when I click on the link
[URL]http://www.noprimeleftbehind.net/crus/[/URL]
I get an index page, with all the files in this directory. Think, this is not correct?[/quote]
Yeah, it seems Gary forgot to copy over the index.html file (since I put that one on there, and thus it wasn't in his reference copy of the pages on his hard drive). I'll do that in a minute.

Edit: done.

I've now finished updating the web pages as of this posting. Also updated were the 1k and untested Riesel and Sierp conjecture threads.

There was a huge amount of work done in the last 5 days reported both in the threads here and in Emails. If you can check your reservations, statuses, completions, and primes and let me know if their are any problems, that would be helpful.

Thanks.

I'd like to suggest that we take a complete break from new bases for at least a week now. We've garnered a tremendous amount of new information over the last 1-2 weeks.

I counted at least 30 new bases over about a 5 day span and many have complex algebraic factor situations that are taking an inordinate amount of time to properly analyze and add to the pages. After many hours last night, I still have at least 10 of them to add for the base 501-1024 thread and a few from the base 33-100 thread. I'd really like to get on to some other things like responding to my Email and PMs.

Let's work on finishing the new bases that we have already reserved and then extending already searched bases to deeper depths.


Thank you,
Gary

We're currently in the process of a server/web pages move to a new machine. The noprimeleftbehind pages, which contain the CRUS pages will be down for a little while.

The good news is that I've fully updated the pages for all work done through this posting. Once the pages come back up, they should be up to date.

Edit: They came back up but they're not up to date. It's still the "old" pages from a day ago. We're experiencing some difficulty with the port forwarding related to the move.


Gary

Change completed
URL tests for CRUS and NPLB appear to pass.
AMDave

I confirmed that all web pages were correct and updated as of about 8 AM CDT (1 PM GMT) today.

If anyone sees any reservations or ranges completed not properly reflected as of the above time, please let me know. I'm now working on just the few more that have come in since then.


Gary

OK, guys. Feel free to unload on me again to a certain extent. That is, go ahead and test some new bases if you'd like. I'd only ask that we stick to no more than 1-2 new bases per person per day. That will help me not get too far behind when stuff comes up in my personal/business life for several days.

The break from the web page updates helped me quite a bit in getting caught up here and with some other admin stuff at NPLB. Thanks for going easy on me for a few days.

It also gave me time to "mentally" generalize the "new" kind of algebraic factors across all bases so that won't take me so long to show on the pages now. Although I want to get it down "in writing" in the algebraic factors thread, the analysis to generalize it across all bases is quite involved so it may be several days or possibly weeks before I get to that. In the mean time if they aren't clear to you, feel free to ask Serge, Ian, or myself if you have a new base with k's remaining that you think could be removed.

In other news, late tonight, I'm going to start a recommended bases and efforts thread in an attempt to give a little more direction to the project so I know a little more of what to expect about what people are going to reserve or work on. There will be a mixture of new bases, 1k remaining bases, and bases that are somewhat behind their "neighbors (i.e. bases nearby with similar conjectured k)" as to how far they have been searched. That will help avoid some of the unexpected new bases load that seems to come around from time to time.

Thank you to everyone for your immense interest in the project. I'd much rather be too busy with it than not busy at all. It's certainly turned out to be far more interesting math-wise than I would have ever originally expected when the project started.


Gary

Hey all,

I'll be on a business trip from Apr. 20th (later today) to Apr. 29th. If everyone can please limit their new base reservations to one per day during this time, I'd appreciate it. I'll be especially busy this coming weekend.

To clarify: If you've already reserved the bases and they've been shown on the pages, post as many results/primes/k's remaining on multiple bases as you would like per day. Bases not already on the pages are what take a while.


Thanks,
Gary

NPLB rally
 

Hi all CRUS folks,

How'd you like a change from the conjectures for at least a couple of days? We'll be running an LLRnet rally at "No Prime Left Behind" (NPLB) from April 30th to May 2nd. See details at [URL]http://www.mersenneforum.org/showthread.php?t=13334[/URL].

For those who have never run an LLRnet rally, what we do is pile all of our machines on one server and see how many pairs we can process and primes we can find for 48 hours. We have both team and individual scores for pairs processed. Come join a team or be your own team. Either way, come join in the fun! :smile:

The tests will be at n=~765K-775K base 2 and should take ~10-11 mins. each on a modern machine.

Dropping bases > 512
 

After some contemplation today about what has transpired in the last few days/weeks/months on small-conjectured new bases and a PM that I received about someone wanting to do a large # of them on the Sierp side in the near future, I've decided to drop all bases > 512 from the CRUS project.

