PGI Compilers and CommandsCompiler or Tool Language or Function CommandPGF77 FORTRAN 77 pgf77PGF95 Fortran 90/95/F2003 pgf95PGFORTRAN PGI Fortran pgfortranPGHPF High Performance Fortran pghpfPGCC C ANSI C99 and K&R C pgccPGC++ ANSI C++ with cfront features pgcpp on WindowspgCC on LinuxPGDBG Source code debugger pgdbgPGPROF Performance profiler pgprofxviiiNoteThe commands pgf95 and pgfortran are equivalent.In general, the designation PGI Fortran is used to refer to The Portland Group’s Fortran 90/95/F2003compiler, and pgfortran is used to refer to the command that invokes the compiler. A similar convention isused for each of the PGI compilers and tools.For simplicity, examples of command-line invocation of the compilers generally reference the pgfortrancommand, and most source code examples are written in Fortran. Usage of the PGF77 compiler, whosefeatures are a subset of PGF95 or PGFORTRAN, is similar. Usage of PGHPF, PGC++, and PGCC is consistentwith PGF95, PGFORTRAN, and PGF77, though there are command-line options and features of these compilersthat do not apply to PGF95, PGFORTRAN, and PGF77, and vice versa.
