EDITORIAL FOR SPECIAL ISSUE ON INTELLIGENT METHODS FOR PERFORMANCE ENHANCEMENT IN INDUSTRIAL SYSTEMS VOLUME II: INTELLIGENT SYSTEMS DEVELOPMENT - TOOLS AND METHODOLOGIES

We present a preliminary definition and theory of artificial emotion viewed as a sequential process comprising the appraisal of the agent global state, the generation of an emotion-signal, and an emotion-response. This theory distinguishes cognitive from affective appraisal on an architecture-grounded basis. Affective appraisal is performed by the affective component of the architecture; cognitive appraisal is performed by its cognitive component. A scheme for emotion classification with seven dimensions is presented. Among them, we emphasize the roles played by emotions and the way these roles are fulfilled. It is shown how emotions are generated, represented, and used in the Salt &; Pepper architecture for autonomous agents (Botelho, 1997). Salt &; Pepper is a specific architecture comprising an affective engine, a cognitive and behavioral engine, and an interruption manager. Most properties of the cognitive and behavioral engine rely upon a hybrid associative, schema-based long-term memory. In Salt &; Pepper, emotion-signals, represented by label, object of appraisal, urgency, and valence, are generated by the affective engine through the appraisal of the agent's global state. For each emotion-signal there are several nodes stored and interconnected in long-term memory. Each of these nodes contains an emotion response that may be executed when an emotion-signal is generated. Emotion intensity relates to the activation of the node. It is shown that the Salt &; Pepper architecture for autonomous agents exhibits several properties usually related to emotion: state and mood congruence, compound emotions, autonomic emotion-responses, and different emotion-responses to the same stimulus including the generation of different motives. The implementation of a concrete example is described.     

SOFTWARE ENGINEERING DESIGN METHODOLOGIES AND GENERAL SYSTEMS THEORY

Abstract

The relation between Software Engineering and General Systems Theory is explored. They are found to be dual meta-disciplines which need each other. It is discovered that there is a simple connection between the background variables of Klir's GSPS and Software Design Methodological Viewpoints. This connection motivates a look al the ontological assumptions underlying the two meta-disciplines which underlies the epistemological framework of GSPS. That framework is used to attempt to understand the nature of the different manifestations of software. This leads to an in depth look at the essence of software which in turn leads to the extension of the epistemological lattice of GSPS. The article shows the complex ways in which Software Engineering Methods and General Systems Theory intertwine al the ontological and epistemological levels which causes us to understand both differently than we would have understood them separately. The point of the article is to show how these two meta-disciplines need and intimately involve each other at a fundamental level and in fact co-arise from each other in spite of the fact that one is extremely general and the other extremely concrete. The object is to establish a basis for software engineers and general systems theoriests to learn from each other based on a common framework for understanding Software Systems

SOFTWARE TOOLS FOR MULTIPROCESSOR SIMULATION AND PROGRAMMING

ABSTRACT

Array C Language (ACLAN) is a programming language that extends C by endowing it with structures for programming array processors. ACLAN's two salient features are its machine independence and its ability to handle local processing element memory directly. This article describes ACLAN additions to C, Research in parallel programming with ACLAN is supported by Array C Language Emulator (ACLE), a software package comprising an ACLAN-to-C translator, a library of simulations routines, and array processor specification software. ACLE enables the execution of programs written in ACLAN to be simulated on a conventional sequential computer. Finally, an algorithmic solution for mapping algorithms on hypercube computers is provided.

并行可视化调试工具中检查点使能的研究与实现

与串行程序相比,并行程序调试会遇到新的问题。首先并行程序往往需要长时间运行,从而导致并行程序调试是一个尤其费时的过程;其次并行程序调试过程中,某一次调试出现的错误在下次调试的时候不一定出现,给错误跟踪带来了很大困难。本文针对这两个问题,设计和实现了一个中间件系统,在并行调试工具XMPI中使能BLCR检查点系统的。通过该中间件,在使用XMPI调试大型MPI并行程序的时候,减少调试阶段并行程序运行时间,并且可以更好跟踪并行程序错误,提高并行程序开发效率。
