Simple Ideas

While many academics strive for complex solutions, I am proud of my simple ideas.

  1. Adds a simple multicore hardware corollary to Amdahl's Law.

    Amdahl's Law in the Multicore Era,
    Mark D. Hill and Michael R. Marty,
    IEEE Computer, July 2008.

    Original Technical Report (UW CS-TR-2007-1593, April 2007): pdf

  2. Argues why sequential consistency may be better than relaxed memory consistency models.

    Multiprocessors Should Support Simple Memory Consistency Models,
    Mark D. Hill,
    IEEE Computer, August 1998.
    Local copy: pdf
    2003 Dagstuhl Retrospective Talk: ppt

  3. Shows that parallel computing is cost-effective whenever "speedup" exceeds "costup."

    Cost-Effective Parallel Computing,
    David A. Wood and Mark D. Hill,
    IEEE Computer, February 1995.
    Paper: final scanned pdf and near-final latex pdf.

  4. Shows that fast hits for direct-mapped caches can lead to better performance than for set-associative caches.

    A Case for Direct-Mapped Caches,
    Mark D. Hill,
    IEEE Computer, December 1988.
    Paper: scanned pdf (2 MB)

  5. Partitions cache misses into the 3Cs: compulsory, capacity, and conflicts misses (but the rest of the paper is complex).

    Evaluating Associativity in CPU Caches,
    Mark D. Hill and Alan Jay Smith,
    IEEE Transactions on Computers (TOC), December 1989.
    Paper: scanned pdf.
