Name
TAU_MAPPING_PROFILE_START — Starts a mapping timer
Synopsis
C/C++:
TAU_MAPPING_PROFILE_START( |
timer, | |
tid) ;
|
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. }
