Absoft Pro Fortran Compiler Suites
General Overview

High Performance Compilers, for Single & Multi-Core Systems

Absoft #1 on AMD Multi-Core cpus!


Pro Fortran 2014 - Builds Faster Code, Faster with Absoft's Exclusive Dynamic AP Load Balancing Technology, AVX support, OpenMP 3.0 support, SMP Analyzer, Tools Plug-in, New HPC Scientific & Engineering Math Library, GPU options and more!

Absoft's Pro Fortran 2014 tool suite automates building extremely fast parallel code on AMD and Intel multi-core systems. Compiler features include: APO, IPO, PGFDO optimizers, and Absoft's exclusive Dynamic AP load balancing technology which can increase performance up to 20% on multi-core systems. Pro Fortran v2014 has AVX support, Absoft Window Environment (AWE), External Libraries and Tools Plug-in, expanded F2003 support and enhanced Fx3 graphical debugger. CUDA GPU support via nVidia's CUDA libraries or HMPP preprocessor. IMSL v7.0 numerical libraries are an available option.

The Absoft IDE is the only commercial Fortran/C++ development environment designed by Fortran experts. It includes: programmer's editor, Absoft's SMP and Vector analyzer, Fx3 graphical debugger, SMP and MPI control features, optimized math libraries and 2D/3D graphics.

All Pro Fortran products include premier technical support directly from Absoft, Quick Fixes and Service Packs. IMSL's highly optimized numerical and statistical libraries (1000+ routines) are a low cost bundle option. Pro Fortran is compatible with recent releases of Fedora Core, openSuse, Ubuntu, RedHat Enterprise Linux and CentOS. Pro Fortran is a complete solution, nothing else to buy or learn - AND it generates 20% faster code!

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.

Mixed Fortran/C Development

Absoft Fortran is designed to be fully compatible with the implementation of the Standard C Programming Language. 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...

"I have been quite pleased with the performance of the Absoft Pro Fortran compiler and associated tools.

Working with the Absoft tools on an Intel based system has been a pleasure, especially considering the speed of compilation and execution of my resulting programs!"
