SuperSPARC-Based Multiprocessor Hardware

Several classes of multiprocessor machines are based on SPARC architecture: 1- to 4-processor, MBus-based systems; high-end systems with up to 8, 20, or 64 SuperSPARC processors; 1- to 4-processor UltraSPARC-based systems; and high-end UltraSPARC servers with up to 30 and up to 64 processors. Their system architectures are quite different and all are quite complex. I’ll start by discussing bus architectures in general, then look at the implementations of systems based on SuperSPARC. Then, I’ll describe the bus architectures and implementations used by UltraSPARC.
