SPI: an instrumentation development environment for parallel/distributed systems

Abstract

This paper presents an overview of the Scalable Parallel Instrumentation (SPI) tool being developed at Honeywell. SPI provides a complete development and execution environment for developing real-time instrumentation functions for heterogeneous parallel/distributed systems. This includes: C-extensions and development tools for the event-action programming model, run-time support for transparent event-action execution on a heterogeneous distributed platform, and a library of primitives (actions) ranging from real-lime data collection, analysis to graphic display. Concurrent instrumentation functions can be flexibly parallelized/distributed over the heterogeneous platform to selectively analyze and display desired activity at the hardware, OS, IPC, and application levels. SPI is currently operational on a heterogeneous platform of SUN workstations and Intel Paragon.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