Don't worry, existing work will not be wasted and I'm not "cutting everyone off" at this moment in time. What I will do within the next 2-3 weeks starting in about 10 days is I will split up the web pages into bases <= 512 and > 512. If others wish to manage and update the pages for bases > 512, they are welcome to copy the pages to their own website and do so. I will be glad to assist in this process.

I also welcome someone creating a new project for bases > 512. For that matter, he can also extend it to as high of a base as he or everyone wants. Before doing that, obviously bases 250 to 512 will now have to be in one thread here with bases 513 to 1024 in another thread (vs. 250-500 & 501-1024). This will only amount to a little bit of tweaking and post moves. Then if someone wants to take bases > 512 into a different project or forum, we can get that thread moved to the new forum. (I guess I should have split them up in powers of 2 to begin with.)

I'm sorry but it's just become way too much for me to manage and it's taking too much time away from my personal and business life. When Robert posted all of the conjectures up to base 1024, a few people did some higher bases here and there and I was perfectly willing to accomodate those people and decided to extend the project definition to include bases up to 1024. But now that the new bases script has made it so easy to start new bases, I'm willing to admit that I've bitten off way more than I can chew from an administrative perspective. Also, admittedly, I've grown to dread the web page updates whereas previously, it was my favorite thing to do, mainly because removing the k's and adding bigger primes was fun, especially for the bases where a final large prime is found to prove them.

I had assumed that we would slowly work our way higher on the bases and I attempted to do that with the recommended bases/efforts thread, but it has gone largely ignored. For instance, at this time all bases <= 250 with a CK of < 10K are either at or nearly complete to n=25K. It is my thinking to keep slowly working our way higher on the bases in that manner...not just search only the small ones.

I will do what I can to keep up with what people post, including for bases > 512 until such a time that I get things split apart. I am still not willing to accept anything more than one new base per day while I'm out of town so please respect that. At this moment, I won't be able to make any updates until at least Monday.

I do appreciate everyone's enthusiasm for the project. I also appreciate people's offer to help with the HTML but ultimately, it's still too much to manage, because it's more than just updating the web pages. It's the checking, thread updates, asking for specifics when they aren't there, etc. Regardless, I'd much rather have it this way than the other way, with little to no activity.


Thank you,
Gary

I think it's not a good idea to split bases >512 into a new project or new thread here!

All information should be available at one location to minimize irritations wher to search for a special info or posting people in the wrong place!

Suggestion: Freeze all reservations for bases >512 for now and push bases with only searched to n=25k higher and so minimize the remaining pairs. Especially bases with only one k remaining should be done more than n=50k or 100k.

It should also be manageable to write a script to automate the html-code for a base given with files of primes and info like remaining pairs, level tested. But as you posted, the most work is to verify all those results.

I have to agree with Karsten. Just freeze any new bases work on anything > 512. Advancing bases already started shouldn't be a problem, I hope.
You can then adjust your upper limit as you see fit.

If someone wants to start a project for bases > 1024, then go ahead.

I have a few bases > 512 that I'm currently working on but will not start anymore. I still have quite a few cores doing bases < 512 and those will stay within that range. I do enjoy starting new bases, so I'll be working on the larger CK bases < 512 in the future.

Hope this helps. Ian

I'd be inclined to agree as well: freeze all reservations for new bases > 512, but keep the existing ones on the pages. Then, hopefully down the road when some sort of automation has been developed to make the process easier, we can reconsider opening them up again. In the meantime, though, there's no reason not to continue work on the already-started bases in that range, many of which have only one k remaining and which I'm guessing are not too hard to do updates for.

I agree that we should freeze any more reservations on bases > 512 but we still need to think more about this. The project is clearly too big as it is. It needs to be divided somehow perhaps into a subforum or something.

It kind of expanded itself with all of the conjectures posted by Robert up to base 1024. I went along with it by changing the project definition. I should have thought about the ramifications of that decision a little more.

Regardless, I have no intention of deleting the pages for bases > 512. That would be a travesty and unfair. I just feel that they need to be managed separately by someone else and I can give input if needed.

I wouldn't mind managing >512<1024. I'm not all that great at the math, if that matters, so there's apt to be some trials and tribulations. A sub-forum sounds okay. How would we handle the pages? I have a website but it's a free Google one and I don't know if it can handle the pages or not.

Gary, email me when you have time.

Agreed, a subforum sounds good--I recall that GIMPS did that for its LMH prefactoring efforts a while back (one forum for <79.3M, a subforum for everything above that) until they got their updated PrimeNet server that automatically handles the whole shebang, and that seemed to work well.

