Welcome to the Prime Time Challenge (Reloaded)
Same song, second verse...let's hope with a different outcome. :)
PrimeGrid’s Challenge series continues with the "Prime Time Challenge (Reloaded)". The server survived its initiation but the Challenge did not. Unfortunately, there were other database related issues.
A 48 hour Challenge is being offered on PrimeGrid’s Proth Prime Search LLR application.
To participate in the Challenge, please select only the Proth Prime Search (LLR) project in your PrimeGrid preferences section. The challenge will begin 28 November 2008 18:00 UTC and end 30 November 2008 18:00 UTC. Application builds are available for Linux 32 bit and Windows 32 bit. These applications will be sent to 64 bit clients. As with all LLR application projects, there is no advantage of 64 bit over 32 bit.
NOTE: For the past several months, our primary focus has been on getting the PPS Sieve deep enough to start LLRing. While we have made great strides in this effort, we still need more help. Leading up to this Challenge, anyone with a 64 bit multiple core system is encouraged to join the Proth Prime Search sieving effort. Please see this post if you are interested as it requires us to enable the project in your PrimeGrid preferences.
ATTENTION: The primality program LLR is CPU intensive; so, it is vital to have a stable system with good cooling. It does not tolerate "even the slightest of errors." Please see this post for more details on how you can "stress test" your computer. WU’s will take ~2 minutes on fast/newer computers and 4+ minutes on slower/older computers. If your computer is highly overclocked, please consider "stress testing" it. Sieving is an excellent alternative for computers that are not able to LLR. :)
Please, please, please make sure your machines are up to the task.

Scoring Information
Scores will be kept for individuals and teams. Only work units issued AFTER 28 November 2008 18:00 UTC and received BEFORE 30 November 2008 18:00 UTC will be considered for credit. We will use the "prime score" method which is based on the n value (k*b^n-1) to score the challenge. The only difference is that the primary and double checker of a WU will receive the same score.
Therefore, each completed WU will earn a unique score based on its n value. The higher the n, the higher the score. This is different than BOINC cobblestones! A quorum of 2 is NOT needed to award Challenge score - i.e. no wingman. Therefore, each returned result will earn a Challenge score. Please note that if the result is eventually declared invalid, the score will be removed.
For details on how the score is calculated, please see this thread.
About the Proth Prime Search
The Proth Prime Search is done in collaboration with the Proth Search project. This search looks for primes in the form of k*2^n+1. With the condition 2^n > k, these are often called Proth primes. This project also has the added bonus of possibly finding factors of "classical" Fermat numbers or Generalized Fermat numbers. As this requires PrimeFormGW (PFGW) (a primality-testing program), once PrimeGrid finds a prime, it is then manually tested outside of BOINC for divisibility.
Our initial goal is be to double check all previous work up to n=500K for odd k<1200 and to fill in any gaps that were missed. PG LLRNet searched up to n=200,000 and found several missed primes in previously searched ranges. Although primes this small do not make it into the Top 5000 Primes database, the work is still important as it may lead to new factors for "classical" Fermat numbers or Generalized Fermat numbers. While there are many GFN factors, currently there are only about 270 "classical" Fermat number factors known.
Once the initial goal is reached, we'll turn our focus to smaller k values and higher n values. For example, k<32 complete to n=2M, k<64 complete to n=1M and so on. Primes found in these ranges will definitely make it into the Top 5000 Primes database.
For more information about "Proth" primes, please visit these links:
About Proth Search
The Proth Search project was established in 1998 by Ray Ballinger and Wilfrid Keller to coordinate a distributed effort to find Proth primes (primes of the form k*2^n+1) for k < 300. Ray was interested in finding primes while Wilfrid was interested in finding divisors of Fermat number. Since that time it has expanded to include k < 1200. Mark Rodenkirch (aka rogue) has been helping Ray keep the website up to date for the past few years.
Early in 2008, PrimeGrid and Proth Search teamed up to provide a software managed distributed effort to the search. Although it might appear that PrimeGrid is duplicating some of the Proth Search effort by re-doing some ranges, few ranges on Proth Search were ever double-checked. This has resulted in PrimeGrid finding primes that were missed by previous searchers. By the end of 2008, all new primes found by PrimeGrid will be eligible for inclusion in Chris Caldwell's Prime Pages Top 5000. Sometime in 2009, it is expected that over 90% of the tests handed out by PrimeGrids will be numbers that have never been tested.
PrimeGrid intends to continue the search for indefinitely for Proth primes.
What is LLR?
The Lucas-Lehmer-Riesel (LLR) test is a primality test for numbers of the form N = k*2^n − 1, with 2^n > k. Also, LLR is a program developed by Jean Penné that can run the LLR-tests. It includes the Proth test to perform +1 tests and PRP to test non base 2 numbers. See also:
(Edouard Lucas: 1842-1891, Derrick H. Lehmer: 1905-1991, Hans Riesel: born 1929).

