Summary
The US, Europe, Japan and China are racing to develop the next generation of supercomputers - exascale machines capable of 10 to the 18th power calculations a second - by 2020. But the barriers are daunting: the challenge is to change the paradigm of high-performance computing.The 2012 biennial high performance workshop, held in Cetraro, Italy in June 2012, focused on the challenges facing the computing research community to reach exascale performance in the next decade. This book presents papers from this workshop, arranged into four major topics: energy, scalability, new architectural concep
