Name
TAU_MAPPING_OBJECT — Declares a mapping object
Synopsis
C/C++:
TAU_MAPPING_OBJECT(FuncIdVar);
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)
