My apologies if this has been asked before. What would be considered the lowest specs to be able to run the climate prediction program. I ask because my current system has 4 models running but is often over committed with work and suspends work fetching.
I have my account here already and I am thinking of running up another pc to run the climate program on its own for about 12 hrs a day.
Obviously I would transfer my existing model to the 2nd pc and remove it from the first one. I would need advice on this to do it properly. Any advice would be helpful...
Thanks.
Eric

The minimum is considered to be 1.6 GHz, to enable completion of a model in a reasonable time, but faster is better. And 1Gig of ram; more if you ever want to also run the Seasonal Attribution Project.

If you have that many models running, you\'re probably suspending the work by using the Suspend in the Tasks tab.
All this does is suspend the model, so that BOINC then asks for more work.
Use the Suspend in the menu, which suspends both the model AND BOINC.

Also, go to the projects tab, click on the project name, and then on the \"No new tasks\" button. This will make sure that no more climate models get sent to you accidently.

There is a section on moving a model to a different computer in the README file called: Running the Model.
This is one of 5 README files here.

Backups: Here

Moving the model from one computer to another is hardly different from making a backup of the contents of the boinc folder, then restoring the contents to an empty boinc folder. If you haven\'t been making backups so far, I\'d recommend Les\'s easy and fail-safe manual method for backup and restore, which is the first item in the README about avoiding model crashes.

But you need to get the boinc folder backup onto somewhere that the new computer will be able to \'see\', eg a disk or external drive.

It doesn\'t even matter if you\'re not successful first time because you can have multiple tries. The boinc folder\'s contents on the \'old\' computer will still be a fully-functional package and only need to be deleted/detached or whatever once you have everything up and running on the new computer.

Best to complete your current model first, but when you do need a new model to suit your computer\'s requirements, there\'s a summary of currently available cpdn models here:

Cpdn news

Thankyou for the replies and comments.

I have now transfered my climate program to a different computer where it can run happily up to 12+ hrs a day. What is a safe method of removing it from my existing system? A simple detach? Because its on computer 2 I want to remove it from computer 1 and run smaller projects through computer 1. Computer 2 will be dedicated to climate only. Sorry if this is a daft noobish question.
EDIT: I have just seen that a simple detach will be ok.

Congrats on getting all of that sorted out.

If the computer you\'ve moved the model to is a good deal faster than its old home, I\'d advise you to look at the post on this topic in the README called Running the model. The post is in the section about moving models from one computer to another. Just in case this should cause a problem before the model completes, it would be a good idea to make regular backups of the contents of the boinc folder, at least once a week.

You don\'t need to spend ages studying that long post, but it\'s a good idea to be aware of what the potential problem consists of.

Won\'t detaching from the first PC cause the model to be aborted?

While this doesn\'t actually matter (the servers at Oxford don\'t take any notice of Boinc\'s status), you\'d probably prefer to have it showing as \'running\' or \'successful\' on the website.
