About the Event
Soon we may have processors with over ten billion transistors organized into hundreds of cores delivering supercomputer-like TeraFlops performance. To unlock this performance potential, however, we need dramatic improvements in processor efficiency to stay within the strict power budget. A significant source of inefficiency in today's general-purpose processors is that they tend to expend equal resources to varied applications without accounting for their individual needs. In this talk, I will present two solutions to address such inefficiency in both core and un-core parts of the processor. Composite cores eliminate needless power expended by out-of-order cores for applications with little or easy to exploit instruction-level parallelism. Aergia on-chip network prioritizes packets of network-sensitive applications to attain significantly higher throughput. I will also briefly discuss our on-going research that seeks to move compute close to storage in order to attain orders of magnitude improvement in efficiency for Big Data applications.
