ABSTRACT:
A flat directory organization is used to create a flat cache-only multi-processor architecture. Directory memories are uniformly distributed among all the processor nodes. Every valid memory partition has an associated physical address, which is used to determine a statically assigned home node for that partition. The home directory at the home node is the only directory that maintains state information for that partition. The home directory keeps track of which nodes have a copy of a partition and the current state of that partition. The flat directory organization does not depend on any specific interconnection. Any scalable network can be used to interconnect the processing nodes.
