STAR Network Distributed Computer Systems Evaluation Results.
Abstract
A software model for executive overhead has been developed for distributed processing with emphasis on ease of software development by isolation of synchronization and other topological details from the TAP tasks. Further, restrictive interfaces have been developed to assist in software validation and fault isolation. Six risk functions were created for design evaluation. Quantitatively, these functions have identified risks associated with distributed processing and central processing designs. Two types of hierarchical topologies have been presented as possible candidates for the BMD Underlay DPS. One topology is constructed from 4 MIPS minicomputers (GE FFP). The second topology is constructed from 1 MIPS microprocessors (IAPX432). The merits of the various topologies are analyzed by evaluating their corresponding risk functions. The BMD Underlay System has been identified as a conceptual hierarchical control and a physical hierarchical resource system. The major characteristics of these hierarchies have been summarized. The negative characteristics of a resource hierarchy are inescapable with the current definition of the BMD Underlay System.
