Highest reliability - Absoft's long-standing reliability is based on a mature code base - our Cray Research-based Fortran front-end is the most commercially weathered and reliable Fortran compiler front-end in the industry.

Fully source compatible - Absoft is the only commercial Fortran vendor offering a common Fortran solution across Linux, Windows and OS X with superior performance on both AMD and Intel processors. Absoft Fortran is fully compatible with existing Absoft Fortran compilers and the GNU tool chain, so existing Absoft customers need only to recompile their application to take advantage of significant additional performance.

Live, industry-leading technical support - Absoft has the reputation of the best Fortran technical support in the industry and is the best choice for a single point of contact for customers to receive top quality support.

Lowest price - Not only do our new, lower prices give you the best price/performance available, Absoft offers the only Fortran compilers with MaxFlex licensing which allows licenses to be reused freely across different platforms (Linux, Windows, OS X) from a single license server. These features represent significant cost savings for developers working in environments where computers and compilers need to be shared across multiple systems.

Absoft's Fortran Compiler for Linux is unrivaled in both ease of use and its comprehensive list of features and typically generates code that performs as fast or faster than any other Fortran compiler. Absoft compilers conform to all DoD MIL-STD 1753, FIPS 69-1, and POSIX standards, support most popular VAX/VMS extensions including RECORD, STRUCTURE, POINTER, and UNION, (per V5.4 of VMS FORTRAN), QUAD data types as well as others from IBM/VS, Cray, Sun FORTRAN and FORTRAN 66 conventions. PIC code, automatic byte swapping, full integration with GNU tools and LSB compliance means porting code from any environment with Absoft requires little more than a recompilation. The easy-to-use Absoft Fortran compiler "just installs". A 2D/3D pre-compiled graphics library, pre-built BLAS, ATLAS and LAPACK90 libraries and technical support from friendly engineers is included at no additional charge.

Absoft is the only Fortran vendor offering bundle pricing on source-compatible Fortran solutions for all of today's popular computing platforms (Windows, Macintosh, and Linux). Customers save time and money with source-compatible Fortran solutions for all their development environments.

Options for an automatically parallelizing pre-processor, OpenMP and cluster configurations will be available. Technical support, service packs and software fixes are included with each license purchased at no additional charge. See www.polyhedron.com for recent benchmark comparisons of this compiler's superior Fortran 90 and Fortran 77 performance against other Fortran compilers.

Superior Performance

New Absoft Fortran Compilers for Linux use state-of-the-art optimization technology to deliver superior execution speed and the best real-world application performance on x64 AMD® Opteron and Intel® Xeon™ processors based on Linux systems. For developing Fortran in parallel environments, tools that can automatically restructure serial code for dual processors, add OpenMP directives or help build and debug complex code on a distributed cluster system are optionally available.

Ease of Use

The Absoft Fortran Compiler for Linux will install on any popular Linux distribution. Fortran includes a complete User Guide (.PDF) with clear examples of editing, compiling, debugging and running programs. To ensure customers obtain maximum performance, options are suggested for optimizations and compatibility. Linking with C/C++ is simple and the Absoft Fx2 Debugger included with this compiler is one of the only debugging solutions that can properly debug both Fortran and C/C++ programs. Pre-built math and graphics libraries are also included.

Compatibility

Absoft Fortran adheres to the latest ISO and ANSI Fortran 95 standards, and generates best-of-class performance for 32-bit and 64-bit AMD and Intel processors. The compiler is fully source-compatible with all previous and future versions of Absoft Fortran Compilers. Huge productivity gains can be attained by merely recompiling existing source code. For legacy applications, Absoft compilers support:

Multi-platform

One solution across Linux, Windows and Mac OS. Absoft compilers are fully source compatible across all popular platforms and a simple recompile is typically all that is required to move from one environment to the next. Absoft offers dynamic license management options which can instantly change to support the platform you are currently working on.

Absoft Fortran compilers also comes with several advanced features from the latest Fortran 2003 language specification which include:

Was neu ist

Up to 40% faster code on 64-bit Opteron and Xeon than v9. All that is necessary in most cases to increase the performance of your application is to recompile your code. New flexible configurations include the Fortran Express license on a 12 month subscription basis for cost sensitive, short term, or academic projects, Express Plus license with perpetual licenses and Absoft Standard with single user and floating perpetual licenses available. Further, Absoft's no charge companion home license policy allows registered users to install Absoft Fortran compilers on their personal computer at no additional charge.

Neu in v10.2:

New Compiler Features:

• SSE4 support for AMD and Intel - AMD SSE4a and Intel SSE4.1 vector instructions are different but Absoft Pro Fortran v10.2 supports both. Automatically detection establishes your processor type and sets SSE accordingly. Internal tests have show up to 10% speed increase using SSE4.
• New parallel make facility can substantially decrease the build time for large projects. This feature takes advantage of multi-core architectures by compiling two or more independent program units simultaneously. The parallel make system is Fortran 90 module aware and automatically handles the additional dependencies created by module use.
• Source Browsing for indexed C/C++ and Fortran elements
• Code Completion & Text Overwrite Mode - Speeds code development
• Dual Screen Editing - Display 2 different screens simultaneously. Drag and drop code between screens, and/or edit each independently.
• External Makefiles for Projects - Use and edit existing Absoft and non-Absoft makefies
• Project wide search and replace feature - Simplifies code edits
• Bracket and Paren Matching - Cut down on coding errors
• C-style commenting added - Commenting for C, C++ and Fortran now supported
• Exception traceback - Added to Absoft Pro Fortran v10.2 for Linux

Fortran IDE Designed by Fortran Experts:

• Fortran IDE included at no additional charge!
• Designed specifically for Fortran/C development it provides both graphical and command line interfaces for compiler and debugger
• Supports select third party products as plug-ins in addition to Absoft tools
• Same functionality on Linux, Windows and Mac - one learning curve for all systems

Multi-processing Capabilities

Symmetric Multi-processing (SMP)
For Fortran compiler users with multi-processor systems, the optional VAST-F/Parallel package is a pre-processor that can restructure serial programs to automatically add parallelism to Fortran programs to enable faster execution on machines with multiple processors. The original Fortran source code is unaffected. VAST-F/P is an easy and cost effective way to reap the performance benefits offered by multi-processor environments with Absoft's Fortran compilers.