Regarding a website, I would suggest that we put them as a subdirectory under the existing CRUS pages.

Why split the project?
Why not just have someone else mod bases>500?

I need more time to think through all of the possibilities here. In the mean time, let's please go ahead and freeze reservations on NEW bases > 512.

If you've already reserved a base > 512 or are extending an already-searched range (a.k.a. the 1k thread), then that is perfectly fine.

One possibility that I thought of today is to freeze reservations on bases > 512 until May 15th or 31st and then after that limit new bases > 512 to one per person per week but that still doesn't really fully fix the problem. As much as it sounds like the opposite, I don't really like to "restrict" people's work on things. What would be better is to have another admin that can check multitudes of new bases that come in and subsequently update the pages.

Thanks for the offer Ian. What would work better than you keeping them updated and hosting them on googlepages is to go ahead and keep them updated but then send them to me to upload to noprimeleftbehind. The link is just easier to remember and sounds better. Another option would be to have Max give you access to SCP stuff to my server machine. Then you could upload stuff yourself to the noprimeleftbehind pages.

Either way, we could create a subforum or just leave the threads as is with slight tweaking to the ranges from 250-500/501-1024 to 250-512/513-1024 and subsequent split/move of a few posts.

This is not set in stone right now. I'm just thinking out loud at the moment.

I finally have some time to start updating the pages again so am going to work on what I can finish in an hour or so right now. Coordinating the rally at NPLB and answering Emails about it has taken a fair amount of my time away from updating the pages here.



Gary

I've now fully updated the CRUS pages for bases <= 512 and quite a few bases > 512 after nearly a week hiatus. There are probably 5-6 posts left for bases > 512.

If everyone can check their statuses, k's remaining, etc. on their recently completed or ongoing reservations, that would be helpful. Also helpful is would be to check the 1k and untested bases threads. It was an unusually large batch of updates. I hope to finish the bases > 512 up late today. (Monday)


Gary

Hi all,

After some discussion by Email with Ian (MyDogBuster), I've come up with what I believe will be a good viable alternative for the project so that people will be more free to search new bases and the project will not have to change in any marked way. l will state it in generalities first and then the details. People who are not searching new bases can feel free to ignore the details because there is little change to already-searched bases.

The generalities: Ian has now become a project co-admin, the project is opening back up for all bases 2 to 1024, bases with conjectured k (CK) <= 200 will be administered by Ian, we'd like to ask that all NEW bases with CK <= 200 that people have already done but have not reported be posted right away, and the limit on new bases with a CK > 200 will be increased to 2 per day.

Details:
1. The project is now open again for bases up to 1024. Feel free to work on any unreserved base that you want to, new or not.

2. For NEW bases with a CK <= 200, please use these guidelines:
a. Feel free to post as many as you want at any time in a single posting to save space. Ian has agreed that he can handle a virtually unlimited # of new bases because they will run out eventually.
b. If posting more than 1 new base, do not include details about specific primes or the specific k's that are remaining. Only state the base, CK, search limit (if applicable), and [B]number[/B] of k's remaining -or- that the base was proven, one base per line. The 1 base per line will make it easy to check and strike off bases completed. The fewer postings the better. Mark, this means if you have 60 new bases to report, you can put them all in one posting and post a file that includes them all. If posting only 1 new base with < ~50 primes, you can include the details shown in c. below directly in the post without a file.
c. For the details, please post a file that includes the CK, MOB, primes, trivial k's and k's remaining. If the file is too big, please Email them to Ian and copy me in on it.

3. IMPORTANT: When posting a load of new bases, please split them up into the various base threads if necessary. If you are posting 20 bases and 5 of them are for bases 250-500 and 15 of them are for bases 501-1024, you'll need to post them in 2 places. The main reason for dividing up the reservations threads was so that we could trace back if there is a problem on a base and to make sure we haven't missed anything on the pages. If base 350 winds up in the bases 501-1024 thread, it will be difficult to find.

4. For NEW bases with a CK > 200, please use these guidelines:
a. No more than 2 reservations per day. Since this has been a source of confusion in the past, here is how a reservation is defined: Any time that you either reserve a base or post it's primes/k's remaining for the very first time, it is a reservation. In other words, the base is not currently shown at all on the web pages. Also, averages don't count. Please do not wait 3 days and then post 6 reservations. The limit is on a per day basis. I will be administering these bases.
b. If finishing up a grouping of new bases, you can post 3 in a day but please limit those if at all possible.
c. Like we do currently, go ahead and provide details or a file of the CK, MOB, primes, and k's remaining (or that it is proven). Once again, trivial k's are not needed. The CK helps us because we can then more quickly strike it off the untested bases thread.

