1.2 Features of the Fortran 95 Compiler

The Sun Studio Fortran 95 compiler provides the following features and extensions:

• Global program checking across routines for consistency of arguments, commons, parameters, and the like.

• Optimized automatic and explicit loop parallelization for multiprocessor systems.

• VAX/VMS Fortran extensions, including:

  • Structures, records, unions, maps

  • Recursion

  OpenMP 2.5 parallelization directives.

• Global, peephole, and potential parallelization optimizations produce high performance applications. Benchmarks show that optimized applications can run significantly faster when compared to unoptimized code.

• Common calling conventions permit routines written in C or C++ to be combined with Fortran programs.

• Support for 64-bit enabled Solaris environments on UltraSPARC and AMD64 platforms.

• Call-by-value using %VAL.

• Compatibility between Fortran 77 and Fortran 95 programs and object binaries.

• Interval Arithmetic programming.

• Some Fortran 2003 features, including Stream I/O.

See Appendix B for details on new and extended features added to the compiler with each software release.
