I currently have, on 1 machine, close to 200 tasks. All of them, bar one, have a deadline in August. The odd man out is an AP i got in early June, it has a deadline of July 2nd. Does deadline date have no bearing on when a task is processed? I ask coz Boinc is crunching everything except the AP, and it puzzles me ;-)

BOINC generally does a first-in first-out processing.

IF BOINC thinks your AP task is in danger of hitting it's deadline it will put priority on that task.

Or, you can suspend the other tasks and let AP start if you are worried about it.

The deadline date will be used when tasks are running "High Priority". Which happens when BOINC doesn't think they will be completed in time otherwise. However by the rules of FIFO & High Priority that tasks should be worked on before all of the new work you are completing & returning. Unless you have work from another project which is taking precedence, but it doesn't look that way from what I can see. If you had that task suspending then BOINC should be refusing to get new work. With a message along the lines of "Not fetching work, some tasks are suspended".

You can try forcing BOINC to run in High Priority mode, if it is not already, by increasing the value for "Store at least --- days of work". Setting it from 10 to 12 should give BOINC a kick in the pants & force it to run that AP task if you like.

Thanks for the explanation, I'll leave Boinc to do its own thing...;-)
