Computing capabilities at Argentine and Chilean universities

The author reports on a trip to universities in Argentina and Chile during November 1968, describing university conditions and computing activities. As elsewhere, these universities are experiencing student discontent with the status quo and the solutions they are attempting contrast: Argentina is excluding students from participating in university government; Chile is allowing such participation. University computing service and academic activities are limited. The number of computers is small and so is the capacity, none larger than an IBM 360/40; with some exception, computing science academic programs are rare. This situation is by no means attributable to those responsible for computing developments, who strive for excellence; rather the “system” is hard to overcome. Universities, especially those with strong European traditions, adapt slowly to new academic resources and disciplines; superimposed are the severe technological and economic constraints of the developing nation. Consequently, in the absence of conscious government emphasis on strengthening computing capabilities, future progress may be retarded.

Introducing computing to smaller colleges and universities—a progress report

By technical means that are now routine, computer service for smaller colleges and universities can be provided by remote terminals of a central facility. Access, however, is not enough—effective organizational and educational methodology for introducing computing at such institutions must also be developed. The experience of two years with a statewide network involving 41 institutions is discussed. Lessons include the importance of a separate organization representing the small colleges, the necessity for on-campus training for the institutions, the need for some special programming and documentation to support such users, and the development of curriculum by evolutionary means.

Clarification of Fortran standards—initial progress

In 1966, after four years of effort, FORTRAN became the first programming language standardized in the United States. Since that intital achievement, study and application of the standard specifications have revealed the need for maintenance of the standards. As the result of work intiated in 1967, as initial set of clarifying interpretations has been prepared. The nature of the maintenance, corrections to the standard specifications, and completed interpretations are reported.

An automatic grading scheme for simple programming exercises

A discussion is given of alterations that were made to a typical university operating system to record the results of programming exercises in three different languages, includeing assembly language. In this computer-controlled grading scheme provision is made for testing with programmer-supplied data and for final runs with system-supplied data. Exercises run under the scheme may be mixed with other programs, and no special recognition of exercises by the operators is necessary.

Data communications control procedures for the USA standard code for information interchange

This proposed American Standard has been accepted for publication by USA Standards Committee X3, Computers and Information Processing. In order that the final version of the proposed standard reflect the largest public consensus, X3 authorized publication of this document to elicit comment and general public reaction, with the understanding that such a working document is an intermediate result in the standardization process and is subject to change, modification, or withdrawal in part or in whole. Comments should be addressed to the X3 Secretary, Business Equipment Manufacturers Association, 235 East 42 Street, New York, NY 10017.—E. L.

Some criteria for time-sharing system performance

Time-sharing systems, as defined in this article, are those multiaccess systems which permit a terminal user to utilize essentially the full resources of the system while sharing its time with other terminal users. It is each terminal user's ability to utilize the full resources of the system that makes quantitative evaluation of time-sharing systems particularly difficult. Six criteria are described which have been successfully used to perform first-level quantitative time-sharing system performance evaluation.

The role of programming in a Ph.D. computer science program

In this general paper the role of programming in advanced graduate training is discussed. Subject matter related to programming as well as programming per se is considered. The importance and application of formalism are considered and also the need for good empirical experimentation. A brief outline for a sequence of courses is included, and subject headings that have been obtained from an extensive bibliography are given. A bibliography of programming references is included.

A comparison of batch processing and instant turnaround

A study of the programming efforts of students in an introductory programming course is presented and the effects of having instant turnaround (a few minutes) as opposed to conventional batch processing with turnaround times of a few hours are examined. Among the items compared are the number of computer runs per trip to the computation center, program preparation time, keypunching time, debugging time, number of runs, and elapsed time from the first run to the last run on each problem. Even though the results are influenced by the fact that “bonus points” were given for completion of a programming problem in less than a specified number of runs, there is evidence to support “Instant” over “Batch”.

The AED free storage package

The most fundamental underlying problem in sophisticated software systems involving elaborate, changing data structure is dynamic storage allocation for flexible problem modeling. The Free Storage Package of the AED-1 Compiler System allows blocks of available storage to be obtained and returned for reuse. The total available space is partitioned into a hierarchy of free storage zones, each of which has its own characteristics. Blocks may be of any size, and special provisions allow efficient handling of selected sizes, control of shattering and garbage collection, and sharing of physical space between zones. The routines of the package perform high level functions automatically, but also allow access and control of fine internal details as well.

ARPA: a visible means of support

The Advanced Research Projects Agency has probably done more to lift computer science from other disciplines and to put it on its own feet than any organization inside or outside of government. Even today, when support of computing is spread throughout the government, ARPA is practically alone in its belief that computing deserves to be a separate discipline. Ironically, the computer profession knows little about this friendly benefactor.

Changes in government procurement policies

Several years ago there was an attempt in Washington to place the selection of government computers in a central, highly placed office. Individual government agencies, led by the Department of Defense, successfully beat back this attempt. Today, two years later, it looks as though other forms of centralization are being worked into the government fabric at lower levels, one in the Department of Defense, another in the General Services Administration.
