TAU_MAPPING_PROFILE(3)
Profiles a block based on a mapping
SYNOPSIS
C/C++:
-
TAU_MAPPING_PROFILE(FunctionInfo *FuncIdVar);
DESCRIPTION
The
TAU_MAPPING_PROFILE
macro measures the time and attributes it to the statement mapped in
TAU_MAPPING
macro. It takes as its argument the identifier of the higher level statement that is stored using
TAU_MAPPING_OBJECT
and linked to the statement using
TAU_MAPPING_LINK
macros.
TAU_MAPPING_PROFILE
measures the time spent in the entire block in which it is invoked. For example, if the time spent in the run method of the class does work that must be associated with the higher-level array expression, then, we can instrument it as follows:
EXAMPLE
C/C++ :
// Evaluate the kernel
// Just tell an InlineEvaluator to do it.
template<class LHS,class Op,class RHS,class EvalTag>
void
ExpressionKernel<LHS,Op,RHS,EvalTag>::run() {
TAU_MAPPING_PROFILE(TauMapFI)
// Just evaluate the expression.
KernelEvaluator<EvalTag>().evalate(lhs_m,op_m,rhs_m);
// we could release the locks here or in dtor
}
