Message 695704 - Posted: 29 Dec 2007, 18:17:03 UTC

I has a thread going earlier in the year with issues about 'Bionic' Boinc and seti@home taking up 'all' the CPU time to the point of even timing out my DSL internet line.

I had to quit using it after quite a few years of using Seti classic as my screen saver in Windows.

I had no joy the last time I posted and had to drop it again.

I just got a new monitor and video card and found a bad ram chip so figured I would try again.

No joy, it still won't unlatch my CPU and slows the computer down to nothing. I have to go in and hit the suspend button or reboot.

I have it set so I manually have to turn on the client and manager right now because I don't wan't

I am trying the version 5.10.08 on Ubuntu Linux with 503M ram, 502 swap, Pentium III (Coppermine) 733 mhz and tons of disk space.

Hey I like it that the graphics button finally works and would love to try and tag that as a screen saver, but....

I was not alone, tons of others posted about having the same trouble and likely just gave up like me also.

Is there any fix yet?

As the symthoms you have written, and from the symthoms from your previous post, I am still think that there is a hardware problem.

Have you tried to let a complete hardware test suite running and verfied that your system is OK ?

Well the benchmarks used to run at "normal" priority so they could theoretically cause problems. But they only run the first time you start up BOINC and then once every 2 weeks or so. They also only last for a couple of seconds, maybe a minute or two on an older P3. However this behavior has changed in the past few months. The benchmarks should now run at idle priority - just like the science apps so CPU time should be yielded as soon as anything else needs it.

Have you tried running the Prime95 torture test for a while and does it cause the same behavior?

Also, since version 5.6 you can give BOINC a maximum % of CPU time it is allowed to use. Setting this to anything under 100% will force BOINC to pause and give up CPU time even if nothing else needs it. This setting is under the "Computing preferences" section in your account.

Yes, I had video card and USB mouse issues, both were changed again yesterday plus more RAM was added. I let linux mem program go at the now 1G ram with no errors.

I changed my preferences to have Seti only use 50% of the CPU both here and in my PC, reset the projects and updated the preferences.

The Seti program will not unlatch and will not use less than the whole processor.

How do you know it is seti not letting go of the CPU instead of the computer just locking up? Also, is it an immediate thing or does it take a few minutes before things break?

I would still suggest running the Prime95 torture test for a while. It will generate the same type of load on the CPU as seti.

Will that program also 'supposedly' unlatch the CPU when the computer is in use?

Otherwise.... A load test is a load test. That prime site has been too tied up to get the cruncher by the by and their mirror is gone.

OK, just a few minutes ago I was on a webpage trying to reload the page and it was hanging and hanging, so I went to boinc and suspended the seti and instantly the CPU monitor went to low and the web page refreshed, instantly! This happens every time something is hanging.

The boinc or seti program is still trying to use 100% of my CPU and I have it turned to 50% both online and at home, let alone it won't let go when my PC is in use.

I can post a 'top' screen shot to show you if you would like. I took one when it jammed up the last time as mentioned above.

This is excatly the point we try to find out.

Yes please, one top with running SETI and one in idle. Also the output of a "vmstat 5" with a running system and a idle system would be nice.

Btw. have you turned of the power management on your system which can cause that the CPU would be clocked down - some Linuxes has a daemon for this.

No I haven't looked at the power yet. (edit) Looked, the cpu is/was set to never power down, only the monitor powers down. I run Ubuntu Linux.

I now have 1.5G Ram and here are the top and vmstat and free screen grabs before and after.

For some reason, the way I post these figures in columns isn't showing up in the finished product?

Thanks for the output. I think it looks OK on the first view.

What excatly do you mean with "The program just will not unlatch the CPU." ?

Is the system permanently unusable if BOINC and SETI is running or is it only permanently ?
What behavior do you have, if you are running prime95 ?
Could you please excatly describe the slowdown. What actions are slowed down. - Eventualy a output series from the "vmstat 5" of such a slowdown would be helpfull.

