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.
Cluster Kits (Distributed Multi-processing or DMP Systems)
Software cluster kits built using Absoft Fortran 95 compiler for Linux are available for cluster users. These kits include the complete Fortran 95 compiler, the Fx2 multi-language debugger, select guides on running clusters, and pre-built versions of popular cluster software.

Absoft Fortran 95 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.
Optional multi-processing tools include automatic parallelization tools, and an OpenMP pre-processor for symmetric multi-processing (SMP). Automatic parallelization tools can automatically restructure programs with serial code to programs taking advantage of the high performance computing capabilities of multi-processor systems (see VAST-F/Parallel). Cluster Software Kits are available for users building cluster systems. A version of Fortran 95 with a complete integrated development environment (IDE) is planned for the Windows environment.
Third party products, and graphics packages are also available for Absoft's Fortran 95 compiler for AMD 64-bit Linux platforms.
