Really? The times I have visited ORNL, they've pretty much talked non-stop about all the fun things being done on Titan. I am/was affiliated with CASL and used it for some of my research work. It's a nice system and we got amazing performance, it would have taken literally years to run the same calculations back on the cluster at my university. We didn't really take full advantage, though, as we weren't using the coprocessors. But I guess our mission is computational science, so maybe that's why we heard so much about it. I just saw the most interesting presentation the other day. Tom Evans' group is apparently working on these nice new methods to solve linear systems via Monte Carlo sampling. It's one of the projects in pursuit of exa-scale systems. The Monte Carlo algorithms are interesting because while they're a lot slower in terms of CPU hours, they do much better in terms of scaling and resiliency at those sorts of extremes.
