A large fraction of on-chip multicore interconnect traffic originates not from actual data transfers but from communication between the cores to maintain data coherence. Co-locating directories near their shared data eliminates many interconnect traversals, substantially reducing power and energy consumption. The Web extra at http://youtu.be/MD66DLh9ccU is a video interview in which guest editor Srinivas Devadas and author Nikos Hardavellas expand on how co-locating directories near their shared data eliminates many interconnect traversals, substantially reducing power and energy consumption.
