Ads by Google Related Topics Fortran programming language FORTRAN II FORTRAN IV High Performance FORTRAN      Encyclopedia4U - Fortran - Encyclopedia Article Fortran is mainly used for scientific computing and numerical analysis. Fortran (also FORTRAN) is a programming language originally developed in the 1950s and still in use today. For these reasons, Fortran is not often used outside scientific and engineering numerical analysis, but remains the language of choice for high performance numerical computing. http://www.encyclopedia4u.com/f/fortran-1.html      High Performance Fortran Course High Performance Fortran (HPF) is a programming language for high performance computing applications. The language is a superset of Fortran 90, containing extensions to Fortran 90 to support data parallel programming. The course is being developed by the Manchester and North High Performance Computing Training and Education Centre (MAN-TandEC). http://www.hpctec.mcc.ac.uk/hpctec/courses/HPF/HPFcourse.html      Open Directory - Computers: Programming: Languages: Fortran High Performance Computing Projects - Distributed computing in background, courses, links; at Liverpool University.

We have written a variety of object-oriented plasma particle-in-cell programs on sequential workstations and high performance distributed memory computers in Fortran 90 and C++. While Fortran 90 is not a full object-oriented language it can directly support many of the important concepts of such languages including abstract data types, encapsulation, function overloading, and classes. http://www.cs.rpi.edu/~szymansk/oof90.html      High Performance Fortran in Practice High Performance Fortran (HPF) was defined in 1993 to provide a portable syntax for expressing data-parallel computations in Fortran. Attendees should have some knowledge of FORTRAN 77 (or a similar imperative sequential programming language); a basic knowledge of scientific computation and/or parallelism is also useful, but not essential. The intended audience of this tutorial is researchers and practitioners who are interested in applying data-parallel computation to scientific programs. http://www.cs.rice.edu/~chk/hpf-tutorial.html      The Liverpool High Performance Fortran (HPF) Courses Home Page The University is developing a number of seminars / courses in High Performance Fortran aimed at increasing user awareness of this new de-facto Fortran standard. The course therefore is divided into 10 x 1 hour sessions: Overview, Objects and Expressions, Control Constructs, Arrays, Program Units and Interfaces, Array Arguments, Intrinsics and Modules, Data Parallelism, Alignment and Distribution, Forall and Independent Loops, Procedures and Extrinsics, HPF Library and HPF in the Future. The 75 Minute Seminar An Overview of HPF is an introduction to High Performance Fortran for programmers who are familiar with a high level language such as C, Pascal or Fortran 77. http://www.liv.ac.uk/HPC/HPFpage.html      Southampton - Fortran - Fortran 90 and HPF The High Performance Computing Centre organises training courses and seminars on high performance computing topics. scientific computation using Fortran 90 written by Aleksandar Donev http://www.soton.ac.uk/~fortran/fortran90      Pallas - High Performance Products - Compiler, Language Tools - PGHPF High Performance Fortran It performs global optimization, vectorization, communication optimization, and interprocedural analysis in support of parallelization for the group up to provide code and performance portability as an integrated component of the compilation environment on a wide variety of parallel systems. In today's open multi-platform High Performance Computing environments, pghpf provides a parallel programming solution on which you can standardize. PGI is the undisputed worldwide leader in HPF technology and products for high performance computing (HPC) systems. http://www.pallas.com/e/products/pghpf      High Performance Fortran Somewhat simplified it could be stated that Fortran 90 is efficient on conventional computers and on vector processors, but less efficient on parallel processors. Very important, at the introduction of a new programming language standard, is nowadays that the language should permit efficient compilation and execution not only on conventional computers, but also on parallel and massively parallel systems. Operations for parallel input and output are being considered, and can be found in the Journal of Development. http://www.nsc.liu.se/~boein/f77to90/a8.html      HPF (High Performance Fortran) Promoting Consortium Web page HPF (High Performance Fortran) is a parallel language that is an extension of Fortran. All that users of HPF need do to parallelize their programs is to specify the data layout with some simple directives, and the remaining tasks, communication generation and computation partitioning, are handled automatically by the compiler. The HPF language is defined as a set of directives to be inserted into conventional Fortran programs. http://www.hpfpc.org/index-E.html      High Performance Fortran (HPF) file readme for overview of HPF file hpf-v10-final.ps.gz for HPF Language Specification, Version 1.0, May 3, 1993. , Contains all the technical features proposed for the version, of HPF known as HPF 1.1. file jod-v10-final.ps.gz for HPF Journal of Development, Version 1.0, May 3, 1993. http://www.netlib.org/hpf      High Performance Fortran Forum: Standardizing Parallel Fortran Since its introduction over three decades ago, Fortran has been the language of choice for high-level scientific programming of sequential computers. The HPFF's goal is to develop a set of standard extensions to Fortran that provide the necessary information to support high performance programming on a wide variety of platforms, including massively parallel SIMD and MIMD systems, vector processors, and RISC processors with complex memory hierarchies. Furthermore, the language will be able to express the algorithms needed to achieve high performance on specific architectures in this range. http://nhse.cs.rice.edu/CRPC/newsletters/jan93/news.hpff.html      High Performance Fortran (HPF) Compiler HPF's extrinsic procedures allow you to make calls to existing subroutines written using a message-passing paradigm or other programming styles. In addition to Fortran 90 features, HPF has directives that can be used to optimize performance. The HPF language specification, version 1.0 was published in May 1993, and version 1.1 in November 1994. http://www.ncsa.uiuc.edu/SCD/Hardware/CommonDoc/HPF.html      High Performance Fortran / Fortran 90 Performance is often orders of magnitude worse than well written HPF code. The interconnect network of parallel computers is often much slower than the processors; that is, many computations (sometimes hundreds or thousands) can be performed in the time to send a few bytes of data between processors. The performance of parallel computers is achieved by many processors calculating simultaneously. http://www-ee.eng.hawaii.edu/~mhpcc/hpf      Internet Parallel Computing Archive : Languages : Fortran : Hpf Internet Parallel Computing Archive : Languages : Fortran : Hpf A survey of HPF compilers and HPF environments; restructuring tools; data distribution visualization tools; performance evaluation and measurement tools; debugging tools; runtime systems; task parallelism and HPF and related tools. http://wotug.ukc.ac.uk/parallel/languages/fortran/hpf      HPF on Gilner 346 Cluster High Performance Computing on a Linux PC Beowulf cluster Primary focus is on using High Performance Fortran as a parallel programming language, with the public domain compiler Adaptor and the MPICH MPI implementation as a main parallelizing tool, and the Lahey Intel Linux Express Fortran 95 as the serial node compiler. Although part of our interest in the cluster is this computing power, the main goal of this work is to explore some easy-to-use tools for cluster computing (distributed parallel computing for those more familiar). http://computation.pa.msu.edu/hpf      Citations: High Performance Fortran - Loveman (ResearchIndex) Predicting performance for the class of unstable programs is much more difficult, and is a subject of future work.

The changes included partial conversion from Fortran 77 to Fortran 90, selective unrolling of loops and inlining of procedures, data copies to avoid wavefront (pipelined) communication, along with forward substitutions and loop realignments to avoid the use of privatizable arrays. These results, however, were obtained by almost completely rewriting the benchmark source code as part of the conversion to HPF. http://www.cs.rice.edu/~adve/Papers/SC98.NASBenchmarksStudy/INDEX.HTM      HPF: The High Performance Fortran Home Page The High Performance Fortran Forum (HPFF), a coalition of industry, academic and laboratory representatives, works to define a set of extensions to Fortran 90 known collectively as High Performance Fortran (HPF).
