Programming in VS Fortran on the IBM 3090 for maximum vector performance
The IBM 3090 - a high-performance, general-purpose computer - when enhanced by the Vector Facility and the VS Fortran Compiler Version 2 with vectorization capabilities becomes a powerful tool for large-scale scientific and engineering computations. This article illustrates programming techniques necessary for high performance on the 3090 and demonstrates that VS Fortran programs can achieve near maximum execution rates. The ideas behind these techniques apply to other vector processes as well. Implementation, however, may differ significantly depending on machine organization.
