Titan, the Cray XK7 at the Oak Ridge National Lab that debuted last fall as the fastest supercomputer in the world with 17.59 petaflops of sustained computing power, will rely on its previous LINPACK test for the upcoming edition of the Top 500 list.
At 31 petaflops of sustained LINPACK capacity, the new Chinese Tianhe-2 supercomputer will be the fastest supercomputer in the world when this month’s Top 500 list comes out, as we reported previously in HPCwire.
Gearing up for ISC’13, contributor Miha Ahronovitz examines where HPC has been and where it’s headed. In this in-depth interview, Drs. Hans Meuer and Horst Gietl recount the origins of the TOP500 list and wax prophetic on the future of supercomputing, including the peril and promise of parallel programming as well as the long-term shift away from compute centrism.

But every year, some of the data requested by the organizers is missing. And wouldn’t it be a good idea to add some new data points to the list?
If you have an office betting pool about which college students are likely to win the next cluster challenge, here are some things you should know.
Comments made by Blue Waters Project Director Bill Kramer questioning the continued relevance of the TOP500 list prompt this letter to the editor.

HPCwire spoke with Project Director Bill Kramer to get the full story on this important decision.

The GPU-charged Titan, using the new NVIDIA K20X-equipped XK7 blades from Cray, delivered 17.6 petaflops to Sequoia’s 16.3 petaflops on Linpack, the sole metric for TOP500 rankings.
DOE lab is taking applications from researchers who want time on 8-petaflop super.
