SHELL: A Simulator for the Software Test Vehicle of the INFOPLEX Database Computer.

Abstract

The INFOPLEX database computer is a special computer designed for large scale information management. The information management functions are decomposed into a functional hierarchy implemented by a hierarchy of micro-processors. Decentralized control mechanisms are used to coordinate the activities of individual modules in the hierarchy. Before realizing INFOPLEX in hardware, it is essential to validate all the design details via a software test vehicle (STV). A simulator (SHELL) is built to provide the necessary facilities for the operating of this software test vehicle. It has two parts: an event simulator which simulates the operation of the afore mentioned hardware configuration; and an operating system emulator which provides the environment for testing the multi-threading, parallel processing application programs. SHELL is meant to be used as the Control Structure portion of the STV project, which includes two additional parts, the Functional Hierarchy STV and the Storage Hierarchy STV. (Author)
