Edit...** It appears that the sulphur 4.23 Linux model is completely unstable. The programmers know about it, but their time is consumed with finishing up development of the next experiment. Suggestion is to run other BOINC projects until this is fixed, or until the next experiment is released (Beta IS stable on Linux). Those running Linux sulphur 4.22 and previous should be relatively stable. **

Edit 2...** LS Diseño has figured out a way to revert from 4.23 to 4.21 and has instructions for doing so below. You may want to give this a try if you want to continue crunching sulphur with Linux. **

Edit 3...** The coupled model, hadcm3l, might now be downloaded from the climateprediction.net site. The model is stable, compared to sulphur 4.23 anyway, but some users still have troubles with it. It is essentially the same model as being run at the BBC site, and you may want to peruse the BBC Linux board if you run into problems.

A dual Xeon 2.8 GHz running FC3 was running two sulphur 4.23 models. Each of them crashed during June of 1818, shortly after the halfway point of phase 1. Nothing intelligible was found at the end of yabsd.out in either model to help determine why they crashed.

This PC has been very stable up until this point. The Results for this hostID are 1614429 and 1614592. Below is the terminal log of the last crash. Doesn\'t look like anything helpful in this logging.

This looks like a problem with 4.23 or the WUs.

I notice this near the start of the log:

quote

Error: Restart files for not found
unquote

I wonder if this is just a grammatical mistake, or does it mean that some part of the error code can\'t find the model name?

It sure is a hard slog to get Linux to complete a sulphur model. :(

edit
It looks like one has to include the word quote oneself.

Typically it has something like \"dataout/restart.year\" after the \"for\". But it was obvious that it had already rewound previously because it was moving along at 3.86 s/TS, when yesterday it was doing 3.45 s/TS.

My first two models on AMD XP also shows crashes.
The first one gave up after TS 113528 26/6/1817 04:00. It also had crash&rewinds after trickle 8 (TS 86416). Terminal log looks similar to geophi\'s and nothing looks special at the end of yabsd.out.
Model 1617143

The second one has had three crash@rewinds now but is still running.
It looked like this on the terminal:

This is HostID=3880, nice and reliable.
I took a copy of yabsd.out but I don\'t know if there\'s something special there,
two warning messages looks like this:
INITTIME: Warning- New STEP doesn\'t match old value
Internal model id 1 Old= 103536 New= 103680

So guess this one will finish too in a couple of hours. Something special I should monitor?

The model on host 3880 gave up at TS 112422 03/06 1817 03:00, model 1622417.

The bottom of yabsd.out looks like this:
Model aborted with error code - 1 Routine and message:-
ATM_DYN : NEGATIVE THETA DETECTED.

Got the exact same error as you guys did. My model (running on a Red Hat Linux), died around timestep 113,000. Same error log as mentioned by you.

My last backup was before the crash. Now I have a backup with the crashed model. The crash seems to be reproducible, so running from the first backup you can reproduce the crash very easily.

So...

I would like to announce that I am keeping both archives (from before and after the crash), and if the developers need them for reproducing and debugging the error, I would gladly upload the data. If it could help to take a look at them, just give me an FTP connection on some server or something similar, and I shall upload the two backups. They are around 160 Mb each.

Cheers,
Stefan.

Two more sulphur 4.23 models have failed on the dual Xeon between 10,000 and 14000 timesteps into the first phase. Not good. I\'m suspending sulphur on that PC now.

Judging by the crashes everyone seems to be getting, it seems that sulphur no longer works on Linux.

Thus I have suspended all of my Linux workstations until the developers find the problem. Switched these machines to LHC@Home in the meantime...

Hope the problem will be fixed soon. :((

My fourth model, 1638004, ended on TS 114329 12/07/1817 20:30.
The fifth model, 1631205, gave up on TS 113686 29/06/1817 11:00. This was on a nice XP 2500+ at stock speed.

All of my misbehaving models were created 23 Dec.
Got me a newer one now from 16 Jan.

Oh..
I wish they could switch to slabs then, just for Linux?
I only have 1.5 old slabs here now to feed three machines until the HadCM3L launch. (No, I can\'t switch to Windows)

Same problem for the third time with Sulphur on my Opteron244 SuSE 10.0 64-bit.

The problem arose after the 10-th trickle the first 2 times and after the 9-th the third time

A fourth file is still running but if it crashes as well, I\'ll stop calculating on Climateprediction files foe the moment

The 161 errors are a \'red herring\'. If there is any record of the REAL reason for the failure, it will be near the bottom of the file: yabsd.out, which is in the dataout folder of the model.

The problem arose after the 10-th trickle the first 2 times and after the 9-th the third time

Yep, that sounds like the 4.23 problem. All five of of my failures crashed between 9 and 13 trickles into the run.

Hi,

same errors here on an Athlon 1500+ and 3000+ both running Ubuntu Breezy 5.10.

Can\'t post the actual 161 error message, as the pasted text confuses the BBcode so only part of the error message gets displayed...

The yabsd.out file contains a lot of cryptic stuff, but what I can make out are warnings about computations giving negative values...

Three more crashed models around trickle 10.
That\'s a total of eight now on four different machines.

Edit: got a new one created today, but this is the last try.

Although Tolu and Carl know about this problem, I have a feeling it won\'t be fixed in a new sulphur version until after the launch of the coupled model experiment. That is where their time is going now.
