    Introductory principles of program performance in virtual storage have been presented to give a perspective of the virtual environment for systems designers and programmers. It is recognized that the list of guidelines presented is not comprehensive as many more useful techniques will be developed as experience is gained with virtual storage systems. It is hoped that these program design considera... View full abstract»

    Decision tree analysis is a formal methodology by which complex decision problems can be decomposed into sequences of contemplated decisions (or acts) and their uncertain consequences (or events). The analysis is naturally and conveniently depicted in the form of a tree, where the branches emanating from a given node represent alternative acts or events. Anticipated cash flows and probabilities ar... View full abstract»

  • Describing data in computer networks

    Programmers are quite accustomed to describing data they use: where to find it, what devices are involved, the layout of the data, what to do with it after the job is complete, processing techniques employed, and often a great deal more. The reason data is so described is that, nowadays, programs call upon a great many other programs for assistance. All sorts of common-place functions that the pro... View full abstract»

  • Centralization or dispersion of computing facilities

    Publication Year: 1973, Page(s):283 - 301

    We have presented a number of considerations that are pertinent to the degree of centralization or dispersion of computing facilities within an organization. We have argued that costs can be associated with the major factors involved so that effects of proposed changes in dispersion can be assessed quantitatively, if only approximately.

    Developers of computer systems are frequently faced with a choice among several possible implementations of a given function. Similary, the operator of a computer system faces a choice in setting adjustable parameters built into the system. In each case, the alternative that optimizes system performance is sought. While analytic or simulation models may sometimes assist in making the choice, it is... View full abstract»

    The Checkout Compiler was developed to work in harness with the Optimizing Compiler to provide an exceptional level of support for the PL/I language. The Checkout Compiler was designed particularly to increase the productivity of programmers in their development of programs. In meeting this objective, certain constraints had to be taken into consideration, chief of these being compatibility with t... View full abstract»
