Extreme scale computing: Challenges and opportunities

Abstract

An extreme scale system is one that is one thousand times more capablethan a current comparable system, with the same power and physicalfootprint. Intuitively, this means that the power consumption andphysical footprint of a current departmental server should be enough todeliver petascale performance, and that a single, commodity chip shoulddeliver terascale performance. In this panel, we will discuss theresulting challenges in energy/power efficiency, concurrency andlocality, resiliency and programmability, and the research opportunitiesthat may take us to extreme scale systems.
