User-defined Events

Besides timers and phases that measure the time spent between a pair of start and stop calls in the code, TAU also provides support for user-defined atomic events. After an event is registered with a name, it may be triggered with a value at a given point in the source code. At the application level, we can use user-defined events to track the progress of the simulation by keeping track of application specific parameters that explain program dynamics, for example, the number of iterations required for convergence of a solver at each time step, or the number of cells in each iteration of an adaptive mesh refinement application.
