Message 16346 - Posted: 1 Oct 2005, 1:56:48 UTC

I have a Sulphur on a P4 3.0GHz HT with Windows XP Home that has made it to Phase 2.

I had a Sulphur waiting on an AMD Athlon 64 2800+ running Linux 2.6.10, Boinc 4.19 (optimized by Ned Slider).

I was messing with the Linux machine and changed to Boinc 4.43. I have changed back and forth before with no ill effects. The slab wu was early in Phase 2. So when Boinc 4.43 woke up, it went to work on the wu with the earliest deadline, which was the sulphur. I kept the messages, in case they are of interest to anyone, but it quit with an error. Then it went back to crunching the slab, and it seems to be fine.

I stuck with optimized 4.19 because the benchmarks with 4.43 were so low. It turns out the timesteps with 4.43 are 2.2 sec compared to 2.4 sec. So at least for CPDN, optimized BOINC doesn\'t seem to help me.

No, I haven\'t been backing up. But I guess I need to start doing that. If I had, I could have suspended that sulphur cycle and tried running it under 4.19 when the time came.

I wanted to try 4.43 so I would have the ability to drain off the other projects wu\'s instead of trashing them by detaching, since 4.19 doesn\'t have as many features. I didn\'t think I would have got the sulphur done in time sharing with other projects.

Thanks for listening and Happy Crunching.

I would be interested in the error message. I, and several other people, had difficulty with 4.43 in Linux and sulphur associated with the BOINC benchmarks.

I stuck with optimized 4.19 because the benchmarks with 4.43 were so low. It turns out the timesteps with 4.43 are 2.2 sec compared to 2.4 sec. So at least for CPDN, optimized BOINC doesn\'t seem to help me.

The version of BOINC, optimized or not, should have miniscule impact on CPDN performance. Maybe .02 sec/TS, if that. Certainly not .2 sec/TS.

I wanted to try 4.43 so I would have the ability to drain off the other projects wu\'s instead of trashing them by detaching, since 4.19 doesn\'t have as many features. I didn\'t think I would have got the sulphur done in time sharing with other projects.

Yes, 4.43 does have some nice features compared to 4.19, but it also has some problems with CPDN. Hopefully the next version of BOINC will iron those out.

A optimized BOINC isn\'t usefull for CPDN as credits are not claimed according to benchmarks. And an optimized BOINC doesn\'t accelerate the speed of the applications, it\'s just for credits.
Using 4.19 in Sulphur is not a good idea because you can\'t upload results at the end of the phase.

Here are the messages. 2nqc is the slab that I had been running with 4.19, and 494c is the sulphur cycle. I have also noticed that there appear to be about three timesteps in a row missing from 2nqc, so I am not so sure 4.43 took up where 4.19 left off. I promise not to play with it anymore in the middle of a model without backing up.

These were the error messages on the result page for that WU:

a zipfile, or it constitutes one disk of a multi-part archive. In the

I have never seen these before so I\'m afraid I can\'t be much help.

Well, if nothing else I would like to add the error logs to my collection for possibly adding to the Wiki ...

Can you zip up the *.TXT and OLD files and send them to p.d.buck@comcast.net ...

Thanks!

I guess not, I am too dumb. Not sure what I am doing wrong getting Ark to zip things. I need to do some more reading.

I don\'t see any OLD files in Linux. I see them in the Windows BOINC folder. In Linux, there are txt files in the slots folders. I do have \"hidden files\" turned on. My poor little 494c folder in Projects only has an xml file in it. I put it in a word document and it is only three or four pages long.

Hmm, You should have several TXT files ...

For example, in my boinc directory on OS-X I have:

-rw-r--r--    1 paulbuck  admin   464817 Oct  1 23:28 stderrdae.txt
-rw-r--r--    1 paulbuck  admin    22545 Sep 28 11:30 stderrgui.txt

-rw-r--r--    1 paulbuck  admin  1969502 Oct  1 23:28 stdoutdae.txt
-rw-r--r--    1 paulbuck  admin        9 Sep  8 06:42 stdoutgui.txt
G5a:/Library/application support/boinc data paulbuck$ 


These are the files I am interested in ...

Not sure where they are \"hidden\" in Linux as I don\'t have a linux system (yet).

In Linux, the log files are usually in the Wu folder( ~/BOINC/projects/climateprediction.net/xxxx_yyyyyyyyyy ) and in the slot folder (~/BOINC/slots/X)

And all the brackets were replaced with [].

and there is a stderr.txt file in slots that just says

\"no heartbeat from core client\" over and over again. Perhaps if I had collected the stderr.txt right after the model crash I could have had something useful.

