Synchronization mechanisms

Synchronization of tasks is the coordination between those tasks to get the desired results. In concurrent applications, we can have two kinds of synchronizations:

  • Process synchronization: We use this kind of synchronization when we want to control the order of execution of the tasks. For example, a task must wait for the finalization of other tasks before it starts its execution.
  • Data synchronization: We use this kind of synchronization when two or more tasks access the same memory object. In this case, you have to protect the access in the write operations to that object. If you don't do this, you can have a data race condition where the final results of a program vary from one execution to another.
