Elint in Lamina: application of a concurrent object language

Abstract

A b s t r a c tThe design and performance of an "expert system" signai interpretion application written in a concurrent objectbased programming language, LAMINA, is described together with a synopsis of the programming model that (orms the foundation of the language. The effects of load balancing and the iimits imposed by task granularity and message transmission costs are studied and their consequences to application performance are measured over the range of one to 250 processors as simulated in SIMPLE/CARE, an extensively instrumented simulation system and computer array model.
