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.
