The current challenge is not whether we will achieve an exaflop by 2018, but whether we can do it in less than 20 megawatts. The SCAPE Laboratory at Virginia Tech has been studying the tradeoffs between performance and power for over a decade. We've developed an extensive tool chain for monitoring and managing power and performance in supercomputers. We will discuss the implications of our findings for exascale systems and some research directions ripe for innovation. SUMMARY:The Growing Power Struggle in HPC PRIORITY:3 END:VEVENT END:VCALENDAR
