Features: This book systematically studies the key issues in the architecture of shared memory systems. The main contents include: establishing an execution correctness model for shared memory systems, defining the concept of execution in shared memory systems, and identifying that the key factor determining an execution result is the execution order of conflicting accesses in this execution; based on the correctness of a typical implementation of sequential consistency, deriving a scheme for out-of-order execution; establishing an address-stream-driven simulation model to evaluate the impact of different memory access event sequences on performance; proposing a new cache coherence protocol based on locks for implementing a domain consistency model, and comparing software distributed shared memory systems (DSM) and message-passing parallel environments in terms of programmability and performance; pointing out that utilizing software to implement shared memory while providing necessary hardware support is a method that can both improve system programmability and effectively enhance performance. This book can be used as a graduate textbook and also provides reference value for related technical personnel.
