We will discuss multiprocessors and multicomputers in this chapter. Asymmetric Multiprocessing and Symmetric Multiprocessing are two types of multiprocessing.

How Multiprocessor Are Classified.

. In systems where all CPUs are not equal system resources may be divided in a number of ways including asymmetric multiprocessing ASMP non-uniform memory access NUMA multiprocessing and clustered multiprocessing. Symmetric Multiprocessors Our third model the SMP Symmetric MultiProcessor eliminates this asymmetry. The key objective of using a multiprocessor is to boost the systems execution speed with other objectives being fault tolerance.

Types of multiprocessing systems Symmetrical multiprocessing operating system Asymmetric multiprocessing operating system Symmetrical multiprocessing operating system. In clustered multiprocessing each processor has its own local memory system. When a system call is made the CPU on which the system call was made traps to the kernel and processes the system call.

Multiprocessor System Interconnects Parallel processing needs the use of efficient system interconnects for fast communication among the InputOutput and peripheral devices multiprocessors and shared memory. There are two types of multiprocessors one is called shared memory multiprocessor and another is distributed memory multiprocessor. Depending upon the control structure and its organisation the three basic types of multiprocessor operating system are.

Shared S The addressed line is valid in the cache and in at least one other cache. This helps in simultaneous processing of programs. Asymmetric Multiprocessing system is a multiprocessor computer system where not all of the multiple interconnected central processing units CPUs are treated equally.

Symmetric multiprocessing SMP Asymmetric multiprocessing ASMP Symmetric Vs Asymmetric Multiprocessing Symmetric multiprocessing systems are those that treat all CPUs equally. Multicomputer are a kind of system that are collection of several computers connected together through a network. The line is modified with respect to system memorythat is the modified data in the line has not been written back to memory.

What is the need of the DSP processor. A multicore system would be more efficient if you only need to run one program. There are numerous characteristics of Multiprocessor operating system explain below.

Unlike their general purpose or scientific computing counterparts however most of these processing solutions are highly heterogeneous in nature. 1 Separate supervisor 2 Master-slave 3 Symmetric Supervision Separate Supervisors In separate supervisor system each process behaves independently. The terms multicore and multiprocessor differ in which multicore system refers to a single CPU with several execution units while multiprocessor refers to a system with multiple CPUs.

Heterogeneous multiprocessors also called asymmetric multiprocessors use separate specialized microprocessors for separate tasks and are discussed next. Multi processor system can use different types of processor as per own need such as central processing unit CPU or an input. Operating system of multiprocessing is more complex and sophisticated as it takes care of multiple CPUs at the same time.

Master processor assigns ready state processes to the slave processors. Multiprocessor are classified by the way their memory is organised mainly it is classified into two types which include. There are mainly two types of multiprocessor systems.

Several categories of multiprocessing MP systems exist. Exclusive E The addressed line is in this cache only. Loosely coupled multiprocessor system Tightly coupled multiprocessor system Homogeneous multiprocessor system Heterogeneous multiprocessor system Shared memory multiprocessor system Distributed memory multiprocessor system Uniform memory access UMA system ccNUMA system.

Shared S The addressed line is valid in the cache and in at least one other cache. The SMP model is illustrated in Fig. There is one copy of the operating system in memory but any CPU can run it.

The large majority of multiprocessor systems for embedded computing follow the standard design methodology of programmable CPU cores with associated memories connected via an interconnect framework. When in a single computer two or more than two CPUs are enclosed in such a way that they share the same system buses and other IO devices then it becomes a multiprocessor computer. The line is modified with respect to system memorythat is the modified data in the line has not been written back to memory.

There are many types of multiprocessor systems. A multiprocessor is a computer system with two or more central processing units CPUs with each one sharing the common main memory as well as the peripherals. The data in this line is consistent with system memory.

However a multiprocessor machine would be faster if you have numerous apps running. This type of muliprocessing is also called a pure cluster. Applications of Multiprocessor.

There are five types of microprocessors they are DSP Digital Signal Processor ASIC Application Specific Integrated Circuit RISC Reduced Instruction Set Computing CISC Complex Instruction Set Computing and Super Scalar Processor. The comparison between the two styles of architecture is given below. In shared memory multiprocessors all the CPUs shares the common memory but in a distributed memory multiprocessor every CPU has its own private memory.

Centralized shared memory architectures Uniform memory access time UMA processors Symmetric processors Symmetric Shared Memory multiprocessors SMPs Interconnection is traditionally through a bus scalability problem Simpler software model. The data in this line is consistent with system memory. Other forms of multiprocessing include heterogeneous multiprocessing and clusters.

Multiprocessor Operating System Types of multiprocessor operating system There are two main types of multiprocessor OS 1 Asymmetric multiprocessing system In this type of system one processor behaves as a master and the other processors behave as slaves. The Multi processor system allows making communication in between multiple CPUs with their share memory and inputoutput devices. Shared nothing MP The processors share nothing each has its own memory caches and disks but they are interconnected.

Exclusive E The addressed line is in this cache only. Systems that treat all CPUs equally are called symmetric multiprocessing SMP systems.
