 First Edition (November 1986)
This edition applies to Release 1.1 of the VS FORTRAN Version 2 Compiler, Library, and Interactive
Debug licensed program (Program Number 5668-806) and to the Engineering and Scientific
Subroutine Library licensed program (Program Number 5668-863) for the MVS/XA operating system
and VM/HPO and VM/XA. Changes are made periodically to the information herein; before using
this publication in connection with the operation of IBM systems, consult the latest IBM System!370
and 4300 Processors Bibliography, GC20-0001, to find out which editions are applicable and current.
References in this publication to IBM products, programs, or services do not imply that IBM intends
to make these available in all countries in which IBM operates. Any reference to an IBM licensed
program in this publication is not intended to state or imply that only IBM's licensed programs may
be used. Any functionally equivalent program may be used instead.
The objective of this book is to help users of VS FORTRAN Version 2
exploit the IBM 3090 Vector Facility and the VS FORTRAN Multitasking
Facility to improve the performance of FORTRAN programs. Vectorization
and multitasking are complementary methods that can be applied in the
same program to improve performance.
The IBM 3090 Vector Facility is a hardware feature that provides
high-speed computation particularly suitable for scientific and engineering
applications. The key software for this facility is the VS FORTRAN
Version 2 Compiler, which can generate object code that uses the Vector
Facility. VS FORTRAN Version 2 also provides multitasking, which lets a
single program use several processors in a multiprocessing system
Another important program provided to take advantage of the 3090 Vector
Facility, is the Engineering and Scientific Subroutine Library (ESSL).
