I do not see for a thread for this BOINC project here and I do not see it as a list of projects being kept track of. Even though it is still under development, it still has plenty of work and it is stable. It is kind of like Chess@Home but with a lot of work.

Here is the website http://nqueens.ing.udec.cl/ hopefully it is up to the muster of being added to the vault. Hopefully a thread like this does not exist yet or else it makes me look like an idiot.

Yes NQueens has been posted about but not in it's own http://www.team-ninja.com/vbulletin/showthread.php?t=41139


So tells us about it....

Maybe we can get some more people posting thoughts about this project

Project seems to be stable and have plenty of work.

[BlisteringSheep]

I agree. The project seems to be stable, and I've never had problem getting work. The WUs are nice and short, too. Credit isn't instant (requires two concurring results), but still doesn't take too long because of the relatively quick turnarounds. The current board (board size 25) they're working on is 11.4% done, with 1,228,403 WUs left. Board sizes 19-24 have completed already. Board size 25 is the largest with a known result to validate against - there aren't any currently published plans (that I know of) to continue to board size 26.

Clients are available for Win32, Linux x86 and Linux x86-64.

I have been running nqueens on a windows 2000 dual core machine and a linux 64 dual core machine for several days and have experienced no issues.

My only concern would be the longevity of the project and would suggest the project team be asked if there are any plans past board size 25. The project did shut down once after completing 25 and is re-running it to verify.

[BlisteringSheep]

I agree with the concerns, but just a note that I believe the re-run was for board 24.

Also, in the couple of days since my last post, the WUs have gone to 12.2% done, 1,217,301 WU left.

It would be nice to hear, though, if there are plans beyond board 25. As fractal says, if they are planning at stopping at board 25, it probably wouldn't make sense to add them to the vault.

[umccullough]

Aye!

Would be disappointing to get this into the Vault only to have the WU consumption increase and run it out of work in a few months.

[Wabbit98]

I remember reading on the forum they might have a plan to go beyond board 25, but that they might have to redo some of the WU's as the boards get larger in size.

This project will be running the N=26 board, but there may be a brief pause between 25 and 26 to upgrade databases. See this thread from the project:
http://nqueens.ing.udec.cl/forum_thread.php?id=59

I haven't run this one personally, but teammates have had no problems with this project. Sounds like a keeper.

[russkris]

Whats the work flow like?
How long do they think it will last>?

[KAMCOBILL]

Work flow is great. As for how long it's hard to tell, but it was first mentioned more than 5 months ago.

Edited: Has to be better than TSP:D

[mewbysea]

They've completed the N25 run and any re-issues, still have about 8500 wu's being crunched.

NQueens plans an N26 run but needs to take the servers down for a bit first.

No word yet on the timeline. (Info from project admin's 18 June post. (http://nqueens.ing.udec.cl/forum_thread.php?id=62))

[fractal]

+++ what mewbysea said. Most of us have been waiting to see if they can actually scale to N26. If so, then it would be an excellent project. If not, well, it would be a real shame for it to be yet still another APS / TSP / ...

[mewbysea]

NQueens is back up and running, over 1.750 million wu's to crunch! :cool:

[russkris]

really... thanks for letting me know..

Time to think about this project then

[fractal]

Looks good to me.

[KAMCOBILL]

Bump, Ditto.

[russkris]

Adding very soon

[Beyond (Ars)]

Wouldn't this be a good candidate for the Misc Category? Sure it uses math to compute the problem but so does EVERY other project.
We're way too light in the Misc and this seems like a fitting addition.

I don't agree. I think adding a project to the misc category just because it is "light" is wrong. This is a typical mathematical problem and should be added to the math category. :)

[Beyond (Ars)]

As 1fast6 said in the New Projects thread:

I also think the logic/puzzle based projects, such as Sudoku, Nqueens, Chess960, etc, should be added to the Misc group, not the matematical group...

It's NOT just adding the projects to Misc because it's light (although it is), it's taking them out of an inappropriate category. These game projects have no more business in the Math category then projects like Spinhenge, Folding, Cosmology or Proteins. Everything is a math problem but these are not pure math problems such as PrimeGrid, ABC, SOB, OGR-25 etc. Why not just dump everything in the Math category then?

[leavitron]

I'm with Beyond here...

If it isn't pure math, if it isn't proving a mathematical formula then it should be in Misc. Primes are math. ABC is math. This is not.

[russkris]

Yeah OK..

I have asked nano to change to from Math to Misc

[lechumbl]

Hi Rusty,

Folks sure seems to get more rude these days in here, huh?

You need to have a class on forum politeness.

Take care.........

[opyrt]

Well, in that case, SZTAKI Desktop Grid (random purpose), SETI@Home (analysing radio signals... not very related to physics) and SHA-1 Collision Graz (decrypting) should also be moved to the Misc section, and we would soon end up with the Misc section being the biggest one. :rolleyes:

I would say that the N Queens project is a "mathematical puzzle" so why not keep it in the maths category instead of clogging up the misc category? :)

[leavitron]

Yeah OK..
Forgive my ignorance here Russ, I don't know if I should take this as sarcasm or frustration.

