The problem of optimization of complex systems with discrete structure, reduced to aggregation of elements of the system in a given number of minimally interacting aggregates is discussed. This kind of problem arises, e. g. , in computersystems during segmentation of the program modules, which can be arranged either in main memory (MM) or in external memory structures (FMS). The object is to unite/connect the program modules in segments with following resegmentation in such a way that the number of accesses between MM and EMS is minimized while the total volume of memory modules combined in a segment does not exceed the size of the latter.

Schemacode is an interactive tool that not only helps the user write a program, but also automatically provides documentation for it. The methodology behind Schemacode is based on the control structures that programs generally contain to specify the execution order of statements. Each program can be graphically expressed in terms of four types of actions: sequential, input-output, repetitive, and conditional. Schemacode is based on schematic pseudocode (SPC), which can represent the control skeleton of the program;that is, its structure as well as its flow. An easily acquired language, it is beneficial to both managers and programmers in the development of structured software;its pictorial representation serves as a means of recording, analyzing, developing, and communicating program information.

The examination of classical computer-sort algorithms presented here reveals that some of them can be adapted to work more efficiently than others on programmable calculators. Various sort-algorithms are compared and the difference in their application on a large computer is discussed. Tests performed on a TI-59 calculator using the Quicksort algorithm are described and tradeoffs involved in selecting a sorting algorithm for a calculator are examined.

It is shown that with an integrated system approach to microcomputer development, it is possible to offload many mechanical aspects of a task. The key to an integrated approach is the availability of an editor and realtime debugger that run on a host machine, and operate in such a mode that the machine, and programmer, actually think they are the target system.

The article considers a two-phase closed queuing system that is one of the subsystems of a computer installation, with two devices A and B and two requests. Using this example, it is shown that the use of exponential distributions yields the optimal solutions in terms of phase composition for a system of the given type.

Queuing network models are valuable tools for analyzing the performance of multiprogrammed computers. A generating function approach is used to derive a set of efficient computational algorithms for solving closed queuing network models. Expressions are derived and algorithms are specified to compute the characteristics of closed queuing network models with state-independent and state-dependent stations which have single or multiple job classes. Decomposition and aggregation in queuing networks are also discussed using the generating-function approach. Finally, the results are used in analyzing the performance of a time-sharing and a transaction-processing computer system.
