Module dev.civl.abc

Package dev.civl.abc.ast.node.IF.omp

Interface OmpParallelNode

All Superinterfaces:

ASTNode, BlockItemNode, OmpExecutableNode, OmpNode, StatementNode

public interface OmpParallelNode
extends OmpExecutableNode

This represents an OpenMP parallel pragma. The syntax of a parallel construct is as follows (Section 2.5, OpenMP Specification 4.0.0):

 #pragma omp parallel [clause[ [, ]clause] ...] new-line 
 structured-block
 

where clause is one of the following:

 if(scalar-expression) 
 num_threads(integer-expression) 
 default(shared | none) 
 private(list) 
 firstprivate(list) 
 shared(list)
 copyin(list)
 reduction(redution-identifier :list) 
 proc_bind(master | close | spread)

Method Details

numThreads

ExpressionNode numThreads()

Returns the expression node of num_threads(). NULL if num_threads() is absent.

Returns:

the expression node of num_threads(); NULL if num_threads() is absent.

setNumThreads

void setNumThreads(ExpressionNode value)

Updates the number of threads when the clause num_threads() is present.

Parameters:

value - The expression node representing the argument of the clause num_threads().

ifClause

ExpressionNode ifClause()

Returns the expression node of if(). NULL if if() is absent.

Returns:

the expression node of if(); NULL if if() is absent.

setIfClause

void setIfClause(ExpressionNode value)

Updates the if-condition when the clause if() is present.

Parameters:

value - The expression node representing the argument of the clause if().

isDefaultShared

boolean isDefaultShared()

true iff default(shared), false iff default(none). The default(none) clause requires that each variable that is referenced in the construct, and that does not have a predetermined data-sharing attribute, must have its data-sharing attribute explicitly determined by being listed in a data-sharing attribute clause. By default, default(shared) is assumed.

setDefault

void setDefault(boolean shared)

Updates the default setting when default() clause is present.

Parameters:

shared - The value to be used to update the default setting.
