  • A Parallel time-domain Maxwell solver using upwind schemes and triangular meshes
    1993
    Co-Authors: Jean-pierre Cioni, Loula Fezoui, Hervé Steve
    Abstract:

    A finite-volume/finite-element method developped in CFD is applied to solve numerically the time-dependent 2D Maxwell system. We use a third-order accurate explicit scheme with triangular meshes. We are particularly concerned here with scattering problems for both homogeneous and non-homogeneous materials. Radar cross section calculations are presented and compared with exact or integral method solutions. A parallel Version of the algorithm on the connection machine is presented and the performances are compared with those obtained with a fully Vectorized Version on the Cray YMP.

  • pair potential calculation of molecular associations a Vectorized Version
    Computer Physics Communications, 1991
    Co-Authors: Francisco Torrens, Enrique Orti, J Sanchezmarin
    Abstract:

    Abstract The program AMYRVF is a Vectorized and largely modified Version of a previous program called AMYR for calculating molecular associations by means of Fraga's pair-wise atom-atom potential. Three new minimization procedures have been implemented as well as other improvements such as the inclusion of new pair-wise dispersion energy terms with damping functions, and the calculation of topological indices. Benchmark tests have been carried out on an IBM 3090 150E VF; the timings for the new vector algorithms and for the standard scalar computations, as well as the dependence of the overall performance gain on the size of interacting systems are reported for the VS Fortran 2.4 compiler enhanced by the ESSL Vectorized library. The new program vectorizes 97% of the computation.
