This paper describes automatic coarse grain parallel processing on a shared memory multiprocessor system using a newly developed OpenMP backend of OSCAR multigrain parallelizing compiler for from single chip multiprocessor to a high performance multiprocessor and a heterogeneous supercomputer cluster. OSCAR multigrain parallelizing compiler exploits coarse grain task parallelism and near ne gra...

The majority of the SECS program has been converted to the VAX in Fortran and is operational. A graphic driver for the Evans & Sutherland PS330 display system has been also added. New chemical transforms in heterocyclic chemistry have been written and debugged. Through our collaborations in Japan 1000 new chemical transforms have been added using an automatic ALCHEM transform writing program. A...

In this paper a Monte Carlo generator, GaGaRes, is presented which can be used to describe two-photon resonance production in e+e− collisions. The program can generate the five lowest-lying C=+1 meson states of any qq̄ combination together with the outgoing electron and positron. The dependence on the photon virtualities Q1 and Q 2 2 is fully taken into account. The program also generates the de...

This paper presents a comparative study to evaluate and compare Fortran with the two most popular programming languages Java and C++. Fortran has gone through major and minor extensions in the years 2003 and 2008. (1) How much have these extensions made Fortran comparable to Java and C++? (2) What are the differences and similarities, in supporting features like: Templates, object constructors ...

HAMILTON is a computer code performing all algebraic operations necessary for an analytic determination of the power series of the Hamiltonian equations of motion in the electromagnetic fields with at least one plane of symmetry . It is written entirely in FORTRAN in order to achieve fast machine performance, a requirement which is essential due to the complexity of the equations of motion in h...

We describe algorithm MINRES-QLP and its FORTRAN 90 implementation for solving symmetric or Hermitian linear systems or least-squares problems. If the system is singular, MINRES-QLP computes the unique minimum-length solution (also known as the pseudoinverse solution), which generally eludes MINRES. In all cases, it overcomes a potential instability in the original MINRES algorithm. A positive-...