We would like to pre-stress the server on 27 Nov 2008 at 17:00 UTC. We will be monitoring to see if the previous Challenge related issues present themselves again.
If you are interested in helping out, please select Proth Prime Search (LLR) in your PrimeGrid preferences and hit the server at the prescribed time. We are hoping for a good mixture of small and large cache hits (EDIT: a few minutes to a few hours).
Thank you for your help!

Yes, the pre-stress is the day before (25 hours in advance). The largest cache we recommend at that time is just a few hours.
The idea is to hit the server hard with many requests so we can simulate the start of the Challenge. We'll monitor conditions and make adjustments. This way when the real Challenge starts, we hope to be better prepared.

I'm in doubt. I think that i'm not in until you describe whats happened at first time this challenge starts. I'm curious admin, so you don't scare me with words like raid, mysql, etc. And I think there's a lot of tech guys who also curious as well. so please tell us WHAT'S HAPPENED AT FIRST TIME.

If we knew exactly, we'd not need a pre-stress test :)
Basically, the servers were not fully loaded (unix load level below 2 on WWW server - 2 cores available; Windows load level below 20% on DB server - 8 cores availabe), but access to the website (and work issuing) stopped. This might be because:
a) Network issues between DB and WWW servers;
b) MySQL stalling while handling some specific query;
c) Apache webserver stopping responding;
d) BOINC bug, stalling work send.
Sadly, I wasn't around when it happened, so with the pre-stress test I hope to pinpoint the exact cause out of these. If I had to bet, it's either b) or c). a) is unlikely (nothing in the logs about lost connections). I don't know for sure, and cannot attempt a fix until I know.

Thanks for info, Rytis.
Can you give us numbers on load like db querries per sec, connections per sec on network?
As for pre-challenge stress-test, I may have couple dozens of cores...

Will do the best that I can. However, the 27th is a major US holiday (elusive something involving a gobbler and pumpkins), and many of us have the 28th off as well. Just a musical phrase to consider (from a musician).

The load balancer/firewall of the data center the server is installed in is out of consideration?
As I understood the server was hammered with requests - at work our web application security software (WASS) would have banned those clients temporarily on a per-IP-basis.
This would amount to following scenario:
- clients are asking for work
- clients get work
- work obtained by client doesn't satisfy cache-settings of project
- clients asking for work
- clients getting response that work-quota is reached
- clients go to sleep for 60 secondes
- clients are asking over and over for work and getting response that work quota is reached
- WASS is blocking those clients due to DDOS-pattern
- no more work issued for these clients
- website also not accessible for these clients
just my 2 cents...
If the data center does not have WASS - which I can't quite imagine - that scenario is out of question.
kind regards
p.s.: I will try to do my best @ 27.th and the following two days...

@ roadrunner_gs - AFIAK, clients go to sleep for longer and longer periods when no work available.
Blocking website on per-IP address is not a wise idea. Users would not be able to look at forum to see what's going on, report problems etc. Futher more, clients would not be able to upload and report work already done. If they would be behind NAT, a whole farm might get blocked because of a single client going nuts...
The issue of network load is a good point nevertheless.

I'm sure you read all logs, and if u say u don't know why this happend, this is a UNKNOWN issue. Bad. Hope you catch it at 27. If something should happen let it be at 27 not 28.
Does BOINC server version is up to date?

Did it take 26 minutes to get first work or to fill cache?

To completely fill the caches. Each machine is a quad and is set for .25 of a day cache.
I thought that it was a very good start. |

I switched my desktop today to PPS-LLR. But there is something tricky for me. Normally it takes around 2:11 minutes to finish one WU. And from time to time there are some WUs that take 2:50 or longer. Is this normal?
Edit says: Just looked on the laptop. Same thing there. Most WUs around 380 seconds, some over 500 seconds.

We have hit a bigger FFT size so we will see a time increase at ~30%

The pre-stress on the server to the Prime Time Challenge (Reloaded) has shown a substantial improvement. A few more adjustments should make things even better. Therefore, the Challenge is on for 28 Nov – 30 Nov.
Changes to Apache settings helped alleviate the problems. Additionally, we will be making adjustments to the available WU buffer (what you see on the front page), max WU cache (how much a single core can download at one request), and project WU share (how many WU's BOINC has available for the PPS LLR project).
These changes will only affect the start. Once everyone has work, all settings will return to normal.
Thank you to everyone who participated in the pre-stress. If you wish to stay on till the start of the Challenge, please remember to lower your cache before 18:00 UTC tomorrow so you can optimize your Challenge score. :)
Best of Luck in the Challenge and in finding primes!

