target simd Construct

| OPENMP API Specification: Version 5.1 November 2020

2.16.20 target simd Construct

Summary The targetsimd construct is a shortcut for specifying a target construct containing a simd construct and no other statements.

Syntax

The syntax of the targetsimd construct is as follows:

 
#pragma omp target simd [clause[ [,] clause] ... ] new-line 
    loop-nest

where loop-nest is a canonical loop nest and clause can be any of the clauses accepted by the target or simd directives with identical meanings and restrictions.

The syntax of the targetsimd construct is as follows:

 
!$omp target simd [clause[ [,] clause] ... ] 
    loop-nest 
[!$omp end target simd]

where loop-nest is a canonical loop nest and clause can be any of the clauses accepted by the target or simd directives with identical meanings and restrictions.

If an end target simd directive is not specified, an end target simd directive is assumed at the end of the loop-nest.

Description The semantics are identical to explicitly specifying a target directive immediately followed by a simd directive.

Restrictions The restrictions for the target and simd constructs apply except for the following explicit modifications:

If any if clause on the directive includes a directive-name-modifier then all if clauses on the directive must include a directive-name-modifier.
At most one if clause without a directive-name-modifier can appear on the directive.
At most one if clause with the target directive-name-modifier can appear on the directive.
At most one if clause with the simd directive-name-modifier can appear on the directive.
