Lecture24 Multiprocessor

This document discusses operating system approaches for multiprocessor systems. It compares single-processor OSs, which are easier to support synchronization and scheduling, to multiprocessor OSs. Multiprocessor OS approaches include shared OS, master-slave, and each CPU having its own OS. The document also covers multiprocessor hardware, applications, OS synchronization using techniques like test-and-set locks, and scheduling considerations for multiprocessor systems like timesharing and cache affinity.
