Line 8:
An advantage of a multi-threaded program is that it can operate faster on machines that have multiple CPUs, or across a cluster of machines. This is because the threaded nature of the algorithms allow true simultaneous and
independent processing. In such a case, the programmer needs to be careful to avoid [[race condition]]s, and other non-intuitive behaviors. In order for data to be correctly manipulated, threads will often need to [[rendezvous]] in time in order to process the data in the correct order. Threads may also require an [[atomic]] operation known as a [[semaphore]] in order to prevent data from being simultaneously modified, or read while in the process of being modified. Careless
