Right now you can get the threads that are active and do a thread->setProcessorAffinity(cpunum) but some OS's require you to assign the affinity at setup rather than once it's running so it won't be an option for all. It's been my plan to revise the way that thread affinity is set up with the OSG to allow user customization of thread affinity, this would either have to be done by setting up the GraphicsContext::Traits and to give hints the DatabasePager prior to the threads starting, or to have a callback that provides the hints of what affinity to set for each new thread being created. The threads would need to identify themselves in some way for this callback to know what to do with them - perhaps both a class of thread and other details. I'm open to suggestions on how this new support might be implemented.
