P 3 T is an interactive performance estimator that assists users in performance tuning of scientiic Fortran programs. It detects performance bottlenecks in the program, identiies the causes of performance problems, and guides the user in selecting eeective program transformations in order to gain performance. Four of the most critical performance aspects of parallel programs are estimated: load...

We describe a Fortran 90 program to calculate population ratios of atomic levels. The program solves the equations of statistical equilibrium considering all possible bound-bound processes: spontaneous, collisional or radiation induced (the later either directly or by fluorescence). There is no limit on the number of levels or in the number of processes that may be taken into account. The progr...

The application of Heuristic Search Methods for the earthquake resistant design of structural frames is discussed. The Tabu Search method was selected for application to structural weight optimization of steel moment frame structures. A computer program was developed that uses Tabu Search for weight minimization of two-dimensional framed structures. Written in the FORTRAN computer language, the...

PVM is a succesfull programming environment for distribu ted computing in the languages C and Fortran Recently several imple mentations of PVM for Java have been added making PVM program ming accessible to the Java community With PVM for Java however the user still needs to partition the prob lem calculate the data partitioning and program the message passing and synchronization In this paper J...

Algorithm Templates. According to Kant and Steinberg [82], linear solvers and related algorithms can be cast in the form of so-called algorithm templates. Templates are algebraic structures that capture the essentials of an algorithm, elaborated with problem-specific aspects, and can be transformed into a chosen target language. The SciNapse system [2] uses algorithm templates in the automatic ...

We present two methods for expressing computations based on recurrence relations and discuss their relative merits. One method, the structural blanks approach, is built on top of traditional programming languages like Fortran or Pascal. It aims at program reuse and bases a certain architecture of software packages. The other method, the constructive recursive approach, is based on recursive rel...

To calculate the upper limit for the Poisson observable at given confidence level with inclusion of systematic uncertainties in background expectation and signal efficiency, formulations have been established along the line of Bayesian approach. A FORTRAN program, BPULE, has been developed to implement the upper limit calculation.

The implementation of the Profile Interchange Format (PIF) for Technology CAD (TCAD) purposes is demonstrated. An application program interface for use with process and device simulation tools coded in FORTRAN, C and LISP is presented, capable of performing convenient, fast and flexible access to an extendable binary data format which fulfills todays and future needs for physical and logical TC...
