27 tasks finished by MacBookPro Intel Core Duo 2.16 GHz running Darwin 9.8.0

Completed u series 6 v series 1
Error while computing 11 9
Totals 17 10

Only one was for year 599, and was a completed u series task.

2 v series In progress have been excluded as also have v series 2 ghosts, which are "in progress" due to a resetting of CPDN.

The BUFFIN errors happen when a FAMOUS task is removed from memory between generating a trickle and the next checkpoint. The task is restarted from the checkpoint before the trickle and the error is generated when a second attenmpt is made to post-process the data for the previous year. The errors are harmless.

This 'Workunit error - check skipped' message means nothing for CPDN because our models aren't validated in the same way as tasks from other projects. It's a confounded nuisance and must put some people off. I don't know whether Milo could get rid of it.

Similarly, on your model's workunit page we see 'Too many total results' which is another irrelevant message.

John

The only messages relevant to climate models are found in stderr, which is on the main model page.
As there aren't any error messages, and it says further up the page: Over Success Done, that particular model is just that; a success.

Thank you for the results of such a large number of models. Superficially this appears to mean a success rate of about 64% and a failure rate of about 36%. However, as the failures take less time to run because they crash before the end, the failure rate must be lower (if we mean the probability that any model will complete or fail).

I'm not sure how to calculate this.

Ideally the calculation would need to take into account whether on average the crashes occur at 50% completion (ie are equally likely to happen at any processing moment). I don't know this.

Maybe if you incorporate the CPU-time a better idea of failure rate can be gotten.

Looking at the stats for the first host of [B^S] mavau's list, the total CPU time spent on FAMOUS models comes to approximately 61 million seconds (60785865.05). About 48 million seconds of those (48398651.3) were spent on successfully completed models. Maybe it is fair to say that makes for a 80% success rate for that particular host? Those numbers are based on 87 models (55/32).
Or would you have to take into account the time spent if all models had completed successfully? In that case you'll get an about 63% success rate

I've been through my results in more detail.
First, some of my errors were successes on other platforms.

And here is a look at my completed models failing on other platforms/combinations.
This is not a full list. I've tried to exclude computers with constant failures, immediate failures...
I haven't checked every failure. I've noted a few disk errors on Windows 7 I hadn't seen before towards the end of the list.
Note the large number of invalid thetas on Darwin

An early failure I'd missed (application doesn't show in the right column).
Windows machines fail at the same point, Linux a little bit later, and Darwin succeeds.

The reason for the larger proportion of Darwin failures, is because the compiler used couldn't be set to not use SSE2 on Macs.
So, while Windows and Linux were eventually set to not use SSE2, and therefore be more stable, (but slower), Macs weren't.
(All of this was during testing on the beta site.)

Statistics is beset with problems.

I don’t think that I have ever seen a graph like that before. That is more than just a cold snap. It is more a glacial age. It looks more like the entire Earth was entering a snowball phase like what geologists think happened about 700 million years ago.