With powermanagement, I meaned the Ubuntu specific. Ubuntu has a daemon which adjusts the clock, if no processes are running and clocks down your CPU. But I read here a posting, that it could happens, that ubuntu did not detect BOINC as running process and clocks down the CPU. But, I have not found this posting again. So I hope that one of the Ubuntu/Linux guys have an idea.
Anyway, the output from "cat /proc/cpuinfo" would also be nice.

The Seti program combined with the boincmgr want 100% of my CPU power. They will not relinquish control when 'I' want to use the computer, like right now.

This causes my other programs, like Firefox to literally hang with the 'waiting for connection' icon revolving.

When I go into boincmgr and suspend the project, the CPU gets let loose and Forefox 'instantly' finishes loading the page.

This happens both with Firefox and my Usenet program Thunderbird.

I have a smaller window for boincmgr so can see the underneath program start working and finish instantly after I suspend boinc's project.

Sorry, but this just isn't acceptable behavior.

Umm see above, the computer works proper with boinc in suspend mode or just not turned on, otherwise it messes up fairly soon.


What behavior do you have, if you are running prime95 ?


I have not been able to get prime95, their links are down.


Could you please excatly describe the slowdown. What actions are slowed down. - Eventualy a output series from the "vmstat 5" of such a slowdown would be helpfull.


That is the second vmstat 5 copy in my last post, but I didn't have Firefox and Thunderbird running.

Thanks for your time.

I also was hit back with the first generations of Boinc and my Windows 98 with the same issues and had to stop using it in Windows. I used Classic for a lot of years under a couple email names.

I was really hoping the bug was 'actually' fixed when I got an email implying it last year because I am now using Linux.

What excatly do you mean with "The program just will not unlatch the CPU." ?


The Seti program combined with the boincmgr want 100% of my CPU power. They will not relinquish control when 'I' want to use the computer, like right now.

This causes my other programs, like Firefox to literally hang with the 'waiting for connection' icon revolving.

When I go into boincmgr and suspend the project, the CPU gets let loose and Forefox 'instantly' finishes loading the page.

This happens both with Firefox and my Usenet program Thunderbird.

I have a smaller window for boincmgr so can see the underneath program start working and finish instantly after I suspend boinc's project.

This shows your problem a little bit in a other view.
Is the slowdown only on network access like you have bescribed, or is is also if you start and using other programms and working with the GUI ?


Sorry, but this just isn't acceptable behavior.

As I have explained you in my previos postings in the other threads : it is ok that SETI uses 100 % CPU, the process is running with the lowest prio so your other processes like FF, TB,.. should get the CPU if it need it. The slowown is not normal and we must search for the cause.
But your previous problem describtion was very unprecise. We have look closer to the problem and analyse it and search for the cause.

[
Is the system permanently unusable if BOINC and SETI is running or is it only permanently ?


Umm see above, the computer works proper with boinc in suspend mode or just not turned on, otherwise it messes up fairly soon.

This is not what I have meaned. I meaned if you running BOINC, did this behavior occurs permanently or only tempoarly ?

Which bug excactly do you mean ?
Whas this the same hardware like on the Linux system with the problem ? - If yes, I think that you have a hardware problem.

Edit: I had no problem to download prime95. Alternativ... google shows about 74000 results for prime95, the first 20 was alternative download mirrors.

I don't work with the GUI often, I just use those two programs mostly and it hits the network connection.

I am a Usenet user from 'way' back and barely use the WWW so when my 'text only' Usenet groups and their reader program hangs in space because of some piece of GUI software that isn't even 'supposed' to be running, it just well isn't acceptable. Netscape Communicator got locked up as well as Thunderbird now.

It is 'supposed' to 'shut' down, not maybe 'give me space' to work!

I don't know really. I get mad at it and don't bother to wait until it resolves, because the first few times gave me a DSL timeout, so I just go and suspend it.



Which bug excactly do you mean ?


The first generations of Boinc had a bug that wouldn't allow the CPU use settings in the preferences to work. I got an email back in early 07 I think it was implying the bug was fixed.


Whas this the same hardware like on the Linux system with the problem ? - If yes, I think that you have a hardware problem.


