Getting Up to Speed: The Future of Supercomputing

In the US. the NRC is probably the best qualified to assess where supercomputing is going. The book offers a vendor neutral survey. One that is also largely country neutral. The latest status of various hardware efforts is described. For vector computing, massive clustering, and other approaches. The latter also includes the ongoing competition between building a supercomputer out of common off the shelf components (COTS), or via designing dedicated hardware. You might wonder at the continued viability of the latter, as design limits keep getting pushed back. Surely a point of diminishing returns will be reached?
