The advantages of Fortran 90

John Reid
1992 Computing  
It was finalized (down to the last editorial detail) on 11 April 1991, published as an ISO Standard in August 1991, and the first compiler is now on the market.  ...  Fortran 77 is the most widely used language for scientific programming. Its long-awaited revision is now called Fortran 90.  ...  I would like to thank them both for carefully checking the original draft and making many helpful comments.  ...

Advanced geometric modeler with hybrid representation

Changgui Yang, Yujian Chen, Jiaguang Sun
1996 Journal of Computer Science and Technology  
The language now contains features for array processing, abstract data types, dynamic data structures, objectoriented programming and parallel processing.  ...  Individual procedures may be compiled separately or grouped into modules, either way allowing the convenient construction of very large programs and procedure libraries.  ...  This version of Fortran was to be known as High Performance Fortran (HPF), and Fortran 90 was chosen as the base language.  ...

A review and analysis of Fortran 8x

Brian T. Smith
1988 ACM SIGNUM Newsletter  
Such a program should generally compile and execute under a Fortran 8x compiler in the same manner as under a Fortran 77 compiler.  ...  In addition to data, modules may contain procedures and procedure interface descriptions.  ...  Modules Fortran 77 has four kinds of program units: a main program, a subroutine, a function, and a block data subprogram. Fortran 8x adds a fifth: a module.  ...

VFC: The Vienna Fortran Compiler

Siegfried Benkner
1999 Scientific Programming  
High Performance Fortran (HPF) offers an attractive high‐level language interface for programming scalable parallel architectures providing the user with directives for the specification of data distribution  ...  and delegating to the compiler the task of generating an explicitly parallel program.  ...  Acknowledgment The author would like to thank Viera Sipkova, Bob Velkov and Kamran Sanjari for their work in implementing the VFC compiler, and Guy Lonsdale and George Mozdzynski for providing the MPI  ...

Test-driven coarray parallelization of a legacy Fortran application

Hari Radhakrishnan, Damian W. I. Rouson, Karla Morris, Sameer Shende, Stavros C. Kassinos
2013 Proceedings of the 1st International Workshop on Software Engineering for High Performance Computing in Computational Science and Engineering - SE-HPCCSE '13  
This bottleneck will be resolved in the future by new collective procedures in Fortran 2015.  ...  Our scaling studies show that the bottleneck in the performance was due to the implementation of the collective sum procedure.  ...  Array syntax gives the compiler a high-level view of operations on arrays in ways the compiler can exploit with various optimizations, including vectorization.  ...

PCRC-based HPF compilation [chapter]

Guansong Zhang, Bryan Carpenter, Geoffrey Fox, Xiaoming Li, Xinying Li, Yuhong Wen
1998 Lecture Notes in Computer Science  
In particular, we d i scuess the design and implementation of an HPF compilation system based on PCRC runtime.  ...  The approaches to issues such as directive analysis and communication detection are discussed in detail. The discussion includes fragments of code generated by the compiler.  ...  The library is implemented in C++, and provides a Fortran interface to the compiler. Section 4 gives a avor of the Fortran interface.  ...

Using Coarrays to Parallelize Legacy Fortran Applications: Strategy and Case Study

Hari Radhakrishnan, Damian W. I. Rouson, Karla Morris, Sameer Shende, Stavros C. Kassinos
2015 Scientific Programming  
Scaling behavior was very poor, and profile analysis using TAU showed that the bottleneck in the performance was due to our implementation of a collective, sequential summation procedure.  ...  We anticipate similar results with other compilers once they support the new collective procedures proposed for Fortran 2015.  ...  Acknowledgments The initial code refactoring was performed at the University of Cyprus with funding from the European Com-  ...

2005 Proceedings of the IEEE  
Lower level languages, such as C and Fortran, provide better performance for production applications, but at the cost of tedious programming and optimization by experts.  ...  In this paper, we present our vision and plans for compiler frameworks based on telescoping languages and report on the preliminary research that has established the effectiveness of this approach.  ...  ACKNOWLEDGMENT The authors would like to thank the referees for their numerous constructive suggestions, which substantially increased the quality of this paper.  ...
