This paper describes some aspects of the implementation of our Data Distribution Tool (DDT), which accepts programs written in Fortran77 and obtains alignment and distribution HPF directives for the arrays used in the program. In particular, we describe the phases of the tool which analyze reference patterns in loops, record preferences for alignment and obtain the alignment functions. These fu...

uring initial conversations about the topic of this article, it became evident that we can't identify the top compiler algorithm of the century if, as the CiSE editors originally intended, we consider only the parsing, analysis, and code optimization algorithms found in undergraduate compiler textbooks and the research literature. Making such a selection seemed, at first, the natural thing to d...

The investment in code written in the Fortran language over the last four decades means that there is a vast amount of legacy code written to various standards and incorporating numerous vendor extensions to the language Meanwhile the new For tran standard adds many attractive new features to the language while retaining compatibility with Fortran This paper shows how the NAGWare f Tools may be...

Recently, Cheng in 1993 introduced the C” programming language. C” is designed to be a superset of C with all the programming features of FORTRAN. Formulas with dual numbers can be translated into CH programming statements as easily as formulas with real and complex numbers. In this paper we will show that both formulation and programming with dual numbers are remarkably simple for analysis of ...

Representing a potentially infinite indexed collection of data is a handy abstraction in a number of programming situations. Computational scientists routinely try to finess this notion by allocating an array of some “large enough” size, and (in a perhaps delicate move) re-allocate if it is not large enough. Even if one is aware of some direct implementation of infinite stream/pipe programming ...

The Connection Machine CM-5 supports both SIMD and MIMD programming modes. The SIMD mode is simulated over the MIMD mode. This simulation is likely to lead to a loss of performance in SIMD programs. This paper describes the design and implementation of benchmarks which were used to bring out the diierence in speed between the two programming modes with CM Fortran and message-passing Fortran. Tw...

Th is section surveys the history of instruction set architectures over time, and we give a short history of programming languages and compilers. ISAs include accumulator architectures, general-purpose register architectures, stack architectures, and a brief history of ARM and the x86. We also review the controversial subjects of high-level-language computer architectures and reduced instructio...
