NAME¶

TAU_MAPPING_OBJECT - Declares a mapping object

SYNOPSIS¶

C/C++:

TAU_MAPPING_OBJECT(FunctionInfo FuncIdVar);

DESCRIPTION¶

To create storage for an identifier associated with a higher level statement that is mapped using TAU_MAPPING, we use the TAU_MAPPING_OBJECT macro. For example, in the TAU_MAPPING example, the array expressions are created into objects of a class ExpressionKernel, and each statement is an object that is an instance of this class. To embed the identity of the statement we store the mapping object in a data field in this class. This is shown below:

EXAMPLE¶

C/C++ :

template<class LHS,class Op,class RHS,class EvalTag>
class ExpressionKernel : public Pooma::Iterate_t {


  public:


      


    typedef ExpressionKernel<LHS,Op,RHS,EvalTag> This_t;


    //


    // Construct from an Expr.


    // Build the kernel that will evaluate the expression on the 


    // given domain.


    // Acquire locks on the data referred to by the expression.


    //


    ExpressionKernel(const LHS&,const Op&,const RHS&,


    Pooma::Scheduler_t&);


      


      


    virtual ~ExpressionKernel();


    


    // Do the loop.


    virtual void run();


    


  private:


      


    // The expression we will evaluate.


    LHS lhs_m;


    Op  op_m;


    RHS rhs_m;


    TAU_MAPPING_OBJECT(TauMapFI)
};
