PPT-Trumping the Multicore Memory

Hierarchy with HiSpade Phillip B Gibbons Intel Labs Pittsburgh September 22 2011 Abstract The goal of the HiSpade project is to enable a hierarchysavvy approach to algorithm design and systems for emerging parallel hierarchies Good performance often requires effective use of the cachememorystorage hierarchy of the target computing platform Two recent trendspervasive multicores and pervasive flashbased SSDsprovide both new challenges and new opportunities for maximizing performance The project seeks to create abstractions tools and techniques that .