The only real change for new bases with CK > 200 is the limit per person per day increase.

5. For existing or already-searched (old) bases, no change. Continue as usual. We did not previously restrict already-searched bases to b<=512. You can reserve and post statuses on as many bases as you can reasonably manage because they are already on the pages.

6. Please attempt to post a status on all reservations at least once every 2 months. We have several right now that are > 3 months; a couple of them > 6 months. It helps us if we know these bases have not been forgotten.

The bottom line is that the only restriction that we now have is on new bases with a CK>200. Everything else is open for business. :-)

If Ian or I find that a "new" base has already been done, we will respond accordingly. Before posting a load of new bases, please check the web pages and recent reservations to avoid duplication, both in searching and administering.

Ian has agreed to do the following for new bases with CK<=200 in approximately this order:
1. Follow up on anything that looks like a duplication or is erroneous in some way.
2. Remove the bases from the untested bases thread.
3. Add the bases with 1 k remaining to the appropriate thread and calculate the weight.
4. Create the HTML for the new bases. I will review or complete algebraic factorizations and GFNs without a prime.

I will of course do the same for new bases with CK>200.

I'll still reserve the right to restrict new bases with CK>200 to 1 per person per day while out of town on business. On average, that is only about 7-9 days out of every 4-6 weeks.

It is my hope that this will prove to make the project fun again for all including the admins. I'm sorry we had to restrict it for an extended period but it was necessary for my own sanity until a viable alternative could be thought out. :smile: Thank you for your patience.


Gary

Just my two cents worth.

After you post the one-liners, I will attempt to determine viability and correctness and keep the untested conjecture threads up to date. That thread should be the "authority" on what has and has not been started. This is because it will still take some time to get the HTML's created and forwarded to Gary. I would check the pages if working on CK's > 200 although the untested thread should also be up to date.

If for some reason there is a problem with the details that are submitted, I will notify you by PM or email (if I have it on file) to help straighten it out. The method I use on a new base is that for an even numbered base I subtract 2 from the CK. That is the number of k's I have to account for. For an odd numbered base I subtract 2 then divide that by 2 (even n's not tested). I am not going to assume that because you furnish me with the primes and remaining k's that everything has been accounted for. I need the # of trivial k's and MOB's also. That is the only way I can be sure everything is accounted for. I will need a file or list on primes found, remaining k's (if any)and MOB's (if any).

The HTML's will be created and forwarded when I have time and I feel that Gary won't be overloaded. We should be able to work our way out of this backlog and move the project forward.

Again, please be sure that your posts for each base are in the correct thread.

Thanks Ian

Completely agreed. The untested bases thread should be immediately updated as the 1st priority to avoid duplication of work. For clarity, I reversed the sequence of them in the original post.

Ian, if you have time, you might see if you can visually or in some other automated fashion, check the untested bases threads vs. what is on the pages right now. Whatever is in those threads should not be on the pages EXCEPT if the pages show "no testing done". The quickest way that I'm aware of is to cut-paste the threads into a spreadsheet column A and sort them by base. Then, if you're fairly fast at keying, just simply key whatever bases are on the web pages into column B; being sure to go back and remove the bases that show "no testing done". Then, paste all of column B directly below column A and sort the entire mass of them by base. You should have one occurrence for every base. If there is a duplicate, then it either needs to be removed from the untested thread, you mis-keyed something, or you forgot to remove one that showed "no testing done" on the pages; usually the former of the 3. If one is missing, if you haven't mis-keyed something, likely it means that I removed the incorrect base from one of the threads at some point and it will need to be re-added.

This took me about an hour combined for everything on both Riesel and Sierp previously (last time I did it was ~6 weeks ago) although will likely take a little longer now since so many more bases are on the pages now. It's a nuisance but is needed every once in a while to guarantee the thread's accuracy.

It's probably best to do it now before the load of new bases start coming in.


Gary

I'll do a complete audit of those threads shortly (in the AM). I'll just print off the thread and do a manual check against that.

I guess there is not a better time to start this than now. I believe there are 4 bases currently reported out there in the threads that were posted in the last few days that are <= CK 200. I'll take them and anything from this point on.

Edit: Gary, I will start with R275, R290, R623 and S263.

Excellent. Thanks for doing the audit. Yeah, I was going to get to updating the pages early afternoon Monday but I'm quite happy if you'll start doing the CK<= 200 bases right away. I know there are some general updates (like for S6) so I'll do those tonight before bed. It's a good idea if I see we're on the same page on the HTML before you have to send me a load of them.

BTW, as further clarification in this transition phase: If they were previously reserved and already on the pages like you report yours, then I'll take care of them. They would already be removed from the untested thread.

