Abstract:

This report summarizes a project entitled The Enhancement of Datamodule 1. The focus of this project is to study the Datacomputers MARILL and STERN performance in its role as a datamodule in SDD-1 and as a DBMS in other command and control applications. The goal of this study is to produce a set of potential performance enhancements and an analysis of their expected effect on overall Datacomputer performance. Some of the proposed enhancements would be subsequently implemented in the Datacomputer. During the reporting period, the model of Datacomputer performance constructed previously during this project was used to analyze performance in the Advanced Command and Control Architecture Testbed ACCAT. The Datacomputer was instrumented to produce extensive performance data at runtime. The results of this work have indicated which parts of the system are bottlenecks and this, in turn, is suggesting potential enhancements. In addition, the instrumented Datacomputer has been used in other performance work for ARPA.
