NAME¶
TAU_PROFILE_TIMER - Defines a static timer.
SYNOPSIS¶
C/C++:
TAU_PROFILE_TIMER(Profiler timer, char* or string& function_name, char* or string& type, TauGroup_t group);
Fortran:
TAU_PROFILE_TIMER(integer profiler(2), character name(size));
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) {
// 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);
... }
Fortran :
subroutine bcast_inputs implicit none integer profiler(2) save profiler include 'mpinpb.h' include 'applu.incl' interger IERR call TAU_PROFILE_TIMER(profiler, 'bcast_inputs')
