An important type of synchronization in a multiprocessor is a barrier synchronization. The idea of the barrier synchronization is that prior to the barrier, all processes run in parallel and asynchronously. However, no process can pass the barrier until all have reached it. Barriers of this form are well known in the literature [1].
