The scope of the present book is to offer the most efficient tools for
the vectorization of serial computer programs. Here, by vectorization we
understand the adaptation of computer programs to the special
architecture of modern available vector computers to exploit fully their
potential, which will often result in remarkable performance
improvements. The book is written primarily for users working in the
various fields of computational physics, for scientists as well as for
programmers running their jobs on a vector computer. The text may,
however, also be of value to those who are interested in numerical
algorithms. Although the examples discussed in chapter 9 have been taken
from Computational Fluid Dynamics, the numerical methods are well-known,
and are applied in many fields of Computational Physics. The book is
divided into four parts. After a short introduction which outlines the
limits of conventional serial computers in contrast to the possibilities
offered by the new vector machines, the second part is addressed to the
discussion of some main features of existing computer architectures. We
restrict ourselves to the vector computers CRAY-1S and CDC-CYBER 205,
although, in the meantime, many vector and parallel computers and array
processors are available such as DENELCOR's Heterogeneous Element
Processor (HEP), ICL's Distributed Array Processor (DAP), SPERRY
UNIVAC's Array Processing System (APS), STAR TECHNOLOGIES ST-l00,
FLOATING POINT SYSTEMS' Array Processor (FPS), FUJITSU's FACOM VP-l00
and VP-200, HITACHI's Integrated Array Processor (lAP), HITACHI's S
810/10 and S 810/20 and others.
