Software to simulate tsunami generation and propagation in context of early warning systems. There are three different sizes taking progressively longer time. In the chart below most of the time is spent on the third and very little on the first. This runs mostly on all cores.
Topdown profile shows almost all time spent in backend stalls with a low retirement rate and low frontend stalls.
AMD metrics confirm running on all cores, floating point application and 78% of the time in backend memory stalls. There is also a moderate branches.
