What does it mean? -<P> -What it means is that you can use the ACE_Barrier to cause a set of -threads to all wait at a specific point in your application. In other -words: the threads reach a barrier that none can pass until all are -present. -<P> -This would typically be used in scientific applications where a set of -threads are all working in parallel on some great computation but they -have to synch and summarize before continuing to the next stage of calculation. With -proper use of ACE_Barrier, the threads can easily synch before -continuing. -<P> -In this tutorial I'll create a simple wrapper for the ACE_Barrier. In -reality, the ACE_Barrier is so easy that a wrapper isn't really -needed. I created the wrapper anyway though just because I wanted to. -<P> -Kirthika's abstract: -<ul> -The ACE_Barrier class is used for collective thread syncronisation. All -the threads block at the barrier and advance only after everyone is at -the -barrier. A thread blocks by calling the wait() method and stays until -all the other threads invoke wait() one-by-one at the barrier and then -all -move ahead. -Here, an abstract barrier class is created which incorporates the -ACE_Barrier -mechanism and is used in a test case of an ACE_Task with 10 and 5 -threads respectively -which illustrate the use of the barrier pattern. -</ul> -<P><HR WIDTH="100%"> -<CENTER>[<A HREF="../online-tutorials.html">Tutorial Index</A>] [<A HREF="page02.html">Continue This Tutorial</A>]</CENTER> - |
