Infrastructure Support Scientists Workshop

Marek Behr (AHPCRC-UM)

Richard Chait, Director of Army Research and Laboratory Management

In February 1997, the second AHPCRC Infrastructure Support Scientists Workshop took place at the Corps of Engineers, Waterways Experiment Station (CEWES) in Vicksburg, Mississippi. This workshop brought together the infrastructure support scientists working with various Army sites, and the faculty researchers (or their representatives) from the University of Minnesota (UM) and its academic partners. The Workshop gave the support scientists and faculty researchers a chance to update their peers on the progress of their research, and also provided an opportunity for staff scientists who joined the AHPCRC sites since last year to meet.

The Workshop began with opening remarks by CEWES Director Robert Whalin and AHPCRC Director Tayfun Tezduyar. The keynote address was given by Richard Chait, who serves as the Director of Army Research & Laboratory Management for the US Army. Chait talked extensively about future directions for Army-related and Army-funded research, with emphasis on the R&D requirements of the Force XXI and Army After Next programs. Following the keynote speech, Paul Muzio (Network Computing Services, Inc. [NetworkCS]) and Barbara Bryan (NetworkCS) outlined the support resources available to AHPCRC researchers through NetworkCS, and talked about AHPCRC educational activities, which include the Introductory and Advanced Summer Institutes for undergraduate students, as well as other initiatives. Subsequently, the CEWES hosts presented a Three Screen Briefing which gave an overview of CEWES activities and the Station's history.

The technical part of the Workshop began with Marek Behr (AHPCRC-Army Research Laboratory [ARL]) presenting results on parallel modeling of free-surface flows in hydraulic structures, such as the Olmsted Dam, and Lilee Cuff (AHPCRC-Army Medical Research Institute of Infectious Diseases) describing her research on protein docking and vaccine design. Kent Danielson (AHPCRC-CEWES) talked about partitioning strategies for parallel structural mechanics algorithms involving constraints and contact conditions, and Linda Petzold (AHPCRC-UM) described new methods for real-time simulation and control of mechanical systems and their incorporation into the new DASOPT software package.

In the afternoon, Robert Maier (AHPCRC-CEWES) talked about the computational challenges encountered in modeling of pore-scale flows in environmental engineering, and Steve Ray (AHPCRC-ARL) outlined his fluid-solid interaction simulations in interior ballistics research. The following two presentations focused on scientific visualization and user interface of modern software systems. They were given by Eric Schmitt (AHPCRC-ARL), on Distributed Interactive Computing Environment, and by Mike Stephens (AHPCRC-CEWES), on Visualization of the Chesapeake Bay. Later, Marion Harmon and Charles Weatherford, both from AHPCRC-Florida A&M University (FAMU), gave an overview of FAMU research activities, and Kunal Ghosh (AHPCRC-Jackson State University [JSU]) talked about developments at JSU. In the last session of the day, Kosmo Tatalias (AHPCRC-Concepts Analysis Agency) explained hierarchical combat modeling, and Shashi Shekhar (AHPCRC-UM) talked about enabling technology research at the AHPCRC, focusing on algorithms for solving sparse linear systems and on Geographic Information Systems.

On the following day, the Workshop continued with an outline of research activity at Clark Atlanta University (CAU), given by Olugbemiga Olatidoye (AHPCRC-CAU), and with a talk on particle properties of light and radiation in electrodynamics, given by Tepper Gill (AHPCRC-Howard University). Tezduyar presented recent results in the area of advanced flow simulation and modeling at the AHPCRC, and Jeffrey Derby (AHPCRC-UM) talked about analyses of materials processing via high performance computing, as undertaken by his research group. Subsequently, an overview of high-speed turbulent flow research at the AHPCRC was given by Debra Olejniczak (AHPCRC-UM). John Nieber (AHPCRC-UM) gave an overview of environmental modeling activities at the AHPCRC. In the final presentation, Wes Barris (AHPCRC-NetworkCS) and Steve Demlow (AHPCRC-NetworkCS) talked about AHPCRC graphics support. Closing remarks were provided by Walter Sturek (ARL), who serves as the Contracting Officer's Representative for the AHPCRC. After the conclusion of the Workshop, a large group of participants took advantage of an impromptu tour of CEWES visualization facilities, hosted by Stephens. The chief attractions proved to be the 3D ImmersaDesk hardware, and the extensive video editing suite at the Information Technology Lab.
