PARALLEL SECTIONS

インテル® Fortran コンパイラー 14.0 ユーザー・リファレンス・ガイド

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.

例

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
