CREWES Project computer systems

Catherine E. (Tina) Howell, Henry C. Bland

The CREWES Project at the University of Calgary has a broad array of dedicated hardware and software in use. Hardware and software are available for many areas of geophysical research, especially seismic. The computer systems are being used to make models, load data, process data, interpret results, graph, analyze, display, print, and plot.

The main processing system has been enhanced during the past year by a processor upgrade, which doubled the speed, and by completion of the installation of network software. Use of the network has developed to the point where data exchange is simple and efficient between most local software and hardware platforms. The network is also providing CREWES with a method of exchanging information internationally.

The main processing system is an IBM 4381 running the MVS/XA operating system with IBM peripherals . Western Geophysical Canada's complete processing system is in use. IBM and Western Geophysical are continuing to provide and to upgrade their support of the CREWES Project. In addition to the IBM mainframe there are two IBM RT workstations, a Sun workstation, a Perkin-Elmer minicomputer, several PC's, and two Apple Macintoshes. Software is being developed using FORTRAN and C - languages available on the microcomputers, workstations and the main IBM processor. The 2D and 3D Landmark interpretation package is available on an IBM RT. UNISEIS and SIERRA are two of the modeling packages in use. Many additional communication, graphing, windowing, analyzing, word processing, and geophysical tools are also in use.
