  <p>This doesn't give a complete answer, but it would suggest that if you could find an estimated time for the Tianhe-2 to generate a 7-man tablebase and then multiply that result by 100, you should get a ballpark figure for the time required, probably accurate to within an order of magnitude.</p>
