Install BOINC on your computer
Run BOINC on your computer
You will be asked to enter the project's URL, which is climateprediction.net.
The BOINC client should then connect to our server.
You can then create your account, or enter your current account details
The server should send you your first climate model experiment.
Watch your model using the visualisation
- Please read the following before participating in the experiment:
- Download BOINC for your type of computer
If you do not get a workunit, please check the project URL entered, check that your system settings
(i.e. diskspace, memory, computer speed etc.) fulfil our technical
requirements, and make sure your user/machine preferences on the BOINC website are properly set.
When you run BOINC on your PC, it works as follows (see below):
- Your PC gets a list of instructions from the project's scheduling server.
The instructions depend on your PC: for example,
the server won't give your PC work that requires more RAM than you have.
The instructions may include many separate pieces of work.
Projects can support several "applications",
and the server may send you work from any of them.
You can find out which applications climateprediction.net is currently
running, here. The application is a combination of
which particular experiment
is currently running and any technical upgrades that have been made to the software.
- Your PC downloads executable and input files from the climateprediction.net data server.
If climateprediction.net releases new versions of its applications,
the executable files will be automatically downloaded to your PC.
- Your PC runs the application programs, producing output data.
- Your PC uploads a selection of these output files to the data server.
- Your PC reports the completed results to the scheduling server,
and gets instructions for more work.
This cycle is repeated indefinitely until you choose to change to a different BOINC project or to
uninstall BOINC entirely.
BOINC does this all automatically; you don't have to do anything.
Credits are computed differently by climateprediction.net than by other BOINC projects, although we
still use "Cobblestones" as our unit of credit. "Cobblestones" can be compared with work
done on other BOINC projects. One climateprediction.net workunit is one complete
Therefore, since climateprediction.net workunits take a long time to complete,
"incremental credit" is granted with each trickle to the scheduling server. This occurs
every 10802 timesteps, and gives about 75 cobblestones of credit for experiment 1
(.00875 cobblestones per timestep). This should equate to a similar amount of SETI@Home work.
Periodically we may update the "cobblestone equivalency" to reflect the changing experiments
etc. This should allow direct comparison between work done on different BOINC projects.
Watching your Modelled World
There are various visualisation packages which will allow you to
watch the development of the weather on your version of the Earth.
If you are running Windows, you can open the standard BOINC graphical program by double-clicking
on the "B" icon in the taskbar at the bottom-right of your screen. To open the visualisation, you
simply right-click on a running model in the "Work" tab, and choose "Show Graphics."
This will bring up a visualisation window of the selected model.
Note that if you are running a
dual-CPU or hyperthreaded system, you may have one or more other models to select and view.
Also in Windows, you can use the "boinc.scr" Screensaver (which should be installed
in your \windows\system32 directory) to show your BOINC project as a screensaver.
Since screensavers take a bit of CPU time from the calculation, you may wish to go
to "Display" and set the screensaver to go to a blank screen after a few minutes.