The computational time is increasing on a regular basis. Two days ago my Laptop (the absolutely slowest Core Duo you can find) finished PPS-LLRs in 600 seconds. Then 800 seconds. Now the workunits take either 1000 or 1300 seconds. The computation time is increasing quite fast, considering the doubling within 2 days. During the challenge with more people crunching explicitly for this subproject, do I have to expect another factor of 4 or 5 over the weekend?
Lets see how many workunits I can crunch with my Quad Core. But I am pretty sure that it is impossible to reach any reasonable challenge score (with reasonable I mean not zero) with my two processors/6 cores, although running them 24/7. |

You have to expect 1300 in yor case. We have reached a higher FFT and that increase time.

I'm getting through to the server but getting no work available.
5 minutes and only got 1 work unit. Not looking good. |

Same here, no work available but then I managed to get a few units so one of my machines has work for the next 5 minutes or so ... Hope this starts working better soon! |

Poor Apache. It's maxed out and even over at times. 258 connections while 256 are allowed, meaning there's no coms going out to anyone. ;-)
Poor Willy as well, I hope he doesn't need to sit besides the server all weekend long, adjusting it.

It's not been 100% flawless, but I'm pretty happy with the way this challenge started compared to many previous ones. All my hosts got work without having to wait for too long, are gradually filling their caches, and the website has been available almost all the time. Well done chaps!

Work is available and going out as fast as BOINC will let it. Please keep us posted if you still don't have work. Also, see the Meebo chat at the bottom of the main forum page.

Looks like I may have spoke too soon, as more of my hosts attach VIA BAM, looks like work is getting to them. Should have most hosts attached within the next 3-6 hours.
Thanks!!

Thanks for all the feedback. We will continue to make adjustments and increase max WU cache...currently at 119 WU's.
BTW, we just passed n=400K. The Challenge started at n~393K. Great work everyone!!!

150-250 is just about right - too high of cache can kill BOINC graphical interface performance..
These small WU's however are causing havoc on my internet bandwidth...

This happens, if the server load is that high, so that your client's connection times out. The server still gets your results and mark them as reported, but it can't tell your client to delete them from your list. Your client will retry to report the tasks, but the server already marked them as reported in the database and returns that message.
So everything is ok, no work lost.

One of my quads has ~130 of these since challenge started. It is the one that failed to report larger portion of completed results. When it succeded, many results were already checked and WUs closed - hence the message I think.
Another host has only ~10 of them.

I'm getting them too. They usually follow this:
Scheduler request failed: HTTP internal server error
It also appears as though some of the results are getting lost:
11/29/2008 3:05:59 AM|PrimeGrid|Message from server: Resent lost result pps_llr_24888072_1
I hope none of my results get 'lost'...

Thanks for the information.
Most of these messages were occuring on a host I am having a few issues with. (caused by a Woodall WU that got past me prior to the start)-- So I thought I may be causing the problem.---- As I don't like to abort WU's at any time-- and I absolutely refuse to abort at 90%-- I have cache problems with this WU suspended--- If I leave it suspended I don't get any more WU's-- I have to resume this WU briefly to get additional WU's then suspend again.
Other curious thing is this host (Duo core) will not report automatically-- even after 4hrs or so. I have tried adjusting the cache to a variety of settings all to no avail-- Looks like I will be setting the alarm clock (UTC+10 here in Oz) to keep in the challenge. |

I see the PPS WU's are stretching out.
Duo Core --4' 40" ( 2' 30" 2 weeks ago)
AMD (1 CPU) --7' 50"
P4-- 10' 30" (poor ole' P4-- should retire it)
(11am UTC)
How are other hosts comparing--
Numbers are getting bigger!!! |

Please do not take this as a negative criticism but I feel I should point out my disappointment. We were asked before the challange to test out the new server with PPS LLR. I did as asked. The problem is that my ISP set-up is that I need to have a cache of two days. I was not warned or in deed did not recognise the fact that I should have aborted all units at the start of the challange. As it stands now, I am not in the challange as half way through I still be working on units that are not recognised for the challange. Not only that, I am now receiving messages that the uploaded completed units are rejected as they are already completed. Disappointing...

Pete, it was stated very clearly that "Only work units issued AFTER 28 November 2008 18:00 UTC and received BEFORE 30 November 2008 18:00 UTC will be considered for credit." - see John's first post in this thread.
You don't need to abort units that don't fit to the challenge. Just suspend them (if not in danger of miss deadline) and resume after challenge is done (or when you go out of work).
I agree it may be discouraging if you do not have permanent internet connection to enter such a challenge as this. But it's a challenge, isn't it?
P.S. I have 26 more hosts not attached to PG and still in hesisation to enter challenge with them because I also have some concerns....

