Using pthread_barrier on Mac OS X While trying to write a threaded application for a course in Parallel Programming, I discovered that pthread barriers are not implemented in OS X, which is supposedly POSIX compliant. So to get my application to compile, I found an implementation of barriers using other pthread features. Apr 03,  · C Server Side Programming Programming Multithreading is a specialized form of multitasking and a multitasking is the feature that allows your computer to run two or more programs concurrently.

If a mutex is in use and another thread tries to acquire it, that thread blocks until the mutex is released by its original holder. A memory barrier acts like a fence, forcing the processor to complete any load and store operations positioned in front of the barrier before it is allowed to perform load and store operations positioned after the barrier.
