  Absoft Pro Fortran Compiler Suites

High Performance Compilers, for Single & Multi-Core Systems


Absoft Fortran represents the highest performing 64-bit compiler available for HPC, Linux, Windows and MacOS environments. Utilizing Cray/SGI technology and advanced optimizations tuned for the individual high performance features of the Advanced Micro Devices AMD64 and Intel Xeon EM64T single and multi-core processors, Absoft assures you of maximum performance with either processor.[Benchmark Comparison]. Fourteen years of product evolution and world-wide testing ensure maximum reliability and robust operation. Absoft compilers support 64-bit or 32-bit code generation, are fully compatible with gnu tool chain or system tools in their respective native environment.


Absoft Fortran includes the industry's only Fortran IDE for simplified code development. The Absoft IDE, designed for Fortran and C includes: Fx3, the leading graphical Fortran/C debugger; programmer's editor; prebuilt math libraries; VAX/Unix libraries; 2D/3D & HDF5 graphics; comprehensive documentation with examples and FREE technical support. The Absoft IDE is bundled with all Pro Fortran products and provides a common feature set and native look and feel across Linux, Windows and MacOS. The MRWE application framework (programmable I/O window) is included on versions for Windows and MacOS. Compare the Absoft feature set with any competitive product.

Key Features
