Watch your language!

Sure, object orientation is unnatural-computer programming in any language is. We must rely on good principles, good tools, and good languages. This author tells L. Hatton to blame C++ and its culture for the bad rap against OO, and to look elsewhere for a workable OO language. He suggests comparing C to a better OOP language. In his view, Eiffel fosters a culture embodying the best tendencies of OOP Most importantly, Eiffel offers programmers the ability to specify formally, at the implementation level, the behavior of a class. Several companies have reported that such specifications, written in Eiffel, can greatly improve the reliability of large scale software systems

Finite element programming and C

In finite element programming, data have to be dealt with which are of different types but belong together in a logical sense. It would be very effective, with respect to program readability and maintainability, to store these data as a single unit. Effcient software design requires that all parts of information, which belong together logically, are stored as a single data unit. This can be accomplished utilizing structured data types.

Dynamic memory allocation allows the definition of dynamic variables which can be created and destroyed during run-time. Dynamic memory management is handled in C by pointers. In other conventional languages, e.g. Fortran 77, the programmer has the responsibility to select adequate array sizes for the largest problem to be solved. This often leads in engineering practice to array oversizing and to memory wasting. By allocating memory dynamically during program execution according to actual problem size, wasting can be avoided.

The combination of structured data and pointers along with the dynamic memory allocation capabilities of C allows the creation of linked lists. Utilizing these concepts, an effective and easy-to-read C program has been written for finite element analysis. The C program presented demonstrates the use of these techniques for interactive finite mesh generation. The strengths of C are compared to that of Fortran 77 and Fortran 90. It has been found that for finite element programming C is in many aspects superior to Fortran 77. However, it has some disadvantages in comparison with Fortran 90 concerning array processing.     

Object-Oriented Programming in Modern Fortran

Parallelism in object-oriented languages: a survey

Fourteen concurrent object-oriented languages are compared in terms of how they deal with communication, synchronization, process management, inheritance, and implementation trade-offs. The ways in which they divide responsibility between the programmer, the compiler, and the operating system are also investigated. It is found that current object-oriented languages that have concurrency features are often compromised in important areas, including inheritance capability, efficiency, ease of use, and degree of parallel activity. Frequently, this is because the concurrency features were added after the language was designed. The languages discussed are Actors, Abd/1, Abd/R, Argus, COOL, Concurrent Smalltalk, Eiffel, Emerald, ES-Kit C++, Hybrid, Nexus, Parmacs, POOL-T, and Presto

Programming language features,usage patterns,and the efficiency of generated adjoint code

The computation of gradients via the reverse mode of algorithmic differentiation is a valuable technique in modelling many science and engineering applications. This technique is particularly efficient when implemented as a source transformation, as it may use static data-flow analysis. However, some features of the major programming languages are detrimental to the efficiency of the transformed source code. This paper provides an overview of the most common problem scenarios and estimates the cost overhead incurred by using the respective language feature or employing certain common patterns. An understanding of these topics is crucial for the efficiency or even feasibility of adjoint computations, particularly for large-scale numerical simulations, for example, in geosciences. While one cannot hope to cover all effects observable with a given programming language in a given run time environment, the paper aims at providing a reasonable guide for the users of C/C++ and Fortran source transformation tools for algorithmic differentiation.