I can understand your disappointment but how else would the challenge work without cheaters ? People would just download a bunch of units and then pull the plug and upload all at once when the challenge started - that would skew for the rest of us...
Not only that, I am now receiving messages that the uploaded completed units are rejected as they are already completed. Disappointing..
Well, if you'd read Post 11755 you'd see the explanation clearly:
This happens, if the server load is that high, so that your client's connection times out. The server still gets your results and mark them as reported, but it can't tell your client to delete them from your list. Your client will retry to report the tasks, but the server already marked them as reported in the database and returns that message.
So everything is ok, no work lost.
So reading up on what others write could be "nice" especially since you're "disappointed" yourself... |

Honza-- Good comments-- Comiserations to Cruncher Pete--- HOWEVER be careful about suspending old WU's-- Your cache will still recognise this-- I know because I have one in one host-- to keep this host in the challenge (my best PC) I have to manually get work every 4 hrs or so---
I would like to congradulate PG-- despite my problems things have gone great so far-- |

Pete-- From a fellow Aussie-- Sh*?t happens mate-- The first challenge (aborted) also had me buggered-- I ended up suspending tasks and emptying my cache to try to get into the race (I usually crunch the longer WU's)-- My RAC still hasn't recovered from the first fiasco--- But I'm here again for the next round-- Read the threads mate -- all the info is there-- Careful about suspending tasks though-- see my thread

You don't need to abort units that don't fit to the challenge. Just suspend them (if not in danger of miss deadline) and resume after challenge is done (or when you go out of work).
In my point of view you will not get any new work as long as you have PrimeGrid tasks suspended.

Blast, uploading with stuff worked on before the contest at the very moment it starts isn't counted.
WU's have to be downloaded during the contest to count.
===
I have a different problem. Though my cache is set to 0.1 days, I discovered this morning that stuff finished at 'round 8gmt still wasn't sent by 8cst (Midwest USA). It had been sitting there for six hours not sending anything (and, consequently, not receiving anything to crunch).
Any solution to this?

Seems like the recession is affecting prime work too...
The server is sending me "pink slips" saying, "Message from server: No work is available for PPS LLR".
The main page also says, "Available: Proth Prime Search (LLR) 0".
I didn't have a very big cache; I'm going to have to start doing sieve if I don't get more work very soon.

I have about at minimum 10 hours of work on my three fat clients (C2D T8300, C2D E6550, Xeon 5405, Pentium M 2000), i am not frightened at the moment... ;) |

I had this problem at start-up. So my cruncher did nothing for the first 6 hours of the challenge.
Same happened again last night. So another 7 hours of doing nothing.
And in about 30 minutes I will be out of work.
So give me something to crunch! Otherwise you can find my at abc.

For those whose clients are not sending work, are your preferences set to allow network use all the time?
Meanwhile, my fast machine's out of work, trying to get a sieve when it can (those are being reported as unavailable sometimes too), and my slow machine will run out in a little over 45 minutes. (3 WU - it's really slow!) |

|

Just in time I received 26 WUs. Will take me about 20 minutes. I hope more WUs will come. |

i have had no problems from the start of this challenge getting wu's..

The servers are teasing me.
Just before I ran out of work (with 20 minutes to go), I got new WU's.
Now I was down to 15 minutes of work to go, and I received new WUs.
I will be crunching for 2 more hours at least.

Yay! They got it back up and running again!
Thanks guys!

Yep, certainly an issue with these short WU's -
I am getting resends and already reported errors all over the place..
I am glad this challenge will be done tomorrow - Don't know if my poor network can take much more of this beating.
And I remembered now why I don't crunch this project more, I have had to down-clock my boxes. This project is very hard on CPU's - Temps shooting skyward, hosts locked up and or rebooting - once the challenge is done, I will have to go back to projects that don't beat the CPU like a red-headed stepchild.

Due to long offline times, I just reported 450 WUs. Two times, the result was an 'internal server error' (I suppose script or database timeouts). The third attempt was successfull, followed by a bunch of 'result already reported as success' (which would support the script timeout theory) and a list of 'recent lost result'. What is causing the latter errors?
While downloading WUs, some of them (20 consecutively out of 200) produced the following error pairs (downloading two at a time, times are GMT+1):

I have had over 500 kicked because they were already reported as successes or resent because lost. have you also noticed the teams are updating scores but participants are not. Granted just getting the bugs out but it's always cool to see how your doing. I did read somewhere that some of the wu 's would be duplicates but they said it would be minimal. |

Yes, we are aware of the user scores not updating. That will have to wait a few hours longer to be resolved.
The already reported WU messages you're getting are OK...sort of. :) Your client attempts to upload WU's and the server times out before responding to the client that they have been received. The next time your client uploads and the server is able to respond this time, it gives you the correct message that they have already been reported...by you.
The timeouts are happening simply because there are too many connections to the server. While they are a nuisance, they are expected with all the activity that's hitting PrimeGrid's server right now.
Hopefully everyone has at least 20-30 minutes cache and therefore, can handle a time out or two...or any of the other load related messages.

