The vectorization of ITPACK 2C
ITPACKV 2D is an adaptation for vector computers of the ITPACK 2C software package for solving large sparse linear systems of equations by adaptive accelerated iterative algorithms. This paper describes the techniques used to vectorize the iterative algorithms in the ITPACK 2C package for the Cyber 205 and Cray X-MP vector computers. The resulting package was named ITPACK 2D. Results of experiments using ITPACK 2C and ITPACKV 2D are given, including a comparison of megaflop rates and timings for two model problems. 21 refs., 7 tabs.
