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.
