STAP performance on a Paragon/sup TM//Touchstone system

Honeywell's Embedded Touchstone and Rugged Touchstone systems are COTS-based, hardware equivalent and software compatible manifestations of the Intel Paragon XP/S Supercomputing System. The Paragon/sup TM//Touchstone system is a robust, massively parallel processing architecture capable of supporting a wide range of implementation paradigms for DoD, DoE, and NASA applications. All applications, but airborne and space-based applications in particular can benefit from the highest possible execution efficiency because execution efficiency cost. This paper describes the performance obtained from the implementation of several STAP (space-time adaptive processing) benchmarks and the Real-Time Multi-Channel Airborne Radar Measurements (RTMCARM) application on Paragon/sup TM//Touchstone processing systems using a high level, data parallel, data flow approach. Demonstrated performance is discussed in terms of end-to-end latency, speedup, high sustained throughput, high sustained implementation efficiency, high compute resource utilization efficiency, scalability, software portability and software productivity improvement using Honeywell's configurator and data flow shell tools.
