Abstract

A plurality of processors, each with caches provided for a plurality of processor modules and a local storage in which a main storage is distributed and arranged are mutually connected through an internal snoop bus. The processor modules are mutually connected through a second system bus. By using two separate buses, cache coherence operations within a processor group is kept separate from cache coherence operations outside the processor group.
