PPT-Threads and Critical Sections

Thomas Plagemann Slides from Otto J Anshus Tore Larsen University of Tromsø Kai Li Princeton University Overview Intro to threads Concurrency Race conditions amp critical regions. 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. Dan C. Marinescu. Office: HEC 304. Office hours: M-. Wd. 11:30 - 12:30 . A. M.

Posix Threads (Pthreads) Concurrency Chapter 26 Abstraction: Threads Here we introduce a new abstraction for a single running process: that of a thread. The state of a single thread is thus very similar to that of a process. It has a program counter (PC) that tracks where the program is fetching instructions from Want to know the advantages and disadvantages of critical illness cover?