Your client will retry to report the tasks, but the server already marked them as reported in the database and returns that message.
So everything is ok, no work lost.
I've asked this question and got this answer from pschoefer
I've had a few resent WU's-- they were not sent to me previously-- just crunch them and keep going. |

The timeouts are happening simply because there are too many connections to the server. While they are a nuisance, they are expected with all the activity that's hitting PrimeGrid's server right now.
Hopefully everyone has at least 20-30 minutes cache and therefore, can handle a time out or two...or any of the other load related messages.
Not exactly...a low cache setting can result in a machine not reporting until it is "too late" to refill the cache, which can result in a longer dry spell. I have machines that ran dry earlier today because of this and were out of work for between 1 to 2 hours (was away and couldn't check on them).
If this was expected behavior, then a notice to up one's cache (at least to more than the .25 days default) would have been nice. Live and learn I guess...

The downtime earlier today was unexpected and was a result of WU generation not working. It lasted ~4 hours. True, a 20-30 minute cache would not have survived this outage.

I know...and I am not complaining. Just mad at myself a bit for not thinking about it ahead of time (too much of real life stuff going on for the holiday).
The 3 hour outage caused a side effect that has been problematic for me. With the shorter cache settings (a good default for those of us on multi-projects normally), the machines ran dry, and then with the increasing BOINC server backoff times, are now sitting running the other projects until another timed update (despite the drastic increase in resource share that I normally implement that essentially devotes the machines to PrimeGrid during the challenges).
Perhaps for future challenges, it might be a good idea to recommend a cache setting of at least 50% of the challenge duration?
Edit: The machines affected are remote, unfortunately.

Well.. there was a post somwhere I read telling us to increase the cache once the challenge was successfully under way---
It would be very helpful if the PG guys put out a list of do's & don'ts & recommendations prior to a challenge for us poor fools who don't know a lot about how PG & BOINC works--
I suspended a big WU (90%) just before the start-- I had no idea this would prevent this host from requesting work & apparently reporting.
This is stuff I need to know-- Luckily I watched the start and figured out the issue after about 15min--
Following the posts I see a lot of others were caught by this issue--
Even a page of script somwhere explaining the various functions etc of the GUI would help-- All you need to know seems to be in the message posts but it gets pretty tedious searching all these.

If you have a look at your message logs you won't find the original WU's-- They are lost from others-- you are now being asked to crunch them--

Sorry, the Participant stats script runs for over 5 minutes and locks everything up. With the level of activity we are experiencing right now, we are not able to afford this.
As pschoefer pointed out, BOINCstats does have two manual updates. Expect no more updates until after the Challenge has completed...at which time another manual update will be performed.
We apologize for this. We know it takes a lot of the fun out of the Challenge. :( Please note that team stats are not as heavy on the server and will continue to run as normal.

[B@H] Clooney - BOINC knows more than one project. You should have set another project(s) with a low share as a backup. Or should have used better BOINC cores like Boinc studio, which has ability to set backup projects (if no work for main project, start backup projects and get as little work just to avoid cores being idle).

Since the challenge is coming to an end here in just over an hour.
I am trying to upload and report the last of my crunched work.
On some hosts I have 100+ but am now getting the project down, or http errors...
Stats are not updating - nobody knows where they are in the standings.
Kind of like racing in the dark with no idea where you are in the race - yawn!
What gives - IMO this has not been the best showing for a challenge- Yes, the servers got stressed, and we found out that it can not maintain this load.

Hi zeitgeistmovie,
I've tried to give you a little challenge :) but it only was a challenge of my patience and my nerves.
So many errors on my boxes...
http errors or cannot attach to server etc.
To much dry run in this competition. Only the last 5 hours there was enough work for my bigger boxes.
But the worst thing is the missing of stats.
This was only little fun for me.

