Why? MIME-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Content-Disposition: inline Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org I have a four processor box, running three compute loads. The kernel I'm running is 2.6.25-gentoo-r5. One process has four threads, and it's niced to 19. Another process has one thread and is niced to -10 The last process has one thread and is niced to 0 One processor is always idle. If I change either the 0 to a -10 or the -10 to a zero, then all four cores are properly utilized. Does this make sense to anyone? Besides messing with the nice levels, is there another way to fix this? Thanks! -- Timothy Normand Miller http://www.cse.ohio-state.edu/~millerti Open Graphics Project
