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).

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.

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.]

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...

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.

Thanks, tullus. That rather confirms my prejudice. I know that my Mac can't run to completion any 7-series model - it would appear, for HADCM3S at least, that the problem is not particular to my machine but general to all Macs.

(I've flagged this on beta to the project staff, in case they replace HADAM3P/EU/ANZ with 7-series versions, in which case Mac users would be left with only HADCM3N to run - which is another kind of challenge!)

All my 7-series tasks for HADCM3S have come up with a compute error near the end of processing. Would it better not to accept any 7-series task on a Mac at the moment?
If so, should I abort any of these that are currently in my queue?

That is my belief. However, I haven't established that definitively for all Macs, just my own and the extension by tullus here. There's work in beta that might fix this soon, which will restore the full spectrum of models to Mac users and fix other problems as well. (That is of course to count one's beta chickens before they are hatched.)

Thanks Iain, that was my feeling too. Let's hope any new hatchlings are well bred.