[QUOTE] It's a good idea if I see we're on the same page on the HTML before you have to send me a load of them.
[/QUOTE]

I'll send to one sometime today (later). I'll be doing the main page and the reservation page on all.

Sounds like a plan, guys. Just one quick question though: for bases [i]originally[/i] with a CK <=200 that have already been searched to n=25K or so (for example, the various bases with 1 k remaining), whose "half" of the project do those fit within? That is, do I need to send results for those to Ian or Gary? (I know, it would probably be best to copy both in for all but I figured I should check anyway.)

I'm not doing the base I'm doing the HTML's for the conjecture pages. Those were the bases turned in I'm starting with.

10metreh,

Upon your entry into the new bases of the project, you've caught us in a bit of an administrative transition phase. Don't worry, Ian is not taking anyone's reserved work or duplicating other's work. He will just be taking care of part of the behind-the-scenes administrative work when people report statuses on small-conjectured new bases related to HTML creation and various thread updates.

To clarify for everyone, Ian will only be administering the bases that have both of the following conditions:
1. Have a conjectured k (CK) of <= 200.
2. Are not already shown on the pages.

As for #2, if they are not already shown on the pages, we refer to them as "new" bases.

It is the above types of bases that are completed by people the most quickly because many are easily proven. Because of that, they can be reported in such large quantities at times that I could not keep up with them. Therefore, I previously had to severly restrict their reporting. Now there is no restriction on them.

The only restriction now is on "new" bases with a CK of > 200 at 2 per person per day.

It is my/our hope that this will eventually allow about 60-70% of all bases <= 1024 to be tested and shown on the pages in a more resonable timeframe and with less posting by everyone as well as allow the admins to keep their heads above water on everything.

Actually, no you aren't kidding. :smile:

Yes, you can submit 200 bases at once BUT they all have to have a CK <= 200. They also need to be split up into the appropriate base 100-250, 251-500 and 501-1024 threads. So if you wanna submit a bunch at once, ya gotta do a little bit of work to do so. :-)

To take it a step further, we want people to go ahead and innundate us with new bases with a CK <= 200 immediately so that others don't duplicate the work in the meantime. Ian will manage the load and will coordinate with me on slowly reducing the backlog. The managing of a large backlog is something that I felt I could not do on my own.

We are asking that a minimum of detail be shown in the posts. One base per line showing the base, CK, search limit, and # of k's remaining (or that it is proven). The detail can be in an attached file. To save yourself and us time, we don't need GFNs or trivial k's. Just primes and k's remaining if applicable are all that is needed in the attached file (or Emailed to us).

To take it a step further, we want people to go ahead and innundate us with new bases with a CK <= 200 immediately so that others don't duplicate the work in the meantime. Ian will manage the load and will coordinate with me on slowly reducing the backlog. The managing of a large backlog is something that I felt I could not do on my own.

We are asking that a minimum of detail be shown in the posts. One base per line showing the base, CK, search limit, and # of k's remaining (or that it is proven). The detail can be in an attached file. To save yourself and us time, we don't need GFNs or trivial k's. Just primes and k's remaining if applicable are all that is needed in the attached file (or Emailed to us).[/QUOTE]

As everyone here has noticed, I have taken a break from the project (except for managing S63). I have submitted many results that you had rejected before this recent change in how the project is managed. I don't know the status of those.

Huh? I never rejected anything of yours that you actually posted. If you posted or sent them, they are on the pages. I have rejected the IDEA of you sending multitudes of results or postings to me at once. Even KEP's load of Sierp k=8 conjectures that were posted all at once eventually made it on to the pages, 2 a day for an extended period.

So...are you planning to send the results of your 60 proven bases that were not previously sent that I previously objected to you sending? Just curious. It would help Ian to have a general idea of what is coming his way. I had anticipated that you would want to forward them right away. But that is your choice.


Gary

After some discussions with Gary, we have decided that if you have a trivial factor file created by the script, then it is okay to include it in the files sent in. I need at least the number of them at a minimum. This helps me in determining if all k's are accounted for. No need to go back and get them on bases already submitted, but it would be nice on future postings.

I can, but I have not been paying much attention to what has been submitted. I'll look at the "untested" threads, pare down my lists, then send him what I have

I will be out of town on a camping/canoe trip from Monday until very late Friday. I will not be on the internet during that time and will be back on Saturday afternoon.

Find lots of primes while I am gone!

Have fun :smile:

By the way: I am still alive ;) but my machines are on summer break at the moment.. It's just too warm in here, so I don't need a electric heating right now, sorry.

