Abstract: A request is received from a first node over a communication fabric, the request to acquire an access right of a cache line for accessing data stored in a memory location of a memory, the first node being one of a plurality of nodes sharing the memory. In response to the request, a second node is determined based on the cache line that has cached a copy of the data of the cache line in its local memory. A first message is transmitted to the second node over the communication fabric requesting the second node to invalidate the cache line. In response to a response received from the second node indicating that the cache line has been invalidated, a second message is transmitted to the first node over the communication fabric to grant the access right of the cache line to the first node.
