Author | Topic: TeamEvC: Climate Prediction. | |||||||||||||||||||||||
ohnhai Member (Idle past 5162 days) Posts: 649 From: Melbourne, Australia Joined: |
I noticed a link in Kuseru's Sig
ClimatePrediction Basically it's a Distributed computing experiment set up by the BBC to explore the robustness of the Model used by the UK Met office for long range climate predictions. Anyway if you have a reasonably quick machine and sit for many hours with it idling away while you read EvC or watching DVDs then you might want to consider donating a few free cycles to this project. Curently there are three of us in the team (Was started by Chris) Note read the FAQs especially in regard to machine sepcs, how long it will take, how long you normally have your machine on for and quitting early . .. Before connecting to the project. TeamEvC. join up at Climate Modelling to help improve climate predictions.

thanks for joining the team
beat me to creating this thread, but who cares. oh, by the way. . .kuresu = chris one warning to all--these projects take a while, unlike the TeamEvC on the world community grid--going up against HIV/AIDS. if I understand it correctly, everyone on the team works on the same project--in this case climate prediction. the one currently running on my computer is running through the weather of the 20th century. After running all night, it made it from february 1921 to october 1921. Also, if anyone has any ideas as to how to make this more effiecient, let me know. Being the founder, anyone who joins the team (and please do) uses my preferences for the project. So . . . anywhoplease join up people (especially you lurkers--all 130 of you) abe:another cool feature of this project--you can actually see the model running, and switch between temp, pressure, cloud and rain. (at least, you all should be able to, depending on how you get it setup) you can't do that with the HIV/AIDS project. Edited by kuresu, : No reason given.

It looks very interesting. I'm having trouble getting the model to work, however. This is probably due to my OS though - will keep investigating.
After running all night, it made it from february 1921 to october 1921. Where does it show the timeline?

the model can be shown if you pick the shared or single install for when the program runs.
to access the model, click on the "tasks" tab. then hit "show graphic". timeline is up at the top of that screen. hope that helps mine just hit 1922. one correction--the project I'm working on goes from 1920-2080. just checked the member's list--we've a total of five people.

Still can't view the graphics, maybe an xorg problem... If any other linux users get it working can you please let me know how you did it?
Or maybe I'm missing something obvious...

note sure. are you running it as an alpication or a service? I think I reas somewhere the graphics are not available if you run it as a service (could be just a windows thing)

one warning to all--these projects take a while, Yup. for a quick machine the runtime could well be 3-4 months this is because for each processor you tell it to use they assign a whole model run (splitting a highly complex model like this across mutliple machines would cause way too much net trafic.) As my machine is dual core I am currently running two models. getting 2.20 s/TS for the first and around 4 s/TS for the second.

Had to drop out. Sorry. The sucker took over the BOINC app and had two of them suckers running with two more waiting. It was taking all the time from the Grid project.

Yes, unless it's possible to run alongside the grid, i will also have to stick with the HIV project.

ok okay I guess I will put it on my work computer tomorrow and keep the HIV thing running on my laptop.

I've actually got the grid (HIV) and the boinc(climate) running at the same time. granted, I've set it so that the grid only consumes 60% of my processing power. I haven't had any problems yet.
Oh, Jar.This morning I found that I had two climate models, one running. THe only reason I can think this happened is that I had to suspend the model (my game was do some serious freezing up last night--damn graphics card). When I turned on my computer, it had automatically loaded a new climate model and was starting to run it. I aborted that one and got back to my original one. Maybe something similar happened to yours? thanks for joining, mick Want to help give back to the world community? Did you know that your computer can help?

okay--that program just loves to screw with you. If you suspend any model that's running, it will pretty much find a new one when you turn your computer on. When I aborted the new one, it started on a next one. It keeps on unless you have one running. Once I put the original model back on run, it stopped it's download spree. (so long as you have an instantaneous internet connection, like I've got where I'm currently at).
anyone have a clue why it automatically does this, and is there a way to turn that off? Want to help give back to the world community? Did you know that your computer can help? Join the newest TeamEvC Climate Modelling to help improve climate predictions for a better tomorrow.

I would guess that it has to be that way.
If you stop the computation on one model, then the distributed processing is going to move that computation to somebody else's computer. And when you restart, it is going to feed you the next thing that needs to be computed.
