The AFIT-ASD Cray System, a virtual communications capability from the AFIT School of Engineering to ASDs Cray computer, was studied, created, and evaluated. The SADT design, detailed design, and System program code are included in the study. A user enters the Systems user command sendcray which initiated the users input file to the central AFIT host computer. The input file is then sent first to the Cyber, which is a front-end to the Cray, and then to the Cray itself where the input is processed. Output from the Cray is sent to the Cyber and then back to the AFIT central computer. Finally, the output, with an accompanying job log file, is transferred to the user at the originating AFIT host computer. The System uses a combination of 4.2 BSD UNIX, Cyber NOS, and Cray operating system commands, and makes use of an AFIT Ethernet network and a VAX-UNIXCyber HASPmodem link. The System operates over a series of UNIX C-shell programs, most of which are executed automatically. The System provides the user with simple, error-free, and automatic access to the Cray, with the potential of improved turnaround time for compute-intensive jobs at AFIT. Thesis
