Fortran is the language of choice for scientists and engineers. In addition to its use as a powerful common language for scientific and medical research, it lends itself well to industrial uses in fields such as aeronautics, aerospace, and in military applications. The Fortran language's rich set of mathematical computation features, array manipulation, and flexible constructs help you quickly create complex, efficient modeling algorithms.
Leon Kiriliuk, Igor Todorovski, and Nancy Wang explain how they save processing and load time by using PHP and cURL to cache dynamic web pages on the server. Their method caches session variables, as well as the HTML. More >

- Handling TOC overflow on IBM AIX systems
When too many addresses of global symbols in C, C++, and Fortran programs are stored in the table of contents, TOC overflow occurs. Learn the different mechanisms for handling it, the performance impact of each, and the best ways to use the mechanisms, based on the application characteristics.

- A compiler option that helps debug optimized code
Debugging optimized code has always been a challenging task, because it could make the program state not available to debuggers. Daniel Chen and Tommy Hoffner introduce a compiler option that helps debug optimized IBM XL C/C++ and XL Fortran code.
- New technique uses XL C/C++ and Fortran compilers in regression testing
The authors introduce a test selection technique to reduce the number of test cases used for regression testing without degrading test coverage. It uses profile data from the function tracing feature of the XL C/C++ and Fortran compilers to select a minimized and accurate subset of test cases.