Agreed, not a great race... I did notice you started off with a BANG!!!- I got started late, was not even sure I was going to join in until I did. I did no pre-planning (my fault) so I still had a cache of MW and 3x1 burning. All in all -
We STILL don't know who won :)
With as many boxes of mine that ran dry - or over-heated (I have most mine overclocked to match a project, and PG has a real hard time with overclocked boxes) Ahh well.
Good luck!!
Setting PG to NNW -... back to my regular crunching! |

Too many complaints, everyone knew from the outset that this challenge was to push the server to the limit. Looks like a success. I saw no fewer than 6 individual items that need work. What does that show us? They have been identified and now the process of improvement starts. Thanks for letting me participate, look forward to the next one. Patrick |

P.S. 7 items, the timer is past 48 hours. Turn it off |

only thing I wished for was stats, but that could wait. It was a fun challenge for me though :)
It was a great stability test for both the server and for people's systems. I found out I have work to do on one system!

yes there were probs with the stats
yes there were probs with getting workuntis
yes there were probs with the heat on (overclocked) computers
but
we all are gone through 48 hours of challenge
we all spent our personal-time and CPU-time for the project
we all knew before, the short workunits will stress the infrastructure more than any other challenge
so
I would like to thank Rytis, John and all the others, which gave the personal best to lead us through this "abnormal" challenge
PS: hope we get stats soon ;)

That was a hell of a ride.
All manually ordered updates went through just in time before the deadline.

I got this error at least a few times. I have no idea how often 'cause the wife actually ran the computers for me as I was out of town. Anyway, when I got home I saw it and was wondering two things: first, did anyone else get this error, and second, besides the obvious problem, any idea what the problem was with the database? If it was my end causing it, I would like to know so I can fix it ASAP.

I agree with others in that this was a good challenge for the server. It was really stressed and has proven itself. After this, it should be able to handle most anything for years to come.
As for the users end of things. Those who had the larger work buffers set could obviously survive the outage and the no work available times while those with the smaller buffers just couldn't. Even if guidelines/rules are posted as to exactly how/when/what to set/change the work buffer numbers to, until PG can actually do the controlling, there will be people that won't stick to the plan.

it's not on your end, it's mysql configured too tight. not timing out because it can't handle the stress, but hitting the limit configured server-side.
this all could have been sorted out during the challenge..

3 things have been proven: servers are fine, current config is not able to handle a challenge like this and support@project did not not take the chance to get things sorted.

I don't think many people would be happy about a project 'taking control' of their cache setting, and I wouldn't take part in a challenge where I was told how much work I could cache. Don't get me wrong, I don't run a 'farm', I'm only a single core cruncher.
One fair way of limiting downloads would be the Milkyway route. 20 (or whatever) wu's per core per download. I'm not sure how much stress this would put on the server, quite a lot I would imagine!

At the moment I am crunching my last Prime-WU's.
I will be here again with the next challenge. I learned a lot about how to keep my cores crunching. Just waiting for the end-results. I want to know if I made it in the top 100 :-)
By the way, no heat problem here. I just open my door to let in some cold air.

I never said anything about them taking control of any cache setting. I am guessing you mean work buffer. And I did imply that but didn't actually say it, and never meant exactly that either. Sorry for the confusion.
They can however "control" the amount of work we can get just as you describe. The work buffer could be set at 10 days on the client side (I think that is the max), but if you are only allowed x number of wu's per core at a time, that is the control. Call it a limit or any other term if you wish, still the same thing. You cannot get more work from the project, so who is in control? |

Sorry I misinterpreted your post. But we both agree that the challenge can be 'controlled' fairly by the project, using the wu'/core/download method? The only thing is that a quad would get 80 wu's compared to a single core's 20 wu's (using MW as an example) but that is unavoidable.

No biggie. I failed to make myself clear. And yes, we agree.
I think the difference between us is you are talking wu's and I am thinking time. PG knows how much time each wu takes per core on each active machine. Not just by CPU type, but on each machine. It could average that over the last 90 days or whatever for a particular wu type for a particular challenge. Then they would know how many wu's to send each machine to give it a certain amount of time to work before it would need more wu's. This could be gradually increased as the load on the server asking for initial wu's slows. Then let it get to a max of 12 hours worth for every machine until about 13 hours before the end of the challenge at which time PG would start backing down the number of wu's allowed each machine.
This way there can be no requests for entire length fo the challege at 5 minutes after the start time to clog the server and no machines with hours of work left to do at the end of the challenge.
This method could be used for any type wu and for any length challenge on any project.
If anyone is thinking it, don't even ask. I can't program it. I might be able to make it a bit clearer, but that would be it. |

[Quote] Ok— I’m an engineer – not a guru—but any solution has to be simple—easy to implement and controllable – and logistically feasible for the project scientists—
Lets turn the problem completely upside down--- Have intending participants register their computers--- give out WU’s according to 1, 2, 4 or 8 CPU.s (or whatever)--- Run the challenge on a number of different levels— Shortest time to complete Issued blocks of WU,s, Handicap honours where an old PC might get a win--- and of course most overall work done—
In other words –change the challenge from the number of WU’s crunched in a certain period-- to the time to complete a block of WU,s--- A challenge run in this manner could be run at any time with little disruption to the server – and consider the statistical data PG would get—accurate data on how long the particular WU takes on a variety of PC’s---
This changes the challenge from –WORK done in TIME to—TIME to do WORK—No doubt there would be issues to resolve ---- comments gentlemen???? [Quote]
I Made the above & similar comment at the end of the aborted challenge.

