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