ARNOLD AIR FORCE BASE ORDERS SECOND CONVEX C3800 SUPERCOMPUTER

 ARNOLD AIR FORCE BASE ORDERS SECOND CONVEX C3800 SUPERCOMPUTER
 RICHARDSON, Texas, Sept. 10 /PRNewswire/ -- Convex Computer Corporation (NYSE: CNX) today announced that Arnold Air Force Base of Tennessee has ordered a Convex C3800 supercomputer. This is the second order in a multi-year contract to provide Convex C3800 supercomputers, maintenance support, and training for the Arnold Engineering Development Center (AEDC). Announced in October of 1991, this four-year, $14.8 million contract provides for Convex to supply four C3800 supercomputers. The first system was installed in January 1992, and the second system will be installed this month.
 AEDC is the nation's premier flight-simulation complex. With more than 50 facilities, center experts simulate full ranges of flight conditions to be experienced by air- and spacecraft- propulsion systems and aerodynamic configurations. AEDC also performs 64-bit computational fluid dynamics code work.
 "The second C3840 system will primarily be used to support on-line gas turbine, jet-engine testing," said Tom Brown, Air Force director of computer technology at AEDC. "Computer simulation permits quantitative estimates of equipment performance and assessment of the effects of various operating conditions and manufacturing tolerances. Using the Convex supercomputer engineers can analyze a variety of engine design processes such as fluid flow and combustion of the Pratt & Whitney PW-4000 engine and the F-22 Advanced Tactical Fighter F119 engine."
 Computer simulations offer a cost-effective supplement to the traditional practice of building prototype models for experimental testing. Engineers can develop the best designs before prototype construction ever begins. With fewer prototypes being built, the long design and development cycle can be reduced, dramatically decreasing development costs.
 According to Brown, the Convex C3840 installed earlier in the year is being used primarily for computational fluid dynamics. "The system is supporting several large-scale, computationally intensive modeling projects such as the F-15 Seek Eagle Program, the National Aerospace Plane (NASP), and the F-22," he noted.
 The four-processor C3840 systems installed at the center are members of the fastest and most powerful supercomputer family in Convex's C3 Series. The C3800 family features up to eight processors, two gigaflogs of peak performance, and four gigabytes of physical memory. The C3800 system is the first supercomputer to be fully implemented with proven gallium arsenide (GaAs) semiconductor technology. The use of up to 45,000-gate GaAs integrated circuits -- the largest and most sophisticated in the industry -- allowed the Convex design team to increase the speed of the system while maintaining a low-maintenance, air-cooled package, thereby reducing the cost of ownership. Priced from $295,000 to $8 million, all C3 Series systems are upward and downward binary compatible.
 "Both of the Convex C3840 supercomputers play a critical role in analyzing and visualizing the tremendous amounts of data we process," said AEDC Commander, Col. William Rutley. "Without computers of this class, AEDC would not be able to meet the computationally intensive test and evaluation requirements needed to support our customers."
 "The purchase of a second C3800 supercomputer by AEDC clearly demonstrates the success of our high-end C3 Series systems and our credibility in this market," said Terrence L. Rock, Convex chief operating officer. "Customer acceptance of this product continues to be strong. In the past, more than half of our sales have been from existing customers, and we are pleased that this trend is continuing with our C3800 products."
 Convex Computer Corporation, a leading supplier of air-cooled supercomputers worldwide, 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.
