Claim of US Patent No. 10,042,804

1. A method for processing memory transactions in a cluster having a plurality of processing nodes and an interconnection controller coupled to the plurality of processing nodes, the interconnection controller including a plurality of protocol engines, each engine configured to process multiple memory transactions wherein each of said plurality of protocol engines is configured to be assigned a disjoint subset of a global memory space, the method comprising:receiving a first memory transaction with the interconnection controller;
identifying one of the disjoint subsets using destination information associated with the first memory transaction, the one of the identified subsets corresponding to one of remote and local memory;
selecting a first protocol engine of the plurality corresponding to the identified disjoint subset;
processing the memory transaction with the first selected protocol engine in accordance with a cache coherence protocol;
receiving a second memory transaction with the interconnection controller;
identifying another of the disjoint subsets using destination information associated with the second memory transaction, the other of the identified subsets corresponding to one of remote and local memory;
selecting a second protocol engine of the plurality corresponding to the other of the identified disjoint subsets; and
processing the second memory transaction with the second selected protocol engine in accordance with the cache coherence protocol.
