PARALLEL SECTIONS

OpenMP* Fortran Compiler Directive: Provides an abbreviated way to specify a parallel region containing a single SECTIONS directive. The semantics are identical to explicitly specifying a PARALLEL directive immediately followed by a SECTIONS directive.

!$OMP PARALLEL SECTIONS [clause[[,] clause] ...]

[!$OMP SECTION]

block

[!$OMP SECTION

block]...

!$OMP END PARALLEL SECTIONS

clause	Can be any of the clauses accepted by the PARALLEL or SECTIONS directives.
block	Is a structured block (section) of statements or constructs. You cannot branch into or out of the block.

The last section ends at the END PARALLEL SECTIONS directive.

Example

In the following example, subroutines XAXIS, YAXIS, and ZAXIS can be executed concurrently:

  !$OMP PARALLEL SECTIONS
  !$OMP SECTION
        CALL XAXIS
  !$OMP SECTION
        CALL YAXIS
  !$OMP SECTION
        CALL ZAXIS
  !$OMP END PARALLEL SECTIONS
