An examination is made of a problem of distributing computational resources of a computer in a calendar period and an algorithm is presented for solving it. This algorithm takes into account such features of contemporary computers as the possibility of simultaneous processing of many jobs in a multiprogram regime.

Program documentation has become fundamental both internally (for production and maintenance) as well as externally (for revision and data security needs). The actuality, validity and completeness required can hardly be provided by conventional methods. This paper points out some ways of using the computer for documentation and introduces the software package DOKU which exploits many of these ideas.

The Bell System communications network is claimed to be the most complex electronic system ever implemented, and the craftsmen who maintain it depend heavily on the availability of high quality documentation. A computer based documentation system - MAGIC - was produced to facilitate the rapid preparation and editing of technical documentation with high cost-effectiveness over traditional manual publication methods. The MAGIC system consists of refresh interactive display terminals for creation and editing of documentation data pages, a data-base management computer, and an electronic phototypesetter.

New and efficient means must be made available in order to enable network engineers to meet the demands made by public utilities on data processing for the fulfilment of their technical tasks. The decisive point is to create a technical information system comprising network calculation, line cadaster control and network data base management. The capability of Siemens' BETINA program system to solve such problems is described.

The input/output (I/O) request characteristic, which is one of the fundamental characteristics for computer system performance evaluation, is measured and analyzed. Measurement is accomplished by a hardware monitor system. The system program addresses corresponding to I/O request events are traced and then analyzed to obtain the I/O request interval distributions for various programs. Measurement data are obtained from an operating computer system by random sampling.

A closed queuing network (QN) that simulates a multiprogrammed computer with two streams of tasks is investigated. Recursive formulas are obtained for the stationary probabilities, these being expressed in terms of the probabilities p//i//0 (i equals 0, 1,. . . , n) determined by solving a system of n plus 1 equations. It is shown how to simplify the calculations in particular cases.

The paper gives an evaluation of the probability of the reduction in the number of operators of ordering (sorting) when ordering is carried out by the method of triangles. The evaluation is carried out with a comparison of maximal and minimal elements of subfiles as ordering statistics. As a result, a transformation of the method of triangles is envisioned.

As multiple computersystems become more widely accepted, the importance of parallel programming increases. Approaches to the design and analysis of parallel algorithms are investigated. Through several examples the importance of interprocessor communication in parallel processing is demonstrated. Various techniques that are applicable in the design and analysis of parallel algorithms are examined with emphasis on those techniques that incorporate communication aspects. A discussion is outlined for several models of synchronous and asynchronous parllel computation and their use in analyzing algorithms. Relatively primitive methodologies for designing parallel algorithms are discussed and the need for more general and practical methodologies is indicated.
