Modeling cache coherence protocol overhead

Participants : Bertrand Putigny, Denis Barthou, Brice Goglin.

• We are building a fine grained cache model to understand common cache coherence issue.

• This model is built on a set of micro-benchmarks and can also be used to improve find some bottlenecks in memory bound code. Our set of micro-benchmarks can also be used as a test bed for new architectures [54] .
