I've set my preferences up so that each work project gets 60 minutes of time. But when I look at the message log Seti has 2 hours of computing time whilst climate prediction only gets 1 hour. Is this becuase Seti has 1 task running and another ready to run, whereas climate only has one task (of 862 hours mind you!)

It should even out eventually. The setting does not give a project that much time, it means that the BOINC client will refigure which project to work on that often. At times the client will decide to work on the same project again.

The 60 minutes at a time setting tells BOINC manager how often to check progress against the scheduler, looking at Short Term Debt. That's set under General Preferences. Another setting that will affect this is the Resource Share, which is set under SETI@Home (or CPDN, or whatever project) preferences. Those are relative numbers that you can use to tell BOINC to give whatever ratio you prefer of your CPU time to the various projects. You can see these numbers, and the %ages they fall out to, on the Projects tab, Resources Share column. Depending on how the work is downloaded, sometimes it will decide that one project needs to catch up on its share of CPU time, and let it run another hour. That's perfectly normal, and part of the time balancing the BOINC scheduler does.

For more information, you can search on any of the key words I just used in the Wiki, see the link on my signature. Or, ask away. Information on the Resource Shares from the Projets tab, or any errors from the Messages tab, could help us explain what's going on to you.

Thanks for the quick answers. Hmmm... I think I understand...