With a large portion of bases with CK<=200 now tested, Ian will now be administering all bases with CK<=500. This means creating and sending HTML to me as well as updating the applicable threads.

At the moment, my main host machine for servers and the web pages is down. I'm looking into the problem. I'll probably have to swap its hard drive with another machine. I'll let you know when and if the server/pages are back up.

The servers and web pages are back up now. A swap of the hard drive with another machine did the trick. :smile: Now the trick is getting the "correct" server/web page machine working again. :yucky:

The server machine that hosts the noprimeleftbehind pages is inaccessible right now. It may be the better part of a day before the issue is resolved.

As frustrating as it may be for some of you to not be able to access the CRUS pages, please rest assured that I am keeping them up to date with various statuses from the threads, PMs, and Emails on my machine as they come in. This way, when we get the problem resolved with the IP address, they will be immediately uploaded and up to date without me having to spend several hours bringing them up to date.

If you have any questions about the status of a base that you were thinking about doing, please ask in the applicable reservation thread.

Once again, sorry about the problem.

Gary[/QUOTE]
Also: as over at NPLB, you can work around the issue (DNS problems) by replacing noprimeleftbehind.net in the URL with our old domain, nplb-gb1.no-ip.org. The CRUS pages can thus all be reached at:

[url]http://nplb-gb1.no-ip.org/crus/[/url]

Some of the links on the pages Gary maintains (the reservations and conjecture info pages) won't work because they are absolute instead of relative links, but you can still get to them by pasting the link into the address bar of your browser and fixing the respective portion.

I am happy to report that the CRUS pages are now back up.

After accessing a page for the first time again, you may need to hit refresh on your browser to bring up its new version.

I will be out of town on vacation to the southwest from Weds June 15th thru Fri June 24th. I will only be on the internet once or twice during the entire trip and will update the "easy" stuff on the pages as I see fit. The more difficult stuff will have to wait until I get back.

Find lots of primes and prove many conjectures while I am gone!

I have been following up on reservations that are more than 2-3 months old so several of you will have PMs from me.

It is requested that everyone please provide a status on any outstanding reservations that have gone more than 3 months without an update. Huge reservations such as for conjectures > 100000 with 100s or 1000s of k's remaining can go longer but it is preferred that statuses still be provided at least every 6 months on those.

Thanks!


Gary

It appears that our bases 101-250 thread has disappeared. I certainly didn't unsticky or delete it. I have a PM into Mike (xyzzy) about the problem.

In the mean time, if you have a reservation or status in that range of bases, please reported it in the bases 251-500 thread and I will move it over after the missing thread has (hopefully) reappeared.

Very odd. I had posted to it a few hours ago with some results.

I don't even know how to delete a thread, so I'm innocent (I hope).

[QUOTE=rogue;267199]Very odd. I had posted to it a few hours ago with some results.[/QUOTE]

I was splitting that post up (since it had a base 101-250 along with bases 251-500) by copying it over to the bases 251-500 thread when the bases 101-250 thread just disappeared. Fortunately I got your post copied along with the results before it deleted itself.

Mike has been unable to help. He sent me a bunch of logs but they don't tell me anything.

I guess it is gone and although I usually pull the results off right away, if people have cut-pasted primes into a post, I don't necessarily put those in a file on my machine so there could be some lost data.

I guess I'll start a new one with my own recent reservation.

I'm now concerned about the stability of things here.

Aren't there any backups to restore at least the better part of the thread?

[QUOTE=Puzzle-Peter;267223]Aren't there any backups to restore at least the better part of the thread?[/QUOTE]

I have sent an inquiry about that.

[QUOTE=gd_barnes;267226]I have sent an inquiry about that.[/QUOTE]

There is no easy way to recover the thread. Backups are only made once/month and it's not easy to pick out individual threads.

Although I never received a screen that asked if I wanted to delete anything, Mike says that there was a "soft deletion" request that was executed by me and then the "housekeeping process" deleted it. This must have occurred almost instantly after I copied Mark's post because I almost immediately could not find the thread.

Personally I'm very confused why a soft deletion would be acted upon immediately by any housekeeping process, especially one where it was a huge thread of posts.

Edit: For historical reference, the URL of the deleted thread is [URL]http://www.mersenneforum.org/showthread.php?t=12992[/URL]. Perhaps that will help with any recovery in the future.

Great. I'm not sure how you did that though. I tried googling "Bases 101-250" and just got the original URL that I put in my last post. I'm also not sure how to copy it all over here. It certainly can't be cut-pasted. I'd be perfectly happy with a thread through July 10th and updating it with the most recent posts. That would only be a loss of about 10 days data, which is likely only to be 5 or 6 posts during that time.

