It's not related to the processor splitting (33% per three projects) but to the projects themselves. How can I make Boinc finish a specific work unit (no matter how big or small it is) instead of working on a aunt for 20-30 minutes and then moving onto another one. Especially when one of the work unit's deadline is within the next day or two while the one's it's usually finishing are days/weeks out?

Kind of confusing but I think I described it accurately, is this just how Boinc works?

It's how BOINC works. If you don't like it, you can set the "switch between applications" value to something high, a little more than the run time of that project's tasks if you want. So if they run for 24 hours, set the switch value to 87000 seconds.

It's not going to change, there's not going to be any option ever to continue a task till end, when it's at its last 95% or so, as not all work runs equally and logical.

There is work out there that runs quickly, within minutes, from zero to 90-95% and then runs for hours on the remaining 5%. (Usually the protein folding projects, using Autodock).

There's also work out there that runs for more than 100%. Einstein has a couple of applications that run multiple minutes for 100%, can even be paused at 100% when switching for another project's app. Enigma's application will run to 100%, reset its progress and do it again to 100%.

Climate Prediction still has models where the last 2-10% can take days, if not weeks on even a fast CPU. You do not want this one to take over as then your other work will time out.

Ok, but what you're talking about is between applications, what I was trying to convey was about the same application's different work units. Why it wouldn't just finish the WU it was on instead of transferring the work load to 5-6 different WU's that end up at varying points of completion but eventually never finish up because the time runs out without them being completed.

Everything else concerning how long different projects WU's can take I totally understand.

When I say applications, I meant projects. Sorry!

If you need to quickly finish something in Boinc just suspend everything else. This works for tasks as well as projects. In Boinc advanced view, click on a task (or project) and click suspend. Do this for everything except your "HIGH PRIORITY" task (or project).
