Abstract : After a six month evaluation period, in which workstations manufactured by Digital Equipment, Hewlett-Packard, Apollo Computer, Silicon Graphics, Ardent Computer and Stellor were evaluated, an Ardent Titan Superworkstation was purchased. This computer was configured with 64 MB of memory and two processors, both of which have vector-processing capability. The machine also permits sophisticated use of three-dimensional graphics. The Ardent computer was judged to have a better architecture than its competitors, to be more flexible in the method of adding peripherals and to have substantial price/performance advantages. The computer was delivered in July 1989 and is currently being used extensively for computational fluid mechanics research as well as imaging associated with the experimental programs. The purchase cost included new CPU boards which will automatically be installed when available. (kr)
