Computer Memory Hardware

A comprehensive introduction to reliability and availability modeling, analysis, and design at the system, hardware, and software levels Reliability of Computer Systems and Networks presents the fundamentals of reliability and availability analysis for various computer hardware, software, and networked systems. Reliability and availability as major objectives in system design are the focus. Various redundancy and fault-tolerant techniques, as well as error-correcting coding techniques are treated. The author proposes a high-level design approach based on apportioning the reliability and availability goals to subsystems and provides various techniques for achieving these subsystem goals. The next step is an efficient, exact optimization approach based on upper and lower bounds to minimize the number of feasible candidates. The most readily applied methods for analysis are utilized and design techniques are derived from basic principles. Analytical simplifications and approximations are developed to validate the results of computer models used for large-scale complex problems. Coverage includes: Coding and decoding schemes for error detection and correction including chip reliabilityComparison of the reliability and availability of parallel, standby, and majority voting architecturesFormulation, solution, and interpretation of Markov models for repairable systemsIntroduction and comparison of various RAID memory systemsThe architecture and fault-tolerant principles of TANDEM and STRATUS non-stop computer systemsPractical and tutorial examples and numerous practice problemsAppendices which cover the necessary background material on probability, reliability, andarchitecture Reliability of Computer Systems and Networks offers in-depth and up-to-date coverage of reliability and availability for students with a focus on important applications areas, computer systems, and networks.

In addition to thoroughly updating every aspect of the text to reflect the most current computing technology, the third edition *Uses standard 32-bit MIPS 32 as the primary teaching ISA. *Presents the assembler-to-HLL translations in both C and Java. *Highlights the latest developments in architecture in Real Stuff sections: + Intel IA-32 + Power PC 604 + Google's PC cluster + Pentium P4 + SPEC CPU2000 benchmark suite for processors + SPEC Web99 benchmark for web servers + EEMBC benchmark for embedded systems + AMD Opteron memory hierarchy + AMD vs. 1A-64 New support for distinct course goals Many of the adopters who have used our book throughout its two editions are refining their courses with a greater hardware or software focus.

Shared memory - In computer hardware, shared memory refers to a (typically) large block of random access memory that can be accessed by several different central processing units (CPUs) in a multiple-processor computer system. The issue with shared memory systems is that the many CPUs need fast access to memory and will likely cache memory.

Direct memory access - Direct memory access (DMA) allows certain hardware subsystems within a computer to access system memory for reading and/or writing independently of the CPU. Many hardware systems use DMA including disk drive controllers, graphics cards, network cards, and sound cards.

Distributed shared memory - Distributed Shared Memory (DSM), in computer science, refers to a wide class of software and hardware implementations, in which each node of a cluster has access to a large shared memory in addition to each node's limited non-shared private memory.

Physical memory - The memory hardware (normally RAM) installed in a computer. The term is only used in contrast to logical memory.
