FORTRAN 90 — A SUMMARY

QCDF 90 : Lattice QCD with Fortran 90 ?

We have used Fortran 90 to implement lattice QCD. We have designed a set of machine independent modules that define fields (gauge, fermions, scalars, etc...) and overloaded operators for all possible operations between fields, matrices and numbers. With these modules it is very simple to write high-level efficient programs for QCD simulations. To increase performances our modules also implement...

Scalarizing Fortran 90 Array Syntax

Array syntax, existed in many languages, adds expressive power by allowing operations on and assignments to the array sections. When compiling to a uniprocessor machine, the array statement must be converted into a loop that maintains the correct semantics, by a process called scalarization. Scalarization presents a significant technical problem because an array assignment needs to be implement...

A Fortran 90 Separable Hamiltonian System Solver

We discuss a prototype Fortran 90 separable Hamiltonian system solver and present a template illustrating its use. The solver permits a wide choice of symplectic and non-symplectic integrators, and xed and error-controlled integration step sizes. It is designed to permit insertion of new formulas as they become available.
