ABSTRACT
Token coherence provides a flexible framework for designing
new coherence protocols which decouples performance from
correctness, easing the design of efficient coherence proto-
cols. In this work, we have implemented a coherence pro-
tocol for a cc-NUMA architecture based on TokenB using
the RSIM performance simulator to validate previous claims
about token coherence performance and viability. Unlike
previous works, we have used scientific workloads to evaluate
