Just a suggestion: your home page has a list of "Completed Simulations" like "hadAM3P ..." and your Experiments page has things like "Thermohaline experiment"; but, I can't find how to tie the two together. What experiment am I running?

Doing a great job, guys!

You're running 2 types:
The PNW variety are one of three "regional model" types, which consist of a lowish resolution global model, with a higher resolution model inserted in an area of interest to a group of researchers.

The 3 are:
PNW which covers an area in the NW corner of the USA, and is for people based at the University of Oregon.
SA which covers an area at the southern end of Africa, and is for people at one of the Uni's there.
EU which covers Europe, and is for people in either France or Germany, forget which.

These areas can be seen on maps on your climateprediction.net preferences page. Which is also where you choose which of the model types you wish to crunch.

*****************

The other type that you're running is a Coupled Ocean model, which is part of the RAPID-RAPIT Experiment.
This also has a section in our alternative PHP board, here.

Finally, for completion, I'll say it once again: These models are all from the UK's Met Office, who use them for weather and climate forecasting and research.
(The had at the start of each model, stands for Hadley Centre, which is the Met Office's supercomputer complex in Cornwall.

Comments have now been added to the weatherathome and RAPID-RAPIT pages identifying the model prefix for those experiments. That may help other volunteers.

Thanks for pointing this out.

Thanks Les and Iain,

So, I gather from your hints that "hadcm3n..." denotes the Coupled Ocean Model in the Hadley Center's suite of simulations for the RAPID-RAPIT experiment. I also see that "hadam3p_pnw..." denotes the Seasonal Attribution Model with a higher resolution grid for the Pacific Northwest.

I was still a little confused because a site search of "hadam3p" gave as the first result the statement that HadAM3p had retired in mid-2010.

To avoid this confusion for new volunteers, why not simply present the list on the experiments page something like this?:

Thermohaline Experiment
(model ?????)

Seasonal Attribution Experiment
(model "HadAM3P...")

RAPID-RAPIT Experiment
(models "HadCM3N", ...)

By the way, I notice that "HadCM3N" is missing from the list of Complete Model Simulations in the Experimental Status panel. Does this mean that no simulations have yet been competed?

Model types are constantly coming and going, as per the needs of the researchers.
More new types, as well as resurrected old types, are no doubt being considered for the future.
(e.g. The hadsm3 ("slab" models have been resurrected twice since their initial use at the start of the project back in 2003. Some group somewhere is always thinking up new ways to use the various model types.

There will always be something confusing to someone, so the best thing is to do what you did, and ask.

Have you subscribed to the News and Announcements thread at the top of the Number crunching section? That's where things like this get announced.

Missing hadcm3 models: Lots have been completed. There have been several threads in the Number crunching section about them since they started.
I'll ask for the list to be updated.

And just to clarify:
"hadcm3n..." denotes the Coupled Ocean Model in the Hadley Center's suite of simulations for the RAPID-RAPIT experiment.

Not quite correct. That model type has been used for other sub-projects; the RAPID-RAPIT sub-project is just the latest use.

Thanks Les, that clears up a good bit of my confusion. I had been laboring under the misconception that the models were developed specifically for each experiment; I now understand that the researchers designing each experiment generally pick an off-the-shelf model that best fits their needs (I guess the model developers and the experimenters are generally from different organizations or groups).

I should probably post this under the section for new feature requests, but I still think there might be an easy fix that most users would appreciate: the "Show graphics" button in the Task tab is very nice - could you add two more buttons, one linking to the model page (describing the model) and another to the experiment page (the particular experiment using the model)?

The "Show graphics" button is there because that graphics info only exists on your computer, and only while the model is being created. The button activates the separate graphics program, to display the info in next-to-real time.

There's also a button that takes you to your Account page, from where you can get to lots of other info pages about your computer(s), your preferences, and the tasks that you have run and are currently running.
If you're attached to more than one project, you'll need to select the cpdn project first to get the cpdn buttons. Each project has it's own set of buttons.

Information about what experiments are available is posted in the two News and Announcements threads whenever a new batch is released.
If you subscribe to either or both of these threads, you'll get an email each time there's a new post.

The download&upload server status are running
My network%software are normally.
Why I can't download new WU(from 10th-14th June)?
Is there anyone can help me?

Because there is no work to download. If you look at the server status page 5th up from the bottom on the right it tells you how many of each type of work unit are available to download. This happens periodically with this project. With a bit of luck there will be more work soon.
