I think this may be a lot worse than the Australian server being down.
Or, in the case of the 2 models listed, the re-start server at Oxford.

That computer has a LOT of "still running" models showing on it's list from way back.
1263799

So, some questions:

Is that computer also running work for other projects?
Are there 12 climate models showing in it's Tasks tab?
What message(s) is/are showing in the Event Log when there's an upload attempt?

And I think that you should start a new thread for this, as it may take several posts to sort out.

Les,
Sorry, but I could not figure out how to start a new thread.
Answers at end.

1. Yes, the computer is also running work for other projects. PrimeGrid, World Community Grid, MilkyWay (GPU only), Rosetta, and Einstein (GPU only).
2. Yes, there are 12 climate models showing in the TASKs tab. Two have completed after 200 hours each (a week or so ago) and 10 more are in the QUEUE. It looks like about 300 compute hours left.
3. When I push the RETRY NOW button to upload the completed tasks, I get the sequence of messages:

A bit of (picky) terminology (which might help others; terms changed over CPDN's years) -- this is the 'current final' version:

Trickles are small files with minimal science, at Checkpoints, used to award credit (credit not held until the end, as with other projects) and keep the head shed updated on tasks' progress. They do not show in the log.

Task is a single job, in the queue or in progress.

Work Unit is the total of identical Tasks allowed in case initial and subsequent attempts fail; current number of attempts allowed is five.

For most recent Tasks, twelve .zip files go to servers in England, Oregon (US), or Australia. The last .zip, #13, goes to it's own server at Oxford. This is the restart file which allows the next increment in the sequence of years to be sent out. (We used to run 160-year HADcm3 tasks as a single task on one computer. After numerous complaints, the work was chopped into pieces -- shorter runs, with a penalty of longer uploads and downloads.)

This has been going on since yesterday evening and the zips are stuck in the transfer tab. Curiously I cannot find a folder in the projects folder in BOINC data that corresponds to the model that has been run. Is there a file missing somsewhere?

Alan

The description of what has happened needs to be very specific here, because it could be a BOINC "feature".

So: You said that the model had completed. Do you mean that it has Reported?
Because if so, that's the end of that model, as below.

**********

There's a situation where there's a problem with BOINC when some the servers are slow, or "down".
This is when the "Network" in the BOINC menu has been turned Off, and all zips / trickles from the point allowed to accumulate on the computer. If there is then a failure of the model at/near the end, BOINC gets a message of the failure, and flags it internally as such.

So, when the "Network" is turned back on, BOINC runs through it's ToDo list, (client_state.xml), which is to start sending back the trickles and the first 2 zips. Then it gets to the part where it has written that the model has failed, and begins to clear everything from it's ToDo list, so it sends back the error messages, and then deletes everything pertaining to that model.

At this point, all of the zips, (and trickles if they are still waiting on a slow server), suddenly disappear. You can see this happen if you're looking at the Transfers tab at the right moment.

Message 51220 - Posted: 14 Jan 2015, 19:16:35 UTC - in response to Message 51219.  

Another way of looking at it: BOINC regards a task as finished, dealt with, removable, when:

* either it has reached a successful completion and uploaded all its zip files.

* or it has exited abnormally with an error.

The second situation doesn't wait for uploads to complete before doing the housekeeping - the developers didn't consider the 'middle way' where the early, intermediate, data is still valuable, even if the task couldn't make it all the way through to the end.

Hi

The model is showing in the task tab as 100% on the progress. There are two zip files waiting in the transfer tab - since some time yesterday evening. Also two trickle files have been successfully uploaded. There is nothing in the stderr tab on the task on my account. Does this give you any clues. I was wondering if a server was down...

The task is still running ( ~ 61%) but BOINC cannot upload the trickle (for a few days).

I.e.:

To help the staff debug your problem, it should be said that what you've reported isn't a trickle problem. They look like

14/01/2015 04:40:32 | climateprediction.net | Sending scheduler request: To send trickle-up message.
14/01/2015 04:40:35 | climateprediction.net | Scheduler request completed

Yours is a data upload problem, and to solve it, we first need to know which upload server the file is being sent to.

The server for the hadcm3c-result-files (63 - 64 MB) has a "connect() failed" - I do not know the name of the server. (also the server for the hadcm3n-result-files ?!).

The server name will be listed in client_state.xml

1) Copy this file.
2) Paste it somewhere outside of the BOINC structure.
3) Open the copy with Notepad.
4) Search for the 4 character model name.
For this one of mine: hadam3p_eu_zwyt_2013_0_009436587_2, the 4 character name is zwyt

5) Keep searching until, a few lines below where you end up, you see the word upload_handler to the right of the string. (The line will be enclosed in upload_url at each end.)
6) Copy that upload line, and paste it here.
