TAU_CONTEXT_EVENT (3)

C/C++: TAU_CONTEXT_EVENT(TauUserEvent variable, double value);

Fortran: TAU_CONTEXT_EVENT(integer variable(2), real value);

Triggers a context event. A context event associates the name with the list of routines along the callstack. A context event tracks information like a user defined event and TAU records the maxima, minima, mean, std. deviation and the number of samples for each context event. A context event helps distinguish the data supplied by the user based on the location where an event occurs and the sequence of actions (routine/timer invocations) that preceeded the event. The depth of the the callstack embedded in the context event's name is specified by the user in the environment variable TAU_CALLPATH_DEPTH. If this variable is not specified, TAU uses a default depth of 2.

C/C++ :

int f2(void)
{
  static int count = 0;
  count ++;
  TAU_PROFILE("f2()", "(sleeps 2 sec, calls f3)", TAU_USER);
  TAU_REGISTER_CONTEXT_EVENT(event, "Iteration count");
/*
  if (count == 2)
    TAU_DISABLE_CONTEXT_EVENT(event);
*/
  printf("Inside f2: sleeps 2 sec, calls f3\n");

  TAU_CONTEXT_EVENT(event, 232+count);
  sleep(2);
  f3();
  return 0;
}

Fortran :

integer memevent(2) / 0, 0 /
save memevent
call TAU_REGISTER_CONTEXT_EVENT(memevent, "STORAGEARY mem allocated')
call TAU_CONTEXT_EVENT(memevent, SIZEOF(STORAGEARY)*sizeof(INTEGER))
