In our simple model the memory system is a linear array of bytes and the CP U can access each memory location in a constant amount of time While this is an effective model as f ar as it goes it does not re64258ect the way that modern systems really COS 116, Spring . 2012.

Intel Labs Pittsburgh. September 22, 2011. Abstract. The . goal of the Hi-Spade project is to enable a hierarchy-savvy approach to algorithm design and systems for emerging parallel hierarchies. Good performance often requires effective use of the cache/memory/storage hierarchy of the target computing platform. Two recent trends---pervasive multi-cores and pervasive flash-based SSDs---provide both new challenges and new opportunities for maximizing performance. The project seeks to create abstractions, tools and techniques that (. 10 Nov, 2015. Instructor:. . Rabi Mahapatra. Slide Source: Randal E. Bryant and David R. . O’Hallaron. Today.
