Abstract

The research project reported in this paper is the result of a joint grant from Texaco and Control Data Corporation. The focus of this project was the development of a vectorized version of the two dimensional elastic forward modeling algorithm developed by Kosloff and Reshef (1982). The program was designed for the CDC CYBER 205, and implemented on Texaco’s installation. Timings obtained for Kosloff’s implementaion on the RCL VAX 11/780 with an attached FPS-100 array processor indicate that the vectorized version is approximately 900 times faster on a CYBER 205.
