    Neural network machine architectures based on knowledge about biological computers such as the human brain are discussed. The limitations of the Von Neumann machine for doing many tasks are noted, and a simple neural network is described. The two basic types of memory supported by neural network machines, autoassociative and associative, are discussed. A mathematical description of an autoassociat... View full abstract»

    Two common dependability measures of fault-tolerant systems, availability and reliability, are defined, and the design of a reliable system is described. The first step is the incoming inspection of components to remove weak or defective components prior to assembly into subsystems. The next step is to use fault-avoidance techniques. Examples are careful signal routing, shielding, cabinet groundin... View full abstract»

    A system called netlib that provides quick, easy, and efficient distribution of public-domain software to the scientific computing community on an as-needed basis is described. A user simply sends a request by electronic mail on a national network such as ARPAnet and receives the requested software over the network. The public-domain software currently included in netlib is listed.<> View full abstract»

    The author examines the evolution of digital computers and the question of whether modern computers are any different in principle and basic architecture from the computers of several decades ago. He describes the basic Von Neumann style, serial computer architecture. He discusses two ways to speed up the performance: overlapping of instruction fetch, decode, and execution, called the principle of... View full abstract»