I post here for one reason and one reason only - because you ask for feedback on projects and input on their inclusion in the Vault or not. This is not my "home." I typically only wander in once a month or less. If you don't want our input, then why would ask for it? More to the point, why would you get frustrated when we give it?

We're only trying to help. If I come across as upset or overbearing, it is not intended. I lack the social graces to recognize certain situations for what they are.

When the 'ol man speaks...
Some of us plug our ears!!!

This has nothing to do with manners. Russ asked for input. Now you guys are scolding us for providing it. Just exactly how is that supposed to work!?! :rolleyes:


And for the record this has absolutely nothing to do with advancing Ars in the Vault. We already are first in the Vault. And we have a commanding lead in Math. So we don't care about that. We only care about honest and fair representation in the Vault. And we don't feel that the current placement of the new projects represents a reasonable balance.

I found this in a forum somewhere:

We can hope more new M-12 teams, than yoyo teams, come along to put us back at #1.Wouldn't this be a good candidate for the Misc Category? Sure it uses math to compute the problem but so does EVERY other project.We're way too light in the Misc and this seems like a fitting addition.Congrats with 1. place in misc tomorrow:thumbsup:

[lechumbl]

Hi,

It has nothing to do with providing input.
It is the rude way you did it.
You come on here with a few posts and try and tell Rusty and such how to run their site.

Input is one thing, yours is another.

Rusty is too polite to say something, I am NOT.

Take care......

[Beyond (Ars)]

I think maybe some are getting a bit touchy. I can't see that anyone meant to be rude. Seems this is a forum for discussing the Vault. I think that's what's happening? Anyway hope there's no hard feelings and thanks for listening, Rusty. The DC-Vault is well done, much fun and provides a nice service for smaller projects. It's impressive. It seems you only hear from most of us when we want something changed. I'd say it's quite a compliment that you don't hear too often :-) Thanks again! Beyond

[leavitron]

Ungelovende - I'm guessing that you got that quote from the Ars DCA somewhere. However, I am certain that I didn't say it and I doubt that either Beyond or Fractal said it. Therefore, I don't think it is relevant to the motivation of any of the 3 of us who have posted here. I know for sure it's not relevant to me. I honestly had never seen those words posted before. And I am not worried about diluting the Misc category. You guys are first because you have earned it. I would still be saying to put these in Misc even if it put Ars in 20th place in Misc. I wouldn't care. I do things because they are the right thing to do, regardless of the personal consequences. I guess I just got a little too caught up in wanting everyone else to see things my way.

Lechumbl - I am sorry but I don't see how expessing my opinion that two projects have been miscategorized counts as telling an Admin how to run his site. If I was in his face constantly, day in and day out, criticizing every move he made then you would have a case. But two projects out of the 41 that are in the Vault? That's not even 5%. I apologize if the "enthusiasm" of my post offended you. It was not my intent.

[Xaverius]

Okay guys, perhaps now is a good time to enjoy a good cup of coffee (It's 9am over here). Maybe it is because I'm from Holland and we're supposed to be pretty straightforward but I can't find a wrong word in the posts. Perhaps a bit too harsh.

But come on, we're all happy crunchers aren't we? So let's enjoy the vault en discuss the categories on a friendly manner. :)

And russkris, keep up doing the good work. :cheers:

[opyrt]

Yeah OK..

I have asked nano to change to from Math to Misc

I probably should just let this one go, but I can't. There is a discussion on the internet, and I have to win it! :D
(For those who didn't get it, yeah, that was a joke).

I feel that the Misc category should only be used for projects that do not fit anywhere else. Mathematic puzzles are just as related to math as SETI is with physics. Maybe even more so. Right now, Sudoku is cathegorized as a math project and NQueens is misc. That surely makes no sense. ;)

Anyways, this is just my opinion. I am one of many using the vault as a source of extra motivation when it comes to distributed computing. I'm not going to lose my sleep over this issue. In the end, it is the overall score that counts.

This is probably the last post from me regarding categorizing of projects.

Anyways, I would like to thank the DC-Vault Crew for keeping the Vault as alive as you've done lately. Dead projects are kept to a minimum and we all have a chance to improve our scores in projects. :cool:

[russkris]

:lol: You cant win this one mate... Only cause I can lock the thread....:lol:

You peeps crack me up...

Nano has moved it and we are talking about tweaking the admin tools so I can do it myself. No idea how long could or will take

Since you like to have the last word opyrt.. can you create a thread with the projects you think should be moved and why please, and we can have a thread for it....

[opyrt]

You peeps crack me up...

We aim to please! ;)


Since you like to have the last word opyrt.. can you create a thread with the projects you think should be moved and why please, and we can have a thread for it....

Done! :)

[russkris]

No now it's done....:lol:
