 CRAY RESEARCH ANNOUNCES NEWEST VERSION OF UNICOS OPERATING SYSTEM;
 UNICOS 7 CONTINUES INVESTMENT IN PARALLEL PROCESSING
 EAGAN, Minn., Oct. 27 /PRNewswire/ -- Cray Research, Inc. (NYSE: CYR) today announced the availability of the UNICOS 7 product, the newest version of the company's UNIX-based operating system. The UNICOS 7 operating system contains important new features and tools that will allow users to maximize the performance of their Cray Research supercomputers. This is the sixth major update of the UNICOS software, which was originally introduced in 1986.
 "With each release of UNICOS, we improve the operating system's efficiency, reliability and usability for our customers," said Irene Qualters, vice president of software for Cray Research. "This operating system is designed for our full product line, including the new CRAY Y- MP C90 system. UNICOS 7 also is important because it will provide the base development environment and operational support for our MPP system due out next year, which will closely couple MPP (massively parallel processing) technology with our CRAY Y-MP parallel/vector architecture."
 Cray Research was the first supercomputer manufacturer to embrace UNIX, which has since become the industry-standard operating system for scientific and technical computing Qualters noted. "UNICOS is based on AT&T's UNIX system V with Berkeley extensions. Through years of development and testing, UNICOS has grown to be the most powerful production-quality UNIX-based operating system for supercomputers," she said. In addition, she said the new release is easier to install and includes several new features and support tools designed to increase the productivity of both users and system administrators.
 "We are impressed with the way the quality and reliability of UNICOS has increased with each new release, as well as the variety of tools and utilities available in UNICOS 7. These tools enable us to get the most from our Cray Research systems," said John Hirshey, technical support, computer center at Chrysler Corporation, which has several CRAY Y-MP systems and was a beta test site for UNICOS 7.
 The UNICOS 7 operating system continues to lead the industry in multiprocessing capabilities through its Autotasking component, which automatically distributes and concurrently executes a program on all of the central processing units (CPUs) of the system, significantly speeding problem-solving. Today, Cray Research hardware systems have from one to 16 CPUs, the highest level of parallelism available today for production-grade supercomputing.
 UNICOS 7 software contains several new tools to increase the productivity of end users, programmers and system managers. The Application Development Toolset consists of tools that provide program performance statistics in an easily grasped, visual format. In the past, output from such tools consisted of numerical print-outs that needed to be interpreted. The visual output displays of this new product are easier to work with and increase user productivity.
 One of the tools from the Application Development Toolset is ATExpert, an X-Window System-based expert system that analyzes an application's potential parallel performance and displays performance information as an on-screen
plotted graph. The ATExpert tool interprets the data and offers suggested actions to enhance parallel performance. Xbrowse, another toolset component, can speed Fortran source code editing and debugging. This language-sensitive browser provides information at the routine, file, or the whole program level and includes variable tracing and parallel processing analysis information.
 Cray Research has more than 350 systems installed worldwide, more than 90 percent of which currently operate the UNICOS operating system.
 Cray Research creates the most powerful, highest-quality computational tools for solving the world's most challenging scientific and industrial problems.
