Since the development of FORTRAN fifteen years ago we have observed a steady growth in the development of that part of computer science that deals with programming. In particular, there has been an outstanding development in programming languages: we can say more—and in a more natural fashion—to the computer and its attendant service programs to get our tasks accomplished. Our programming langu...

in the present study, computational fluid dynamics (cfd) techniques and artificial neural networks (ann) are used to predict the pressure drop value (δp ) of al2o3-water nanofluid in flat tubes. δp  is predicted taking into account five input variables: tube flattening (h), inlet volumetric flow rate (qi  ), wall heat flux (qnw  ), nanoparticle volume fraction (φ) and nanoparticle diameter (dp ...

This paper presents an environment for programming distributed memory computers using a language such as High Performance Fortran. Emphasis is put on compilation techniques for parallel loops and on the associated runtime support. A multi-threads scheme has been deened and implemented in order to eeciently overlap the communication and the computation phases. Un ex ecutif utilisant les processu...

Ever-increasing size and complexity of software applications and libraries in parallel scientific computing is making implementation in the programming languages traditional for this field—FORTRAN 77 and C—impractical. The major impediment to the progression to a higher-level language such as C++ is attaining FORTRAN 77 or C performance, which is considered absolutely necessary by many practiti...

Using the Message Passing Interface (MPI) in C++ has been difficult to this point because of the lack of suitable C++ bindings and C++ class libraries. The existing MPI standard provides language bindings only for C and Fortran 77, precluding their direct use in object oriented programming. Even the proposed C++ bindings in MPI-2 are at a fairly low-level and are not directly suitable for objec...

Since the introduction of the Java programming language, there has been widespread interest in the use of Java for high performance scientific computing. One major impediment to such use is the performance penalty paid relative to Fortran. Although Java implementations have made great strides, they still fall short on programs that use the full power of Java’s object-oriented features. In this ...

Chapel is a high-level parallel programming language that implements a partitioned global address space model (PGAS). Programs written in this programming model have traditionally been selfcontained entities written entirely in one language. While this approach enables the compiler to produce better performing code by doing whole program optimization, it also carries a risk of positioning PGAS ...

This Paper describes the research centered on the Charm Parallel Programming System. Charm is a portable parallel programming system under development at the University of Illinois for the past six years. The system enhances latency tolerance via message driven execution, supports dynamic load balancing for medium grain tasks, and provides innovative language features such as speciically shared...

A multitude of problem-oriented programming languages are being created in order to facilitate programming in various fields.Th~se languages have two advantages for non-programmers who need a computer for solving their problems: I. they are not forced to spend much time on learning a complicated machine language; 2. they do not necessarily have to alter their programs when they are obliged to u...
