The Engineering and Scientific Subroutine Library (ESSL) provides FORTRAN, Assembler, and APL2 application programmers with a high-performance set of mathematical subroutines which take advantage of the performance gains offered by the IBM 3090 Vector Facility. This paper describes the contents of ESSL and presents some of the techniques that were used to develop high-performance vector subroutines. Other key design considerations such as accuracy, ease of use, and error handling are also discussed. This information should be useful to anyone developing programs for the IBM 3090 Vector Facility.
