Bailey NASA Ames Research Center Moffett Field, California NASA has initiated at the Ames Research Center the vices, a library of aerodynamic simulation models, Numerical Aerodynamic Simulation (NAS) Program. and a rich set of local area network data communi­ The objective of the Program is to develop a cation services. leading-edge, large-scale computer facility, and make it available to NASA, DOD, ~ther Government agencies, industry and universities,. as a neces­ sary element in disciplines. The Program will establish an initial operational capability in 1986 and systematically enhance that capability by incorporating evolving improvements in state­ of-the-art computer system technologies as re­ quired to maintain a leadership role. The NAS Program had its genesis in the efforts of theoretical aerodynamicists at the Ames Research Center during the mid-1970·s. Its purpose was to exploit computational aerodynamic research to im­ prove the basic technology of aircraft and aero­ space vehicle design. The combination of improve­ ments in aerodynamic flow simulation modelling and supercomputer performance have permitted the rapid advancement of computational aerodynamics to the stage where it is practical to address non-linear inviscid flow simulations about complex aerody­ namic configurations, and detailed turbulent flow simulations about simple configurations. The nec­ essary next step in the advancement of computa­ tional aerodynamics is to combine detailed turbu­ lent flow models and complex configurations, to provide the capability to accurately simulate realistic designs over the entire flight envelope. The goal of the NAS Program is to provide the nec­ essary computer throughput, memory capacity, and system architecture to reach this next step. In particular, the NAS Program will achieve a super­ computer capability of 250 million floating-point operations per second sustained throughput and a 256 million-word memory capacity in 1985/86, and a four-fold increase in these capabilities by 1987. This new supercomputer capability includes the Cray-2, which will be integrated into the NAS Processing System Network (NPSN). The NPSN is designed to support supercomputer-generated, large-scale aerodynamic flow simulations with powerful scientific workstations, mass storage facility, high-resolution graphics facility, and high-bandwidth remote communication links to re­ mote sites nationwide. To aid in its productive use, the system will provide unique software fea­ tures including a UNIX™ operating system envi­ ronment across all systems, common graphics ser- 3 CRAY RESEARCH CORPORATE REPORT Don Whiting Cray Research, Inc.
