Abstract :
The global race to build more powerful supercomputers is focused on the next big milestone: a supercomputer capable of performing 1 million trillion floating-point operations per second (1 exaflops). Such a system will require a big overhaul of how these machines compute, how they move data, and how they???re programmed. It???s a process that might not reach its goal for eight years. But the seeds of future success are being designed into two machines that could arrive in just two years.
