Description
C/C++ :
With TAU_PROFILE_TIMER, a group of one or more
statements is profiled. This macro has a timer variable as its first
argument, and then strings for name and type, as described earlier. It
associates the timer to the profile group specified in the last
parameter.
Fortran :
To profile a block of Fortran code, such as a function, subroutine,
loop etc., the user must first declare a profiler, which is an integer array
of two elements (pointer) with the save attribute, and pass it as the first
parameter to the TAU_PROFILE_TIMER subroutine. The second
parameter must contain the name of the routine, which is enclosed in a single
quote. TAU_PROFILE_TIMER declares the profiler that must
be used to profile a block of code. The profiler is used to profile the
statements using TAU_PROFILE_START and
TAU_PROFILE_STOP as explained later.
Example
C/C++ :
template< class T, unsigned Dim >
void BareField<T,Dim>::fillGuardCells(bool reallyFill)
{y
// profiling macros
TAU_TYPE_STRING(taustr, CT(*this) + " void (bool)" );
TAU_PROFILE("BareField::fillGuardCells()", taustr, TAU_FIELD);
TAU_PROFILE_TIMER(sendtimer, "fillGuardCells-send",
taustr, TAU_FIELD);
TAU_PROFILE_TIMER(localstimer, "fillGuardCells-locals",
taustr, TAU_FIELD);
...
}
