Key Benefits

Superior Performance

V9.0's new optimization technology for both scalar SSE2 and x87 delivers superior real-world application performance on AMD Athlon, Pentium4 and Xeon family processors. For developing Fortran in parallel environments, tools which 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 Fortran 95 compiler for 32-bit Linux will install on any popular Linux distribution with any build of glibc. Fortran 95 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 few debugging solutions which can properly debug both Fortran and C/C++ programs. Pre-built math and graphics libraries are also included.

Compatibility

Absoft Fortran 95 uses an extended version of the Cray CF90 compiler technology and adheres to the latest ISO and ANSI Fortran 95 standards. 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 data types several from IBM/VS, Cray, Sun FORTRAN and FORTRAN 66 conventions. Automatic byte swapping and full integration with GNU tools means porting code from any environment often requires little more than a recompilation. The Absoft F95 compiler can operate in F95, F90 or F77 mode.

Key Features

• Industry leading performance and optimizations
