POSIX Threads
Explore how POSIX threads enable multithreading in C programming, allowing you to create concurrent threads that run independently but share memory. Understand thread creation, execution, and termination along with the challenges of race conditions and synchronization. This lesson helps you grasp the foundations of parallel programming with pthreads to improve program efficiency and scalability.
We'll cover the following...
Multithreading
The threads model of parallel programming is one in which a single process (a single program) can spawn multiple, concurrent threads (subprograms). Each thread runs independently of the others, although they can all access the same shared memory space (and therefore they can communicate with each other if necessary). Threads can be spawned and killed as required, by the main program.
Once spawned by a program, threads are concurrent units of processing that can then be delegated by the operating system to multiple processing cores. Clearly, the advantage of a multithreaded program (one that uses multiple threads that are assigned to multiple processing cores) is that you can achieve big ...
