 CONVEX, THE LEADER IN VISUAL SUPERCOMPUTING,
 SUPPLIES SUPERCOMPUTER POWER TO SIGGRAPH SHOWCASE
 RICHARDSON, Texas, July 28 /PRNewswire/ -- A Convex C3400 system, the only supercomputer and the largest computing platform in the SIGGRAPH '92 Showcase, has been selected by a majority of the showcase exhibitors to run their applications, Convex Computer Corp. (NYSE: CNX) announced today. Showcase '92 demonstrates leading-edge visualization research and applications that rely on high performance computing and high-speed communications.
 The C3440, Convex's mid-range C3 Series supercomputer, is an air- cooled, four-processor system with 800 megaflops of peak performance and two gigabytes of physical memory. The system is boosting response time, storage capacity, and input/output capabilities for numerous demonstrations in the showcase. One such application running on the Convex C3440 supercomputer during the showcase, is a demonstration of a distributed virtual wind tunnel supplied by NASA Ames Research Center, Moffett Field, Calif.
 According to Steve Bryson, a senior design software engineer at NASA Ames, this demonstration shows a distributed shared virtual environment for visualizing three-dimensional unsteady fluid flows. The exhibit involves two complete virtual environment stations networked to the Convex supercomputer. Each station consists of a head-tracking display, data glove, workstation, and video projection screen. Two expert users, one at each station, share the same virtual environment to visualize the same flow data in a cooperative way. Researchers use a combination of visualization tools to simulate particle motion in the fluid flow. This simulation demonstrates pioneering techniques for interactive, computational fluid dynamics research.
 Convex is also demonstrating several graphics capabilities in its booth at the show that expand the supercomputing-based visualization options available on the C3 Series. These include ConvexAVS, PEX Interoperability, and software demonstrations of PV-Wave and IDL.
 ConvexAVS is a complete visualization solution that provides an interactive environment for scientists, engineers, and technical professionals to use advanced graphics and imaging techniques without graphics programming. ConvexAVS is the company's implementation of the widely accepted standard Application Visualization System(AVS). With ConvexAVS, researchers can visualize supercomputer applications in areas such as computational chemistry, image processing, molecular biology, fluid dynamics, mechanical engineering, and geophysics.
 "ConvexAVS is a powerful merger of supercomputing and workstation environments that distributes visualization across a wide range of desktop graphics devices integrated with Convex systems," said Paul M. Lambert, graphics product manager at Convex. "Users can access full supercomputer visualization of large data sets from their desktops, through color X terminals, PEX terminals, or workstations with specialized graphics features."
 According to Lambert, the interactive capabilities of ConvexAVS allow researchers to gain direct graphics feedback from their computations, enabling immediate data adjustments. This accelerates the process of design analysis and simulation to dynamically shorten product development time. "In the MCAE arena, visual interfaces to finite element analysis tools, like ABAQUS, allow engineers to gain new insights into their results through special visualization techniques," said Lambert. "Special features are also incorporated into ConvexAVS for viewing the results of computational chemistry simulations. Included are filters for viewing output from Gaussian 90 or 92, and MOPAC 6.0, and a tool for predicting and viewing protein structures.
 Show attendees can view ConvexAVS demonstrations in the International AVS Center (IAC) booth as well as in the Convex booth. The IAC, located at the North Carolina Supercomputing Center in Research Triangle Park, is an organization designed to provide a forum for advancement of visualization techniques. The IAC gives users access to other users' software, public domain software, and new technologies. A network connection between the Convex and IAC booths links a Convex C3440 and a SHOgraphics PEXstation 1/SX.
 PEX Interoperability is also being demonstrated throughout the exhibition hall. PEX, an extension to the X Window System, is a standard protocol for communicating three-dimensional graphics over networks of heterogeneous systems. In February of 1992, 19 technology companies opened the first PEX Interoperability Center(PEX-IC), located at Convex Computer Corporation's headquarters.
 To fully demonstrate PEX Interoperability between heterogeneous workstations and terminals, hardware has been linked in booths from eight separate manufacturers. Participating in the SIGGRAPH interoperability demonstration are Convex Computer Corporation (No. 1744), Digital Equipment Corporation (No. 1316), Evans & Sutherland (No. 1729), Hewlett-Packard Company (No. 1715), IBM Corporation (No. 1329), Network Computing Devices (No. 961), SHOgraphics (No. 756), and Sun Microsystems Computer Corporation (No. 1322). Systems at each booth are networked and share the same 3D applications, demonstrating the unique ability of PEX to distribute 3D applications across diverse hardware and software platforms.
 Early this year, Convex announced availability of two separate visualization software packages on Convex C3 supercomputers: PV-WAVE and IDL.
 PV-WAVE Command Language is the flagship product of Precision Visuals, Inc., Boulder, Colo., the leading worldwide supplier of Visual Data Analysis (VDA) software. VDA has proven to be an effective tool for Convex customers in market areas such as government/aerospace, petroleum and advanced research, which have previously relied on workstation versions of PV-WAVE. Customers can couple the large memory, high speed I/O, and fast compute features of Convex systems with the VDA capabilities of PV-WAVE to handle the huge quantities of data typical of visualization problems today.
 IDL (Interactive Data Language), the scientific software package from Research Systems, Inc. (RSI), Boulder, Colo., is a complete, integrated environment for the analysis and visualization of scientific data. Its comprehensive mathematical analysis and graphical display capabilities assist more than 10,000 scientists and engineers in major national laboratories, universities, and commercial institutions worldwide. The IDL software available on Convex systems allows users to solve problems too large to be handled by even the highest performance workstations available today. Scientists now have the power to create prototypes on their workstations and, without change, move their program to a Convex supercomputer for full-scale computation.
 Convex Computer Corporation, a leading supplier of supercomputers world-wide, markets its products primarily to scientific, engineering, and technical users for a wide variety of applications in areas such as seismic processing, reservoir simulation, computational chemistry, computer-aided engineering, image processing, aerospace simulations, and molecular biology. Convex, which is listed on the NYSE with the symbol CNX, has sold more than 1,050 systems to nearly 600 customers in 44 countries. The systems are sold and serviced through direct sales and an extensive distribution network.