I'm a little bit insecure about the running clock, I've not much time to read in this challenge because of renovating the flat. After all the problems to get work and the time was needed to control the PCs I've feared, the challenge runs over the time. There are not much information on the start page about the status.

I don't know why, but I have over 2000 completed WUs sitting on my machines and they won't upload. This has occurred for the last 5 hours. All of these WUs should have been uploaded in time for the finish. Now they will not be counted.
Not a happy camper. |

Lets turn the problem completely upside down--- Have intending participants register their computers--- give out WU’s according to 1, 2, 4 or 8 CPU.s (or whatever)--- Run the challenge on a number of different levels— Shortest time to complete Issued blocks of WU,s, Handicap honours where an old PC might get a win--- and of course most overall work done—
In other words –change the challenge from the number of WU’s crunched in a certain period-- to the time to complete a block of WU,s--- A challenge run in this manner could be run at any time with little disruption to the server – and consider the statistical data PG would get—accurate data on how long the particular WU takes on a variety of PC’s---
This changes the challenge from –WORK done in TIME to—TIME to do WORK—No doubt there would be issues to resolve ---- comments gentlemen???? [Quote]
I Made the above & similar comment at the end of the aborted challenge.
I remembered reading that somewhere as I re-read it right now, just couldn't place it. But I would think on each PG project you have worked on for a fair amount of time, they already have that data for your machine. Not positive, but I can't see why not.
I thought the challenges were about throwing everything you had at a project to see how much progress the project could make in a limited amount of time.
And the individual stats really mean nothing to me as some people run their own farms and some have the power of a university full of computers behind them. Not fair to even compare someone with say my 6 cores to someone with 1 core much less to a university or a business. So I understand what you are saying about the stats. But those computers are never used or mostly never used during challenge times. I use my computer any time day or night. That doesn't sound fair either. So the % of time Boinc is active and the % of time the computer is on and being used for other stuff and I don't know what all would have to be taken into account.
I think a challenge should last at least a week. Get a good, rounded variety of use out of the computers during their normal activities. Run it just Monday-Friday.
The challenge is just more fun if we are all "racing" against each other at the same time. IMO
Nascar wouldn't be any fun at all with only one car on the track at a time. |

Finally got all my WUs uploaded. I had to babysit a couple machines hitting Update every couple of minutes. |

I agree all cars shoul be on the track at the same time-- but at the moment we have "Ride on lawnmowers" racing against "Formula 1" -- my suggestion was more about 'like' competing against "like" to encourage more participants--- the comment about about WU's against time was offered as a solution if the server could not cope with the load to run a small WU challange-- It now looks like it can-- |

I do not know, but from my point of view WRC (World Rally Championship) is fun to look too.
And there everyone competes against the clock and the others but seldomly meets the others because everyone starts on his own (like in slalom skiing)
But that is a question of like or dislike.
How about every user gets a defined bunch of WUs and crunches them and afterwards the users/teams are sorted by crunched time? This would spare the server some load but take some (or a lot of) time to get results, maybee a deadline should be defined too...

All in all it was a nice and excitingly contest.
Our team already looks forward to the next competition.
We observed this 48h whole time and found no dry-outs for us.
All we could cry about: we reached place 31 in teamstanding, so gratulations to Babylon 5, it was a great fight. Next time we will hit you to the ground with opterons and i7 ;-)))

@HighTech67: I agree that comparing 'private' people using one ore two PCs with administrators having a whole university/company is inadequate. So lets compare your score with mine (6 cores, C2Q9450 2.5GHz, C1D-T2300 1.6GHz, no overclocking) ;) Rank 120 so far.
Counting the time to complete a certain number of WUs is tecnically difficult.
First, again a single computer would take ages, whereas a server farm finishes in hours/minutes.
Second, you can only estimate the time by comparing 'task created' and 'result send'. But BOINC is only uploading results when requesting new ones (which may take some time) or on 'high-priority' tasks close it schedule deadline.
In my opinion, the challenges are good as they are now. It helps the project to concentrate on a single subproject and finish lots of work in short times. The PPS-LLR was just extra ordinary due to the short runtime per WU leading to a huge amount of tasks. |

Sorry if this has been addressed elsewhere, I've looked around a bit, but not seen anything. The last 36 hours or so my pending WU's results in a blank page. I've tried waiting a bit to see if it would come back, but so far nothing.
It started with about 12 hours left in the challenge, at that time there were about 10,000 pending WU's. Just curious if anyone else has this problem, and if anyone knows why it occurs.
Thanks in advance.

