On-Line Computing With a Hierarchy of Processors Abstract Time shared computer systems have been based upon the two techniques of multiprogramming and swapping. Multiprogramming is based on restricting each program to a portion of the total computer memory. Swapping requires considerable overhead time for loading and unloading programs. To alleviate the size restriction due to multiprogramming, segmentation is employed, resulting in fact in vastly increased swapping. A new system architecture is proposed for time shared computing that alleviates the high overhead or program size restriction. It utilizes a hierarchy of processors, where each processor is assigned tasks on the basis of four factors: interactive requirements, frequency of use, execution time, and program length. In order to study the hierarchical approach to system architecture, the Moore School Problem Solving Facility (MSPSF) was built and used. The study of the manner of operation and the reactions of the users clarified and defined the Hierarchy of Processors system architecture. The Moore School Problem Solving Facility was implemented on second generation equipment, the IBM 7040, and therefore it is not possible to adequately compare the efficiency with third generation computers operating in a swapping mode. -
The Travelers IBM 1401 Exhibit Thematic Presentation, June 1984
THE TRAVELERS IBM 1401 EXHIBIT At The Computer Museum, Bay 3, Floor 5 THEMATIC PRESENTATION Overall The Travelers IBM 1401 Exhibit will illustrate general aspects of business computing in the mid-sixties. Four primary themes will be presented: the use of computers as information processors by businesses, the characteristics of this kind of computer operation, the rise in higher-level languages, and the replacement of punched cards by magnetic memory as the predominant secondary storage medium. The Travelers 1401 will exemplify these themes. In instances where reality does not quite serve the presentation artistic license will be exercized. Computers as Business Tools The use of the 1401 by The Travelers for policy processing and management report compilation will illustrate the general character of problems to which businesses a~plied computers. Charateristics of Computer Operation Batch-processing characterized the operation of computers in the mid-sixties. This reinforced the division between the machine and the programmers. Since only operators were allowed to run programs on the computer, the process of de-bugging a program was long and arduous. This method of operation will be contrasted with the contemporary operation of computers. The 1401 exhibit, by the relative position of the Programmer's Office and the Computer Room, and the contents thereof, will advance this theme. High-Level Languages The predominance of COBOL as the programming language for business illustrates the general move towards using higher-level languages which occured throughout the 1960's. The Travelers 1401 will be presented as being programmed in COBOL. The Fall of the Punched Card and the Ris~ of Magnetic Memory Inflexibility, serial storage, and size will be presented as three of the major problems of punched cards for data storage. -

The Evolution of Econometric Software Design: a Developer's View
Journal of Economic and Social Measurement 29 (2004) 205–259 205 IOS Press The evolution of econometric software design: A developer’s view Houston H. Stokes Department of Economics, College of Business Administration, University of Illinois at Chicago, 601 South Morgan Street, Room 2103, Chicago, IL 60607-7121, USA E-mail: [email protected] In the last 30 years, changes in operating systems, computer hardware, compiler technology and the needs of research in applied econometrics have all influenced econometric software development and the environment of statistical computing. The evolution of various representative software systems, including B34S developed by the author, are used to illustrate differences in software design and the interrelation of a number of factors that influenced these choices. A list of desired econometric software features, software design goals and econometric programming language characteristics are suggested. It is stressed that there is no one “ideal” software system that will work effectively in all situations. System integration of statistical software provides a means by which capability can be leveraged. 1. Introduction 1.1. Overview The development of modern econometric software has been influenced by the changing needs of applied econometric research, the expanding capability of com- puter hardware (CPU speed, disk storage and memory), changes in the design and capability of compilers, and the availability of high-quality subroutine libraries. Soft- ware design in turn has itself impacted applied econometric research, which has seen its horizons expand rapidly in the last 30 years as new techniques of analysis became computationally possible. How some of these interrelationships have evolved over time is illustrated by a discussion of the evolution of the design and capability of the B34S Software system [55] which is contrasted to a selection of other software systems. -

Technology Transfer: the IBM System/360 Case by Emerson W
Technology Transfer: The IBM System/360 Case by Emerson W. Pugh Introduction The term 'technology transfer" is most commonly used within a company to describe the internal transfer of technical knowledge or devices from research to development, from development to manufacturing, and from manufacturing to sales and services. The term is also used to describe the less orderly processes in which new technologies flow backwards in the system (e.g. from manufacturing to research) or laterally (e.g. from one development laboratory to another development laboratory). In academic circles and international conferences, technology transfer is more often used to refer to the transfer of technology from one company to another or between different geographical locations and countries. Multinational companies can be involved in all of these processes simultaneously; and companies in high-tech industries will only survive if they understand and manage these processes effectively. Indeed, this was the case for IBM during the 1960s when it introduced the IBM System/360 line of computers. Defining the Problem The problem IBM faced was the direct result of rapid changes in technologies, combined with dramatic growth in the computer market -- which was itself driven by the rapidly improving cost/performance of critical technologies. The success of the IBM 1401 computer, announced in October 1959, highlighted the problem. Equipped with discrete semiconductor logic circuits and up to 4000 characters of ferrite-core memory, it was the first computer to be inexpensive enough to replace conventional punched card equipment. By the end of 196 1, the number of 1401 s installed in the United States had reached 2,000; this was 25 percent of all electronic stored-program computers installed by all manufacturers to that time. -

A non-profit organization, representing key educational agencies in the state of Minnesota, was established to advise and guide the project. A statewide conference was held under the auspices of the Governor to mobilize interest, to provide and disseminate information, and to do preliminary planning. A status study was conducted which covered all institutions in the state and included hardiare utilized, plans, training of staff and special projects and efforts that might be underway. On the basis of the conference, the status study, and subsequent meetings, a basic overall plan for the coordination and development of information systems in education in the state of Minnesota was completed and disseminated. Appendixes include a report on the conference, the status report, and the resultant state plan.

Administrative History In the autumn of 1955, President Norman Mackenzie appointed a Committee on Automation to investigate "the University's total interest in computers and automation in general". The Committee consisted of approximately 20 members representing most of the research interests on campus and was chaired by E.D. McPhee. At the Committee's first meeting on November 16, 1955, four sub-committees were formed: Departmental Interests and Specifications; Training and Curriculum: Type Equipment; and Library Needs and Resources. The Committee held several meetings and prepared a number of reports on various facets of computerization. -
