TAU_MAPPING_PROFILE_(3)

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.
    }
