To use a vector processor efficiently, the most important point is to increase the vector processing ratio of a problem. But, through the process of coding the problem, it is usual to decrease the parallelism of the problem. And the lost parallelism cannot be restored to the former level. The reason for this fact is that the parallelism of the problem depends largely on the algorithm and programming language used. This paper describes the process of coding and the cause of the decreasing parallelism. The selection of the programming language is the key point in the effective use of vector processors. Various kinds of language systems have been developed and are used for vector processors. Most of these language systems are based on standard FORTRAN, since FORTRAN is the main programming language used in the scientific and engineering fields. These language systems can be classified as follows: (1) Procedure oriented programming language i) Standard FORTRAN - Automatic vectorizing compiler method - Building block method ii) Extended FORTRAN - Vector (Array) processing language - Architecture oriented language (2) Problem oriented programming language In this paper, we present the characteristics of these language systems with examples, and discuss the merits and demerits of each. |
