Threads in a Process. Threads are useful at user-level. Parallelism, hide I/O latency, interactivity. Option A (early Java): user-level library, within a single-threaded process. Library does thread context switch. Readings. . Silberschatz. et al : Chapter 4. Motivation. Sometimes a program needs to do multiple tasks concurrently. Example: Word processor . Tasks include: Display graphics, respond to keystrokes from the user, and perform spelling and grammar checking. Written by Amir Kirsh, Dr. Yaron Kanza. Edited by Liron Blecher. Agenda.
