Vectorization of FORTRAN Programs

In this chapter, we give an introductory survey of the vectorization of computer programs on the CRAY-1 and CYBER 205 vector computers. We place no great emphasis on good programming practices, nor do we present a complete survey of all possible ways to optimally vectorize production codes. Here we shall restrict ourselves to discussing some helpful coding techniques, which are easy to understand and to implement. However, it should be emphasized, that the selection of an appropriate algorithm is generally far more important than fancy programming techniques.
