While trying to switch out comps to assign certain projects to certain comps, I realized that no project get new tasks. Does the completion time on the CPN preclude other tasks from downloading until its crunched down a bit?

It depends upon the settings in Your Account.

Well each product is evenly meeted out CPU time. I have requested up to 10 days of work from Rosetta. Down to the last 5 2.5 hr tasks and still getting no new work. I am runnin a Couple model with a ridiculous completion time and CPN downloaded a DAM3 before I could hit \'no new tasks\'....9-).

Question is... with the high completion time is Rosie thinking I can\'t handle anymore work even though the completion date is some 3 years from now?

Ooops forgot, I don\'t think its an issue of space since projects are limited to 57GB of space on this harddrive unless of course it has anything to do with the memory required by the HDAM3 though there is 3GB of memory installed.

It\'s not \'Rosie\', it\'s your BOINC. It\'s got more work than it can handle, and won\'t allow anything else to download.

It will stay like that for days, or even weeks, and then, when it\'s worked out a \'work schedule\' to include both climate models and other projects, it\'ll suddenly realise that things aren\'t as bad as it first thought, and allow work from other projects.

This is normal for computers running other projects that suddenly find a climate model added to the mix.

It also seems that you haven\'t altered your preference settings in your climate project account to select the type of model that\'s sent to you.
If you do this, you can get shorter models, so that other projects don\'t suffer.

And if you start turning the climate models on and off so as to allow work from other projects, you\'ll just prolong the time that it takes BOINC to create its \'work schedule\'.

PS
Don\'t get lulled into thinking that the climate models aren\'t needed for 3 years.
That\'s just to fool BOINC into not panicing. The models are required ASAP. Leave some of them too long, and the research for that model type may well be over and done with before you finish the model.

Actually I HAVE modified my preferences getting after the downlods from 4 to a 10 day buffer. Actually never expected to get two climate models with a project already running and a four day buffer. Had no intention of monkeying with the comp to \'prolong or shorten any runtime. It was just a question. You answered it in your first few sentences.

The preference you see on my comp page is an experiment as I was having trouble running the HADAM3 on the AMD so I deselected all. My orignal preference was for those type models ONLY.

You\'re the only one who can see your preferences.
I inferred that you hadn\'t specified a model type by your saying that you had a TCM and then received a hadam model.
