

Releasing n=700K-701K reserved and incompleted by Nuggetprime back in March. If anyone wants this range, please let us know and we'll send you the file. All that we would ask is that it be completed within about 2 weeks since the 5000th place prime is rapidly approaching that range.

At its current rate, port 8000 will dry out in about a week. If n=700K-701K is not reserved by then, I'll load it in there and we can all finish it up.

Reserving n=700K-701K for port 8000. This will be loaded in after the current n=740K-750K range, which will finish up by early Tuesday.

I will load n=700K-701K later today. With the current load of cores on port 8000, it should take about 2 days to complete.

Unusual find
 

Real unusual find within minutes of each other.

1775*2^982466-1
1775*2^982446-1

Same k, 20 apart on the n. Amazing for such a high n.
