I suggest some future version have the ability to limit the number of cores a single task can use at once. When Milkyway@home puts out tasks that use all 8 of my CPUs, they prevent other tasks from running. A couple of days ago, they release a number of such tasks at once and everything else was left out in the cold. I don't blame MW for wanting to get their work done, but those of use running multiple projects might like more flexibility.
Thanks, Kirk

Complain at Milkyway for not having an option in their project preferences with which you can choose not to run their N-Body application which does multi-threading. Multi-threading applications will use all cores on a CPU, when you tell BOINC to use one less, the work will stop until either all cores are available again, or the work times out after deadline.

But really, these N-Body tasks don't take up all that long. On my i3 (2+2HT) they ran for all of 8 minutes. Your i5 or i7 should run them in less.
