The interface between the host computer and an intelligent graphics terminal and the optimization of functional responsibilities of each become increasingly important in a time-sharing computer-aided design environment. This paper describes the implementation of the ACM/SIGGRAPA Core System on a DEC GT42 (W/PDP 11/10) and the CDC Cyber 74 as host computer.

SIGMUS is a system written in STANDARD FORTRAN IV which may be used to generate simulators in the form of STANDARD FORTRAN IV programs for arbitrary multiprocessor systems. In particular, the following characteristics distinguish SIGMUS from similar developments: simulation of parallel processes of any type and simulation of system models of any abstraction level are possible;effectivity optimization through selection options between runtime-bound, memory space-bound and statistics-bound sumulator variants is offered. In analogy to real systems consisting of modules, the generated simulation systems consist of simulators for these modules. Real subsystems may be connected to the simulators.

A recursive algorithm is given for converting limited-entry decision tables to optimal computer programs in terms of execution time of the resulting programs. The algorithm requires much less than 3**n minimizations, where n is the number of conditions, while dynamic programming techniques require 3**n ones.

Software-development systems for microprocessors can be put together with special off-the-shelf modules at considerable cost savings. The boards can be assembled into advanced floppy-disk-based software development systems or low-cost, simple paper-tape or cassette-based systems. Even the most advanced system requirements are readily accommodated.

The paper briefly describes the requirements for future computers and sets some guidelines for designing the future computersystems. It draws the conclusion that future computers should be different in many respects from today's in terms of their capabilities to: (1) represent and store language and knowledge in nonprocedural form, (2) perform the deductive/inductive inference based on stored knowledge, (3) generate programs from a nonprocedural form of information, (4) deal with a large amount of data, and (5) execute programs very rapidly.

Given a sequence of tasks to be performed serially, a parallel algorithm is proposed to accelerate the execution of the tasks on an asynchronous multiprocessor by taking advantage of fluctuations in the execution times of individual tasks. A parallel program requiring no critical section is given to implement the algorithm and its correctness is proved. A spacewise more efficient implementation which requires the use of critical sections is also given. An analysis is presented (for both implementations) to estimate the speed-up achievable with the parallel algorithm. When the execution times are exponentially distributed, and no critical section is used, the algorithm with k processes yields a speed-up of order k** one-half .

Many statistics kept during the software development of an international switching system were used to analyze and evaluate the software development methodology employed during the project. The purpose of this paper is to present some of the results obtained from the analysis and evaluation of the methodology. This paper also addresses the question of why statistics should be kept and analyzed and defines some of the key concepts employed by the methodology.
