    Simulation and Cognitive Engineering: The Use of Synthetic Environments to Design and Evaluate Human-In-The-Loop Systems
    Chris M. Herdman, Carleton University

    The Visualization and Simulation (VSIM) Centre at Carleton University supports multidisciplinary research that integrates research in the human sciences with engineering. In the VSIM Advanced Cognitive Engineering (ACE) Lab, synthetic environments of different fidelity are engineered to support the design and evaluation of human-in-the-loop systems. The synthetic environments at the ACE Lab include HLA-enabled helicopter (CF-146 Griffon), general aviation (Cessna 172 type) and Unmanned Air Vehicle (UAV) simulators as well as an automobile simulator. In this talk he will outline a Cognitive Systems framework that we use to guide our research in the ACE lab and I will draw upon specific examples from our aerospace and automotive research to illustrate how simulation plays a critical role in advancing human-in-the-loop systems.

    The Need for Diversity in HPC
    Paul Lu, University of Alberta

    For both hardware and software in high-performance computing (HPC), there are strong trends towards homogeneity. Although there are strong economic, technological, and social reasons behind consolidation in HPC, the lack of a diverse toolbox has some potential, long-term risks. With only a single kind of hammer, will everything look like a nail? If the tools to tackle the hard problems are no longer available, will only the easy problems be solved?

    We examine some of the trends in HPC hardware and software, the tangible benefits that have resulted from consolidation, but also the risks that come from a monoculture.

8:30 - 10:00 Tutorial Session

    An Introduction to DEVS and Distributed DEVS
    Ming Zhang, University of Ottawa

    This tutorial presents fundamental DEVS concepts and applications of DEVS-based modeling and simulation in industry and research. We will discuss how DEVS is well suited to modern software infrastructures and how it compares to non-DEVS modeling and simulation methodologies. In particular, this tutorial will focus on distributed DEVS tools for solving large-scale modeling and simulation problems.

8:30 - 10:00 Tutorial Session

    The Deterministic Global Optimization Algorithm DIRECT
    Layne T. Watson, Virginia Polytechnic Institute and State University

    The deterministic direct search algorithm DIRECT of D. Jones has proven surprisingly practical for engineering design, especially when coupled with a local pattern search algorithm such as MADS by Audet and Dennis. Massively parallel implementations of these algorithms, necessary for realistic engineering and scientific problems, are highly nontrivial. This tutorial will cover the serial DIRECT and MADS algorithms, their parallel implementations, place them in the context of global optimization, and describe recent applications in multidisciplinary design optimization and systems biology.
