The most common parallelization strategy for many Computational Mechanics (typified by Computational Fluid Dynamics(CFD) applications) which use structured grids, involves the one directional partition based upon slads of grids. For parallelised versions of CFD codes to scale well we must employ two (or more) dimensional partitions. However, FORTRAN code implementations by multi-directional par...

This paper introduces an analytical model that enables automatic estimation of the cache performance for both sequential and data parallel Fortran programs. The estimation is based on a classiication of array accesses with respect to cache reuse at the source code level. An estimated upper bound of the number of distinct cache lines accessed inside of a loop is statically computed. Based on thi...

We present three versions of the revised spectral test for the analysis of liner congruential random number generators. One is a Fortran 90 version of the code presented in 6] which extends the range of integer arithmetic operations by performing the arithmetic using oating-point numbers. The range of modulus values which may be analyzed is determined by the length of the mantissa. The other tw...

A modular and efficient version of PC program for calculating ligand-field parameters, i.e. crystal-field model (CFM) and angular overlap model (AOM) is presented. The LFP program is designed to calculate the ligand-field parameters of low symmetry transition metal complexes. It is based on the general method for the analysis of central ion states distortion using group theory. The program has ...

A different view on software complexity based on long range correlation is presented in this paper. Four different methods are first proposed and then used in the analysis of twenty FORTRAN programs. All methods being used indicate the presence of long range correlations, but every method gives different results. The presence of long range correlations denotes that we can in fact regard the com...

Computations with higher than the IEEE 754 standard double-precision (about 16 significant digits) are required recently. Although there are available software routines in Fortran and C for high-precision computation, users are required to implement such routines in their own computers with detailed knowledges about them. We have constructed an user-friendly online system for octupleprecision c...

Distributed-memory systems (DMMPs) are powerful tools for solving large-scale sci-entiic and engineering problems. However, these machines are diicult to program since the data must be distributed across the processors and message-passing operations must be inserted for communicating non-local data. In this paper, we discuss the automatic parallelization of Fortran programs for DMMPs, based on ...
