Abstract :
We propose implementing cache coherence protocols within the network, demonstrating how an in-network implementation of the MSI directory-based protocol allows for in-transit optimizations of read and write delay. Our results show 15% and 24% savings on average in memory access latency for SPLASH-2 parallel benchmarks running on a 4times4 and a 16times16 multiprocessor respectively
