Hi, I\'ve just started trying to use climateprecition on my Linux box and the models crash soon after processing starts. I\'ve tried two different Boinc clients, both exhibit the same symptoms so I don\'t think it\'s the client rather the work unit that is being run. Here are two examples:

http://climateapps2.oucs.ox.ac.uk/cpdnboinc/result.php?resultid=8140535
http://climateapps2.oucs.ox.ac.uk/cpdnboinc/result.php?resultid=7647325

This is being run from the command line since I don\'t have any graphics installed on the machine. In terms of the build, its\' a fairly old Suse 8.2 distro but which has had quite a few updates applied over the years hence I\'ve been using the Boinc clients for \"older\" Linux versions.

Cheers,


Jon.

I am running climateprediction.net on SuSE Linux 10.3 and BOINC 5.10.45. I am running a WU similar to yours and it gives no graphics, while CPDN Beta shows a graphic window. I would suggest to you to download OpenSuse 11 and install it, maybe after saving your BOINC directory to a flash cartridge, as I do on a weekly basis. I am running six BOINC projects on an AMD Opteron 1210 at 1.8 GHz and meeting all deadlines. Cheers.

Graphics shouldn\'t matter, the command line client doesn\'t require that.

It might be a RAM shortage, old HadSM3 versions did run on 256MB but I\'m not sure about the current ones.

Possible... RAM is pretty much maxed out at this point although there is half a gig of swap space and that\'s not been touched. I could try and stick some more memory in there.

A full distro upgrade isn\'t really on the cards, there\'s too many bits I\'ve had tweaked to go through the pain off doing again...

it\'s now got 1gig of RAM fitted but no change:

http://climateapps2.oucs.ox.ac.uk/cpdnboinc/result.php?resultid=8130103

Is there any other diagnostic information it produces rather than just \"model crash\"?

Sorry to insist. Update your distro. I am running six projects on SuSE Linux 10.3 with no errors.

... the only diagnostic information we can see is by expanding the \'stderr out\' field on the \'Task details\' page on the Web site, which shows all your models crashing in the same way (with both client versions).

Other AMD/Linux machines have made further progress in those work units, so it looks to be a machine configuration problem of some kind. I know nothing about Linux, so can\'t really suggest anything useful.

ok, I suspect it\'s probably a shared library or similar being too out of date for the binaries to deal with so I\'ll just have to abandon it as a bad job since I can\'t really afford the time/pain of attempting a full upgrade for this one issue.

cheers,

I may post this question on the other forum since there seems to be a bit more on model crashes etc. but just found this on the BOINC FAQ wrt to the error codes being spat out of stderr:

When running a 64-bit Linux on a project that sends 32-bit applications only, you can run into results erroring out with process exited with code 22.

The explanation for this is that 32-bit binaries don\'t just work on every 64-bit Linux. If for example you install a fresh Ubuntu 6.10 or 7.04, 32-bit binaries won\'t work. They are not even recognized as valid executables. You first have to install the ia32 package and dependent packages. Further, for programs that link with the graphic library, you will manually have to copy a 32-bit libglut library to the usr/lib32 directory.

If after this you still get client errors, post on the forums of the project that you have this problem and ran ldd on the executable in the projects directory to see what libraries are missing. Post which libraries these are and ask for instructions on how to get them.


Which makes little sense to me because I\'m running a 32-bit version of Linux....

I was going to suggest that too....

But I used to get the error 22 before on my older system. I figured out it was due to file permissions/owners. I couldn\'t figure out what the permission should be (other than 0777 everything), so I ended up resetting the project, exiting BOINC, deleting the climateprediction.net folder under BOINC/projects, and then restarting BOINC. The next task downloaded worked fine.

Also, if you\'re not already, I recommend the 5.8.16 version of BOINC for older distros. It\'s run lots of climate models for me without much of a problem.