I wonder if Mike (xyzzy) could/would take your July 10th link and copy it all over here.

Edit: I also wasn't able to figure out how to get page 29, 28, etc. I tried changing the URL in the cache where there was a "30" and that didn't work. I also tried clicking on page 29, 28, etc. on cached page 30 and that didn't work. I'm completely unfamiliar with this cacheing process at Google.

Thanks!

I managed to save them all off to my computer just now--all except pages 1, 12, and 29, which are for whatever reason missing from Google's index. Some of those may be able to be filled in from the Internet Archive (the other link Tim gave).

Based on what I picked up of the inner workings of vBulletin forums from the erstwhile noprimeleftbehind.net forum, it would unfortunately not be possible to re-import the cached data into the mersenneforum--not without creating a new thread and manually re-posting each message (by copying and pasting the text from the archive). What might be a better solution is for me to take the archive pages that I saved off and upload them to the noprimeleftbehind.net/crus site--we could then put a link to the backed-up copy in the first post of this thread, instructing readers to head there for prior posts.

I'll see if I can get that rigged up ASAP--I saved the pages off just now in .mht format, which keeps them nicely self-contained into a single file for each page, but may not be viewable in all browsers (they work in IE and Opera, but not anything else AFAIK). I may be able, however, to get them converted somehow to .html format so that they're universally viewable.

Sounds great to me Max.

We have been evaluating this issue deeply and we think we know what happened. It is pretty complicated and we barely understand it, so typing it all out would be pointless. Gary has our phone number and he is welcome to call and we can try to explain what happened and how to avoid it in the future.

We hope this abnormal event has not soured you all against the forum.

:sad:

I had a long phone conversation with Mike about the situation. With some work, we could probably recover the entire thread up through July 1st and then using cached pages as previously discussed, we could bring it up to date through about a week ago. At this point, I believe what Max is working on should be sufficient for our needs. The bottom line is that we will upload what he has (which appears to be everything minus about 3 pages out of 800+ posts through about a week ago) to the noprimeleftbehind pages and provide a link to it in the first post of the new bases 101-250 thread.

Mike was forthright and apologetic about the situation. Without going into great detail, it appeared related to the system somehow interpreting that I wanted to delete the first post in a thread (I was actually copying the last post in a thread), which can cause a soft delete of the entire thread. Unfortunately just a few seconds after that happened, a supermod just happened to be running a housekeeping process that permanently deletes any soft deleted threads. The chances of such a thing happening are very slim.

My work load
 

Due to health reasons, I'm cutting back on my CRUS work.

I will not be testing anything over n=100K (it's to much to manage and very boring).

I will instead concentrate on stuff < n=100K and bases < 300. I will be doing very long reservations. I still will have about 40 cores available so I'm asking for suggestions.

I will be canceling some reservations.

It seems that somehow the No-IP clients I set up on Gary's machines have stopped sending updates sometime within the last month. They should have been updating every couple of minutes (a precaution left over from when Gary still had a dynamic IP), but they have apparently not done so in over 30 days, which for a free No-IP account causes the host to be placed on "inactive" status pending deletion.

I logged in just now to No-IP and performed an update manually. We'll be good now for another 30 days, in which I'll see to getting Gary's machines back to performing the updates automatically like they used to.

Just to clarify for everyone: this does [B]not[/B] affect the noprimeleftbehind.net domain, just the older nplb-gb1.no-ip.org which we've retained for backup. A number of our members were using this address in their clients, so that their clients could still connect if Gary's IP address changes (which happens infrequently with his business class service, but did happen once a couple of months back). Ironically, though, the very reason this issue occurred today would have also made this protection moot. :rolleyes: As soon as I get the chance I'll make sure the No-IP clients are up and running on at least some of Gary's machines so that this doesn't happen again.

Hurricane Irene
 

Seems like my house is in the cross-hairs of a massive hurricane. We are forecasted to have 100 mph winds and torrential rain. Seeing as my power usually goes out when someone sneezes in the neighborhood, I think I can expect to be without power for sometime. I'm really looking forward to Saturday and Sunday. Stay dry everyone.:grin:

Gary, Looks like Atlantic City got hit pretty hard with rain and winds. The eye of the storm passed within a few miles of AC. Good thing they kicked you out. LOL

The CRUS server will be down for 10-15 minutes while I apply some updates and do some other maintenance.

Moved the conversation about sending large files around to the bases 33-100 thread.

A note for everyone: Ian has been providing many files sieved to P=1T for n=25K-100K for misc. bases with about 4 to 8 k's remaining at n=25K. There are links to all of them on the reservations pages.

