Absoft Fortran for Linux

  Absoft Pro Fortran Compiler Suite For
x86 or x86_64 Linux

The Only Fortran Available That Delivers Everything Developers Need
In A Single Integrated Package for 32-bit or 64-bit systems

 

NEW! Pro Fortran v11 includes integrated OpenMP support. Not only does v11.0 provide OpenMP support in the compiler and runtime, but the upgraded Absoft Fx3 graphical debugger supports debugging multi-threaded OpenMP Fortran sessions, and the IDE adds new features which allow you to control the OpenMP environment. Combined with Absof'ts superior code generation and Windows 7 compatibility, Pro Fortran provides the easiest and most complete solution for building multi-threaded OpenMP applications.

Absoft compilers automate building parallel code
on multi-core systems. Auto-parallelization and vectorization ensures maximum application performance. A new scheduler improves performance in 32-bit environments and SSE 4*/4.2 maximizes performance on the latest x64 AMD Shanghai and Intel Nehalem processors. Examples of using auto-parallelization and improving performance with OpenMP are included in the documentation. Scalapack and BLACS libraries are included for enhanced MPI support.

Includes the only Fortran IDE designed by Fortran experts. Absoft simplifies code development by solving the problems associated with IDEs such as Visual Studio and Xcode - excellent for C++, but with no knowledge of Fortran. The Absoft Fortran IDE supports both Fortran and C and automatically provides proper syntax sensitivity, array indexing, etc. for each language. It includes everything you need: F95 Fortran compilers, programmer's editor, Fx3 graphical debugger, application framework, graphics and optimized math libraries in a single, easy-to-use package.

Single Solution - Linux, Windows and MacOS. Simplify code development for multiple platforms. Absoft provides same look and feel on every platform and allows you to build native applications for Linux, Windows and Mac from a single code base! Absoft's exclusive MaxFlex license manager allows a single license to float across Linux/Windows/Mac, saving you time and money.

Compatibility and Companion Products:

Absoft uses an extended version of the Cray CF90 front end and adheres to the latest ISO and ANSI Fortran 95 standards. Extensions from all major workstations have been added to make sure your code ports from any environment with minimal effort.

Absoft Fortran 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 (REAL*16) data types as well as others from IBM/VS, Cray, Sun FORTRAN as well as FORTRAN 66 conventions.

Automatic byte-swapping and full integration with many third party tools means porting code from virtually any environment requires little more than a recompilation without rewriting code. The F95 compiler can operate in F95, F90 or F77 modes.

• IMSL Fortran Numerical Library available for 32-bit and/or 64-bit Linux.
• MATFOR Numerical and Visualization Libraries
  available for 32-bit and/or 64-bit Linux.
• VAST-F/Parallel Pre-processor that automatically parallelizes source code.
   
• STAR-CD - currently requires Absoft Pro Fortran v8.2 or v9 depending on your STAR-CD version.
   

Absoft Fortran fully supports automatic multi-threading of applications but VAST-F/Parallel is required for OpenMP support.

VAST-F/Parallel when used in conjunction with Absoft Fortran provides further optimizations and auto-parallelization opportunities, which may result in improved application performance.

Easy to Use:

'Just Installs' without modification on the latest 64-bit Linux implementations from Red Hat, SuSE, Mandrake, and other major builds and includes a complete User Guide with clear examples of editing, compiling, debugging and running programs.

Powerful and ease-to-use, the next generation Absoft Graphical IDE, and the Absoft Fx3 Debugger included with this compiler know if you are using C or Fortran and adjust key words, array indexing, etc. accordingly. Building and debugging mixed Fortran/C applications is easy.
 

Graphics Libraries

Includes 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.

Multiple graphs (of the same or different sizes) may be placed on a single page with multiple lines in each graph. Output can be to your monitor, a file, a printer or in postscript format.

There are almost 2000 characters in the extended character set including four different fonts, the Greek alphabet and a host of mathematical, musical and other symbols. PLplot is included on all versions of Pro Fortran and is source compatible across Linux, Windows and Mac platforms. HDF precompiled libraries are included with every copy of Pro Fortran.
 

Multi-Platform Capabilities

Absoft manufactures high performance Fortran compiler suites for Windows, Macintosh(Intel & PPC), Intel/AMD Linux and PPC/Linux based systems.

Absoft compiler suites are source compatible across the different platforms which means that in most cases, only a recompile is needed to port code from one environment to another.
