Thread Programming Models

The execution of a multithreaded program follows a "fork-join" fashion. Threads are created on demand, work on their own tasks and then join at the end.

A process starts as a single thread. After it forks off indivdual threads, it becomes the main thread. The main thread must stay alive during the execution.

Multithreaded programming naturally requires the thinking of programming models, i.e. one must consider issues like which thread does what at the same, etc.