I agree that this is somewhat unfair, but you also have to keep in mind that a lot of "private people" put a lot into their Boinc farms, and can be competitive with those that install at work or school.

PHP hits memory limits because of the vast amount of pending tasks. As the validator deals with some, you should start seeing them again.

*lol* sure - but your P4 should stand on a rock in antarctica or use a Vapochill(tm). We work with "normal" Company-Computers. (Dont ask me, why they have to be Quads or Duals, I dont know. But BOINC is the only project to make them usefull at all.)

I've address problem of pending not showing before, not a big deal really.
But Workunits waiting for validation doesn't seems to be smaller comparing to yesterday.
Do we have some in and out numbers from validator?

Thanks, didn't think they would be lost, but it does make one wonder when you hit a blank page :)
Perhaps it would be possible, at some future time to add a line to the code that if a number of results are returned that exceed the data limit, it instead displays a message that there are too many results to list. I'm sure for now though you already have your hands full :)

Adjustments have been made to free up more resources for the validator. It's starting to come down now.
Also, Challenge Participant stats have been manually updated Mon Dec 1 15:22:58 2008.

""2/12/2008 7:21:24 AM||Internet access OK - project servers may be temporarily down."""
I found this to be a very strange message as I had no internet access for some 6hrs when the message (and many like it) appeared-- Our whole region was down due to storm damage--
Seems the GUI is very quick to blame the PG server--- and very unjustly in this case.

Well, I can see my pendings again, so that's a plus. Having dabbled in PHP a bit in the past, it seems that it would be a fairly simple fix to either:
A) Break the output into separate ranges passing the last database entry # to the page links it creates at the bottom. (or assume number by page number, for example 1000 entries per page, page 1 = 1 - 1000, page 2 = 1001-2000, etc.. just do a count to figure the number of pages.)
or at the least you should be able to:
B) truncate the message as it's being constructed to prevent this from happening, perhaps with a small bold note at the bottom stating the actual number of pendings and something such as "Additional pending WU's omitted from list."

Yes, the result of the query is stored in memory and then the page(the result-table) gets created. 'Streaming' the results whould be a much better solution.
I did not look too far in the code, but maybe there are even more columns returned than necessary.
Is that what you mean?

Yes, the problem is in the streaming. It should be printing stuff out as it comes from the database, storing only one row at a time in memory.

Sounds good.
Having a total number of pending and "pending WU's omitted from list " (even without any WUs) would be better than having a blank page I still see.
EDIT: I understand that this is exceptional situation and it would not happen during normal conditions...

Now I need the famous e-mail (the minimum for the top 5000 seems to be just over 104k digits).
Edit - looks like someone called Harvey already found my prime in Nov 2007.

I think it's safe to say that the Prime Time Challenge was far from perfect. Again the participation greatly exceeded our expectations. The one positive outcome is that an incredible amount of work was completed. Basically, 20 normal days of work for PPS LLR was crunched in 48 hours...and that was with all the problems. Unfortunately, much more could have been accomplished minus all the connection issues.
It is never our intention to run a Challenge with problems. We made several adjustments that only marginally solved some of the problems. We learned a lot...mostly about the limitations of the BOINC and server software. Until better solutions are established, we'll be avoiding Challenges on applications where the WU is less than 4-5 minutes.
Over 3.3M WU's were completed in the Challenge. The validator took almost 60 hours after the end of the Challenge to clear the backlog. Currently we are seeing a lot of expired WU's that were abandoned at the end of the Challenge. If you see the PPS LLR buffer on the front page above 2000, then you'll know that a lot of WU's are expiring. If you see the buffer at or below 2000, then you know the current effort is staying ahead of all the resends.
A manual update of Challenge scores was run today. We have seen an excellent "clean up" mostly due to the short WU's. Therefore, we expect to finalize the Challenge scores after 18:00 UTC 4 Dec 2008...although we don't expect much to change by then. It will then take about 24 hours to purge the LLR table in the database and then we'll be able to enable range stats again.
The Challenge started at n~393K and finish n~432. Currently n is at 440K. More info about primes found will be available after everything is finalized tomorrow.
Thank you to everyone for participating.

Fish found the prime. It was a missed one in the original search:
171*2^404379+1
The Prime Pages entry can be seen here.
We have not tested all primes yet for GFN divisibilities so there may be some new divisibilities there.

The challenge is now well over and done with. I am just wondering when will you guys have time to tell those who participated thank you and fix problems that still persists. i.e Internall HTTP errors. The last message you have in the News Archive is four hours into the challenge. Front page messages are effective as a lot of users have no time to search through the Forum for news... |
