A Tool for Real-Time Performance Monitoring of Parallel and Distributed Systems

This paper presents the concepts, architecture, and features of a tool for instrumenting parallel and distributed systems. This capability will be useful in evaluating alternative architectures and strategies for distributing application software, detecting performance bottlenecks, quantifying and fine-tuning real-time performance, detecting and isolating behavior anomalies, and characterizing the behavior of specific algorithms under desired stimulation conditions. The Honeywell instrumentation system provides a flexible capability for selecting and customizing existing instrumentation functions, synthesizing new instrumentation functions, and tailoring/scaling instrumentation to a particular architecture or application domain.
