Is this possible? How? It's not possible. For most things, you don't want to do that - you want to let the system schedule whichever processor is available next. The S in SMP is for symmetric. If a specific CPU is required to do certain things, the MP is no longer symmetric, it's asymmetric. There are applications where that's desirable, but most don't suffer from being on an SMP system. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
