The contents of this chapter include all of the following: Overview, multithreading models, threading issues, pthreads, windows XP threads, Linux threads, Java threads. | Software Construction Lecture 17 Threads Overview Multithreading Models Threading Issues Pthreads Windows XP Threads Linux Threads Java Threads Threads Single and Multithreaded Processes THREADS Benefits Responsiveness Resource Sharing Economy Utilization of MP Architectures THREADS User Threads Thread management done by user-level threads library Examples - POSIX Pthreads - Mach C-threads - Solaris threads THREADS Kernel Threads Supported by the Kernel Examples - Windows - Solaris - Tru64 UNIX - BeOS - Linux Scheduling THREADS Multithreading Models Many-to-One One-to-One THREADS How do user and kernel threads map into each other? Many-to-One Many user-level threads mapped to single kernel thread. Used on systems that do not support kernel threads. Examples: Solaris Green Threads GNU Portable Threads THREADS One-to-One Each user-level thread maps to kernel thread. Examples - Windows - Linux THREADS Threading Issues Semantics of fork() and .
