NASA WILL USE POWERFUL CONNECTION MACHINE TO SOLVE GRAND CHALLENGE PROBLEMS IN AEROSCIENCES

 CAMBRIDGE, Mass., Feb. 4 /PRNewswire/ -- Thinking Machines Corporation announced today that the NASA Ames Research Center at Moffet Field, Calif., has acquired a Connection Machine-5 supercomputer. The addition of the highly parallel CM-5 hardware and software will expand their supercomputing environment, and allow them to move towards their objective of solving the Grand Challenge problems in computational aerosciences.
 NASA created the Numerical Aerodynamic Simulation (NAS) program to focus resources on solving critical problems in aeroscience and related applications, by utilizing the power of the most advanced supercomputers. The NAS program, which is based at NASA Ames Research Center, also serves as a pathfinder in integrating supercomputing technologies. In its pathfinding role, NAS addresses many of the most challenging problems in high speed computing. Solutions to these problems benefit other users of high performance computers, both in government and industry. Their long-term goal is to provide the nation's aerospace research and development community with high- performance, operational computing system capable of simulating an entire aerospace vehicle system within a computing time of a few hours. The successful solution of this Grand Challenge problem will require computer systems that can perform the required computations at the sustained rate of one trillion floating point operations per second (one Teraflops).
 NASA's CM-5, with 128 processing nodes, four Gigabytes of memory, and 50 Gigabytes of mass storage in a Scalable Disk Array, will be used to attack some of the most important computational problems now facing computational aerophysics. The increased memory and power of the CM-5 will permit running larger applications than previously possible.
 The CM-5 is a massively parallel production system, based on high- volume parts with numerous tools, a highly optimized software library to increase user productivity, and a sophisticated integrated parallel I/O system. The CM-5's parallel I/O software is used to interact with the parallel file system, as well as with external HIPPI and serial pipes for communication with other computer servers and workstations.
 CMSSL, the Connection Machine Scientific Software Library, is a highly optimized set of mathematical and communications routines that can be used to achieve high performance. In addition, through CM/AVS, which adapts and extends AVS, from Advanced Visualization Systems, Inc., there is a rich distributed visualization system on the CM-5. This visualization system allows users to easily and quickly display the results of their CM-5 computations on a variety of different graphics workstations.
 In addition to the work sponsored by NAS, the CM-5 will be used by scientists participating in the Computational Aerosciences (CAS) element of NASA's High Performance Computing and Communications (HPCC) program. The CAS includes two Grand Challenges: high-performance aircraft and high-speed civil transport. The NAS Systems Development and Computational Services branches will be responsible for integrating the CM-5 into the NAS network, in direct support of scientists nationwide working on these Grand Challenge problems.
 The computer software developed in the course of these research efforts will be made available to the U.S. academic and industrial communities.
 Thinking Machines Corporation is the world leader in the design, development, and manufacturing of highly parallel supercomputers. The company is headquartered in Cambridge, Mass., with offices worldwide.
