Fortran 90 Explained

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 Comparison of Bsp Fortran and Distributed Fortran 90

Object-oriented Scientific Programming with Fortran 90

Fortran 90 is a modern language that introduces many important new features beneficial for scientific programming. While the array-syntax notation has received the most attention, we have found that many modern softaware development techniques can be supported by this language, including object-oriented concepts. While Fortran 90 is not a full object-oriented language it can directly support ma...

Interpreting the Performance of HPF / Fortran 90

In this paper we present a novel interpretive approach for accurate and cost-eeective performance prediction in a high performance computing environment , and describe the design of a source-driven HPF/Fortran 90D performance prediction framework based on this approach. The performance prediction framework has been implemented as part of a HPF/Fortran 90D application development environment. A ...
