Disadvantages Of Serial Processing Operating System

These interacting processors operate as independent nodes, using their own memory subsystems. Instead, it can be composed of shared memory, used by processors on the same board, or even over a backplane. This communication channel might not necessarily consist of a conventional serial or parallel arrangement. Scalable system architecture allows network administrators to tune a server network’s performance based on the number of processing nodes required.Ĭollections of processors arranged in a loosely coupled configuration and interacting with each other over a communication channel have been the most common multiprocessor architecture. As described in Chapter 2, 'Server Availability,' this feature is known as scalability, and is the most important aspect of multiprocessing system architectures. This permits tuning of the server network’s performance, to yield the required functionality. Today, motherboards are available incorporating multiple microprocessors on the same die.Ī multiprocessing system uses more than one processor to process any given workload, increasing the performance of a system’s application environment beyond that of a single processor’s capability. Not too long ago, clients or network administrators constructed most multiprocessing configurations at the board or system level themselves. With the growth of commercial networks, the practice of using multiple processors in embedded motherboard designs has become almost universal. The main reason why multiprocessing is more complicated than single-processing is that their operating systems are responsible for allocating resources to competing processes in a controlled environment.

However, OS/2 never really caught on for PCs. It is a powerful system, employs a nice graphical interface, and can also run programs written for DOS and Windows. OS/2 has been a standard operating system for businesses running complex computer programs from IBM. For many years, OS/2 has been the choice for high-end workstations. These operating systems include Windows NT, 2000, XP, and Unix.Īlthough Unix is one of the most widely used multiprocessing systems, there are others. A multiprocessing operating system is capable of running many programs simultaneously, and most modern network operating systems (NOSs) support multiprocessing.
