PGF77 Workstation

by The Portland Group

FORTRAN 77 for 32-bit and 64-bit AMD64 and IA32 processor-based systems.

If you develop or maintain scientific and technical applications, chances are you have a big investment in Fortran. After four decades, it's still the cornerstone of technical computing. PGF77® Workstation, The Portland Group's native OpenMP-parallel optimizing FORTRAN 77 compiler and Linux OpenMP and MPI parallel debugger/profiler for Intel Pentium II/III/4, Intel Xeon/Xeon-64 and AMD Athlon/AthlonXP/Opteron processor-based 32-bit and 64-bit Linux and 32-bit Windows (NT/2000/XP) workstations, provides the features, quality, and reliability you demand for development and maintenance of advanced scientific and technical applications. Support for common IBM, DEC, and Sun extensions, Cray compatibility, and integrated cpp pre-processing allow you to migrate legacy F77 applications quickly and easily from RISC workstations and servers to 32-bit and 64-bit systems. PGI's outstanding performance allows you to build high performance parallel F77 applications for single, dual, or quad-processor workstations.
