Students and classroom educators may qualify for a free version of the suite. Numerical results were identical between the two compilers, and saved me precious time and effort. Our application involves a large number of scientific calculations and computations, and we saw additional performance gains with the Intel Fortran Compiler.
This system uses advanced texture and shape analysis to identify and classify the forest cover species, density, and height in order to produce forest inventory maps. Stereo matching is used to produce 3D digital canopy models that are subsequently analyzed by the texture and shape classification program.
The advantages of Intel Fortran Compiler are:. It is full of very useful tools for developers of complex code who want outstanding application performance.

The optimization reports from the Intel Fortran Compiler are extremely useful and take advantage of the explicit vectorization compiler features as much as possible. Productive stuff for developers from Intel. Keep it coming!
The standards support is also excellent. We have reduced the time needed to analyze a scenario from two months to 12 days by implementing OpenMP with the Intel Fortran Compiler. For more complete information about compiler optimizations, see our Optimization Notice. Absoft Pro Fortan parallelization and optimization options are illustrated by the screen shot of the relevant options page to the right. Absoft Pro Fortran provides five levels of classical optimization and Speed Math options 0 through 9. Parallelization options include auto parallelization as a check box with graphical indications of degrees of success on the source code in the editor pane as highlighting colors.
OpenMP 3. Speed OpenMP is available as none or levels 0 through 5. IMSL 7. Executing programs that use parallelization on machines that do not have Absoft Fortran installed requires inclusion of pthreadVC2. This library is distributed under the LGPL 2.

Installed packages can be selected for inclusion in a build by checkboxes on a tab on the Project Options menu as illustrated in the screen shot to the right. Some of these are detailed below. Absoft offers licenses on all platforms for full versions of GINO or Winteracter that includes bit support, has no limitations, and is integrated with the Absoft Pro Fortran suite. Current releases ship with IMSL 7, the latest release.

Other extensions important for porting from other platforms, such as Cray pointers, are included in Absoft Pro Fortran as part of the compiler. PLplot 5. For all platforms, Absoft Pro Fortran links from user static or dynamic libraries provided by the system, other compilers, or the user. Absoft Pro Fortran has the capability to generate both static and dynamic libraries.
All Absoft compilers can be invoked and fully controlled form the command line. Since Absoft has used the system linker format for all platforms since version Absoft-specific GUI options allow use of programs compiled with Absoft Pro Fortran using the mouse and dealing with pop-ups in the same way that windowed GUI applications are used. The use of Absoft-specific GUI features is portable between platforms using Absoft Pro Fortran on each platform, but other compilers and platforms cannot use these features, and Absoft-specific feature code will not be recognized by other compilers.
The default MRWE program maps input and output to a scrolling window similar to a command prompt, but the user retains all the output and can save it as a text file after the program exits. Hooks are provided in the MRWE GUI program to add Windows system calls to enhance the user interface, providing the potential for a full-featured Windows program written entirely in Fortran.

This Fortran file includes small procedures called during initialization that configure AWE by defining stack size for the interactive window, window size and behavior, and the font. An AWE application can enhance the interactive console window menu items that can be used to execute program units and exit, providing a GUI for an interactive application.
AWE applications distributed for use without the Absoft compiler need to have libgomp. Distribution of executables with these features requires inclusion of QtCore4. Qt   is licensed under the LGPL v. Compiling as an AWE application maps standard input and output to a scrolling window similar to a command prompt, but the user retains all the output and has the option of saving it as a text file after the program exits.
The other features, detailed below, are enabled by the use of an AWE application. An interactive AWE application can be written that does not use the interactive console at all, leaving this window available for use as a run log.
