HPC 2012 Contents Contents Welcome

Welcome to the first edition of our high-performance computing yearbook, HPC 2012. As the team behind Scientific Computing World, we have the privilege of reporting on the technological advances that change the face of HPC, as they happen. Many of these changes have a profound impact on science and engineering, as well as society more widely, and with that in mind we hope that this annual publication will offer a distinctive view of the industry, providing insight into today’s, and a guide to tomorrow’s, achievements. We begin by taking a behind-the-scenes look at the challenges
