Engineering and scientific subroutine library release 3 for IBM ES/3090 vector multiprocessors

Abstract

The paper by J. McComb and S. Schmidt (1988) described the contents and performance features of the Engineering and Scientific Subroutine Library (ESSL) Release 2. In this technical note, we describe several new features in ESSL Release 3 and discuss some of the techniques that were used to optimize vector and parallel performance.
