According to recent news reports, Titan, the Cray XK7 located at the Department of Energy’s Oak Ridge National Laboratory and currently sitting at the top of the Top500 List, “isn’t working like it should”.  This has puzzled many folks in the HPC community.  How could Titan win the Top500 race last November, but be reported in February to have “bugs” that have “prevented users from getting access to the full Titan so far”?

Some details are beginning to emerge, and the folks at Oak Ridge do expect Titan to pass its acceptance testing after Cray finishes repairing it.  However, this situation does serve to raise some interesting questions about the Top500 List – and, in particular, about some pieces of the Top500 puzzle that are requested by the List keepers but are absent from the List.  Let’s take a closer look.

By current estimates, we’re about a decade away from having exascale computing capability. That’s a pretty long time, especially in our world of HPC. What will the world be like in 2022?  What form will exascale computing take when it’s real? These are difficult questions to answer. Never before has the HPC community focused so intensively on a machine so far beyond its grasp. Nevertheless, stalwart cadres around the globe are drafting strategies, plans, and roadmaps to get from here to exascale.

So, what about the rest of us? Are there useful things we could do while waiting – or instead of waiting – for exascale? Perhaps there are. Let’s take a look at a few possibilities.

The semi-annual HPC “500 list” time and its attendant fall iron horse racing season are upon us. Thanks to the hard work of the list keepers, we currently enjoy three major ones to review, compare and contrast: TOP500, Green500 and Graph 500. Each focuses on a distinct aspect of HPC – number crunching, energy efficiency, and data crunching, respectively – and together they allow us to construct our own type of Triple Crown. Since new race results were recently announced, let’s take a look at the current standings.
