NAME¶

TAU_MAPPING_PROFILE_TIMER - Declares a mapping timer

SYNOPSIS¶

C/C++:

TAU_MAPPING_PROFILE_TIMER(Profiler timer, FunctionInfo *FuncIdVar);

DESCRIPTION¶

TAU_MAPPING_PROFILE_TIMER enables timing of individual statements, instead of complete blocks. It will attribute the time to a higher-level statement. The second argument is the identifier of the statement that is obtained after TAU_MAPPING_OBJECT and TAU_MAPPING_LINK have executed. The timer argument in this macro is any variable that is used subsequently to start and stop the timer.

EXAMPLE¶

C/C++ :

template<class LHS,class Op,class RHS,class EvalTag>
void
ExpressionKernel<LHS,Op,RHS,EvalTag>::run() {


  TAU_MAPPING_PROFILE_TIMER(timer, TauMapFI);


  printf("ExpressionKernel::run() this = 4854\n", this);


  // Just evaluate the expression.


  


  TAU_MAPPING_PROFILE_START(timer);


  KernelEvaluator<EvalTag>().evaluate(lhs_m, op_m, rhs_m);


  TAU_MAPPING_PROFILE_STOP();


  // we could release the locks here instead of in the dtor.
}
