Name
TAU_MAPPING_PROFILE_TIMER — Declares a mapping timer
Synopsis
C/C++:
TAU_MAPPING_PROFILE_TIMER( |
timer, | |
FuncIdVar) ;
|
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. }
