Early to mid 20th century scientific computing was performed by human "computers" sometimes assisted by calculating machines, differential analysers, or punch card tabulating machines. Electronic digital computers became available starting in 1946 with ENIAC and by 1953 at least two dozen major computers had been under construction. The first mass-produced computer with floating point hardware, the IBM 704, was introduced in 1954. The FORTRAN progamming language was created a short time later to produce efficient code with less effort by the programmer. High speed computing systems, some employing concurrent operation, developed rapidly during the next decade with notable examples such as the CDC 6600 and ILLIAC IV. By the late 1960s a diverse variety of these specialized systems for scientific computing became known as supercomputers.

Metaphysics Research Lab, Stanford University. “As computer simulation methods have gained importance in more and more disciplines, the issue of their trustworthiness for generating new knowledge has grown, especially when simulations are expected to be counted as epistemic peers with experiments and traditional analytic theoretical methods. The relevant question is always whether or not the results of a particular computer simulation are accurate enough for their intended purpose.”

Winsberg explores the impact of simulation on such issues as the nature of scientific evidence; the role of values in science; the nature and role of fictions in science; and the relationship between simulation and experiment, theories and data, and theories at different levels of description.

The development of the supercomputer has given scientists an awesome new capability: the power to virtually re-create the physical world on the computer screen, with a stunning degree of precision and sophistication. Everything from weather systems to biochemical interactions to car crashes to air pollution to high speed subatomic particle collisions can now be simulated, and observed at the scientist's will. As a result, suupercomputers have led to profound levels of insight and understanding. Indeed, they have revolutionized the very process of scientific discovery itself. Scientists no longer have to rely exclusively on either experiment-based or theoretical research methodologies, but rather can utilize both direct observation and mathematical modeling to visualize and simulate complex phenomena.

This book describes computers designed and built to solve specific scientific problem, comparing these computers to general purpose computers in both speed and cost. Discussed as wellare the effort involved, the amount of time consumed, and the difficulties encountered in completing such projects. The special purpose computers described include the hypercube, the QCD machine, Navier-Stokes hydrodynamic solvers, classical molecular dynamics machines, and Ising model computers.

Supercomputers - fare more powerful then the largest mainframes - comprise one of the fastest growing segments of the computer industry. Spurred by $200 million in federal funds, new supercomputing centers at American universities are making it possible for much larger numbers of researchers in science and industry to take full advantage of the enormous speed and power of supercomputers and at much lower cost.

Today's conventional computers are characterized by sequential, serial operations proceeding back and forth between a single powerful processor and a separate large-scale memory. The Connection Machine, by contrast, is a general, universal parallel computer, in which thousands or millions of independent, simple processors - each integrated with its own small but sufficient memory - operate concurrently on different aspects or segments of the same overall problem.

The Fifth Generation: a new breed of supercomputers so fast they can surpass today's machines a thousand times over, so smart that they can outthink humans. Science fiction? Not quite. Japan has proclaimed to the world that in ten years it intends to develop and market the Fifth Generation of computers - artificially intelligent machines that can reason, draw conclusions, make judgments, and even understand the written and spoken word. In a crash program, comparable to the U.S. space effort, Japan has gathered the best and brightest under a charismatic leader and backed the enterprise with significant resources.
