1) Message boards : Number crunching : Uploading files fails (Message 62519)

Plenty of time yet.
They've only been running long enough for "weather", not for "climate." :)


OK, got an idea of length of these now. 32 months, one i5 at 3.3GHz has returned six out of 32 trickle ups so at least a couple of days till the fastest machines complete I would guestimate.

My first model has finished but not reported. The first two zips uploaded and cleared; the remainder, including the restart and 'out' file, occasionally upload to 100% and then revert to 0%.

My remote machines are the same - a couple of successful uploads and the remaining Zips retrying.

As if by magic, New Work Announcements - so the RAC decay is a problem for another day.

Though only for the computers that managed to grab some of them. ;)

... another 3150. Jump in!

There are 3,150 more Australia & New Zealand models added to the queue, at 50 km resolution and covering 32 months (batch list).

Climate change boosted Australia bushfire risk by at least 30%

This is in part based on CPDN models, according to World Weather Attribution: Attribution of the Australian bushfire risk to anthropogenic climate change.

The EAS version of this problem should now be over - files are uploading and models reporting.

This outage appears now to have cleared, as my EAS Zip files have uploaded and the model reported.

They think they have solved the problem. Let us know if you still have problems uploading the EAS files.

... mine have now cleared.

Note that the weekend seems to have already started: my Batch #866 EAS uploads are backed off.

Maybe with Microsoft pulling support for Windows 7 there will be people thinking of a PC upgrade - I am, though my current machine is perfectly alright for my own and CPDN’s normal purposes. I’ve tried Windows 10 upgrades but just get blue screens of death, so I can see why Microsoft recommends a new PC, though I don’t see why they couldn’t have worked a bit harder on the upgrades. A new machine with enough memory to run a virtual Linux should be easy enough: I’ll run Linux models on that when they’re available, keep my current Windows 7 machine until it becomes risky, and retire my oldest Windows 7 PC (which is already struggling).

It’s still the case that the area is present in the model name.

For the model wah2_pnw25_b1l9_199412_15_864_011989350_0 running on one of your PCs, for example, the “pnw25” means it’s Pacific North-West at 25 km resolution. The “_15_” means it runs for 15 model months. The “_864_” is the batch number.

There aren’t any graphics any more. However, there is a thread on this message board that describes the regions, as they appear from time to time: New region?

There is also a descriptive page here: Regions

It's the same group running the project as before, part of Oxford University. Some of the models are now supplied by other research groups around the world.

The range of applications has increased, including weather@home. At the moment models are available for Windows and Linux.

The big change in the time I've been running models is the change from global models to regional models, which took advantage of the increased power of PCs. One of the uses of these models now is for "attribution" studies, in which the probability of a real event (a flood, a drought, a fire) is calculated: that is quite a change from the older models, which were principally concerned with predicting climate change and assessing the uncertainties in those predictions.

8000 Windows tasks have been released in batch 864. (PNW region)


and another 4975 batch 865



Science!!

Batch 865 seems to have maxed out at 10,400.

We've been discussing deadlines numerous times, I wonder can't we finally get WUs with 2-3 months deadline top? This will accommodate older hardware and will clean up the queue significantly/

... it used to be the case that the argument was: "if CPDN reduces deadlines then CPDN grabs all CPUs at the expense of other projects, which is not being a good BOINC citizen".

The Linux machines don’t seem to have made contact under that account. It might be worth detaching and reattaching those machines to the project as some of the URLs changed a while ago. Other than that, it would be a good idea to check out the Linux threads in the Number Crunching section of the message board if you haven’t already done that: I’m afraid my Linux machine failed a while ago and I haven’t got around to setting up a new one — the new generation of Linux models seems to have provoked a lot of discussion in addition to the usual 32/64-bit library issues — they’re big models.

There aren’t any Windows models available at the moment — apart from resends — but the last batch was only four days ago so you shouldn’t have to wait long.
