NAME

       TAU_MAPPING_PROFILE_START - Starts a mapping timer

SYNOPSIS

       C/C++:

       TAU_MAPPING_PROFILE_START(Profiler timer, int tid);

DESCRIPTION

       TAU_MAPPING_PROFILE_START starts the timer that is created using
       TAU_MAPPING_PROFILE_TIMER. This will measure the elapsed time in groups of statements,
       instead of the entire block. A corresponding stop statement stops the timer as described
       next. The thread identifier is specified in the tid parameter.

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.
       }
