@Marc,
Recently you announced that DPC has taken LC to one of her projects. In the DPC forum they said that to overtake Seti@Netherlands was a piece-of-cake before 01-01-2007. Ofcourse we've taken that gauntlet!
You can read here all about it (Dutch)http://forum.seti.nl/showthread.php?t=14142

Now we've succeded in holding DPC behind us till 2007, most of the boxes get back to other projects.
Personly I had 33 boxes on Leiden Classical (I first had about 10) In the time those boxes did LC my overall RAC dropped from about 13000 to 7500 !!
Check it out here http://nl.boincstats.com/stats/boinc_user_graph.php?pr=bo&id=468844 Why are credits on LC that poor? Or is it the zero credit problem?
After all a RAC of 4300 isn't a lot for 33 pc's!!(most P4's)
And I don't wanna mess with the 5.5 manager. (who is still not banned!)I leave my AMD's on this project (they seem to do better then the pentiums) for old times sake.
To DPC....it was fun competing with you!

IMHO, the Boincstats pictures don't show a dramatical drop in your overall RAC, or did I miss something? Anyway, afaik Boincstat RAC is calculated independently from the project RAC. Nevertheless, they should be about comparable after a fourthnight of sustained crunching.
It's known LC tends to have 'a problem' with pending wu's. If you're 'unlucky' to have a hardware/OS/software combination which is rather rare on LC, your number of pending wu's can get quite high. After a couple of weeks though, this 'problem' should level out to a steady amount of pendings, I have between 700 and 800 wu's pending.
All-in-all, due to this typical LC behaviour, even if you're moving your 30 boxes to other projects, your RAC will stay high on LC for at least some weeks to come.

aad,

You should check out the your results and see if you're getting a lot of "Invalid" results (giving you 0 credit - dragging down your average). I have 3 pc's with very typical (PIII/Win2kpro, PentM/WinXPhome, AMDX2/WinXPpro, no overclocking or any of that stuff) configurations that cannot get a valid result for any of the "Classical" WUs - not one. The other WUs ("trajtou") Leiden sends out are handled fine by all of my machines. I decided to stop getting new WU's until the issue is addressed. After all, it's a waste of both my computers' time and Leiden's time if none of my PC's can do Leiden's work.

There must be a problem with the "Classical" application - it's just not being addressed by the moderator.

See these threads:

Dear Chris, it is beeing addressed, as was also explained in the threads you refer to... I'm repeating myself: it will take time... I'm currently busy debugging the Classical app with all sorts of inputs during my Holidays and so far I haven't found an issue yet... All data returned by hosts here seem fine too... So before concluding it is an application or a project issue, please be open minded and reckon the fact that there are numerous other host just doing fine as they are...

Furthermore, the 'pending' problem of ColdRain should not be an issue anymore and too aad, I do not yet fully understand how your RAC dropped.

The thing I'm thinking of is that due to the increase of hosts, your are now competing for work with more machines. The shmem tables have not been increased because they cannot. The other thing might be because I tweaked the server to not issue more than 16 WU's anymore and the WU's have also increased in CPU time too... Hard to say what's causing this... This issue is noted and as soon as I have more on the matter I'll tell you guys...

m.

Thanks for the update.

aad's issue sounded very similar to the issues I had been having - a lower RAC would be indicative of higher incidence of invalid results (about the same % as I was seeing on my systems). That's why I suggested he take a look at his results.

Is there anything I can do to help - like run something on one of my PC's here and give you a log file or debug file, raw output file, or something? I'm offering - it's up to you.

Thanks again, and good luck.

Chris

I'm happy to confirm this. ;-)
My number of pending wu's is dropping at a (slow but) steady rate, my average now is at about 575.

Marc, thanks for the reply.
About pending credits;(at the moment of writing this) Pending credit: 1,604.44
And dropping fast now. A few days ago it was about 2600 !!
Most of my boxes have finished their work with Leiden, exept for 4 AMD's.

At any time in the last weeks it was not a issue to gain work because I set my queue to 4 days so there was a constant flow of work.
Increasing CPU time imho was a good thing. The downside of that is that when you have a 'zero credit wu', you crunching longer for nothing.......

Just an idea; can you do a query in the database for those zero credit results?
Perhaps you can make something out of it. (and give 1 credit for each "voor de moeite")

The pending credits seems to go up and down. Mine have risen from 1400 to 2200 in 2 days time. I think one of the main reasons is that in some categories (like Pentium D) you always share work with the same people. If for some reason they don't connect for a number of days, your results stay pending.

My pending credit has shrunk to 1044.
My oldest wu is this one;http://boinc.gorlaeus.net/workunit.php?wuid=1541700
Why it is still pending?
