Fortran Compiler Suites & Tools for Windows Mac and Linux Programmers & Software Developers!



Absoft Pro Fortran Compiler Suites General Overview High Performance Compilers, for Single & Multi-Core Systems *Absoft #1 on AMD and Intel Core-i7 Multi-Core cpus!*
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. OpenMP, auto-parallelization, auto-vectorization and twenty-five 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.

Multi-Processor Capabilities Absoft Pro Fortran uses all available processors by default. Multi-threading, vectorization, a high performance parallel optimizer, data perfecting, profile guided optimization, IPO, and advanced optimizations can be performed automatically. Combined with the included math libraries, Absoft provides the best solution for creating maximum application performance on single and multi-core systems. OpenMP Support Absoft Fortran fully supports automatic multi-threading of applications. Absoft Pro Fortran (v11 and above) includes integrated OpenMP support in the compiler and the Absoft Fx3 graphical debugger debugs OpenMP Fortran sessions.

The linker can be used freely to link C modules with Fortran main programs and vice versa. However, some precautions must be taken to ensure proper interfacing. Data types in arguments and results must be equivalent. The case of global symbols in C is significant. The symbolic names of external procedure must match in case. More details...
