IRPF90: a programming environment for high performance computing

IRPF90 is a Fortran programming environment which helps the development of large Fortran codes. In Fortran programs, the programmer has to focus on the order of the instructions: before using a variable, the programmer has to be sure that it has already been computed in all possible situations. For large codes, it is common source of error. In IRPF90 most of the order of instructions is handled...

Object-oriented C++ boundary element solution of the vector Laplace equation

The Boundary Element Method (BEM) lends itself well to an object-oriented implementation. Well-defined class hierarchies can reduce the size of a problem solution while improving the readability and maintainability of the solution. The BEM uses geometric elements, defined as collections of nodes, to model a surface. Boundary conditions, specified by the problem, are defined at each node. This s...

Computation — Quantum and Otherwise

notion of “computable” — i.e., to isolate the general structure of the computing process itself. The danger we face is that the various types of computability, as defined here, will say more about the individual languages that gave rise to them than they do about this general structure. But anyone who is familiar two or more languages will realize that this difficulty is more one of principle t...

About the Performance of HPF: Improving Runtime on the Cray T3E with Hardware Specific Properties

High Performance Fortran permits to write parallel programs with much less programming effort than by using standard communication libraries such as MPI or PVM. The performance of compiled HPF programs is considered low, though. We show that a compiled HPF application will gain a substantial runtime improvement if compilation incorporates properties of the hardware architecture into the final p...