The noprimeleftbehind server/pages are down and probably will be until late Friday when I get back from out of town to check the machine.

Servers back up thanks to Tammy (Gary's GF) :busy:

Unfortunately the main CRUS server machine is down so neither the web pages nor the PRPnet port are available. See details [URL="http://www.mersenneforum.org/showpost.php?p=305082&postcount=127"]here[/URL] and [URL="http://www.mersenneforum.org/showpost.php?p=305088&postcount=128"]here[/URL].

Sorry about the problems.

The servers and web pages are back up. It is still unclear what caused the machine to shut down. I'll keep monitoring it on and off as the night goes along.

I'll have some updates for the pages later tonight or on Saturday.

Once again, sorry for the interruption.

After a 3 week long hiatus from updating the web pages, they are now fully updated. There were a tremendous number of updates and file links to add. Please check any recent statuses and files sent to me to make sure that they are reflected in the latest updates.

Just for info.

In a week or two. I have the file here I only have to load it :smile:


Lennart

It appears that my IP address has changed and it has caused the noprimeleftbehind pages to be inaccessible even though the server machine is working correctly. I am unfamiliar with how to correct this. I've sent an emergency Email to Max.

In the mean time, you can access the pages with, i.e. [URL]http://nplb-gb1.no-ip.org/crus/Riesel-conjectures.htm[/URL] or to access the server stats page it would be [URL]http://nplb-gb1.no-ip.org:1400/all.html[/URL] or to access the servers themselves with your clients, you can change your prpnet.ini file to [URL]http://nplb-gb1.no-ip.org:1400[/URL].

Sorry about the problems. I'll post here as soon as I hear something from Max.

The IP address has been corrected. All of the servers and pages should be working now. If not, you might have to wait an hour or two because sometimes it takes an hour or two to propogate the changes throughout all of cyberspace.

With help from AMDave, I was able to understand how to fix this problem if it happens again in the future. I also have given him my UserID and password at the EasyDNS domain site. Now there are two of us that can fix the issue. Since he's almost halfway across the world from me, hopefully we should have the better part of each day covered and so we should be able to get it fixed fairly quickly in the future.

Edit: I just noticed that the stats pages are mostly blank. This is because at the last hourly update, the scripts that accessed the main pages could not do so due to the issue above. At the next hourly update at 16:30 CST (22:30 GMT), they should be correct.

On Tuesday morning, I will be headed out of town for 8 days. It is possible that I will not have internet access for that time. If so, I'll update everything when I get back.

Major re-cycle has been completed. Everything seems to be running smoothly now.

Lennart

All,

The bad sieve file for S35 as stated [URL="http://www.mersenneforum.org/showpost.php?p=326274&postcount=1106"]here[/URL], most likely came from a bad version of srsieve (v 0.7.0). These problems are gone in more recent versions.

Please ensure you do not have this older version when conducting sieving.

Thanks for posting that Mathew.

In case people missed the discussion, our PRPnet port 1400, which was previously running our 51 bases drive, is now running Sierp base 6 for n=700K to 1M. Come join the fun and find some huge primes! :smile:

Kenneth (KEP) came with an excellent way to send me a huge file. He used "Google Drive". The file that he sent me was all of the primes, k's remaining, etc. for his R3 reservation for k=11G-12G to n=25K. It was over 840 MB compressed. I was able to download it in 5-10 mins. with no ads, no size restrictions, no # of download limits in a day, i.e. none of the hassles of sendspace. :smile:

If you are sending me files for any new reservation (i.e. n=1 to xxx) with a huge number of primes for bases 3, 7, or 15, and the file is larger than Google's 25 MB Email limit, I would suggest Google Drive.


Gary

Yeah, Google Drive is very good for that - it's basically a cloud storage service similar to Dropbox, Microsoft SkyDrive, Box.com, etc. (if others are familiar with those). Generally they're intended for personal storage of files and synchronization across multiple devices; but they usually offer a "share link" option, which is what KEP used to send Gary his large file.

A similar solution I've seen a lot of people use here is to post files on a personal web space they own. I've used the noprimeleftbehind.net web site for this a couple of times in the past. Services like Google Drive and Dropbox basically just automate this in a nice user-friendly system (plus of course they're paying for the hosting).

I would note that with these services you do have a finite amount of space - so, if you're using it to transfer large files, you'll eventually need to go in and delete the files manually to free up room for future uploads. Just make sure you leave it up long enough for the person on the other end to download it - kind of similar to how Sendspace puts things up for 30 days. :smile:

I have just completed a large update to the pages. You might check all of your statuses and reservations since about Nov. 1st to see if I missed anything.
