1967 Spring Joint Computer Conference, AFIPS 1967

A programmer in writing and checking out an arithmetic computer program provides both a procedural description of the program and a set of numeric test cases. Similarly, a student of elementary physics is often given a set of formulae to be used, and correct answers to problems. These two inputs in both cases provide a redundancy which gives some measure of confidence that the procedure is correct. In theory either is adequate, subject to the limitations of induction. While compilers operate upon the first type of data, several programs have been written which use the second type. © 1967 ACM.

Digital computers have evolved in their own technical environment, and to a large degree independently of the problem environment. Thus it was necessary to have computing centers with staffs of programmers as intermediaries between machines and users. As the inadequacy of the arrangement became apparent, problem-oriented languages were written, with compiler programs to allow the machines themselves to do the conversion to their own (machine) language. Accommodating to the nature of the computer in this way still was not the answer from the scientist's or experimenter's point of view, for there remained an enormous commitment of processing (compiling) and debugging prior to the first feedback of results. Furthermore, it proved necessary to write compilers for many problem fields, which gave this mode of solution a patchwork look. For these reasons, we decided to attack the problem at its roots by changing the fundamental nature, i.e., the organization of the computer itself. We took it as the aim of our work to allow the experimenter to use the computer as directly as possible as an experimental tool. © Copyright 1963 by American Federation of Information Processing Societies.

The emphasis is on compilers. There is no mention of the lowly nearly-machine-language interpreter which requires the user to write a program on a computer code. Three reasons are usually advanced for the employment of compilers. First, it is said that this is a method of teaching the machine to understand the user. Second, compilers are a way of speeding up the coding procedure, for now the user may write his program in a "problem-oriented" language. Third, anyone can learn how to use a computer if he can understand the problem which he has to solve. © 1961 Association for Computing Machinery, Inc. All rights reserved.

This independent organization of arithmetic, sequence control, and memory units give IMP the capacity for Intrinsic Multiprocessing, which can now be characterized by the following properties. (1) Since ACU's are not assigned to SCU's, the ACU needn't stand idle awaiting operand or instruction fetches. (2) If a particular problem happens to contain a segment in which occurrences of one operation, say multiply, are very frequent, at most only that problem need be delayed by that condition;the remainder of the ACU's and SCU's continue operation. (3) The high overall performance of the system is accomplished without any need to depart from strictly sequential programming techniques unless convenient to do so. The n sequence control units can work on different problems if desired. Two further observations about the IMP system: (1) Where it is desired to provide multiple access facilities, the independent organization of SCU's and ACU's enables one to consider a system with many more SCU's than could be afforded if each required its own complete arithmetic unit. (2) It is unnecessary to invest in clever hand-coding or sophisticated compiler-optimization techniques in order to achieve reasonable efficient operation of the system. © 1967 ACM.

Parallel program schemata: A mathematical model for parallel computation 8

8th Annual Symposium on Switching and Automata Theory, SWAT 1967

Many recent design proposals for highperformance computer systems are based on an organization in which many programs, procedures within a program, or instances of the same procedure applied to different data, can simultaneously be in progress. In these systems parallelism becomes a major consideration in problem analysis, the specification of programming languages and the de sign of compiler s and operating systems. Since programming languages currently in use have no explicit provision for representing parallel sequencing, it is necessary to develop new representations of algorithms in order to display various kinds of parallelism and make it easy to take advantage of them. In addition, new questions concerning the analysis and synthesis of a1goriths suggest themselves in connection with parallel computation. Methods will be required for determining the degree of parallelism of given algorithms and for converting algorithms to more highly parallel equivalent forms. Also, the phenomenon of "race s" between computation steps, leading to the possibility of indeterminacy, will have to be studied. © 1967 IEEE.
