I had working graphics on Fedora 7. I did some updates a couple months ago via yum, and now starting graphics causes the hadcm3 executable to die!

Since I have no idea what package caused this, does someone know what log file or error file I can look at to determine what to do next? Or has anyone experienced this problem?

There are various log files that different components of the climate model can generate, look for files starting with stdout_ or stderr_ and ending with a .txt file extension. Usually in the work unit\'s own folder.

stderr_um.txt file was zero bytes. This was the only thing that looked like an error:

[starfox@localhost hadcm3inct_cmuo_1920_160_35869820]$ tail stdout_um4.txt
2035 points were -ve and the scaling factor has been reset to 1

I don\'t think that\'s related, that looks like a general output from the climate model rather than an actual crash dump.

Are you capturing stdout? (i.e., run_client & >capture_std_out.txt or something like that). That might show more info.

Could you provide a link to one of the crashed models so we can see if anything relevant is shown on the website? (Your computers are hidden so we can\'t find anything).

-- Edit:

Does the same happen on the new version of Slab (in Beta)? (climateapps1.oucx.ox.ac.uk/beta)

There\'s nothing indicating a crash in the boinc log files. Actually, BOINC thinks it\'s still running after starting graphics. The parent process doesn\'t die, just the child hadcm3 process. If I exit BOINC, it all terminates OK.

But here\'s is a sample of what happens when I have to kill BOINC after graphics hangs (just ignore the SETI tasks):

Here\'s the WU:
http://climateapps2.oucs.ox.ac.uk/cpdnboinc/workunit.php?wuid=6049348

And my specific task:
http://climateapps2.oucs.ox.ac.uk/cpdnboinc/result.php?resultid=6567767

If I don\'t display graphics, it seems to run OK so far.

I have not downloaded another slab model since finishing this one a few weeks ago:
http://climateapps2.oucs.ox.ac.uk/cpdnboinc/result.php?resultid=6826318

Also, both the slab model and this coupled model (as of a couple months ago) displayed graphics properly.

Not sure, but perhaps the updates a couple months ago broke some interaction with BOINC (at least the version you have). Perhaps try another yum update, and update to the latest version of BOINC?

OMG, I got graphics to work! You wouldn\'t believe what is was. It was file permissions! I did a chmod -R 0775 on the whole project folder and graphics work now! Silly me. Perhaps the system updates had nothing to do with it.

PS I wouldn\'t have found it except that I tried to download a slab model for testing. It errored out with code 22 -- file permissions! Bad news is I lost the new slab model at 0%, but the good news is the coupled model is working with graphics now. The CM should be done by Xmas.

Lucky you discovered that. It\'s a nuisance running a model without the graphics even though most of us only check up on them from time to time.
