Graphics Programming
The AWE Fortran application framework provides Fast Data Visualization to easily create a variety of plots and charts and also supports the AWE Canvas with graphics primitives such as lines, curves, and rectangles. OpenGL graphics programming is supported through included f90gl and f03gl interface packages. The Absoft Linux Pro Fortran package also contains pre-built versions of a flexible graphics library called PLplot. PLplot can be called from Fortran as well as C/C++ and can create standard x-y plots, semilog plots, log-log plots, contour plots, 3D plots, mesh plots, bar charts, and pie charts.
OpenMP 3.1 Support
Absoft Pro Fortran provides complete Open MP 3.1 support in the compiler and debugger.
GNU GCC C/C++ Compiler Support
The AbsoftTools integrated development supports mixed language programming by integrating the GNU C/C++ compilers included as a standard part of Linux distributions.
System Requirements
- A computer with a 32 or 64 bit Intel or AMD processor supporting the Intel SSE2 instruction set (Intel Pentium 4 or later, AMD Athlon II or later). For best performance, a multi-core or multi-processor system is recommended.
- 2GB RAM
- 4GB free disk space
- A 32 or 64 bit Linux OS distribution
- RedHat 6.x, 7.x,8.x
- CentOS 6.x,7.x.8.x
- SuSE
- Ubuntu
- Debian
- Most other distributions

Technical Support
Absoft branded products include Premier Technical Support and Initial Software Maintenance at no additional charge from the time of purchase for as long as the purchased version remains the current release version.
Initial Software Maintenance (ISM) includes free electronic downloads of all interim Service Packs and Quick Fixes from Absoft. Version upgrades require a separate purchase but at discounted prices for commercial/government users – Academic users already receive the lowest available price when making an academic purchase.
For further information on available support for current, registered users, see the support section on this site.
Continuing Software Maintenance
At the conclusion of the Initial Software Maintenance term (i.e. when a new version of the purchased product is released) customers may either purchase a Product Upgrade or within 30 days of the new product release, purchase Continuing Software Maintenance for an additional 12-month maintenance term.
Continuing Software Maintenance (CSM) includes all elements of Premier Technical support plus all Product Upgrades issued during the 12-month Continuing Software Maintenance term. Annual renewals of Software Maintenance will be made available at a low-cost to commercial/government customers who renew within their unexpired Maintenance term – Academic users already receive the lowest available price when making an academic purchase.
For users electing not to renew Continuing Software Maintenance and having expired maintenance terms but later wishing to rejoin CSM, Reinstatement Software Maintenance (RSM) terms may be purchased.
