Interesting stuff. I would like to know if any Mac has ever completed a model with 7 in the application version number.

[Edit: I mean the CPDN version number not the BOINC Manager version number.]


Ahh, I think I might have misunderstood. Yes that would indeed be interesting. Currently the version number is not parsed, added to the todo list.

Far from perfect, but made the following hack: It only looks at the "UK Met Office HadCM3 short" application (no version number specified)
http://ob.cakebox.net/cpdn_status/cpdn_tasks_short.html
(Currently not configured to update automatically)

No tasks where found successful on any of the macs that the script looked at. The "Total failure" was 12 % and the "Total success" was 0 % for darwin. (As the table at the bottom tries to show.).

A note on the choice in computers to analyse should be made, as it will bias the results considerably:
- First the 20 top hosts are visited http://climateapps2.oerc.ox.ac.uk/cpdnboinc/top_hosts.php
- Then the remaining 30 hosts are chosen at random from the "discovered" wingmenn.

This means that if there is a single mac out there that complete all of its short models, it will not show up as a wingmann for any other tasks (since cpdn does not use redundancy), and hence not be visited (assuming it is not in the top 20 list).

There are of course a number of ways to improve this algorithm...

In an attempt to look at the operating system dependency for failed model runs I added another chart (bottom):
http://ob.cakebox.net/cpdn_status/cpdn_tasks.html

The chart is based on wus where one computer has reported it as "Completed", while others have reported "Error while computing". Note that currently, 49% of analysed wus (of this type) has failed on windows, but later succeeded on windows, so no clear trend there. But the total number of succeeded on Darwin (mac) is terribly low, since the short wus seem to fail on macs.

Ideas for improvements are welcome.

I am happy to announce a new service:
http://ob.cakebox.net/cpdn_status/cpdn_tasks.html
This will run in addition to
http://ob.cakebox.net/cpdn_status/server_status.html
which is discussed here: http://climateapps2.oerc.ox.ac.uk/cpdnboinc/forum_thread.php?id=7778

One of the features that I have been thinking about is to allow you to filter the data, by e.g. operating system, boinc version, runtime, application... I am just not sure how to implement it. The simplest would be to pre-code some charts, is there a particular "breakdown" that you would like to see? For instance I see "runtime before failure" is being discussed in the forum, interesting?

The description could be better, if anyone understands it, feel free to suggest a better one.

Let me know what you think!

Please note: I have asked Jonathan Miller if the script puts any strain on the cpdn server, and I am waiting for a response. (I am guessing the answer will be no).

Very good! I would love more references though. Not just the climate-science-resources page, but footnotes after sentences/paragraphs.

Hi! The charts should now be back up again.

There is still a gap between 11. july and 17. july which I was unable to merge, but I will have another look later.

Yes, the chart has becomes stuck. The data is being recorded but due to a change at climateprediction the chart is not updating. I need to do a rewrite for this to work, might take a while.

chavk: Could you confirm that the chart has disappeared? What browser/OS?

I am seeing the slow loading of the charts myself. Probably caused by the, by now rather large, number of datapoints. It is due for a rewrite anyway, so I will probably try to reduce the number of old datapoints showing (by reducing number of points in the linear regions of the charts). Or just chop away old data.

Thanks for the feedback.

Tullis -

Great job on the chart.

One minor tweak - since the graphs show local time when you drag a mouse over them, why not make the title at the top local time instead of Norway time?

Or just make everything UTC?



Hi! Fixed the timezone irregularities. I tried javascripts toLocaleString, which played nicely with firefox, but displayed US time in chrome. So the title now uses toUTCString() which will hopefully play nicely across browsers and borders. The charts are still local.

In other news: I was contacted by a CPDN system administrator about giving the above service a more official status, I sent a positive reply but have not heard back. Will let you know how it goes.

Except that all of the ~60 000 tasks now seems to have been pulled?
http://ob.cakebox.net/cpdn_status/server_status.html

Or is this just temporary while they are updated to this new version?

Yes, a new application "hadam3pm2 (Global only model with MOSES II land scheme) (Linux and Mac only) (currently no graphics)" seems to have appeared. I knew this would create trouble since not all of the code handles this well. I will fix it at some point, but am currently swamped in other work, so don't hold your breath.

I might post the code on github or similar if anyone is interested in tinkering with it (python code).

Hmm, I actually found a syntax error which was affecting only the In progress part, hopefully IE likes the page a bit more now.

It still doesn't work. There's one difference with https://code.google.com/p/google-visualization-api-issues/issues/detail?id=936: it's before the head element instead of inside it. I don't know if that's important.


Arg, fixed.

Oh, and could you:
Would you mind looking at:
https://developers.google.com/chart/interactive/docs/gallery
If the "Line Chart" there is not visible, then I will just give up on IE8...

I searched for "<meta" but didn't find it. You made meta a property of an html element instead of a separate element as described in https://code.google.com/p/google-visualization-api-issues/issues/detail?id=936.


Vops, could you try again, it should now be:
<html lang="en">
<meta content="IE=edge,chrome=1" http-equiv="X-UA-Compatible">

I use Firefox, not IE.

The only part of our Service Status page that's intermittent, and hasn't worked at all for a LONG time is the bar chart under WU status.



I hope we are not talking about the same thing, the discussion is around my server status page, which can be found here:
http://ob.cakebox.net/cpdn_status/server_status.html
This page has never featured a bar chart.

@Les Bayliss Yes: The problem seems to be isolated to Internet Explorer (IE) 8, are you saying you have IE8 and can see all of the graphs?

The second line of the source should read
<html lang="en" meta content="IE=edge,chrome=1" http-equiv="X-UA-Compatible">

It might not have done so if you check right after I posted, but it should be there now.
