F.2 Parallel Library Routines (TU*X only)

Compaq Fortran provides library routines you can use for directed parallel decomposition (when specifying the -mp and -omp compiler options) on Tru64 UNIX systems:

• Routines using the OpenMP Fortran API format (Section F.2.1)
  
  
• Equivalent routines using a format compatible with existing programs (Section F.2.2)

When writing new programs that call the run-time parallel library routines, use the OpenMP Fortran API format.

For a helpful program interface, you should add the following statement to the program unit containing the parallel routines:

  INCLUDE '/usr/include/forompdef.f'

For more information on a specific routine, see the appropriate reference page; for example, for more information on omp_set_lock, see omp_set_lock(3f).

• On parallel routines, see your user manual.
  
  
• On parallel directives, see Section 15.2.
