Abstract
A symmetrical multiprocessing system includes a plurality of nodes interconnected by a hierarchical bus. To allow for the transfer of data between nodes and to restrict the global transfer of local transactions, a plurality of address partitions are defined: global space, local space, remote read space, and remote read and write space. Process private and local data is accessed using local space. Global data is accessed using global space. In one embodiment, a kernel of the operating system is resident in the local space of each node. Because the memory space where the kernel resides is designated as local space, no other nodes can write to, or corrupt, the node's kernel.
