Book announcement: Scientific Software Design: The Object-Oriented Way
Our colleague Jim Xia recently coauthored a new book: Scientific Software Design: The Object-Oriented Way (ISBN: 978-0521888134). The book is a great example of how to use the object-oriented features of Fortran 2003 in scientific design patterns. BTW, the examples in the book compile with XL Fortran. The Back Cover: This book concerns software design. Although many current discussions of scientific programming focus on scalable performance, this book focuses on scalable design. The authors analyze how the structure of a package determines... [More]

Fine tune your optimization with the new -qassert=contiguous suboption
When the compiler knows that an array occupies a contiguous block of memory, it can perform optimizations based on memory layout. Explicit shape arrays, assumed-size arrays and allocatable arrays occupy contiguous blocks of memory. For array pointers and assumed shape arrays, the compiler cannot determine at compile time if it is the case. In the latest AIX XL Fortran compiler, -qassert=contiguous was introduced to allow the programmer to indicate to the compiler that: * all array pointers are pointer associated with contiguous targets. *...

Introduction to Fortran 2008
Time really flies! About six years ago, the Fortran 2003 standard (commonly abbreviated as F03) was officially published in an attempt to modernize the language. Over the past few years, we've seen a steady increase of interest in adoption of F03 features in the field, particularly the object-oriented programming (OOP) and C interoperability features. F03's C interoperability features struck a chord in the scientific computation community as mixed language applications are becoming the mainstream. In addition, more and more scientific and...
