Summary <strong>and</strong> Requirements<br />
Challenge 1: Internal Wave Mix<strong>in</strong>g<br />
Needs global or bas<strong>in</strong>-scale ocean model (physics only) of order<br />
1 km resolution, run for periods of order 30-40 years.<br />
Challenge 2: Global Carbon Cycle<br />
Needs global physics <strong>and</strong> biology ocean model, at highest achievable<br />
resolution (1/4 or 1/12°) run for periods of order 1,000 years or more.<br />
Challenge 3: <strong>Climate</strong> Uncerta<strong>in</strong>ty<br />
Needs coupled climate models at best possible resolution (e.g. 1 or 0.5°)<br />
run for periods of order 100-1000 years, but up to 1,000 times (or more).<br />
These challenges clearly have very different requirements <strong>in</strong> terms of<br />
number of po<strong>in</strong>ts per cpu node, amounts of data exchange between<br />
nodes, <strong>and</strong> amounts of IO etc. Also, critically, each challenge needs<br />
significant extra manpower, which is currently lack<strong>in</strong>g.<br />
Some may be more easily achievable than others - Discussion needed.
