CS267: Lecture 4

Shared Memory Multiprocessors

September 10, 2001

Lecturer: Kathy Yelick

Abstract

We start with a short history of parallel machines and the introduction of key features, such as the cache. We describe shared memory machines in some detail, including a basic overview cache coherence protocols. We look at bus-based architectures, distributed shared memory machines, and global address space machines. We look at some specific shared memory machines that represent each of these classes, including the Origin 2000 and the Cray t3e.