Message 16422 - Posted: 4 Oct 2005, 11:45:24 UTC

Stealing liberally from the Wiki ... the text for that message (we have most of them, but, always looking for one more):

========
This error is caused by one or more of the running processes, the BOINC Daemon that make up the BOINC Client Software on the Participant\'s Computer has stopped running (it \"crashed\").

In other words, something real bad happened. The usual suspect is the BOINC Daemon, but it can also be from the failure of the Science Application.

Now, for those that want to know more, a \"heart-beat\" (or heartbeat) is a periodic message sent from one software component to another telling that other software component, \"I am alive and well!\". In the BOINC Client Software we have signals going from the Science Application to the BOINC Daemon, and a separate set of signals going in the other direction.

If the BOINC Daemon stops running, we want the Science Application to also stop, and vice versa. If one dies, the other should die also. These heart-beat signals are common in software systems where there are multiple components that run essentially independent of each other. They are just small messages and they are repeated every few minutes or so. So, they don\'t take much away from your hunt for maximum credit.

Courtesy of Walt Gribben (with minor edits by Paul):

This message means that the BOINC Client Software stopped communicating with the Science Application.

The BOINC Daemon sends a heartbeat message out so that the Science Application programs know its still alive and kicking. So if the messages stop, its supposed to mean that the BOINC Daemon isn\'t running anymore (perhaps it crashed?) and the Science Applications are also supposed to exit. Thats after they don\'t get a heartbeat message for 30 seconds. So, they print the \"no heartbeat\" error and exit. The Science Applications are using an exit code of zero to indicate there isn\'t any error, at least not with the Work Unit.

Later, the BOINC Daemon sees that the Science Application exited (zero status) but wasn\'t finished with the Work Unit (there is no finished file) so it restarts the Work Unit. And from where it left off, or at least from the last Checkpoint.

There might be a problem with BOINC Daemon to the Science Application communications, but its not all that serious. Some time is lost in restarting the Work Unit, but its not like it has to start from the beginning each time. After I saw the Work Units were completing in around the same time whether or not they got \"no heartbeat\" messages, I stopped looking into it.

==========

The log files are in the same directory that contains the \"slot\" directories and the main BOINC Client Software. If you are running one of the command line clients, then you have to use the UNIX redirects to write the files. It has been so long since I have run those that I do not recall the exact syntax. But, with the later client software there is no real reason not to run the \"graphical\" clients I don\'t know why they bother with the older CLI versions anymore ... but I digress ...

If you don\'t have the logs, you don\'t have the logs ... but it is strange ...

Paul,

Yes, that was my crashed sulphur cycle.

As to the heartbeat issue- when I look in the linux system monitor, boinc is listed as sleeping, while the science app is listed as running. If a process is sleeping does it still have a heartbeat? Or because it is sleeping, it doesn\'t send a heartbeat message, and thus the generation of all those heartbeat messages.

As to the heartbeat issue- when I look in the linux system monitor, boinc is listed as sleeping, while the science app is listed as running.

It\'s normal. Same thing on my machines.
Boinc must be running from time to time to communicate with the science apps, but else it\'s sleeping.
Edit: I checked in Ksysguard: CPU % of boinc is going to .25% every 1 minute.

Pam,

The BOINC Client/BOINC Daemon is and should be mostly asleep. if it is not, then there is a problem. In essence, as Arnaud said, the BOINC Daemon should be using 1% or less CPU in almost all cases (the BENCHMARK period is obviously one of the special cases).

In effect, the BOINC Daemon is like an operating system kernel, you need it, but you don\'t want it to take up too much time. However, if the BOINC Daemon dies, the science application has just lost its \"parent\" process. And one of the means that is used to determine death is the \"heart-beat\" exchange.

Not having studied that part of the code, and not haveing my own science application to test (yet) I cannot say for sure what other special cases could exist where you would lose the heartbeat. But, they SHOULD be rare. If you are getting this all the time, and the models are crashing, there is something going on ...

THis is why the logs are so important. You can tell a lot from the content. Like who died, when, sometimes ... :)

The point being, I don\'t know how/why you are not getting the log files which is why I asked if you were using the CLI version.

I had, for example, problems with CPDN on the PowerMac running OS-X ... turns out this is a \"known\" issue that is easily fixed but I did not pursue it hard enough ... looking at *MY* error messages in the result file got me the clue ... and *I* may be running again ... won\'t be real sure till I get past the first \"trickle\" ... but I do have an hour of run time ...

anyway ... I am not the best trouble-shooter, but if you are still having problems we can TRY to get you back on the air again ... first we have to get your logs back though ...
