Abstract
A computer-implemented method for enforcing cache coherence includes multicasting a cache request for a memory address from a requesting node without an ordering restriction over a network, collecting, by the requesting node, a combined snoop response of the cache request over a unidirectional ring embedded in the network, and enforcing cache coherence for the memory address at the requesting node, according to the combined snoop response.
