Computer architecture deals with the physical configuration, logical structure, formats, protocols, and operational sequences for processing data, controlling the configuration, and controlling the operations over a computer. It also encompasses word lengths, instruction codes, and the interrelationships among the main parts of a computer or group of computers. This two-volume set offers a comprehensive coverage of the field of computer organization and architecture.

machines show superior performance to other machines based on the reported SPECbase, they show inferior performance using the SPECpeak, and vice versa. For the abovementioned observations, it became apparent to a number of computer architects that SPEC92 does not predict faithfully the performance of computers on random software for a typical user. In October 1995, SPEC announced the release of the SPEC95 suite, which replaced the SPEC92 suite fully in September 1996. SPEC95 consists of two

programming model follows the shared memory school of thought. In effect, software covers up the hardware. As far as a programmer is concerned, the architecture looks and behaves like a shared memory machine, but a message passing architecture lives underneath the software. PROBLEMS 1. Explain mutual exclusion and its relation to the cache coherence problem. 2. Discuss the advantages and disadvantages of using the following interconnection networks in the design of a shared memory system. (a)

programming is supported by the help of a dynamic process structure with active process scheduling. The Cosmic Cube is considered the first working hypercube multicomputer message passing system. The Cosmic cube system has been constructed using 64 node for the Intel iPSC. Each node has 128 KB of dynamic RAM that has parity checking for error detection but no correction. In addition, each node has 8 KB of ROM in order to store the initialization and bootstrap programs. The basic packet size is 64

Ethernet. In late 1997, a good choice for a cluster system was sixteen 200 MHz P6 processors connected by Fast Ethernet. The network configuration of a high-performance cluster is dependent on the size of the cluster, the relationship between processor speed and network bandwidth and the current price list for each of the components. 7.4.2 Switches An n1 Â n2 switch consists of n1 input ports, n2 output ports, links connecting each input to every output, control logic to select a specific

connections among inputs and outputs. Depending on the switch settings, different interconnections can be established. Nearly all multiprocessor systems can be distinguished by their interconnection network topology. Therefore, we devote Chapter 2 of this book to study a variety of topologies and how they are used in constructing a multiprocessor system. However, in this section, we give a brief introduction to interconnection networks for shared memory and message passing systems. Shared memory
