A new network interface optimized for SARC supports synchronization and explicit communication and provides a robust mechanism for event responses. Full-system simulation of the authors' design achieved a 10- to 40-percent speed increase over traditional cache architectures on 64 cores, a two- to four-fold decrease in on-chip network traffic, and a three- to five-fold decrease in lock and barrier latency.
