Viewing posts from December, 2012
The start of December is when the International Electron Devices Meeting IEDM traditionally takes place. Next to the presentation of numerous new designs (with and without silicon), its agenda always includes an overview of the latest process technology.
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.
