Scalability is a key concern for SMP based architecture in the current context. NUMA based architecture design seems to be a promising hope addressing this key concern. At the same time CC-NUMA based design architecture demands a deeper understanding and open vistas for key areas of improvement. Our proposed research tries to investigate, evolve and analyze one of the key design issues for NUMA machine and proposes an innovative solution to address this key design issue under investigation in the current phase of our work.
