For now, applications dealing with seismic noise (signal collected between
earthquakes, more than 99% of the data) or major earthquakes are taking
advantage of the grid facilities:
- average seismic noise level per day over the past years is computed
- polarized noise and source determination also over the past years.
Although much more demanding on CPU time, this was achieved...

The candidate solutions found in AE are used to generate "offsprings" based on their fitness values; fitter candidates generating more offsprings into the next generation. This makes the entire computational requirements tend to be proportional to that of evaluating a single individual. Hence, the fitness evaluations of candidate solutions need to be spread over a large number of processors to...
