Abstract
The memory overhead introduced by directories consti-
tutes a major hurdle in the scalability of cc-NUMA archi-
tectures, which makes the shared-memory paradigm unfea-
sible for very large-scale systems. This work is focused
on improving the scalability of shared-memory multipro-
cessors by significantly reducing the size of the directory.
We propose multilayer clustering as an effective approach
to reduce the directory-entry width. Detailed evaluation
