This paper describes a vectorizing Fortran compiler for the IBM 3090 Vector Facility. Opportunities for vectorization investigated for eight levels of DO-loop nesting. Recurrences in inner loops do not prevent vectorization of outer loops. A least-cost analysis determines from the opportunities identified which specific vectorization will result in the fastest execution. The normal optimization phases of the compiler produce much of the information needed for the vectorization analysis.