Only the same ASUS CUV4X motherboard, all the add ons and memory chips are new, including a new power supply.

I only used the link provided earlier the other day, haven't tried since, have been busy setting up hardware. I will try again and see if that program will unlatch the CPU.

Ok, all the links my Google shows for a Linux download lead to the same page and it is down. Yup, 'tons ' of links that all point the same place....

I just spent a half hour trying, that's enough.

There seems to be something wrong as I write this. I just tried grabbing both mprime2414.tar.gz and sprime2414.tar.gz from http://www.mersenne.org/freesoft.htm but in each case the Firefox downloads window showed 'waiting' for a few minutes and then 'completed' - but nothing had actually been downloaded.
The Russian mirror site mentioned at the above site fails to resolve - it seems to no longer exist.

As to your main problem - I do find it a little suspicious that this is the same motherboard which gave similar 'heavy load' problems with BOINC when it was running under Windows. I'm inclined to agree with Dotsch that there's a fundamental hardware problem lurking at the back of all this.

For what it's worth, I have BOINC running perfectly well on an ancient Intel 440BX-based motherboard with 1GB RAM and a PIII CPU. Actually, it's a card adapter carrying the PIII since this motherboard only has a Pentium II slot. I did say it was ancient! :)
I also use this machine as an alternate "browsing base", plus a few other things, yet it's never shown anything like the sort of performance hit you describe. It's left running BOINC 24/7. The OS is a fairly old SUSE 9.3 release. Well, it ain't broke so I ain't fixing it...

If left to its own devices, BOINC will always try to obtain 100% CPU usage (really, like almost any other application would typically want to do) but bear in mind that when using things like 'top' to display loadings, you're only getting a tiny snapshot every second or so. All the time, running processes are given access to resources (and have them taken away) very quickly so what appears to be a constant high load isn't necessarily so. Also, the resource management of Linux is such that as other tasks require more CPU time or other resources, access is granted very efficiently and in a very controlled/controllable way.

It's probably only because of this good behaviour that I'm able to run BOINC on this venerable box - when running Windows98 (on another dusty old partition) and not doing very much at all, it's horribly sluggish.

Just my $0.2, and I hope that whatever's going wrong is quickly nailed.

But 'there' is the main trouble, Boinc will not unlatch the CPU like it is instructed to do in the preferences or 'only' actually 'use' the 50% max of the CPU the preferences are set at!

Load stress is something all together different and I would have 'no' load issues, perceived or real if the program would behave as it is supposed to do and just shut off when 'I' want to use 'my' computer.


If left to its own devices, BOINC will always try to obtain 100% CPU usage


It is 'not' being left to it's own devices, I am insisting it use only 50% of my CPU and insisting it shuts down when I am using the computer via the preferences both here and in my PC.


Just my $0.2, and I hope that whatever's going wrong is quickly nailed.

Hmm, but there's the odd thing: I'm running the same version as you on the same CPU and in less RAM - yet because mine is behaving fine, I really don't think it's BOINC which has the problem.
A few posts back you gave this 'top' output (edited) when running BOINC/seti:

This is running under KDE and is started manually from a desktop icon with just 'run_manager' as the command component, from within the BOINC installation directory off my home directory. I just installed it with the default GUI stuff as-is, and made no other tweaks to the installation. The machine is generally left running so I've not bothered with any auto-start scripting.
There's also no unusual or heavy network use as a result of running BOINC/seti - only what I might be getting up to (nothing else, apart from a few shell windows waiting for input at the time of this 'top' output).

Load stress is something all together different

Sorry, that was my loose description. I just meant the sort of 'grind to a halt' thing you've described when running BOINC/seti.

Odd...

Could you please try it out. It is very important to know what excatly is slowed down when BOINC and SETI is active !

Could you please change to the BOINC directory and issue and post the output from the command : "grep cpu_usage_limit global_prefs_override.xml".

Yours also appears to be broken 'if' you also have it set to shut off when 'you' are using the machine. It isn't unlatching your CPU either.

I could 'very' well be that my hardware has issues with the sharing, but it wouldn't have any issues if the program would follow it's 'preferences' and shut off!
