Hi Jonathan, I am currently looking into different affinity policies on the Niagara architecture, including the application threads and interrupt handlers. An important aspect of this work is the hierarchy of processing units (chips, cores, threads) with respect to cache sharing, resource utilisation, etc. I believe this quite relevant to what you have in mind. I'll be more than willing to co-operate with you, or anyone else in the OpenSolaris community, on this subject.
