1) Message boards : Cafe CPDN : Bets on for 20,000 active BOINC hosts?? (Message 8167)

I'm seing some interesting spikes on the user and recent credit graphs:
<a href="http://www.boinc.dk/index.php?page=stats_project_astropulse&amp;project=cpdn">www.boinc.dk</a>

Going to speed up the number of computed models quite a bit I think.

The issue here is usually that it takes a few "switches" before it stabilizes.
4) Message boards : Number crunching : Good perf boost with optimized build, but... (Message 5417)
Posted 16 Oct 2004 by old_user73
Post:
You are probably talking about optimized core clients?

If that is the case it isn't going to give you any performance boost at all since the core client is only taking care of 0.0001% of the work - uploading and downloading etc.
The real work is going on in the application (hadsm - the worker, the simulation) and this one isn't opensource and hence cannot be optimized in the same way.

So in CPDN optimizing the CC doesn't change anything at all - except the dhry- and whetstone numbers.

&gt; Through www.7byte.com 's Hot CPU Tester, It has been determined that the CPU
&gt; in Socket 0 is inept when it comes to deriving Pi.

Great you found the error =)
Please first switch the CPUs to see if it is the motherboard socket that has an error - it has happened, although very seldomly...

&gt; But the tests doesn't realy help. I have done it and all worked
&gt; fine.Nevertheless CPDN crashedon my overclocked machine. So I had to go back
&gt; to standart.

Oh, the test works - they just don't test the stability of your computer as you would expect, they test the stability of the RAM. For instance it doesn't load the CPU much to move around blocks in RAM...

To check if it is a CPU issue another test is used. Something that does a lot of calculations but doesn't address memory or harddrive at all.

The idea is to test everything in isolation and see when the error occours.

About FSB multp lock - you could try changing the FSB speed then. That would under/overclock the thing. As a matter of fact, my system works very unstable at the standard speed I got it with from the start, it has to run a little overclocked to run perfectly (weird, I know...), I have matched it down to a problem with sync to the HDD controller when running in certain speeds.

Post:
You can't test the stability by letting it run iddle - nothing will happen then unless your system is REALLY screwed up.

It sounds like the memory or something can't keep up when being used 110% percent - have you tried running memtest86 to see if there is a problem? You can burn it to a CD and boot from that...
If it freezes during memtest and doesn't print any errors then something is not right.

Is the system overclocked? What frequency rate and settings do you run the RAM at?

Post:
It means that your host trashed a few models while trying to get one working - just wait a day (or untill midnight local server time actually) and the problem will go away.
10) Message boards : Number crunching : Computer performance when running models (Message 5174)
Posted 10 Oct 2004 by old_user73
Post:
In your case I would make BOINC run only 1 model at a time. It will complete that one faster than when running 2 and you won't have to think about starting and stopping stuff.

When you alter you settings to 1-model-only-mode the client will wait untill next trickle (or untill you press "update prefs") and will then pause model 2 untill model 1 is finished - so you won't loose any work.
11) Questions and Answers : Unix/Linux : Model crashing...is it me? (Message 4565)

Post:
Ok, problem solved!

It turned out to be a problem in the 2.6.5-gentoo-r1 kernel scheduler (I guess). Updating to the new 2.6.8-gentoo-r4 solved all problems! =)
12) Questions and Answers : Preferences : Problems Editing \'Account Info\' (Message 4148)
Posted 15 Sep 2004 by old_user73
Post:
Just for the record. This behavior has now been fixed - there is now a "Reset forum preferences"-button that you can press if your signature somehow affected the layout of the preferences page.
You can find it under "your account -&gt; Forum preferences -&gt; Reset"

Avatars are hosted directly on the project server and are (usually) streamed using the same connection that the html page was downloaded with (ie. pretty fast).
Signatures are on different 3rd party servers. I guess it would be a bad idea for the projects to be responsible for the caching. Actually if the 3rd party sites make their signatures in the right way they will not slow down the page loading at all. Only BOINC.dk does this at the moment (correct me if I'm wrong here, I'm possibly pretty biased...).
14) Questions and Answers : Unix/Linux : Account info (Message 3127)
Posted 6 Sep 2004 by old_user73
Post:
You probably entered a signature that was too long. If it screwed up your account page you can reset it <a href="edit_user_info_action.php">here</a> - Please remember to re-enter your username and location details again afterwards.

In the new version of the serverside BOINC code there will be a button to reset your signature.
15) Message boards : Number crunching : Unexpected problem downloading files (Message 2961)
Posted 4 Sep 2004 by old_user73
Post:
&gt; As it turned out, I downloaded the 4.05 from a mirror on the CP site, the exe
&gt; file was named mirror.exe.

Interesting. Exactly what browser did you use and what link?

&gt; When I went to P@H and downloaded the 4.05 that is named
&gt; boinc_4.05_windows_intelx86.exe and installed it over the other client,
&gt; all my problems went away.

This may as well have something to do with the fact that you reinitialized the files by reinstalling, not so much that you used a different binary. I guess there will be a better retry function in some future BOINC client as the current one does not _really_ retry on failed downloads.
16) Message boards : Number crunching : Time slicing question (Message 2490)
Posted 1 Sep 2004 by old_user73
Post:
&gt; What makes it worse, is that this is not apparently documented anywhere
&gt; except in the forum threads.

At least to some degree it is documented here:
<a href="http://boinc.berkeley.edu/client_sched.php">http://boinc.berkeley.edu/client_sched.php</a>

At some point it wasn't depending on RAC but the local cpu recent average debt, dunno how it works now, though.

Hopefully, at some point, the preemptive scheduler will take checkpointing into account when stopping WUs. How to do this hasn't been fully planned yet but it surely sounds like a good idea for everyone.
18) Message boards : Cafe CPDN : Clickable Links (Message 2195)
Posted 30 Aug 2004 by old_user73
Post:
&gt; Just one gripe about this forum, can it be set so clickable links open in a
&gt; new page, keeps p*****g me off when I forget to hold the shift key when I
&gt; click on a link.
&gt; Right got that off my chest :)

I'll add that little note to my personal todo list.
I'm very slowly redoing parts of the forum to support more of the stuff from phpBB (avatars, user desciptions, moderation stuff, beter quoting, general speedup, bb-code etc.)
Already you can use signatures in your posts.

&gt; This is not the friendliest of boards to use in a number of respects. [...]
&gt; if anyone wants to design a better one they are free to try.

This board, as well as everything else related to BOINC at the moment, is a work-in-progress thing. So they are pretty serious about it when they say "Please give us a helping hand" - which is how it should be understood.

The basic idea is to make a board that is easy to use and yet has enough powerfull capabilities to keep the more hardcore users happy.

So feel free to help - if you (the general you - not directed at anyone in particular) can't code then you can still help out by being a bit more positive about it, and perhaps by supplying ideas and suggestions to how things could be done better in the future. =)

Seen this once as well on LHC so maybe it is not just the CPDN client that is too sensitive. Haven't been able to reproduce it though.

As a parallel question: Are there any plans on publishing the source code for the application so that users can compile for their own weird systems (Playstation 2, my DVD player etc...) and with their own crazy CPU specific optimizations...or?
